59p iPhone stethoscope is a life saviour





The stethoscope, the 200-year-old accessory without which no doctor is complete, could soon be replaced by the humdrum mobile phone.

A computer scientist who wrote a program that turns an Apple iPhone into a stethoscope has made a major advance in medical technology and created a sensation among heart specialists. The application, called iStethoscope, was developed as a "bit of fun", and has become a runaway success after being downloaded millions of times by users across the world.

Cardiologists say the software has saved lives and brought specialist expertise within reach of patients in remote parts of the world. Heart sounds can be recorded and emailed to doctors anywhere for an expert opinion.

Peter Bentley, a researcher who developed the application in the computer science department at University College, London, said he was amazed by the response.

"The idea began as an experiment," he added. "I had a new, popular science book out last year and I wanted to see if I could tell people about the book using a free iPhone application that did something useful.

"It was intended as a fun toy but to my astonishment it was downloaded by several million people all over the world in the first six months. Then I started receiving emails, phone calls and visits from cardiologists all over the world. They said it worked better than commercially available digital stethoscopes. They were tremendously excited. One flew over from the US just to discuss it with me."

The cause of the doctors' excitement was that the audio quality from the iPhone was far superior to that from digital stethoscopes. Mobile phones are a huge market compared with digital stethoscopes, and economies of scale mean they are made with better hardware.

Responding to requests from specialists, Mr Bentley extended the application to allow heart sounds to be recorded, emailed and analysed. The application costs 59p to download, but cardiologists say it does a better job than equipment costing thousands of times as much.

Glenn Nordehn, a US cardiologist researcher and specialist in digital stechoscopes at the University of Minnesota, said: "This is the best thing to come around in terms of medical equipment for a very long time. [His] closest competitor charges about 3,000 times as much"

Mr Bentley is now working on further iPhone applications, such as an electrocardiogram reader. "This is the way everyone wants to go," he said.

SQUARE: From the founder of Twitter





From CNN:

Twitter creator Jack Dorsey Wednesday gave the first public demonstration of his hotly-anticipated latest venture -- a device to allow credit card payments by cell phone -- and revealed it would be given away for free.

Details of "Square" -- a card reader which plugs into the headphone socket of most mobile devices -- have been circulating on the Internet since it was announced earlier this month, but little has been known about how it works or who it was aimed at.

However, Dorsey -- whose microblogging Web site has proved hugely popular but not hugely profitable since launching in March 2006 -- gave no explanation on how he would make money from his new creation, beyond revealing there would be a per-transaction charity donation.

Square, a tiny cube about an inch in length, contains a magnetic strip reader that allows users to swipe and read credit cards, then deduct payment on or offline through a downloaded application that communicates with card issuers in the same way as retailer devices.

Customers then use their finger on the phone's touch-recognition screen to sign their name to the transaction.

Dorsey, Twitter's co-founder and chairman, says the device, scheduled for launch on iPhones and iPods in March 2010, was inspired partly by the "immediacy, approachability and transparency" of Twitter and by the global economic crisis which has exposed a need for a radical rethink of the financial sector.

Bangladesh: Learn English on your Mobile

More than 300,000 people in Bangladesh, one of Asia’s poorest but fastest-growing economies, have rushed to sign up to learn English over their mobile phones, threatening to swamp the service even before its official launch on Friday.

The project, which costs users less than the price of a cup of tea for each three-minute lesson, is being run by the BBC World Service Trust, the international charity arm of the broadcaster. Part of a UK government initiative to help develop English skills in Bangladesh, it marks the first time that mobile phones have been used as an educational tool on this scale.

Since mobile-phone services began in Bangladesh just over a decade ago, more than 50.4m Bangladeshis have acquired phone connections, including many in remote rural areas. This far outnumbers the 4m who have internet access.

English is increasingly seen as a key to economic mobility. An estimated 6.2m Bangladeshis work overseas and hundreds of thousands of others want to follow in their steps. However, English is also important for securing jobs at home, where about 71 per cent of employers look for workers with “communicative English”.

Through its Janala service, the BBC offers 250 audio and SMS lessons at different levels. Each lesson is a three-minute phone call, costing about 3 taka (2.6p).

One basic lesson involves listening to and repeating simple dialogue like: “What do you do?” “I work in IT, what about you?” “I’m a student.” “That’s nice.” Another is devoted to differentiating vowel sounds like those in ship and sheep or leaf and live.

All six mobile phone operators in Bangladesh have agreed to cut the cost of calls to the service by 50 per cent to make it more affordable. Ms Chamberlain said the project team was in talks with the mobile phone companies to increase capacity to cope with the unexpectedly high demand.

The launch of the service comes just weeks after Grameenphone, the country’s largest mobile phone operator, held Bangladesh’s largest IPO, raising $71m from retail investors in the largest offering ever held in the country.

The language lessons are mainly targeting 18 to 24-year-olds, who typically had five or more years of formal education, but whose training in English had been weak. The target market is people living on less than 10,000 taka ($145, €97, £87) a month, who would struggle to pay for formal English lessons.

The relatively low cost of mobile handsets and connection charges has led to an explosion in their use and an estimated 50 million people now have access to phones.

Now users will be able to listen via their phones to weekly bilingual ­English language lessons and receive lessons by text as part of a low-cost service. Lessons are available at four levels, ranging from basic conver­sation skills, to support with sounds that Bangladeshis find difficult to pronounce, and the higher-level vocabulary of English language news media.

New lessons will be available each week with older lessons accessible from an archive. Learners can also ­assess their skills by doing audio quizzes and tests delivered by text message.

The trust says that it has negotiated reductions on standard mobile tariffs of up to 75% to make the service affordable to users with limited incomes.

Allan Freedman, country director for BBC World Service Trust Bangladesh, said: “Young people across Bangladesh have told us they consider learning English as a path to better jobs and opportunities. Our project is about meeting that demand and helping millions of people access English learning tools for the first time.

“It’s arguably the most exciting use of English to improve the lives of ­people in the developing world today.”

The Janala lessons will also be available via the internet on a ­website designed to develop both English-­language and web-user skills, in a country where computer use has been severely restricted by high costs and lack of electricity in rural areas.

Janala will also be promoted via a weekly television programme, BBC Buzz, produced by the World Service Trust, which started broadcasting last month. The show features stories aimed at younger viewers and covers topics such as careers, politics, fashion and music.

It includes the English language learning exploits of a cartoon character called Rinku. Viewers can receive follow-up lessons via mobile phone that build on language points raised by Rinku and have a say on future ­episodes.

Wavesecure: Helping track lost phones


Siliconindia organized Mobile Applications Conference (MAC) on October 31, where 25 mobile companies exhibited their applications and presented their business plans in NIMHANS (National Institute of Mental Health and Neuro Sciences) convention center, Bangalore, in front of around 400 people and entrepreneurs. Industry leaders within the mobile space also put some light on where the industry is headed and how entrepreneurs and developers can take advantage.

TenCube, whose anchor product, WaveSecure, is the market leading mobile security suite recognized by customers and analysts, won the best mobile application award. TenCube was the unanimous choice of judges as well as the audience. It got 71 votes followed by Eterno Infotech and Divium, which got 37 and 36 votes respectively. Originally developed for police and military use in Singapore, WaveSecure has become Nokia's preferred mobile security product, chosen to be bundled into millions of premium Nokia devices. It is also the preferred security service selected by leading operators like Telenor and SingTel for their subscribers.

Very interesting FAQ's for those interested.

Over-the-top (OTT) Applications and Services

I keep on hearing about OTT apps everywhere I go nowadays. I know roughly what they mean but I couldnt find a proper definition anywhere. Here is my attampt to write a bit about what OTT means.

Traditionally lots of services like Voice and Television for example is delivered in a conventional way where Voice was transferred via a PSTN or a Mobile network and similarly TV was delivered via Cable, Satellite, DVB-T kind of technology. With Internet becoming common and Broadband access available to everyone, easily and cheaply, new applications are available to deliver Voice and TV kinds of services. The most popular voice app is for example Skype and Youtube is an example of TV (even though its more like Video On Demand)

These apps cause two main problems. The first problem is that the companies using this traditional medium starts losing customers and their cost per person goes up forcing their profits down. At the same time the amount of data traffic for the ISP increases thereby increasing the number of bits/cent (bits/pence). This forces them to upgrade their infrastructure to provide the same quality of service (QoS).

What this would mean is that in future it would not be possible to get flat rate packages for Mobile broadband or there may be restrictions where certain applications wont run unless you pay extra.

The dilemma for carriers is that LTE’s all-IP architecture will create a more open environment for Over The Top (OTT) applications, including third-party VoIP services, which threaten to further commoditize the network. To overcome this threat and realize revenue gains from LTE, carriers will need to partner with content and application providers, develop application store-fronts such as Apple’s App Store, and perhaps deploy APIs that expose LTE’s value-added network capabilities to third-party application and content developers for a fee.

The only way to ensure profitability in this ‘cost-per-bit’ model is to maximise scale. We have seen this clearly in mobile telephony, where a lack of differentiation has led to intense price pressure, flat rate tariffs and a decoupling of the revenues from the costs. The mobile operator suffers the cost of deploying ever increasing bandwidth while the ‘value’ that this bandwidth enables – the access to over the top (OTT) applications and services benefits the OTT providers.

To avoid this commoditisation, service providers need to add intelligence to the way they deliver these bits. Adopting a ’value-per-bit’ strategy ensures that the value added over and above the simple transport of data is seen and desired by the consumer and by any upstream content or application provider.

This creates a tighter coupling between infrastructure costs and the revenue that infrastructure can attract, thereby ensuring a far more sustainable business model for the service provider. It also benefits consumers and application providers by providing them levels of security, performance and reliability appropriate to the transaction being carried out and the subscribed service.

Most of us wouldn’t dream of paying for a customized Internet experience on a tailor-made device from our broadband service provider. But that is the way we used to buy telephone service, and it continues to be the way we do things for mobile and video services. Over time, all of these businesses will follow a similar pattern, breaking down into their component parts so that the best adapted players win in each piece of the business. The only questions are: “Who are the best adapted?” and “How long will it take?”

Google's strategy for winning in a nutshell

Interesting analysis by Zigurd Mednieks on his blog 4thscreen. Though not directly linked to mobiles, I am sure a similar approach is being taken for mobiles.

Google wants to enable Google applications to run as well as possible as many places as possible. Here is how:

Google applications: Web applications run in browsers, on all kinds of systems. No need to be installed or updated, and hard to block. Anyone with IE, Firefox, Safari, Opera, or, of course, Chrome has access to all the latest applications.

Gears: Web applications run in a sandbox and don't have much access to your system. Gears enables more access. Applications are still in a sandbox, but the Gears-enabled sandbox is bigger, and can persist. This frees Web applications from having to be connected all the time.

GWT: The Google Web Toolkit (GWT) is a radical abstraction of of the browser runtime environment. GWT applications are written in Java and compiled to JavaScript. The GWT library provides fixes for incompatibilities between browsers, as well as a rich UI library.

Chrome: Google's browser. Chrome provides the ideal browser runtime environment for Google applications. Fast JavaScript execution. Separate processes for each Web page.

Chrome Frame: Chrome Frame puts the Chrome browser inside Internet Explorer. This shows the lengths Google will go to in order to give Google applications the best possible runtime environment is as many situations as possible.

Android: Android is a Linux-based OS for mobile handsets and other devices. Android has exploded in popularity among handset manufacturers. This is Google's first win in computing platforms, and Google influences the software “stack” all the way down to the hardware. Android has a Webkit-derived browser.

Chrome OS: Chrome OS is meant for things larger than handsets. Chrome will be Google's attempt to bring a Linux-based OS and Web-based applications to netbooks and PCs.

Google's strategy is comprehensive: Control the software all the way down to the hardware where possible, and, if that isn't possible, be compatible, and maximize capabilities, on every possible platform.

Google's strategy is also technologically coherent: Java, Linux, Webkit, SQLite, Eclipse, and other common components are reused across multiple Google products and platforms. You can expect Google to contribute to and influence the development of these key ingredients. You can also see some design philosophy in common across Google products. For example, Android runs Java applications in multiple tasks, and Chrome runs Web pages/apps in multiple tasks to make these systems resilient to apps that crash.

While Google's applications, like Gmail, are proprietary, Android, Chrome, Gears, GWT and many other components of Google's strategy are open source software, many with permissive licensing that would not preclude competitors from using them. Open source builds confidence in Google's partners and in software developers using Google platforms.

Google's strategy has formed recently and moved quickly. It can be hard to perceive the impact. As fast as Google is implementing this strategy, you can expect a similarly fast emergence of an application ecosystem around Google's strategy. This will be one of the most significant developments in software in the coming years.

Meanwhile google has recently added search options to mobiles. You can now search only forums and you can search for posts that were posted within last week. Very powerful feature but shame so many PC users dont even know hot to use them.

Another very interesting feature that has been added is that when you search using desktop, you will be able to see that in your search history in mobiles as well. Google now synchs between your desktop and mobile as long as you have iPhone, Android or Palm phone.

I wonder how will Google surprise us next.

Beyond Voice: New uses for mobile phones could launch another wave of development

The Economist recently published a special report on Telecoms in Emerging markets which is available here. The following is an extract from that.

In a field just outside the village of Bumwambu in eastern Uganda, surrounded by banana trees and cassava, with chickens running between the mudbrick houses, Frederick Makawa is thinking about tomatoes. It is late June and the rainy season is coming to an end. Tomatoes are a valuable cash crop during the coming dry season and Mr Makawa wants to plant his seedlings as soon as possible. But Uganda’s traditional growing seasons are shifting, so he is worried about droughts or cash foods that could destroy his crop. Michael Gizamba, a local villagephone operator, offers to help using Farmer’s Friend, an agricultural information service. He sends a text message to ask for a seasonal weather forecast for the region. Before long a reply arrives to say that normal, moderate rainfall is expected during July. Mr Makawa decides to plant his tomatoes.

The Farmer’s Friend service accepts text message queries such as "rice aphids", "tomato blight" or "how to plant bananas" and dispenses relevant advice from a database compiled by local partners. More complicated questions ("my chicken’s eyes are bulging") are relayed to human experts, who either call back within 15 minutes or, with particularly diffcult problems, promise to provide an answer within four days. These answers are then used to improve the database.

Farmer’s Friend is one of a range of phone based services launched in June by MTN, Google and the Grameen Foundation’s "Application Laboratory", or AppLab. As well as disseminating advice in agriculture, provided by the Busoga Rural Open Source and Development Initiative, the new services also provide health and market information. The Clinic Finder service points people to nearby clinics, and the Health Tips service explains the symptoms of common diseases.

Lastly there is Google Trader, a textbased system that matches buyers and sellers of agricultural produce and commodities. Sellers send a message to say where they are and what they have to offer, which will be available to potential buyers within 30km for seven days. Mr Makawa says his father used the service to look for a buyer for some pigs, which he sold to pay school fees. These services cost 110 shillings ($0.05) a time, the same as a standard text message, except for Google Trader, which costs double that. In their first five weeks the services received a total of more than 1m queries.

As with the Village Phone project, Grameen is trying to establish a model that can be scaled up and replicated in other countries. Offering agricultural and health information is more diffcult than offering a phone service, however, because such information must be localised and must take cultural di?erences into account.

Grameen’s collaboration with MTN and Google in Uganda is just one of dozens of services across the developing world that offer agricultural, market and health information via mobile phones. In India, for example, farmers can sign up for Reuters Market Lite, a textbased service that is available in parts of India. Its 125,000 users pay 200 rupees ($4.20) for a threemonth subscription, which provides them with local weather and price information four or five times a day. Many farmers say that their profits have gone up as a result.

Tata Consultancy Services, an Indian operator, offers a service called mKrishi which is similar to Farmer’s Friend, allowing farmers to send queries and receive personalised advice. "The rural population is willing to pay substantial subscription fees to get this information multiple times a day", says Kunal Bajaj of BDA. There have been lots of pilot schemes in the past, he says, but commercial offerings are now beginning to gain ground.

Nokia, the world’s largest handsetmaker, launched its own information service, Nokia Life Tools, in India in June. In addition to education and entertainment, it provides agricultural information, such as prices, weather data and farming tips, that can be called up from special menus on some Nokia handsets. The basic service costs 30 rupees a month, and a premium service which provides detailed local crop prices in ten states is available at twice that price. "It is in its early stages, but it has resonated extremely well with its target audience," says OlliPekka Kallasvuo, Nokia’s chief executive.

Services to help farmers have been most widely adopted in China, where China Mobile offers a service called Nong Xin Tong in conjunction with the agriculture ministry, as part of its push into rural areas. It has already signed up 50m users and is aiming for 100m within three years. The service provides news, weather information and details of farming related government policies.

China Mobile also runs a website, 12582.com, that sends farmers information about planting techniques, pest management and market prices. The service, which costs two yuan ($0.30) a month, sends out 13m text messages a day and has over 40m users. There are dozens of other examples across the developing world.

TradeNet, launched in Ghana in 2005, now links buyers and sellers of agricultural products in nine African countries; CellBazaar provides a textbased classified ads service in Bangladesh.
Mobile phones are also being used in health care. Oneway text alerts, sent to everyone in a particular area, can be used to raise awareness of HIV; sending daily text messages to patients can help them remember to take their drugs for tuberculosis or HIV. Mobile phones can be used to gather health information in the field faster and more accurately than paper records and help with the management of drug stocks. Cameraphones are used to send pictures to remote specialists for diagnosis.

Quantifying the benefits of agricultural and health services is hard, and such services are still in their early days in much of the world. The mobile service that is delivering the most obvious economic benefits is money transfer, otherwise known as mobile banking (though for technical and regulatory reasons it is not, strictly speaking, banking). It has grown out of the widespread custom of using prepaid calling credit as an informal currency.

Suppose you want to send money from the city back to your family in the country. You could travel to the village and deliver I’m not selling for that the cash in person, but that takes time and money. Or you could ask an intermediary, such as a bus driver, to deliver the money, but that can be risky. More simply, you could buy a topup voucher for the amount you want to transfer (say, $10) and then call the villagephone operator or shopkeeper in your family’s village and read out the code on the voucher. The credit will be applied to the phone of the shopkeeper, who will hand cash to your family, minus a commission of 10-20%. In some countries, where airtime can be transferred directly from one phone to another by text message, the process is even simpler: load credit onto your phone, then send it to someone on the spot who in return gives cash to your intended recipient.

These methods became so widespread that some companies decided to set up mobile payment systems that allow real money, rather than just airtime, to be transferred from one user to another by phone. Once you have signed up, you pay money into the system by handing cash to an agent (usually a mobile operator’s airtime vendor), who credits the money to your mobilemoney account. You can withdraw money by visiting another agent, who checks that you have su?cient funds before debiting your account and handing over the cash.

You can also send money to other people, who will be sent a text message containing a special code that can be taken to an agent to withdraw cash. This allows cash to be sent from one place to another quickly and easily. The biggest successes in this field so far have been Gcash and Smart Money in the Philippines, Wizzit in South Africa, Celpay in Zambia and, above all, MPESA in Kenya, which has become the most widely adopted mobile money scheme in the world.

Launched in 2007 by Safaricom, Kenya’s largest mobile operator, it now has nearly 7m users. Not bad for a country of 38m people, 18.3m of whom have mobile phones. MPESA’s early adopters were young, male urban migrants who used it to send money home to their families in the country. But it has since become wildly popular and is used to pay for everything from school fees to taxis (drivers like it because it means they are carrying less cash around). Roughly $2m is transferred through the system each day, with an average amount of $20. ?In markets in Kenya, stallholders are happy to take MPESA payments.

"It’s pretty dramatic," says Bob Christen, head of the "Financial Services for the Poor" initiative at the Bill & Melinda Gates Foundation.

MTN’s launch of a mobile money service in Uganda in March 2009, in partnership with Stanbic Bank, provides further cause for optimism. MTN backed up its launch with a huge marketing campaign based around the simple idea of sending money home, as Safaricom had previously done in Kenya. After three months 60% of the population had heard of the service, a level of awareness that MPESA took a year to achieve, according to MTN. After four months the service had signed up 82,000 users. Of the $5.1m transferred in that period, half was in the fourth month, indicating a rapid take-off. MTN plans to increase the number of outlets that can handle mobile money to 5,000 by early 2010. MTN’s apparent success in Uganda seems to suggest that Kenya may not be a one-off after all. After fine-tuning its technology and procedures in Uganda, MTN plans to introduce the service in 20 other African and Middle Eastern countries; it has already launched in Ghana. Meanwhile Zain, which operates in several African markets, has started its own mobilemoney service, called Zap. According to CGAP, there will be over 120 mobilemoney schemes in developing countries by the end of 2009, more than double the number in 2008. By 2012, it predicts, some 1.7 billion people will have a mobile phone but no bank account, and 20% of them will be using mobile money.

Operators do not expect to make much money from mobile banking, says Mr Okoudjou, but it can help keep customers from defecting to rivals and cut costs by allowing people to top up their airtime directly on their phones, as well as providing wider social and economic benefits that reflect well on operators. Most importantly, he says, mobile banking can help the industry repeat the huge impact made when mobile phones were first introduced. "This is a second wave that can unleash the potential of mobile phones again," he says. "So we need to do this, and we need to do it properly, and we need to do it all over."

Net Neutrality: Good or Bad?



I am not sure what the right answer to this question is? There will be winners and losers in either case.

FCC (Federal Communications Commission) chairman Julius Genachowski has just outlined his much-awaited plan for Internet neutrality. If the plan is approved it would drag the wireless operators in the US into the public regulatory arena occupied by their wired cousins who have recently had to account for their neutrality policies to the FCC.

The proposed policy outlined today by Genachowski will mean the FCC will get to poke and pry into mobile operators' business policies and rule on how well they conform to FCC guidelines on neutrality in the same way that wiredtelcos must. The FCC will also impose new and tighter neutrality behaviour on the big phone companies including Verizon and AT&T.

In detail: Genachowski has reaffirmed the long-standing (since 2005) broadband principles that will now be formalised by the FCC.
  • That consumers are entitled to access the lawful Internet content of their choice.
  • That they are also entitled to run applications and use services of their choice, subject to the needs of law enforcement.
  • That they are entitled to connect their choice of legal devices that do not harm the network.
  • And that they are entitled to competition among network providers, application and service providers, and content providers.
Genachowski has added two extra principles. Internet access providers can't discriminate against particular Internet content or applications: and they must ensure that Internet access providers are transparent about the network management practises they implement.

"The rule-making process will enable the commission to analyse fully the implications of the principles for mobile network architectures and practises, and how, as a practical matter, they can be fairly and appropriately implemented," Genachowski said today.

U.S. phone companies may be forced to open their wireless networks to rival Internet services like Skype and Google Voice under the proposal. The proposal, if adopted, would be a victory for consumer advocates and big Internet companies like Google Inc at the expense of telecom operators like AT&T Inc, Verizon Communications and Sprint Nextel Corp.

"The risk to the wireless carriers is that they won't be able to stop customers from using free voice and text services like Skype or Google voice," said Bernstein analyst Craig Moffett. "Voice and text are where they make all of their money."

The FCC has already been examining why Apple Inc rejected Google Voice for use on iPhone, sold by AT&T.

The new proposal could result in mobile customers cutting their phone bills by opting for minimum carrier voice plans and doing without text-messaging plans if they use mobile voice and text services from Skype and Google.

Piper Jaffray analyst Christopher Larsen downplayed the risk, saying that if they have to, operators would be sure to find a way to change their fees in order to maintain profits.
Advocates of Net neutrality have long argued that service providers must be barred from blocking or slowing Internet traffic based on the content being sent or downloaded.


But service providers say the increasing volume of bandwidth-hogging services -- such as video sharing -- puts pressure on them as it requires active network management, and some argue that Net neutrality could stifle innovation.

AT&T, the No. 2 U.S. mobile service, said it was concerned about an extension of Net neutrality rules to the competitive mobile industry.

The new regulations would limit consumer choices and "affect content providers, application developers, device manufacturers and network builders," said an executive at Verizon, which owns the No. 1 mobile service with Vodafone Group Plc.

Wireless trade group CTIA, whose members include AT&T, Verizon Wireless and Sprint Nextel, said it was concerned the proposal would have "unintended consequences." Leading Cable provider Comcast Corp said it was pleased Genachowski "recognized that networks need to be managed."

Exactly my thoughts (but with proper technical terms, language and analysis ;) by Gary Kim in IP Communications:

In the communications business, rationing is a fact of network life. Since virtually every part of a communications network uses shared resources, and in a market where users do not want to pay too much for access to those resources, rationing of network resources is necessary.

Shared finite resources always pose a usage problem. Known as the "tragedy of the commons," the economic problem is that multiple individuals, acting independently, solely and rationally when using a common resource can ultimately destroy the shared limited resource.

Some people argue that this problem cannot exist with the Internet, which is virtually infinitely expansible. But that misses the point. In looking at shared resources, the "commons" is the access network's resources, primarily. In other words, the "choke point" is the homeowner's garden hose, not the reservoir.


Some might argue that IP technology, optics, Moore's Law and competition upend the traditional "scarcity" value of access bandwidth. Certainly it helps. Currently, most consumers have access to two terrestrial broadband providers, two satellite networks, three, possibly four mobile networks. Then, there are broadband pipes where people work, at school and at many retail locations.

Still, there are some physical and capital investment limits, at least at retail prices consumers seem willing to pay. If consumers are willing to pay much more, they can get almost any arbitrarily-defined amount of access bandwidth. That, after all, is what businesses do.

If consumers resist paying business prices, network investment has to be shared more robustly than it otherwise might.

Given that all network resources are shared, resources are finite. To support retail prices that require such sharing, networks are designed in ways that "underprovision" resources ranging from radio ports to multiplexers to backhaul bandwidth. Based on experience, network designers engineer networks to work without blocking or degradation most of the time, but not necessarily always. Unusual events that place unexpected load on any part of the access network will cause blocking.

Blocking, in other words, is a network management technique. And that's the problem the Federal Communications Commission is going to have as it looks at additional "network freedoms" rules commonly known as "network neutrality." The term itself is imprecise and in fact already covered by the existing FCC rules. One might argue the issue is more the definitions and applications of existing rules that require clarification.

The ostensible purpose of the new rules is to prevent access provider blocking or slowing of any lawful applications, but a rule exists for that. Instead, it appears a primary effect of the rules will be to extend wired network rules to wired providers.

Beyond that, policymakers will have to contend with tragedy of the commons effects. If, in forbidding any traffic shaping (a network management technique) in the guise of "permitting the free flow of bits," rulemakers might set the stage for dramatic changes in industry packaging and prices of Internet access and other applications and services.

U.S. consumers prefer "flat rate billing" in large part because of its predictability of cost. But highly differentiated usage, in a scenario where networks cannot be technically managed by any traffic prioritization rules, will lead to some form of metered billing.

If metered billing is not instituted, and if service providers cannot shape traffic at peak hours to preserve network access for all users, then heavy users either have to pay more for their usage patterns, they will have to change their usage patterns, or they might experience some equivalent of "busy hour blocking."

Application providers and "public policy advocates" seem to be happy that new network neutrality rules might be adopted. They might not be so happy if ISPs lose the ability to deny or slow access to network resources. On the voice networks, some actual call blocking is allowed at times of peak usage. Forcing users to redial might be considered a form of traffic shaping, allowing access, but at the cost of additional time, or time-shifted connections.

To the extent that such blocking rules already are impermissible, some other network management techniques must be used. And one way to manage demand is to raise its price, either by increases in flat-rate package prices, by instituting usage-based billing or some other functionally-similar policy.

To avoid the tragedy of the commons problem, in other words, requires raising the end user's understanding of cost to use the shared resource.

Prioritized traffic handling, which assigns users a lower priority in the network once they have reached their fair use level, might be a preferable traffic management technique to slowing any single user's connection, once their individual usage caps have been reached.

When that is done, heavy users experience degradation in service only when competing for resources in a congested situation. For peer-to-peer users, the experienced reduction in throughput will be limited over time.

Only in heavily loaded cells or areas will a peer-to-peer user experience serious issues. Prioritized traffic handling enables operators to focus on dimensioning their networks for normal usage, while still permitting unlimited or "all you can eat" traffic.

Perhaps there are other ways of handling the "rationing," but on a shared network with network congestion, available to users paying a relatively modest amount of money, while a highly-differentiated load being placed on the network by a small number of users, some form of rationing is going to happen.

Perhaps flat rate packaging might still be possible if rationing affects end user credentials, rather than bits and applications or protocols. In other words, instead of "throttling" a user's bandwidth when a pre-set usage cap is exceeded, what is throttled is access to the network itself.

CVs and Jobs via Souktel



A non-profit group in the occupied West Bank has started a scheme that uses mobile phone text messaging to help young Palestinians find work.

The group, based in Ramallah, has already registered 8,000 Palestinians on its Souktel system, most of them recent graduates. The system connects them to about 150 leading employers who are looking for staff.

Internet access in the West Bank remains low, reaching about one-third of the population. Most computer use is at internet cafes, which are largely male-dominated domains in what is still a conservative society.

Souktel enables young people looking for work to register by answering a series of simple questions in Arabic through text messages, which are used to create a mini-CV. They then receive regular information about relevant jobs on offer.

It costs little to use apart from a slight premium charged on each text sent. In the same way, employers can post notices about job vacancies and filter applications.

The project comes at a time when despite forecasts of improved economic growth in the West Bank, unemployment still stands at around 20%, with that figure even higher among young people.

The Palestinians are a highly educated population but the Israeli occupation in the West Bank, with checkpoints, roadblocks and frequent restrictions, makes it costly and difficult to travel and do business. Universities rarely offer careers advice.

You don't need an iPhone or to download software. It's just messaging and it works on a phone from 1995.

Souktel, an SMS service based in the Middle East and East Africa, is all about connections. The service, launched in 2006, uses SMS to connect users to everything from jobs and internships to humanitarian aid and youth leadership programs.

The name comes from "souk," the Arabic word for "marketplace," and "tel," or "telephone. Although at least 80 percent of people in Palestine have access to mobile phones, most people have Internet access only in cafés or public places, said Jacob Korenblum, co-founder of Souktel. "Getting information about medical care, jobs, and food bank services can be difficult," he said. And even at Internet cafes, Korenblum said that many people, especially women, lack access to these services. "We wanted to develop a very simple service," he said. "That's how Souktel started."

Korenblum who is Canadian, said that although he has been working in the aid sector since 2000, his personal interest in Palestine began in 2005. "I came to the West Bank to work for an NGO. The main things I realized was that there wasn't so much a lack of aid, but rather a lack of good ways to find out about it." Currently, Souktel is run by a team of six people, four of whom are Palestinian.

Souktel is a combination of two services -- JobMatch and AidLink. JobMatch is an SMS service that connects people seeking jobs with employers. Job seekers can register via SMS with Souktel, and then, through a series of text messages, enter details about themselves into the system. These include location, skills, career interests, and level of education. Whenever the job seeker is looking for a job, he/she can text "match me" to Souktel to receive an instant list of jobs that matches the resume that is already stored in the Souktel system. The job listings include phone numbers so that the job seeker can call potential employers to set up an interview.

Korenblum said that at least 2,000 people use the service each month and the service has about 8,000 total users. In the past year, JobMatch has connected about 500 people with jobs. Users tend to be between the ages of 18 and 25, and the system recently expanded to include internships and volunteer opportunities. In June, about 170 people found jobs using Souktel, but the service’s success is partially reliant on the economy.

Earlier this year, Souktel launched services in the Iraq and Somaliland. In the future, Korenblum hopes that Souktel continues to grow, and could be used to connect people not only with jobs, but with educational programs or health and social services. "SMS is pervasive,” he said. “It is also by far the most cost-effective way for people to get the information they need." He also hopes to continue to share Souktel’s platform. “We've been struggling with it for three years now, and we've arrived at something that works,” he said. “We want to save someone else time in trying to develop it, so they have something that is useful for them.”

SMS for Emergency Services

I blogged few months back about SMS for emergency services in USA now the same is being tried in UK.

Ofcom is trialling a new system to let deaf people access 999 services using text messaging.

The system lets users who can’t speak send a text message to emergency services. Their text is received by 999 assistants and read out to fire, police or other emergency service. A reply is also sent back via SMS.

The trial kicked off earlier this month, with Ofcom asking people to register to test the service. As the trial will use actual emergency messages, it needs enough people to register to get a good feel for how the system is working as most won’t actually have cause to use it.

To register, text “register” to 999; anyone not registered will not be able to use the service.
Ofcom noted that users shouldn’t assume their message has been received until they’ve received a reply, and that anyone sending hoax messages will be prosecuted.


If the trial goes well, the texting system could be in place as early as next year, Ofcom said. It’s being supported by the major telecoms companies, as well as emergency services and the Royal National Institute for Deaf People (RNID).

Network Interfaces for Applications using Parlay and OneAPI

Here is an old posting on Parlay/OSA that might be useful to put things in context.

An important development related to service evolution is operators making interfaces available to external applications for information and control. Two widely deployed capabilities today include location queries and short message service. With location, mobile devices or external applications (e.g., applications operating on computers outside of the network) can query the location of a user, subject to privacy restrictions. This can significantly enhance many applications including navigation, supplying location of nearby destinations (e.g., restaurants, stores), location of friends for social networking, and worker dispatch. With SMS, external applications can send user requested content such as flight updates.

Until now, the interfaces for such functions have either been proprietary, or specific to that function. However, there are now interfaces that span multiple functions using a consistent set of programming methods. One set is the Parlay X Web Services, a set of functions specified through a joint project of the Parlay Group, the European Telecommunications Standards Institute (ETSI) and 3GPP. The Open Mobile Alliance (OMA) now manages the Parlay X specifications. Parlay X Web Services include support for location and SMS, as well as many other functions with which developers will be able to build innovative applications.

Table 4 (above) summarizes the available Parlay X specifications. Operators are beginning to selectively deploy these functions. The advantage of this approach is that developers can build applications that are compatible with multiple operator networks.

A related project is GSMA OneAPI, a GSM Association project to also define network interfaces, but that prioritizes implementation based on expected market demand. OneAPI defines a simplified Web service for most functions that is essentially a subset of the related Parlay X Web service. It also defines a REST (Representational State Transfer) interface for most functions as an alternative to using the Web service. RESTful interfaces are simpler for developers to work with and experiment with than Web services.

Regardless of whether operators deploy with Parlay X or OneAPI, these are mainstream interfaces that will open wireless networks to thousands of Internet programmers who will be able to build applications that leverage the latent information and capabilities of wireless networks.

Opera Mini: Better and More Popular


Opera Mini has been downloaded more than 25 million times from the GetJar mobile application store, the companies said.

The mobile browser is one of the most popular in the world because it is available on a variety of devices including Java, Android, BlackBerry, Windows Mobile, and other handsets. It is also able to run on relatively low-end hardware because it uses server-side compression technology to minimize the processing and bandwidth requirements.

Opera is bringing multipage browsing to its popular Mini browser, with a beta rolling out today. Mini 5.0 also gets a slick visual makeover, and touch support on devices that accept touch input.

Underneath it's the familiar Opera 4 Mini engine with a few tweaks, and existing users will be relieved that key shortcuts have been retained. But the proliferating screens of settings, bookmarks etc are now accessible by a pulldown menu. The address bar and search bar are integrated into the page view, almost exactly in the manner of iPhone Safari. Usually the ideas in the browser flow the other way.

Opera Mini 5, out now in beta, features a sleek new design to give the browser a more intuitive look and feel, the firm said. Also included is tabbed browsing, enabling users to browse several sites simultaneously, and support for touch screen as well as keypad-based browsing.

A Password Manager function acts as a "virtual memory bank" to store all a user's passwords for email, social networking and other online accounts, according to Opera.

Finally, Opera Mini 5 features Speed Dial, providing users with pre-selected web sites on loading the browser to jump straight to the content they want.

"The idea of navigating the vastness of the web from such a small screen can be a daunting leap, which is why we have long committed to make the browsing experience you are familiar with from your PC, easy to do on your mobile phone," said Jon von Tetzchner, chief executive of Opera Software.

"With new sleek navigation buttons, tabbed browsing and Speed Dial bookmarks, you are never more than a click away from where you want to go on the web."

Farmers worldwide being helped by Mobile Phones Technology


Airtel has entered into a strategic tie-up with IFFCO (Indian Farmers Fertilisers Cooperative) for providing agriculture and allied information to farmers through mobile phones. The facility was formally launched by the Chief Operating Officer (Andhra Pradesh) of Bharti Airtel Limited, Rajnish Kaul, at a function at Anakapalle town, about 40 km from here on Tuesday.

Addressing a media conference on the occasion, he said that the unique facility would benefit over 10 lakh IFFCO society members of rural Andhra Pradesh by giving them access to vital information. The farmer members would be given five free voice messages on farming techniques, weather forecasts, dairy farming, animal husbandry, fertilizer availability and rural health initiatives.

Mr. Kaul said the farmers could also call a dedicated free helpline to get answers from a qualified veterinarian to their specific queries regarding the health of their animals. He said that SIM cards would be provided at subsidised rates and lifetime activation would be done for a mere Rs.47. Calls between the members would be charged at 50 paise a minute. The SIMs would be compatible with any mobile handsets and farmers could buy the handsets of their choice depending on their purchasing power. He said the facility was launched about six months ago in various districts of the State and there were already 65,000 connections.

Question Box provides a service in India and Uganda. In India, phone boxes are installed in slums and villages that connect users to operators that will answer questions. In Uganda, users can call in from any mobile phone and ask their questions. The operators have access to a repository of previously asked questions (and their answers), and they can also occasionally consult the Internet. A special search engine and database were also built specifically for the project.

Another initiative, Avaaj Otalo, provides an audio community forum for farmers in rural Gujarat, India. Working with an organization that produced a popular radio program, Otalo provides a call-in number where farmers can exchange questions and answers. Users are also able to listen to archives of the radio program.

These projects differ in that Question Box avoids having to process users' questions by adding a human listener in the loop; Avaaj Otalo avoids processing by organizing their collection of audio prompts with into a menu. Both programs, however, have yet to deal with the problem of cost because they subsidize the service for users. Otalo operates with a toll-free number and Question Box provides the phones to call from in India. In Uganda, Grameen Community Knowledge Workers provides the mobile phones.

It's easy to see why the fishermen of the southern Indian state of Kerala captured the attention of a Harvard economist when they began using mobile phones a few years ago to track prices in the markets where they sold their catch of the day. Observing how these devices can be used to promote economic growth, Robert Jensen wrote in a 2007 paper titled, "The Visible Hand(set): Mobile Phones and Market Performance in South Indian Fisheries -- The Micro and Mackerel Economics of Information," that "before mobile phones, deciding which [market] would offer the best price was sheer guesswork." With mobile phones, however, suddenly it became an information-based decision. What's more, noted Jensen (who is currently at Brown University in Rhode Island), "it's not a zero-sum trade-off." The fishermen's customers benefitted from lower prices and greater choice, and there was less waste since the fishermen could easily identify the villages that would have the greatest demand for their fish each day.

Now Jensen's "visible handset" is reaching further into rural India. Following a nationwide launch this summer of Nokia Life Tools (NLT), India's farmers can use their mobile phones to access tailored information to help them grow, harvest and sell their crops and manage their livestock. "There is no reason why farmers should not be as successful as fishermen," says Ravi Bapna, associate professor of information systems at the Carlson School of Management in Minnesota and executive director of the Centre for Information Technology and the Networked Economy at Hyderabad-based Indian School of Business (ISB).

Consider Ravindra Shinde, a farmer in Magardhokada, a village in the Nagpur district of Maharashtra. When he recently harvested 125 quintal (a quintal is 100 kilograms) of soybeans and was about to take the crop to market, the price was $32 a quintal. But then he received a message on his handset that soybean production in the U.S. and Argentina had fallen, so he held back and later sold his crop for $48 a quintal.

IN the early 1990s, I was engaged in an empirical research work relating to the nexus between mobile phone and poverty in rural Bangladesh. However, friends used to tease me and raise their eyebrows on hearing about the project and my interest at that time. This was to be expected in the early 1990s when, not to speak of the poor, even the "solvent" could not afford to have a mobile set. It was treated as a "luxury" item, only to be monopolised by the moneyed people.

My research findings on village pay phones of the Grameen Bank at that time -- and as published in international journals in subsequent years -- clearly showed that mobile phones could help the poor escape "rural penalty" (a la H. Hudson), defined as poverty mainly due to distance, poor connectivity and asymmetric information. However, as of today, about 40 percent of the rural households in Bangladesh are reported to have access to mobile phones and roughly one-fourth of the users are poor. Rickshaw pullers, fishermen, traders all use it to minimise information asymmetry and quicken communication between two points.

About a decade later, I was invited to comment on two research papers showing the impacts of mobile phones on farmers and traders in Africa.

The first paper was by Megumi Muto and Takashi Yamano, both representing JICA and Foundation for Advanced Studies on International Development (FASID). They drew upon panel data of rural Uganda where banana producers could reduce marketing costs and raise income with expansion of mobile phone coverage. The message is that the expansion of mobile networks increased market participation and sales of the perishable product, banana. More importantly, small producers and farmers in remote areas gained the most.

As information flow increases due to the expanded mobile phone coverage, the cost of crop marketing is expected to decrease, particularly in remote areas where potential marketing gains from the increased information flow is large. We indeed find that the network expansion has a larger impact in market participation in areas farther away from the district centers than in closer areas.

The second paper was presented by Jenny C. Aker of the University of California, Berkeley, on the impact of mobile phones on price dispersion of grains in Niger. Using a sequential searching model, the researcher observed that cell phones increased traders' reservation sales price and the number of markets over which they searched. This reduces price dispersion across markets. To be specific, grain price dispersion reduced by 6-7 percent and reduced intra-annual price variation by 10 percent.

What is important, and as revealed in both papers, is that every farmer need not possess a set. It could be the community, producers' organisations and others from where the price information could spread, either as a "public good" or as a "private good." A participant from the audience in that seminar informed us that in his village in Africa, a mobile phone is hung from the branch of a tree and interested persons could use it on payment of a fee. Second, even with access to mobile phones, full gains might not be reaped as farmers might need more information. The role of public authority and media in this respect is very important. Again, producers' organisations could form an information forum of their own to be more effective at bargaining than individual initiatives.

Mobile Phones to replace Alarm Clocks


More than half of Brits are now using their mobile phones as alarm clocks, an alarming development for clock traditionalists.

They fear it could mean the end for dedicated alarm clocks, which have sat dutifully on our bedside tables for 150 years.

A survey of 1,500 people found that 52% had used their mobile as an alarm clock with 21% using it to get them up in the morning each day. Of course it also means you are likely to be woken up in the early hours when your do-it-all phone starts beeping because you've received an email about viagra.

A spokesperson for Rightmobilephone.co.uk - who commissioned the study - said: "The mobile phone now plays a larger more important role in our lives. "Handsets now provide us a wealth of information on the go, schedule our social occasions and as we found for many simply ensure we get out of bed each morning.



"The mobile phone is no longer for communication only, our independent handset reviews show signs of this with consumers often praising or berating the handsets camera or music quality, discounting its ability to make calls or text."

Mobile Search in Future...


Interesting Blog from Mohit Agrawal on the future of Mobile search.

How is Mobile Search different?

The fundamental difference between the mobile search and PC search is the access device. The screen size of the mobile phone is a constraint and hence the internet search results need to be modified. Even the input keyboard is different and the search string could be shorter which means the search result has to be intuitive.

The second difference is in the usage pattern of mobile. Unlike PC, the mobile phone is a ubiquitous device and people normally search for “at the moment” kind of thing. This means they search for nearest restaurant, retail points, service centers or mobile content. Their need is immediate and the patience or tolerance is low. They are looking for relevant results that are actionable like they need a taxi that can reach them fast and they should be able to book the taxi using their mobile phone. This means that the result needs to be location aware and should also give the phone number of the taxi company.

Thirdly, the consumer expectations changes with the time of day for the search results e.g. an afternoon search for restaurants means that the results should be about restaurants amenable to business meetings whereas, in the evening the same search should retrieve fun places like pubs or lively music restaurants.

Lastly, the difference is in the frequency of search and the number of attempts for each search.

On PC, a surfer changes his search string multiple times before he gets the right results while on a mobile, nobody is likely to change the search string more than a couple of times. Also, people search at least 4-5 different things on PC everyday but a typical mobile internet user searches something only once in 4-5 days.

There are quite a few videos which he uses to explain the point and they are interesting watch. I strongly recommend to go and have a look at the blog.

Another thing that will become important is the advertisements within the search. If I am looking for a day out on the weekend and if I get another option while searching for my destination then I may be tempted. While out and about, search for restaurants or the nearest MacD may may give some tempting offers about from other restaurants.

I can see lots of potential in mobile search and I am sure that there are companies that are working towards them. Its just matter of time before another new player like YouTube, Facebook or Skype may become leader of this domain.
