SMS Rocks! Long distance shoulder amputation by text

We have heard of dumping and divorce through SMS, betting through SMS but none can beat this one. A surgeon carried out an operation in Democratic Republic of Congo by following instructions received over SMS.

A British surgeon volunteering in the Democratic Republic of Congo saved the life of a teenage boy by amputating his shoulder using instructions texted by a colleague in London.

David Nott, 52, a general and vascular surgeon at Chelsea and Westminster hospital, was working with the charity Médecins sans Frontières (MSF) in the town of Rutshuru when he came across the badly injured 16-year-old in October.

The teenager's left arm had been so badly damaged - either in an accident or as a result of the fighting between Congolese and rebel troops - that it had already had to be amputated. But the flesh and bone that remained had become badly infected and gangrenous.

"He was dying" said Nott. "He had about two or three days to live."

The doctor realised the boy's best chance of survival was a forequarter amputation which requires the surgeon to remove the collar bone and shoulder blade. The only problem was that it was an operation Nott had never performed. But he remembered that one of his colleagues at home had carried out the procedure.

"I texted him and he texted back step-by-step instructions," he said.

"Even then I had to think long and hard about whether it was right to leave a young boy with only one arm in the middle of this fighting.

"But in the end he would have died without it, so I took a deep breath and followed the instructions to the letter."

Such an operation, if performed in the UK, would require careful planning with every sort of modern medical product on hand if things went wrong.

But in Congo Nott had just one pint of blood and an elementary operating theatre.

Despite the basic conditions, the operation was a success and the teenager made a full recovery.

This news could not have come at a better time because the inventor of SMS, Matti Makkonen, received this year's Economist Innovation Award for Computing and Telecommunications.

If I remember my stats correctly, there are 3Billion+ users or SMS worldwide with 1Billion+ SMS exchanged daily and its nearly 20 years since SMS has been launched.

Nokia admits defeat in Japan

Finnish mobile phone giant Nokia has said it will stop selling its handsets in Japan after struggling to grow its market share in the country.

Nokia said it would continue selling its luxury Vertu brand in Japan, and would dedicate its Japanese business to research purposes.

Nokia has nearly 40% of the global market for mobile phones, but it reportedly managed to take only 0.3% of Japan's market last year.

Samsung and LG have also faced problems in Japan - a market dominated by sophisticated domestic phones.

According to research firm IDC Japan, foreign companies account for only 5% of the Japanese market, which is dominated by local firms selling phones with features such as TV broadcasting and electronic payment functions.

The Nokia-owned luxury brand Vertu was created in 1998 and focuses on one-off specialist phones costing from 3,500 euros to more than 100,000 euros.

Nokia to power Smarter Homes

Nokia Home Control Center - My home is where my phone is

Nokia Home Control Center is a solution based on an open Linux based platform enabling the home owner to build a technology-neutral smart home that can be controlled with a mobile phone, using a unified user interface. Nokia Home Control Center supports the most common smart home technologies, including Z-Wave as well as enabling the incorporation for proprietary technologies. Thus, it allows third parties to develop their own solutions and services on top of the platform, expanding the system to support new services and smart home technologies.

Building blocks for an intelligent house are readily available in the market. Putting it all together is, however, like trying to build a house from blocks that do not fit with each other. There are smart refrigerators, energy-saving washing machines, heating systems that can adjust the room temperature with one-celcius-accuracy, security systems with touchpanels, low-energy walls, programmable thermostats, self-adjusting curtains, configurable set-top boxes, self-operating yard lights and much more. The problem is all these systems are separate and you end up having a dozen remote controllers and miles of cables in the living room.

Until now, solutions to home automation challenges have been sought through the development of better sensor networks. Although they are, of course, very important parts of new smart home solutions, no single sensor network technology can solve the challenges in this field. Z-Wave, ZigBee, and KNX are all attempts to define a common command language for home networks. So far, there has not been a clear winner in the battle for the de facto standard of home networks. Hence, it can be assumed that a future home will use several different technologies.

The Nokia Home Control Center acts as a dictionary that translates different technological languages so that they can be presented in a unified user interface. Furthermore, the platform enables grouping different physical devices, even from different manufacturers, to be presented for the user in an easy-to-understand way.

The whole Nokia solution consists of four main components:

1. The heart of the solution is the Nokia Home Control Center which is built on top of standard gateway architecture.
2. Two most important control nodes are the mobile phone and web browser.
3. The back-end server architecture ensures a seamless and secure link between a mobile device and the home gateway and also makes possible updating and upgrading software easily.
4. The partner devices. In addition to the components that Nokia is providing, the value for the end customer comes from the integration of different third party devices and systems under the control of one user interface.

It will be possible for example to monitor and control electricity usage, to swich devices on and off, and monitor different objects, such as temperature, camera, and motion. On one hand, Nokia Home Control Center can be used as WLAN gateway. On the other hand, the platform covers everything from a basic security solution to a more sophisticated heating control system. Users are free to build a solution that fits to their needs and expand it when ever they want.

Mobility is becoming increasingly important in home environments, as wireless technologies for smart home solutions are emerging. As structure wiring is no longer required, these are no longer niche market products meant for new houses. Wireless broadband has become main stream and multimedia consumption over home networks is increasing. From many studies we know that moving from a multimedia network to a smart home network is a much smaller step than building a wired smart home from the scratch. Finally, the last barrier of high equipment prices is breaking down as the technology becomes more and more common.

Nokia 'Home Control Center' features and technical data can be seen here.

The following is additional info from the press release:

Nokia today also announced a partnership with one of Europe's biggest energy companies, RWE. The co-operation aims at developing a comprehensive solution for managing energy consumption and CO2 footage at home. This cooperation combines RWE's energy competence with Nokia's technological know-how.

With this in mind, the first joint solution from Nokia and RWE on late 2009 will focus on home heating management. The product consists of a central control unit together with remote-controlled thermostats for the actual radiator. The user interface will be the PC and the mobile phone. In addition, a separate display will be available. RWE is also planning special offers combining these devices with new energy supply contracts. In a second step, Nokia and RWE are planning additional services in connection with smart meters beyond 2009. These services will provide consumers with real-time information about their energy consumption and allow them to control their energy bill remotely.

"We are delighted to have secured a world-leading technology partner in Nokia for our range of smart home energy products. Our aim is to offer innovative and affordable energy-efficient solutions for every household that are simple and convenient to operate", said Carolin Reichert, Head of New Business at RWE.

Nokia Home Control Center will be part of Nokia's home offering. The solution will be demonstrated at the Nokia World event in Barcelona, Spain, on December 2-3, 2008 and is expected to become commercially available by the end of 2009.

Is Urgency for LTE growing?

Few weeks ago in response to Zahid’s blog I wrote that LTE may not be that far away as might be thinking.

In this blog I would like to carry this thought forward. With more and more giants moving into LTE camp as compared to WiMax there is a sense that LTE will soon pick up. Recently I have been sensing that thee is some urgency out there in regards to LTE development. Vendors and operators are pushing to the extent to get the technology out as soon as possible.

As I mentioned some time ago that I am really a big fan of HSPA+ and I once again say that till LTE arrives, HSPA+ can serve the purpose up to an extent.

As we already know that T-Mobile recently tested LTE and this really gave a push to the technology. There are lots of 3G operators now who share T-Mobile’s LTE aspirations although reaching to these LTE or 4G goal will not be straight forward. Lot of urgency for LTE also depends on what the operators do with HSPA+. Some of the operators might go for HSPA+ and hence wait longer before deploying LTE.

It’s quite interesting to see that operators such as T-Mobile are going for LTE whereas some operators currently staying away from LTE and hence going to launch HSPA+. Evidently LTE as it still a long way away from mass market maturity hence it’s going to be difficult for some operators to stick to its guns for LTE. I guess this also is one of the major factors contributing towards the urgency for LTE.

Currently the three big operators pushing LTE development are China Mobile, NTT DoCoMo and Verizon wireless. T-Mobile believes it is every bit as aggressive as those three operators and should be included in that list. The evidence of this is the urgency shown by T-Mobile when it tested LTE recently.

T-Mobile believes that LTE is suited in the long run, i.e. till 2020, to be the technology that you can consolidate all technologies onto -- GSM and UMTS.

Another operator showing urgency toward LTE is the world's largest mobile operator in terms of subscribers, China Mobile. China mobile plans to begin testing LTE soon where only the lack of chipsets are holding back its plans at the moment. Many telecom experts believe China's operators will essentially leapfrog 3G as the government continually delays tenders and opt for a 4G deployment like LTE.

At the same time as I mentioned some of the operators might decide not to get sucked into HSPA+ and rather push for LTE. This urgency for LTE is certainly demonstrated by T-Mobile once again when it announced it will not deploy HSPA+. The operator has indicated that to boost its mobile broadband throughput it will instead invest in LTE thus stepping up the pressure on equipment vendors. However T-Mobile might deploy HSPA as long as no hardware upgrade is required.

The above developments is allowing some to accuse T-Mobile of attempting to force equipment vendors to place greater emphasis on the development of LTE as against further refining HSPA+. Given that China Mobile, DoCoMo and Verizon Wireless have each made aggressive statements regarding their intent to push forward with LTE, then those interested in such plots have more to go on.

However, there is a question as to whether these operators, including T-Mobile, can wait for LTE, especially given the marketing hype around mobile broadband offers.

There is no denying that the above mentioned operators are aware of this situation and hence I guess this is main reason why they are showing immense urgency towards LTE.

Femtocells as the starting point - more info

Informa has recently come up with a report titled "Opportunities for femtocells in the mobile broadband ecosystem: the economic case for LTE and 3G+". I found the following very relevant to this topic that I have blogged earlier about:

One idea is to use LTE initially as an access point rather than a full standalone network, which would bypass all the difficulties and delays that may happen in developing the core network for this technology. Here femtocells, picocells or GAN dual mode solutions could help operators to achieve this goal. As well as the time to market advantage, operators will also have a good opportunity to test LTE access networks and their business case for it before engaging in any wide scale network rollouts. This will obviously help them to minimize risks while giving them enough time to get their networks more stable and ready for the challenge.

Deploying LTE through femtocells is now an industry accepted solution as mobile operators can incrementally add capacity to their networks where it is most needed. This is expected to be in the home environment where 60% of communication is expected to take place during 2013. Instead of performing ‘forklift’ upgrades for their macrocell networks, mobile operators can test the LTE business case by initially launching LTE femtocell networks. Overall capex is expected to be much less than for a macrocell network – but on the other hand, LTE femtocells will only create localized coverage and capacity hotspots for a limited group of end users.

Several chipset and hardware platform manufacturers have launched products for LTE femtocells, including Picochip and Agilent. The upcoming 3GPP femtocell standard is expected to provide compatibility for LTE femtocells and mobile operators are expected to announce their LTE strategies in 2009. Informa Telecoms & Media expects that the majority of mobile operators – especially those that have invested heavily in 3G – will incorporate femtocells in their LTE strategies either for business case validation or for selective, incremental capacity upgrades for their mobile networks.

SDR: Today and Future

I also got an opportunity to attend the SDR briefing in LTE World Summit. There were many interesting presentations including one titled "SDR in Mobile Devices" by Thierry Dubois, SDR Market Analyst, IMEC, Belgium. Infact last year I blogged about SDR from Imec presentation as well. The following is an extract from Thierry's presentation:

The key benefits of SDR are as follows:

• Reducing the Bill Of Materials (BOM)
• Lower development costs
• Facilitate better reuse of intellectual property (IPR)
• Possibility to upgrade products already in the field
• Enabler of the Cognitive Radio vision

There are three main areas where SDR's are required but some problems exist as can be seen from the diagram above.

• Flexibility is the key for baseband. Some of the common signal processing blocks may not be reusable. This means that though some protocols can easily be defined for a particular baseband, others may not be possible for that baseband. Good progress is still being made though on this front.
• Reconfigurable RF is some way away, further down the road.
• The biggest challenge is the antenna interface for which no proper solution exists. Some solutions being worked on right now include MEMS based solution, Carbon nanotubes, Special ceramic materials, etc.

The next step after SDR is cognitive radio (CR). The main advantage for using CR would be because spectrum is over-allocated but under-utilised. There are lots of white spaces in the spectrum that could be utilised by devices intelligently of their own.

Cognitive Radios are defines as: A radio that can autonomously change its parameters based on interaction with, and possibly learning of, the environment in which it operates. Through appropriate radio resource management, such a cognitive radio should make flexible and efficient use of network/spectrum resources.

CR would consist of Intelligent Sensing hardware and Intelligent Sensing Algorithms. There are two types of CR being considered:

• Opportunistic Radio: A radio that co-exists with other systems using the same spectrum. E.g., White Space Devices
• Smart Reconfigurable Radio Systems: A radio that makes flexible and efficient use of network/spectrum resources across heterogeneous environments. Seamlessly roaming possible on different networks, countries, frequencies, etc. It requires true paradigm shift i.e., spectrum liberalization

An Introductory paper on SDR is available on Bitwave Semiconuctor website.

Femtocells as the starting point

I blogged earlier about 'LTE Femtocell Layer as starting point'. During my visit to the LTE world summit, I didnt find (m)any takers for the idea initially. Then in his presentation, Prof. Simon Saunders, Chairman of Femto Forum, seemed to encourage the idea. As FemtoForum is technology neutral, he started with the case for WiMAX Femtocells. He quoted a VP from Comcast saying that Femtocells are "absolutely key to WiMAX" and he envisioned future services and packages that would encourage customers to use their WiMAX femtocells and stay on Comcast’s network.

Then he threw the following slide to the operators saying that introducing LTE network via Femtocell could be a way to roll out the LTE network.

In Release 8, HSPA based Femtocells will be standardised and Release 9 (De. 2009) will deliver LTE standards-based femtocells. Some operators are in hurry to roll out their LTE networks next year, since LTE home eNodeB's wont be standardised in time for them, maybe we will see LTE Femtocells as intial offering by some operators by mid-2010.

LTE: 3G or 4G?

Continuing the discussion from LTE World Summit:

Adrian Scrase, Chief technical officer, 3GPP, France threw light on the topic which I have mentioned many times in my blog. I have always maintained that LTE can be called 3.9G but media and some other presenters have always been referring to it as 4G. Here is a slide from his presentation on his topic.
I think now when LTE-Advanced and IMT-Advanced comes, it will no longer be referred to as 4G/5G/6G. Someone will have to come up with some clever new term :)

“Your Wireless Future” at “Tomorrow’s Wireless World”

This one is from Chetan Sharma's blog (via Forox). The following is an extract from his blog:

Earlier this week, I had the distinct honor of moderating a panel of some of the most eminent senior wireless research scientists and CEOs of wireless companies from Finland where we explored the future of the wireless landscape from user interface to reduction in carbon footprint to privacy and security issues and much more.

Many people might not be aware but the City of Oulu in the central part of Finland is a leading epicenter of wireless activities with many major industry players setting up shops for doing R&D work. In fact, it is quite likely that one of the companies out of Oulu has had an impact in some way on the mobile phone you have in your pocket (and we are not including Nokia).

The topic of our panel was “Your Wireless Future” – a broad topic that is always difficult to cover in 60 minutes or less.

I started by asking the panelists about what in their view have been some of the defining trends over the last 12 months. Summary of answers – iPhone; android; move towards full mobile browser; browser will reduce fragmentation and more innovation will happen on this front; with the rise of smartphones, security and privacy have become an issue,

Some other salient points (read issues and opportunities) from the discussion:

• It is forecasted (by WWWRF) that in another 10 years, we will have 1000 radios per every subscriber. That would translate into few trillion nodes around us. The level of complexity and carbon footprint will be enormous. One has to figure out a way to address both.
• City of Oulu has first of a kind experiment with NFC where the technology has been embedded in day-to-day life from home, school, train station, restaurant, probably every object in the city. Pretty interesting experiment that will lead to interesting use cases and technology implementations.
• There are so many protocols being integrated into the device that hackers are targeting not only the data but the protocol weaknesses to gain access. IT finally starting to address smartphone issue in their networks.
• The role of Cognitive radio and SDRs will gain prominence as more access technologies get introduced.
• In a ubiquitous environment with finite spectrum, “sensing” technologies will have a great role in optimization. Sense and do the best for the consumer, the device, and the network. Hyper connectivity will become the norm.
• In addition to touch, gesture and face recognition will add to a better multimodal experience.
• Mobile payments is coming and going to make a big impact. We have to of course sort out the business models.
• 3Cs of mobile – convergence, context, and community (Nokia’s Mantra).
• The very business of R&D has changed significantly with corporations choosing to outsource R&D and the cycle of concept to market launch has shrunk from 6 years or more to 12-18 months.
• More innovation will come from integration of existing technologies rather than some big breakthrough.
• Demand for bandwidth will keep growing.
• Significant opportunities in medicine, enterprise, and other industry verticals.
• In developing countries, while consumers are willing to pay for expensive devices, they don’t have any appetite for expensive service plans.

Some discussion points from Craig’s (Dr. Craig Barrett, Chairman of Intel Corporation) and our Q&A session:

• World will go to free MIPS and free baud (computing and communications). What happens then?
• Moore’s law is good for another 15 years based on 5 generation of future chipsets that they have in the labs. And it will probably keep going after that.
• Awareness of context really important.
• Many types of devices will proliferate including MIDs, education devices, some designed specifically for special purpose (medical monitors) and geographies (emerging markets).
• Global challenges are education, health, computing, and communication.
• In the developed world, wireless technology can help reduce the cost which is increasing at the rate of $200B/year and in the developing world, technology can help provide access to health care.
• Convenience and access trumps security concerns.
• Areas of opportunities – Telemedicine, education, economic development, governance, energy and environment.
• This is Craig’s 11th recession. Principle to tackle has been the same every time. You cannot save your way out of recession. You can only innovate out of a recession. Intel R&D budgets will remain the same.
• Innovation is key to surviving and competing in the global economy, now more so than ever.
• The fact that so much can be done in these tiny piece of electronics is just amazing and the drive to do better and more using technology keeps him going, keeps him inspired.

I am looking forward to an interesting future ;)

Phones can be unlocked by GeoSim

We all have used different phones over the period of time while on contract with a certain operator. The tricky situation comes when we move onto different operator and would sometime like to use the old phone. The way to crack this is quitely simpy unlock the phone and off it goes on any network.

GeoSIM, an international SIM card supplier, now says that it has introduced the “SIM PIG”, a SIM-like chip that bypasses the network lock on mobile phones, thus enabling any SIM card from any network to be used in a locked handset.

I honestly do not know whether this is good or bad, but simply for my own personal reason it’s good. Recently I moved from one operator to another and decided to go pay as you go. Hence I wanted to use my old phone on the new service provider but couldn’t do so until I got my phone unlocked.

SIM PIG claims to be able to unlock iPhone, Windows Mobile, HTC, Nokia, Sony Ericsson, Blackberry and many more 3G handsets. It is inserted with the SIM card into the handsets SIM card slot. The PIG then dynamically bypasses the network lock on the mobile phone. The company says it does not affect any of the handset functionality and all features are maintained, nor it does not invalidate any warranty on the handset. Once SIM PIG is removed, the handset reverts back to its locked condition.

Using the SIM PIG does not require any technical knowledge and is quick and simple to insert. As the name suggests, SIM PIG SIMply PIGgy backs on to the SIM card when it is inserted to the handset.
So how does GeoSim is able to do this business of unlocking the phone or by passing the lock?
GeoSIM routes your dialling instruction away from the local operator and sends your call to the GeoSIM “Hub”. A few seconds after you make your call, your mobile phone will ring. You answer the “callback” and you will be connected to the person you wish to talk to.
In summary:

• Dial the number you want to call.


• A few seconds after you dial, your handset will ring. Answer the “callback” from the GeoSIM Hub.


• You will then get connected to the number you are calling.

Hmmm very strange… I am really dying to know whether some body uses this method.
Do GeoSIM and SIM PIG work in the United States?
Are they fully “legal” here in UK or Europe? I don’t know…
