Mobile Screensaver helps catch a burglar

This story can probably be nominated for the most stupid awards.

A bungling burglar was caught out after he left his mobile phone - with a picture of himself on the screen - in a house he had broken into, police said.

Richard Hannah was jailed for six years today after he was found guilty of burglary by a jury at Nottingham crown court.

Hannah, 30, was confronted by the owner of a house in Mansfield Woodhouse, Nottinghamshire, after he broke in at about 4am on 15 September last year.

After a scuffle between the pair, Hannah, from Poplar Street, Mansfield Woodhouse, left his mobile phone, with a screensaver photo of himself, at the house.

Hannah was found guilty today of burglary after a three-day trial, despite claiming the phone had been stolen and left by someone else.

He was jailed for six years under the government's "three strikes and you're out" crackdown, Nottinghamshire police said.

Future Phones will be able to understand your thoughts

Honda is working on a technology for Robots in Japan where they can understand the owners thoughts. Right now only four commands can be understood but the success rate is 90%. If this technology becomes successful it can probably be applied to phones as well.

I remember reading (cant find link, sorry) that NTT DoCoMo has already developed a prototype of phone in which you can speak without any sound and the person at the other end wont even notice. He will hear normal voice.

NTT DoCoMo launched Motion sensing phones couple of years back and the main idea was that the user can control things by motion of their hands. I havent dug into details but I can visualise myself in future working on my laptop and just by waving my hand ask my mobile to start composing a text message. I would be able to dictate the message and just with another wave of my hand, the message will be sent.

Japan has always been the leader of these kinds of technologies and companies out there are working hard innovating new technology. NTT DoCoMo (again) showed off last year a technology where the volume can be controlled just by rolling the eyes. At the moment all these things involve some kind of human attachment which makes them impractical for the time being. In future hopefully there will be better alternatives and more reliable technologies like these.

Anyway, we wont see any of the above technologies anytime soon. There is a funny video on Youtube that you will like about these future technologies that is available below:

HSPA based Laptop Enabler/Disabler

Ericsson (NASDAQ:ERIC) today unveiled its most advanced mobile broadband module, uniquely designed with innovative features to provide a richer and cost-effective internet experience for all. The next-generation module marks the latest milestone for Ericsson, furthering the company's vision of an all-connected world.

Ericsson's F3607gw mobile-broadband module for HSPA/GPRS/EDGE networks, to be released in June, will provide enhanced functionality and convenience through its innovative features, reduced power consumption, prolonged battery life and an increased level of integration, reducing the number of necessary components and therefore cost. The new module will also provide built-in mobile broadband support for Microsoft Windows 7.

Mats Norin, Vice President of Ericsson Mobile Broadband Modules, says: "The combination of leading technology and innovative design in the next-generation module is key to delivering a superior user experience at an affordable price. This module release confirms Ericsson's commitment to making the benefits of connectivity available to everyone."

An important facet of the F3607gw is the unique wake-on wireless feature. By remaining connected while a notebook or netbook is in sleep mode, the module's wake-on wireless feature enables users to remotely wake up the device. This innovative technology will allow a new set of applications to be built into the computer to further enhance security and instant-on functionalities, such as the ability to disable the computer in case of theft, or instant distribution of important messages and security updates.

Operators can also combine the wake-on wireless feature and embedded GPS functionality to create a range of differentiating services for consumers and the enterprise market, including remote manageability, security updates, asset protection and tracking and geo-fencing. The module can also be used for content push services, such as podcasts, public warnings, traffic updates and database updates.

Specifically, the wake-on wireless feature supports security solutions based on Intel's Anti-Theft PC Protection Technology. An anti-theft management service in the network can send a message via SMS to the mobile-broadband module inside the notebook, which securely transfers the message to Intel's Anti-Theft function inside the processor platform. This takes appropriate actions, such as completely locking the computer and making it unusable. When the notebook is located and recovered, an unlock message can be sent to the notebook that makes the data accessible again.

Anritsu's LTE Tester MD8430A is a winner

Anritsu Company announces its MD8430A Signalling Tester was the only test instrument to win a prestigious CTIA Emerging Technology (E-Tech) Award, announced during the International CTIA WIRELESSS® 2009 show in Las Vegas.

“We are thrilled and honored to have won a CTIA E-Tech award because it signifies the best and brightest technologies in the wireless market. We would like to thank everyone who participated in the voting and supported the MD8430A,” said Wade Hulon, Vice President and General Manager of Anritsu Company, Americas Sales Region. “The MD8430A is being used by LTE chipset manufacturers to ensure the quality of their products, speed time to market, and reduce design and production test costs.”

Approximately 300 entries were received for this year’s E-Tech Awards. They were reviewed by a panel of 30 recognized members of the media, industry analysts and executives who selected finalists based on innovation, functionality, technological importance, implementation and overall “wow” factor. More than 40,000 wireless professionals voted on the finalists to determine the winners in 18 categories.

The MD8430A is a highly accurate cost-effective solution for manufacturers of LTE chipsets and mobile devices to evaluate their products and improve time to market. Developed in conjunction with leading chipset manufacturers, the MD8430A augments Anritsu’s broad 3GPP test suite, providing developers of wireless devices and systems with a single-source test solution company.

The MD8430A is designed with 4 RF units that enable 2x2 MIMO system handover tests in a simulated network environment. The base station simulator can conduct end-to-end testing at downlink speeds up to 150 Mbps and uplink speeds up to 50 Mbps. All critical 3GPP air-interface LTE protocol tests, including baseband coding/decoding processing tests; protocol sequence tests, such as position registration, origination, termination, handover, terminal and network disconnect tests; and application tests, are supported. Powerful L1/L2 cache analysis functions are provided as well.

Presentations on Mobile Apps

There are couple of interesting Mobile App related discussions in Forum Oxford recently, for anyone interested:

An interesting presentation on Application Stores and Mobile Social Media by Cedric Giorgi is available on SlideShare.

Another one titled, The App store and Future of Mobile Applications by William Volk is available on Slideshare as well.

William has also started an interesting discussion where he makes an interesting point:

In the case of the Android App Market, paid app sales are a fraction of what one would expect. The top paid apps have sold only a few 1000 copies, free apps have reached download numbers of over 250,000.

Why? Most users have not opted-in to Google Checkout, which is the billing system used.

Apple, of course, requires users to opt into iTunes, but iTunes already has widespread acceptance. 93% of iPhone users have purchased an app.

My understanding is that Google approached T-Mobile about this and the idea of adding carrier billing as an option was rejected.

So let me get this straight:
1. Apple cleverly cuts operators out of the app revenue stream.
2. Competing 'open' platform, Android appears.
3. Operators reject Google's offer to use their billing systems for app purchases.
4. Operators see no revenue from app sales on iTunes AND Android App Marketplace.
5. Android is a non-starter for app developers in business terms.
The question is, will users opt in for PayPal when the RIM App World turns on?

More than 1 Trillion messages were sent in 2008

CTIA -The Wireless Association® announced the findings of its semi-annual industry survey, which includes numerous positive metrics on the industry’s continued growth and popularity. In particular, wireless revenues showed impressive year-to year gains, as wireless data service revenues for the year 2008 rose to more than $32 billion. This represents a 39% increase over 2007, when data revenues totaled $23.2 billion. Wireless data revenues for 2008 amounted to nearly 22% of all wireless service revenues, and represent what consumers spend on non-voice services.

According to the survey, text messaging continues to be enormously popular, with more than one trillion text messages carried on carriers’ networks in 2008—breaking down to more than 3.5 billion messages per day. That’s almost triple the number from 2007, when 363 billion text messages were transmitted. Wireless subscribers are also sending more pictures and other multi-media messages with their mobile devices, with 15 billion MMS messages reported for 2008, up from 6 billion the year before.

Wireless subscribers are also sending more pictures and other multi-media messages with their mobile devices, with 15 billion MMS messages reported for 2008, up from 6 billion the year before.

As of December 2008, the industry survey recorded more than 270 million wireless users. This represents a year-over-year increase of nearly 15 million subscribers. The industry’s 12-month record for subscriber growth was reached in 2005, when 25.7 million new users came online.
Other highlights of the survey include: wireless customers using more than 2.2 trillion minutes in 2008, an increase of 100 billion minutes from 2007, and record-breaking six-month wireless service revenues of more than $75 billion with annual service revenues reaching $148 billion by year-end 2008.

The CTIA Semi-Annual Wireless Industry Survey results were released on 1st April 2009 at International CTIA WIRELESS 2009®. Billed as the most important global technology event of the year, with more than 1,200 exhibiting companies and around 40,000 attendees from 125 countries, it took place April 1st -3rd at the Las Vegas Convention Center in Las Vegas, Nevada.

According to another survey in Canada, relationships often blossom thanks to technology. Two in five (42%) of Canadians aged 18-34 would send a flirtatious text to hint they have a crush. Youth are also significantly more inclined to flirt with their crush using Facebook wall posts or gifts (35%) and instant messaging (32%). On the other hand, just over one in ten Canadians aged 55+ would use Facebook (15%) and instant messaging (12%).

Results also show Canadians are doing everything from flirting to breaking up, all using technology. Surprisingly, a full 10 per cent of Canadians would give someone the hint that their relationship is over by changing their Facebook status. When it comes to breaking up the old fashioned way, 35 per cent of Canadians would choose to break up with someone over the phone or in person and only 10 per cent would opt not to use technology to get this message across.

Orthogonality and non orthogonality

Multiple access (MA) is a basic function in wireless cellular systems. Generally speaking, MA techniques can be classified into orthogonal and non-orthogonal approaches. In orthogonal approaches, signals from different users are orthogonal to each other, i.e., their cross correlation is zero, which can be achieved by time division multiple-access (TDMA), frequency-division multiple-access (FDMA) and orthogonal-frequency division multiple-access (OFDMA). Non-orthogonal schemes allow non-zero cross correlation among the signals from different users, such as in random waveform code-division multiple-access (CDMA), trellis-coded multiple-access (TCMA) and interleave-division multiple-access (IDMA).

First and second generation cellular systems are dominated by orthogonal MA approaches. The main advantage of these approaches is the avoidance of intra-cell interference. However, careful cell planning is necessary in these systems to curtail cross-cell interference. In particular, sufficient distance must exist between re-used channels, resulting in reduced cellular spectral efficiency.

Non-orthogonal CDMA techniques have been adopted in second and third generation cellular systems (e.g. CDMA2000 and uplink WCDMA). Compared with its orthogonal counterparts, CDMA is more robust against fading and cross-cell interference, but is prone to intracell interference. Due to its spread-spectrum nature, CDMA is inconvenient for data services (e.g., wireless local area networks (WLANs) and 3GPP high speed uplink/downlink packet access (HSUPA/HSDPA) standard) that require high single-user rates.

Communication services can be classified into delay sensitive and insensitive ones. A typical example of a delay-insensitive service is email. Typical examples of delay-sensitive services include speech and video applications. For delay insensitive services, rate constraints are relatively relaxed for individual users and maximizing the throughput by orthogonal methods is a common strategy. The maximum throughput can be achieved by a one-user transmission policy, where only the user with the largest channel gain is allowed to transmit. This implies time domain orthogonality as adopted in many WLANs. For delay-sensitive services, on the other hand, each user must transmit a certain amount of information within a certain period and maximizing the throughput is no longer an appropriate strategy. Rate constraints must be considered in this case.

CDMA is the most well known non-orthogonal technique. The main advantages of CDMA are its robustness against fading and cross-cell interference, and its flexibility in asynchronous transmission environments.

An uplink data transfer mechanism in the HSUPA is provided by physical HSUPA channels, such as an Enhanced Dedicated Physical Data Channel (E-DPDCH), implemented on top of Wideband Code Division Multiple Access (WCDMA) uplink physical data channels such as a Dedicated Physical Control Channel (DPCCH) and a Dedicated Physical Data Channel (DPDCH), thus sharing radio resources, such as power resources, with the WCDMA uplink physical data channels. The sharing of the radio resources results in inflexibility in radio resource allocation to the physical HSUPA channels and the WCDMA physical data channels. In CDMA, which is a non-orthogonal multiple access scheme, the signals from different users within the same cell interfere with one another. This type of interference is known as the intra-cell interference. In addition, the base station also receives the interference from the users transmitting in neighbouring cells. This is known as the inter-cell interference.

Uplink power control is typically intended to control the received signal power from the active user equipments (UEs) to the base as well as the rise-over-thermal (RoT), which is a measure of the total interference (intra- and inter-cell) relative to the thermal noise. In systems such as HSUPA, fast power control is required due to the fast fluctuation in multi-user (intra-cell) interference. This fast fluctuation will otherwise result in the well-known near-far problem. Moreover, as uplink transmission in an HSUPA system is not orthogonal, the signal from each transmitting UE is subject to interference from another transmitting UE. If the signal strength of UEs varies substantially, a stronger UE (for example, a UE in favourable channel conditions experiencing a power boost due to constructive short term channel fading such as Rayleigh fading) may completely overwhelm the signal of a weaker UE (with signal experiencing attenuation due to short term fading). To mitigate this problem, fast power control has been considered previously in the art where fast power control commands are transmitted from a base station to each UE to set the power of uplink transmission.

When an orthogonal multiple access scheme such as Single-Carrier Frequency Division Multiple Access (SC-FDMA), which includes interleaved and localized Frequency Division Multiple Access (FDMA) or Orthogonal Frequency Division Multiple Access (OFDMA), is used, multi-user interference is not present for low mobility and small for moderate mobility. This is the case for the next generation UMTS i.e. LTE system. LTE system employs SC-FDMA in uplink and OFDMA in downlink. As a result in the case of LTE, the fluctuation in the total interference only comes from inter-cell interference and thermal noise which tends to be slower. While fast power control can be utilized, it can be argued that its advantage is minimal. Hence, only slow power control is needed for orthogonal multiple access schemes.

Nokia's Point, Click, Find

Nokia launches beta of 'Point & Find' system for mobile phones, letting consumers scan images for search with their camera phone.

The service can currently be downloaded in the US and the UK, on selected handsets. The phones supported by the current beta are the Nokia N82, N95, E66, N81, N76, E51, 6290, 6124 Classic, 6121 Classic, 6110 Navigator, and the 5700 Xpress Music.

Nokia has launched a beta of its new Point & Find system, which lets mobile phone users search for information on an object by looking at it with their handset camera.

Philipp Schloter, Nokia’s general manager for Point & Find, explained: "Simply by pointing their camera phone at a poster for a new movie, people can watch the trailer, read reviews, and find the closest cinema where it is playing.”

Other uses suggested by Nokia include scanning barcodes for prices, looking at items for sale and being sent more details on where to shop or coupons, or eyeing objects in a museum and being sent multimedia information about it.

The open platform system uses the camera to look at images, GPS positioning to decide where it is, and the internet to search though a database of tagged objects. When an image is recognised, links to content – such as film times or prices – are sent back to the user.

Nokia doesn’t just want consumer feedback, but is looking to hear from businesses about their ideas for the tech – click here for the Point & Find business site. It’s already being used by the Body Worlds exhibition at the O2 in London, so pointing the camera of a Point & Find phone at related advertising should bring up data on the show.

Nokia favours LTE by dismissing WiMax

In the past few days the argument between WiMax and LTE camp has intensified. Both the camps are grabbing every single opportunity to pass disparaging remarks over the other. Evidently both WiMax and LTE are trying to be 4G bearer and in order to do so they are just pushing things to the limit.

It’s very well known that Nokia although has chosen LTE as their 4G technology, are still part of WiMax forum.

However what is astonishing is that Nokia has now strongly come out openly to dismiss WiMax as a 4G technology. This latest development will no doubt will generate some intensifying and interesting comments from both the camps.

Nokia by dismissing WiMAX as a 4G technology standard seemed to have solidified its support for Long Term Evolution (LTE) technology while comparing WiMAX's future to that of Betamax, the video format that met its demise when VHS triumphed in the 1970s and 1980s. In a recent Nokia launch event in San Francisco Anssi Vanjoki, Nokia's head of sales and manufacturing said the following:
"I don't see that WiMAX is taking hold anywhere in a big way. I don't think the future is very promising for WiMAX. This is a classic example of industry standards clashing, and somebody comes out as the winner and somebody has to lose. Betamax was there for a long time, but VHS dominated the market. I see exactly the same thing happening here."

The words above are really strong as far as dismissing WiMax as a 4G technology is concerned.

Nokia has wavered in its support for WiMAX in the past, but this is by far the strongest condemnation the world's largest handset maker has made of the technology. Nokia quite rightly present WiMAX's lack of backwards compatibility as one of the reasons why they think LTE is the future and for that very reason call WiMAX a niche play.

However it still remains to be seen whether Nokia is completely abandoning WiMax as it is still involved in WiMAX business development efforts.

Albeit it is still an immense argument as what will be 4G. Clearly from the dominant mobility operator perspective the trend is towards LTE. Any technology that gets rolled out has to provide global backwards compatibility because networks don't appear overnight. The only technology that offers you backward compatibility to CDMA and TD-CDMA and wideband-CDMA is LTE. It makes a huge difference because you're not building greenfield networks; these are evolutions of existing networks and the user experience has to be maintained. From that perspective, WiMAX doesn't quite have the same capability.

I don’t want to sound too harsh on WiMax and I think there might be a place for WiMAX as a fourth generation niche technology but I believe over time, LTE will be the standard bearer for 4G globally. The (WiMAX) technology itself, there's nothing wrong with it; it's strong and it ultimately will work. The question is whether there will be a market.
