Shanzhai Mobile Phones: 'Bandit Phones' or 'Fake Phones' from China's Wild West



Have you heard of these brands called NokLa, Samsung, Nukia, HiPhone, etc. ? These are the 'fake phones' manufactured in China.

In 2008, an estimated 150 million, or 20 percent, of the 750 million handsets produced in China were either counterfeit or off-brand phones, according to CCID Consulting, a market research firm based in Beijing. Of those, over 51 million were sold in China while the remainder were sent to foreign markets.

Known here as "shanzhai ji", or bandit phones, China's gray market handset industry was virtually non-existent just a few years ago. While a handful of illegal companies produced black market mobiles, they often were of poor quality mainly because the technology needed to make them was hard to come by and even harder to master.



This all changed in 2005 when Mediatek, a microchip design company from Taiwan, developed what experts call a turnkey solution -- a platform that integrated many complex mobile phone software systems onto a single chip. This made it much easier and cheaper to build handsets and churn out new models at astounding speeds.

"[Mediatek] basically commoditized the entire market," said Jonathan Li, founder of Shanghai-based technology design studio Asentio Design. "They made it really simple and really cheap to make your own phone. Almost anybody could do it."

The shanzhai business got another boost a couple of years later when the Chinese government relaxed regulations limiting the number of companies that could manufacture handsets, lowering the entry barrier for hundreds of entrepreneurs eager to have a piece of the world's biggest mobile phone market.

"It is so easy to do because this whole ecosystem is in China," said Weaver. "It isn't so complex for a guy to figure out by watching how the global supply chain works in the mobile handset space to do his own thing."

By 2008, an estimated 3,000 to 4,000 shanzhai businesses had emerged, many with fewer than a dozen employees operating in offices sometimes comprised only of a back bedroom in a small apartment or basement of a private home. Some blatantly copy major brands, producing knock-offs with slight twists in their names, others come up with special makes of their own.

Either way, the shanzhai phenomenon has not gone unnoticed by legitimate handset manufacturers. The gray market phones, which typically sell for around $100, have already driven down the prices of brand name mobiles and are beginning to take away their market share, too.

"You cannot compete with them. You can't," said an employee of Chinese telecom equipment maker Huawei Technologies who spoke on the condition of anonymity. "It is almost impossible to make a profit [from handsets] now because of shanzhai."

Some manufacturers, like Nokia, say they are working with the Chinese government to crackdown on the counterfeiting companies as well as raise awareness about the potential dangers of the fake phones, some of which have had exploding batteries or expose consumers to abnormal amounts of radiation.


The market for Shanzhai cell phones lies not only in China, but also in the surrounding developing countries in Asia or even third world countries in Africa and Latin America. They identify overlooked/underserved market segments by incumbents like the rural areas and focus on these segments. The outstanding sales performance of Shanzhai cell phones is usually attributed to their low price, (usually lower than $50), multi-functional performance and imitations of trendy cell phone design. Although Shanzhai companies do not use branding as a marketing strategy, they are known for their flexibility of design to meet specific market needs. For example, during Barack Obama’s 2008 U.S. presidential election campaign, Shanzhai cell phone companies started selling “Obama” cell phones in Kenya, with the slogan “yes we can” and Obama’s name on the back of the cell phone. They also designed “Bird Nest” and “Fuwa” cell phones in light of the Beijing Olympic Games.
Who gains from Shanzhai Phones?
None of the stakeholders seem to gain from these low quality phones.
The phones are low in quality and do not necessarily follow the safety standards. Most of the times, the radiations from these phones are beyond the permissible limits and can cause serious damage to the health of the consumer. The FCC has adopted limits for safe exposure to radio frequency (RF) energy. These limits are given in terms of a unit referred to as the Specific Absorption Rate (SAR), which is a measure of the amount of radio frequency energy absorbed by the body when using a mobile phone. The FCC requires cell phone manufacturers to ensure that their phones comply with these objective limits for safe exposure. Shanzhai phones do not follow the SAR norms.
Most of the Chinese handsets have dual SIM slots and allows the consumers to put SIM cards of two different operators. This means that operators would have to share their ARPU with other operators and the competition would lead to lower ARPU and multiple SIM phenomena
The Shanzhai phones do not pay any taxes of regulatory fee resulting in revenue losses to Governments across the world wherever they are sold. Even the Chinese government is in a fix now as the exports benefits given out to these handsets are over claimed. Moreover, since the Shanzhai phones do not have an IMEI number, there is an increased threat from terrorists as it is very difficult to catch a terrorist who uses a mobile handset without IMEI
According to Taiwan's National Communications Commission, people who sell or buy "Shanzai" mobile phones via the Internet or in electrics marts will face a fine of up to NTD300,000, which is about CNY60,000, in Taiwan.
According to reports in Taiwanese local media, NCC recently stated that under the Administrative Regulations on the Controlled Telecommunications Radio-Frequency Devices, Taiwan residents should bring no more than five "Shanzai" mobile phones from the overseas markets at one time and the number should be limited to two if the mobile phones are sent by post.
According to reports in Indian local media, the India government has decided to set stricter quality limits to imported mobile phones, dairy products, and toys and these measures reportedly target China.
The reports quoted the director of the Foreign Trade Bureau of India by saying that from now on, mobile phones without International Mobile Equipment Identities should not be imported to the Indian market, which means Chinese-made "shanzai" mobile phones will not be available in the country.

August 2009: Mobile TV Roundup



Qualcomm is slowly building content for its Flo TV mobile service for cell phones with the recent announcement that Discovery Communications launched a Shark Week Mobile Channel.
Discovery Channel’s Shark Week programs are scheduled to air on the
Flo TV service through Aug. 14.

Flo TV uses the analog spectrum previously occupied by television broadcasters, and offers programming from several of the large network brands. Flo TV President Bill Stone says he envisions expanding the service from cell phones to cars and other consumer electronics products.

Flo TV, however, is not the only mobile TV service. AT&T CruiseCast launched a satellite-based television service in cars June 1.

CruiseCast, which is really an AT&T logo slapped onto RaySat Broadcasting equipment and services, offers 22 TV channels and 20 satellite radio channels. Its satellite antenna is a fat disc the size of a Bundt cake affixed to the roof of a vehicle.

The service costs $28 a month, plus $1,300 for equipment, which requires certified installers who charge an additional $200-$300, says Jim Llewellyn, who demonstrated the service July 31 in San Diego.


If you feell you're missing out on The Ashes action, you can now watch the Ashes for free on your W995.

A 3-month pass for the Sky Mobile TV service now comes bundled with the device exclusively on the 3 Network.

With the service, you can watch eight made-for-mobile channels that use highlights content from the Sky Sports 1, 2, 3 and Xtra channels. You’ll also be able to watch live matches right on your W995 too.

Australian cricketers Glenn McGrath and Matthew Hoggard appeared at the launch of the new bundle, and McGrath expressed his thoughts on the new bundle, saying ”the Sony Ericsson W995 on 3 is a real must for any dedicated cricket fan. To be able to access crucial games via Sky Mobile TV on the go, especially when a tournament like The Ashes is on is invaluable to me.”

After the initial 3-month period, Sky Mobile TV will cost you £5 a month. So, while the savings aren’t amazing, amounting to a whopping £15 in total, it’s still a great feature to have right now if you’re a cricket fan.



Testing of free mobile digital TV for cell phones, netbooks and other on-the-go devices is ramping up in the weeks ahead, and the first devices that can provide such broadcasts should be on store shelves by next year, according to the broadcaster-based group behind the effort.
"Just like you turn on your TV today at home and watch live and local broadcast television, you will turn on your handset and be able to watch live and local broadcast television," said Anne Schelle, executive director of the Open Mobile Video Coalition.

Trials are underway around the country in cities such as Chicago, New York and Raleigh, N.C. The biggest test pond will be Washington, D.C., where broadcasters have the attention of what may be the nation's most powerful audience — politicians. "We already have two stations on the air there, and we'll have the rest of our stations on air by next week," said Schelle.

Cell phones are probably the largest single group of devices that could receive local TV programming.

"There are 250 million of them out there," said Schelle. It's not clear whether wireless carriers are as enthusiastic.


MobileCrunch has picked up an interesting story from AV Watch - who themselves have spotted a USB tuner that plugs in to your TV, and then streams out 1-Seg (that’s a Japanese TV standard) formatted TV that your iPhone/iPod Touch can pick up via an App running over WiFi. Nice.

The iPhone has been at somewhat of a disadvantage for a time, because unlike a lot of other phones in Japan, it can’t natively pick up a TV signal - Japan is one of the places where Mobile TV has worked (but there are a number of specific reasons for that….), so this little bit of kit solves an issue for people who need their TV fix.

The USB device is called the SEG Clip, and is sold by I-O data it follows a previous device that was more of a standalone unit from Softbank Mobile - that one was it’s own receiver, transmitted the data by WiFi, but also double as an extra battery if you plugged it in to an iPhone.



WISH-TV today announced the expansion of its mobile offerings to include a new application for BlackBerry smartphones. This mobile application is the latest addition to 24-Hour News 8’s fully synchronized television and digital offerings that are available free of charge at www.wishtv.com .

WISH-TV unveiled its iPhone custom application with great popularity and much success in May 2009. In addition to these specialized applications, 24-Hour News 8 is also available via any web-enabled mobile device.

LIN TV , WISH-TV’s parent company, in conjunction with News Over Wireless (NOW) has developed the custom BlackBerry smartphone and iPhone applications for each of its 27 local television stations. Six LIN TV stations, including WISH-TV, launch the BlackBerry smartphone service today. LIN TV is the first in its local markets to provide instantaneous and on-demand access to its local news, sports and entertainment, as well as video, weather forecasts and traffic reports to BlackBerry smartphone subscribers.

Six LIN TV stations launched the BlackBerry service last week, including WISH-TV, WAVY-TV, KRQE-TV, WANE-TV, WALA-TV and KXAN-TV. LIN has been among the more aggressive broadcasters in the deployment of its content over nontraditional platforms.

Media Content and Communications Services (MCCS) has made its Hindi, Marathi and Bengali news channels -- STAR News, STAR Majha and STAR Ananda -- available on the mobile TV platform.

The content of all three channels will be streamed live, including the ads that appear during the news programmes. The content will be available on the 3G networks of MTNL and BSNL. However, the company claims that their mobile TV option will also be made accessible to subscribers of other telecom operators, who offer 2.5G services.

Currently, only two mobile operators -- BSNL and MTNL -- offer 3G services in India. The video content delivery process is faster on 3G mobile networks, as compared to 2.5G.

What is going to be 5G ?



I suppose its pretty pointless to talk about 5G because LTE also known as 3.9G is not yet deployed. Nevertheless, I saw various discussions about 5G in various forums recently.

Just to recap, LTE or 3.9G will take DL speeds upto 300Mbps and UL to around 75Mbps. LTE-Advanced also known as 4G will take the speeds upto 1Gbps in slow mobility scenario and and in high mobility the rates could be upto 100Mbps. So what about 5G?

Well honestly its too difficult to forsee and speculate the rates 5G would provide. In fact 5G may be a completely different paradigm and use another yardstick to measure technological progress. Infact the ITU has moved away from the 'generation' concept and even though its accepted that LTE-A is 4G, its not referred to as 4G by ITU. ITU does not mention 4G anywhere in its next generation acronyms. The term used is IMT-Advanced.

So lets speculate what 5G could be.

I think 5G will be more about reliability and convergence of technologies. Imagine a phone with upto 8 MIMO's and simultaneously its using dfifferent technologies. So a user is connected to the web using multiple technologies and at any instant of time he is getting multiple streams from different sources. When one of these sources fail then the other technology can simply take over and provide the connection. In a simple case if we map this to today's technology then we would have one antenna connected to HSPA, one to WiMAX, one to WiFi, one to UWB, etc., etc.

Hopefully IMS (or another similar technology) will become reality much earlier but even if it doesnt then hopefully by the time 5G will arrive its already operational. Mutiple devices can be connected by the same contact and presence rules can control them. It can help with other services like Messaging and PoC.

Television streaming should become completely seamless and it should be possible to provide 100's of channels without any spectrum limitations.

The cell sizes can become extremely large and cells can have say 80% overlap but there would be no interference. This would even give opportunity to have Femtocell like devices that can provide coverage for say upto a kilometre and it would cause no interference. This should also help get rid of cell-edge rate problem and can help avoid congestion, capacity crunch, etc.

Cloud computing can hit the mobile technology as well and the phones can do amazing things withouth much of the power required. A bit like the 'sixth-sense' technology case where the computation power is in the cloud and the phone is just a device to connect to the web. Infact the cloud concept could be extended where different gadgets can become part of the cloud so maybe your refrigerator can be processing your data if you are near it or maybe you television is if you are near it. The end user should not be aware and shouldnt care as long as his job is getting done.

I suppose when these many features will be available in a technology then the applications can do amazing stuff, only creative developers will be required to come up with new and amazing innvovative ideas.

These are just ideas, please feel free to add yours.

Ps: And ofcourse we would need support to Voice and SMS ;-)

SMS Ads: Earn Money or Get Discounts

Sometime back I wrote about SMS becoming cheaper in many parts of the world and that can lead to a deluge of SMS SPAM. Last week I read about someone arguing for SMS Ads:

The mobile advertising market is growing in size at a prodigious rate, but in absolute terms, is still tiny in value compared to other media such as print, broadcast and online. There is a perception within the advertising industry that the mobile space is a difficult one to address, with limited inventory and reach, compromised display banner ad formats, and a lack of metrics to provide proof of a return on investment.

To a certain extent, these criticisms are valid, with some factions of the mobile marketing industry having something of a blinkered ‘WAP banner ad’ mentality. But there are alternative formats that address many of the current needs of the advertising world: chief amongst these has been known to users, providers and advertisers alike for decades – the SMS text message.By injecting targeted adverts into existing SMS service messages (or indeed using the whole SMS for a marketing message) and, crucially, providing an interaction mechanism that is measurable on a per-advert, per-user level, SMS advertising addresses the key needs of advertisers and marketers, namely:
  • High volumes of inventory – there are billions of service SMSs sent globally each day.
  • Reach – the ability to receive and interact with SMS is ubiquitous: every mobile phone has this ability and hence all users can be reached with campaigns.
  • Targeted – such a personal medium as the mobile phone allows for highly contextualised advert delivery based on a wide range of parameters, including the content of the service message, location, time of day and other user information.
  • Measurable – the ability to determine exactly how many individual users click to interact with the advert (either click-to-call or click-to-mobile site) provides not only a measurable ROI for the campaign, but the opportunity to inform future ad delivery on an individual basis.

The preconception of SMS advertising is of mobile spam: sending the same message to (an often unqualified) list of mobile numbers. True SMS advertising, and where the most value lies for all involved, is in delivering the most appropriate contextualised advert for a (known) user at a given time, based upon as wide a range of parameters as possible, and providing measurement of interaction rates for the campaigns. In this scenario, SMS represents premium advertising inventory, achieving effective CPM rates in excess of £100 – many times that of other mobile display advertising formats – either on a straightforward volume or a cost-per-click basis.

The winning combination of personalised delivery and measurement of individual consumer interaction with adverts offers the prospect of extending the advertiser’s engagement with the consumer through the cycle of attracting, engaging and retaining them as a customer. By linking individual consumer’s responses with customer service or CRM systems, a richer picture of their preferences can be built to drive increased relevance of future adverts and improve loyalty. The direct interaction mechanism offered by a ‘click-to-action’ mechanic in an SMS offers an easy to use customer acquisition method – a consumer can be connected directly to an existing call centre or further product information, without being required to remember or re-enter any details.

There are different approaches in case of SMS based advertisement. A simple approach is to offer customised discounts on certain products where the user can take a SMS voucher and get a discount on certain products. Another approach becoming popular in India and China is to get paid for receiving SMS Ads. In Japan and Korea, users can receive QR codes that they can take to a shop and obtain discounts.

A similar but slightly varying approach is Bluetooth based proximity marketing. Here the user is sent ads over Bluetooth when he/she is in a certain area and a Bluetooth ads server is available to pump ads. In this scenario its is simple choice for the user because he can decline the ad. Also Bluetooth can be switched off thereby avoiding nuisance of receiving ads over Bluetooth.

So some people may be interested in SMS ads and discounts and maybe somepeople may become Millionaires by receiving lots of SMS's but for majority of the people this may be more of an annoyance rather than the promised boon. In case of Emails you have a filter where SPAM can be filtered out but maybe difficult for SMS. Ad based SPAM maybe something that can kill off SMS as people may find a way to switch off SMS on their phones to avoid unnecessary interruptions and text messages.

Already in different partss of the world, the legislators are acting against SMS SPAM. There is already an SMS SPAM Act in Australia for long time. In USA the Senators want to ban the SMS Spam. I am not sure where EU and UK stand on this issue. Hopefully this is one issue where everyone will act together and hopefully wont be much of a problem in future.

Multi-Standards Radio Base Station (MSR-BS) in 3GPP Release 9

I wrote about Future Mobile Terminals earlier which will probably be Multiservice, Multinetwork and Multimode. A similar approach would be needed for the network side. 3GPP is working on Release-9 feature of Multi-Standard Radio (MSR-BS). The 3GPP Spec 37.900 is not yet available but a draft should be available soon.

Research and Markets have already released a report arguing about the benefits of MSR-BS. Last year Ericsson released the RBS 6000 series products that has MSR support. Huawei and Nokia Siemens Networks are also working on similar products under different guises. Martin has blogged about this topic as well earlier in case you want to refer to.

According to Research and Markets report the terms used for this technology is Multi-Standard Radio Base Station (MSR-BTS/MSR-BS), Multi-Mode Radio Base Station (MMR-BTS/MMR-BS) and Multi-Radio Access Technology (Multi-RAT). The name in standards usually is MSR-BS.

So what is MSR-BS? The 3GPP definition is: Base Station characterized by the ability of its receiver and transmitter to process two or more carriers in common active RF components simultaneously in a declared RF bandwidth, where at least one carrier is of a different RAT than the other carrier(s).

In very simple terms, a single Base Station will be able to simultaneously transmit different radio access technologies from a single unit. So a unit may be for example transmitting GSM, WCDMA 2100 and LTE 2600 simultaneously.

The number of technologies supported by a BTS will be an implementation choice. With technology maturing it wont be surprising to have upto 4-5 different technologies in a MSR-BS in the next five years.

The advantage the mobile operator will have will not only be monetary but there will be possibility of space saving. But as the old english proverb says, they will be "putting their eggs in a single basket". If one unit stops working then the coverage in the area goes down. There may not be an option to fallback on different technology.

The way this MSR-BS are implemented will be definitely based on Software Defined Radios (SDR). The advantage with SDR will be that in different parts there is a slight frequency variation for different technologies like GSM-850 is specific to USA whereas the rest of the world uses GSM-900. These small variations will easily be customisable with these MSR-BS and optimisations wont be too far off.

Different Band Categories have been defined for different scenarios. For example Band Category 1 involves deplyment where GSM wont be present. Only LTE and WCDMA is present there. Band Category 2 involves frequency bands where GSM, EDGE, WCDMA and LTE may be present. Band Category 3 is designed with TDD and TD-SCDMA in mind.

Simplicity of LTE and its differences with UMTS RRC

LTE is gaining pace as the days pass by and everyday we hear some sort of milestone achieved by some company towards the ultimate aim of LTE product. RRC is one of the main components of Layer in the LTE protocol stack just as it was in UMTS. Certainly LTE RRC looks simpler in terms of the no of states and off course the length of the RRC document. Below are some of the important changes in LTE RRC and its difference with the UMTS system.

RRC State: In LTE there is only 2 RRC states i.e. RRC_IDLE and RRC_CONNECTED whereas in UMTS system RRC has a 5 state i.e. IDLE, CELL_FACH, CELL_DCH, CELL_PCH and URA_PCH. One of the reasons why we don’t have CELL_FACH and CELL_DCH state is because there is no concept of common and dedicated transport channel in LTE. In LTE the data transfer will be done through the defined shared transport channel. Therefore this will simplifies the RRC State machine handling and improves RRC performance. This will also simplify the RRM algorithm which decides RRC states.

Signalling Radio Bearers: In LTE there is only three SRB is defined i.e. SRB0, SRB1 and SRB2 whereas in UMTS system RRC has 4 SRBs i.e. SRB0, SRB1, SRB2 and SRB3 (optional).
SRB 0: In LTE SRB 0 use RLC TM entity over CCCH logical channel in DL whereas in UMTS system it SRB 0 is sent on RLC UM entity over CCCH logical channel in DL.

MAC entity: In LTE there is only one MAC entity which needs to configured whereas in UMTS system there is 4 different MAC entity based on different type of transport channel i.e MAC-d (DCH), MAC-c/sh (FACH, DSCH), MAC-hs (HS-DSCH) and MAC-e (E-DCH). In UMTS system the state machine which is handling MAC configuration is quite complex. During state transition from CELL_FACH to CELL_DCH or CELL_DCH to CELL_FACH lots of signalling was involved. In LTE, since there is only one MAC entity which is easier and simple to configure and thus have very simple State Machine.

Radio Bearer mapping: In LTE Radio bearer mapping would be much simpler than the UMTS system because of there is no common and transport channel defined in LTE.
In LTE there is no RRC connection mobility defined like cell update and URA update.

Domain Identity: In LTE, there is only one domain identity i.e. PS domain and which is implicit no need to specify anywhere in signalling unlike UMTS system which has CS domain and PS domain. Because of a single domain in LTE the signalling overhead and complexity in RRC design has been reduced.

System Broadcast Information: In LTE, MIB includes a limited number of most frequently transmitted parameters and SIB Type 1 containing the scheduling information that mainly indicates when the SI messages are transmitted where as in UMTS system, MIB includes the frequently transmitted parameters was well as scheduling information.

Channels: In LTE RRC there is no need to define the downlink transport channel configuration in the RRC Reconfiguration message as it uses only shared channel. This will reduce signalling message size effectively. All DL-SCH transport channel information is broadcasted in system information.

Power Consumption: The above point introduces another very critical feature of DRX calculation since all DL data is on the shared channel. E-NB can tell the UE when to decode/listen over the radio frame. This will optimize UE power consumption.

Paging Type: Since there is no CELL_FACH and CELL_DCH state in LTE there is only one type of paging required where as in UMTS system there is two type of paging defined.
Reconfiguration: In LTE there is only one reconfiguration message to reconfigure all logical, transport and physical channel where as in UMTS system there are number of reconfiguration message i.e. RB reconfiguration , TRCH configuration, PHY configuration. Thus there is less signalling message or overhead in LTE for the reconfiguration.

Reduced Latency: Since there is no RNC or NBAP protocol in LTE, this reduces the latency of the RRC connection establishment and RB management procedure.
Single UE identity: Since there is only one shared MAC entity, there is no need to define URNTI, ERNTI, HRNTI, SRNTI etc in LTE.

No Activation time: In LTE, there in no need to define activation time. Because of this there are lots of synchronizing complexity in 3G-RNC systems i.e. Synchronizing Radio link procedure based on activation time, synchronizing between the various MAC entity. This reduces significantly latency during establishment and reconfiguration of radio bearers.
RRC State: In LTE, there in no need to specify the RRC State in RRC message.

CQI Reporting: For network control mobility, there is one feature which become very important and critical i.e. CQI Reporting. As in LTE the CQI reporting should be fast and correct for taking decision for mobility.

Signalling connection release: There is no signalling connection release procedure in LTE, since there is only one domain i.e. PS domain. Also the UE context is shared between the MME and ENB and if UE is active in ENB then it should be active in MME also.

'Sexting' craze catching on in UK as US teen hangs herself



Eighteen-year-old Jessica Logan had it all. She was bright, pretty and popular. Her mum Cynthia describes her: "She was vivacious, she was artistic, she was fun, she was a good kid."
She was completely in love with her boyfriend but one day she sent him a text, a nude photo of herself, to show him how much she cared.

When they broke up he sent the picture to hundreds of teenagers in their town in Ohio to get back at her.
Jessica's friend Lauren Taylor told reporters: "She was being attacked and tortured. "When she would come to school, she would always hear, 'Oh, that's the girl who sent the picture'.''

The bullying spiralled out of control and Jessica began skiving off school. In June last year she couldn't take it any more and killed herself.

I wrote about 'Sexting' some months back and sure its become much more popular and dangerous since then.

According to the charity Beatbullying, one in three 11-18 year olds has received a "sext" – a sexually explicit message sent by phone or email – and girls are regularly being bullied into taking and sharing explicit photos of themselves. There is also a fear that these images may be falling into the hands of sex offenders. It is time for this private practice taking place on the tiny screens of children's mobile phones to be brought to light in the public domain.

The schools minister (UK), Diana Johnson, said children who were facing sexual bullying should tell a teacher. "We are committed to tackling all forms of bullying – including bullying using the internet and mobile phones, and sexual bullying," she said. "It is important that young people being bullied know that they can report it and that it can be stopped.

Maybe in couple of years we may have 'Minister for Mobile Communications' in UK or US to handle such problems :-)

Didnt I tell you, phones are too complicated ;)



As the former head of the British army, General Sir Mike Jackson oversaw a range of regiments armed with some of the most complex weapons and technology ever invented.

But yesterday, the general was left embarrassed live on television after he was defeated by a ringing mobile phone.His phone went off twice during an interview with the BBC's economics editor Stephanie Flanders, who was standing in for Andrew Marr.

Jackson was talking about compensation given to wounded soldiers when the mobile began to ring.

Flanders told the general: "You'll have to turn that phone off." Jackson apologised and after sheepishly fumbling with some buttons, managed to silence the call and put the phone in his pocket – only for it to ring again.

As he tried to turn it off once more, technology appeared to get the better of him.

In the end, Jackson lost his patience, turned around in his seat and flung the handset off camera across the studio in exasperation. After the sound of a heavy crash rang out, he returned to face Flanders and the interview with as straight a face as he could manage.

Now even Texting can be dangerous :-)


Police say a truck driver was texting on one mobile phone while talking on another when he slammed into a car and crashed into a swimming pool.

Niagara County sheriff's deputies say 25-year-old Nicholas Sparks admitted he was texting and talking when his flatbed rescue truck hit the car in Lockport, which is outside Buffalo.

The truck then crashed through a fence and sideswiped a house before rolling into an in-ground pool.

Police say the 68-year-old woman driving the car suffered head injuries and was in good condition. Her 8-year-old niece suffered minor injuries.

Sparks was charged with reckless driving, talking on a cell phone and following too closely.

iPhone Apps and the Smartphones's Apps war


Smartphones had done amazing this to the consumers in the past couple of years especially after the launch of iPhone. These days there is immense concentration on the development of quality applications Application which can lure the customers in real time and are useful to them. I remember initially mobile games created similar kind of furore but I personally believe that this is different. These days application are developed not only for fun sake but also providing the customers some really value added service.

iPhone certainly is leading in the race in this regard and application developers are hugely receptive to the ideas which can be translated into a iPhone application.

Lance Stewart is one such person who came up with the idea of latest iPhone application called Tube Exits.
It came to him when he was trying to get out of Oxford Circus tube station in a hurry. Anybody who’s has experience the London’s train station during th rush hours knows very well that you find yourself behind a huge crowd of people blocking the way to the exit.

After experincing similar this Stuart thought that what he needed was to get the jump on the crowds by knowing which carriage he should board to arrive at the platform exit. If he somehow knew, for every station platform on the London Underground network, which carriage would arrive at a station next to the platform exit, he would never be stuck behind foot-dragging tourists or daily commuters again.

He thought it would be good idea to put all this information into the form of an iPhone application for other commuters. Dreaming of making something out of it he compiled the information for more than 700 platforms at London Underground's 268 stations. As he was not the person who can develop the app of his own so together with the collected information he approached an apps developer with his idea.
The outcome of this Stuart’s initiative and idea was the Tube Exits app for iPhone which was launched on 16ht June and has become very popular since then.
The app comes in two versions: One is free but only gives you the information for the Underground's busiest 12 stations; the other costs £1.79 and covers the whole network. This price is probably a price of a zone 1 ticket, but you could use it again and again.

Stewart is now involved in developing a similar app for the Paris Metro and sees no reason why his original idea can't be applied to other metro networks around the world.

Tube Exits is just one of an estimated 100,000 apps that will exist by the end of this year. Most of the apps these days are mobile applications designed to be used on Smartphones such as iPhones or BlackBerrys.

Recently the apps industry has grown exponentially where the total number of Apple's App Store downloads only recently passed the 1.5bn mark.

The App Store's success is huge incentive for Apple and is really giving a tough time to its competitors such as Research in Motion (who make BlackBerrys) and Nokia (the world's biggest mobile phone maker). The App Store's staggering success has led nearly every maker of a smartphone operating system to mimic Apple's business model: make it very easy for smartphone users to buy or freely download software created by from third-party developers.
Indeed Apple has become an icon phone and at the moment Apple has something of a stranglehold on apps e.g. Tube Exits can only be used on Apple mobile hardware (ie iPhones and iPod Touches).

What's especially striking about apps is how quickly they have become popular and are the real money spinners for smartphone companies specially Apple. I remember it very well when the iPhone was launched, there were many sceptical voices. It was too expensive, too readily nickable, too much of a triumph of what techies could do over what customers wanted to be for it to be a success. Apps have changed all that where Apple gets a significant chunk of revenue from the sale of its Apps. Apple is smartly doing what Microsoft has been doing until now, binding the applications and software to its products.

Apple is also not leving any stone unturned in fighting for the superiority of it’s application. This can be best provide by Apple recent victory in front of the advertising watchdog, with a ruling that it is free to claim its iPhone applications store is superior to a rival service offered by Google.
The Advertising Standards Authority rejected complaints from fans of Google's G1 smartphone that a TV ad for Apple's App Store was misleading.

"Yep, there's an app for just about anything," a voiceover in the advert said. "Only on the iPhone."

The days ahead will be interesting and messier in terms Smartphone companies claiming for smart and beautiful apps.

LTE Band 13 mystery

Interesting observation from Hooman Razani in LTE university blog:

It was in a classroom, after I had opened Technical Specification 36.101 for handset radio transmission and reception that I suddenly noticed for the first time something odd about Band 13.

I said to the class without hesitation, Band 13 [UL = 777 MHz-787 MHz & DL = 746 MHz-756 MHz] has the uplink and downlink reversed! In contrast to all other FDD bands in the table (and many other bandplans elsewhere), in this band, the higher frequency is allocated to the mobile device and the lower frequency to the base station. The normal practice of FDD paired band allocation has to do with attenuation properties of the carrier frequency and the availability of the power. The mobile side has usually been allocated the “easier” lower-frequency portion of the band which experiences smaller amount of attenuation and therefore requires less power for closing the uplink. A reversal of this allocation strategy in band 13 is a sure sign that some other problem is lurking in the background, namely interference in the form of spurious emissions.

The 700MHz band is divided into four paired blocks, A, B, C and D (an unpaired E Block is also available). The A and B blocks are guard bands. The C blocks (LTE Band 13) in this upper 700MHz band were the main object of last year’s auction. 12MHz in the middle of this spectrum belongs to the Public Safety.

A – C – D – B – [Public Safety] – A – C – D - B

A look at the structure of the auctioned UHF band shows that upper portion of Band 13 is closer to the public safety band. In order to reduce the effects of interference to the public safety band and other bands due to intermodulation effects of this carrier, the higher more “difficult” frequency has been allocated to the lower powered handset. On the other hand we can expect a slight enhancement in indoor coverage for band 13, due to further lowering of the downlink frequency .The question to ask is if this maneuver is enough to suppress the spurious emissions caused by the handsets to nearby bands. Further details after initial deployment will shed light on the mysterious case of band 13.

Nortel Acquisition and Ericsson Gameplan



Bankruptcy courts in Canada and the United States unanimously approved Nortel Networks Corp.'s request to sell its main wireless business to Swedish rival LM Ericsson.

The US$1.13-billion sale will deliver to the Swedish telecom firm Toronto-based Nortel's CDMA, or code division multiple-access technology, an older system, but one still widely deployed by mobile-phone carriers. CDMA is expected to continue to be in use in developing markets like Asia for the next several years.

However, the most lucrative portion of the sale, analysts say, comes in Nortel's long-term-evolution technology, or LTE. Nortel said it has spent as much as US$200-million annually developing the next-generation wireless gear that is expected to become the global standard in the future.

"Nortel still owns all of the LTE patents," Nortel counsel Derrick Tay said in court. Mr. Tay said Nortel owned some 5,500 patents. Of those, 600 were being "transferred" to Ericsson while none of the LTE intellectual property was being sold. Instead, Nortel will be licensing them to Ericsson, he said.

I am curious as to what does it mean by licensing the LTE patents considering the fact that Nortel is bankrupt. If the license period is something like say 99 years then it shouldnt really matter for Ericsson. I am not sure just making a guess.

Lynnette Luna, Fierce Wireless has a very interesting take on this:
Ericsson and Nokia, once the staunchest opponents of CDMA technology, found themselves in a bidding war for bankrupt Nortel's CDMA assets. The war ended on Friday with Ericsson on top and willing to pay $1.13 billion for most of Nortel's CDMA and LTE assets.


Ericsson had tried to make a go of it in the North American CDMA market following its purchase of Qualcomm's infrastructure business that was part of its IPR settlement with Qualcomm in 1999. It subsequently ended the business after failing to penetrate this market since Qualcomm didn't have much of an installed base. Nokia, now Nokia Siemens Networks, never tried to play in the North American CDMA market, and thus has a weak North American market share overall at around 5.5 percent.

However, Ericsson this year has made significant headway into the U.S. market, scoring a big LTE deal with Verizon--at the expense of Nortel--and winning a $5 billion CDMA outsourcing agreement with Sprint Nextel. Did it really need to spend $1.13 billion to gain more market share?

The answer is yes. Despite winning these two U.S. deals, the biggest criticism of Ericsson has been its lack of CDMA expertise--whether managing a network or migrating CDMA operators to LTE. Now it has both. Given the fact that Nortel's CDMA gear is in a significant portion of CDMA networks operating around the world, Ericsson now has a great story to tell. It needs that CDMA expertise to migrate customers from CDMA to LTE--especially since voice traffic will continue to run over CDMA networks while data gets routed over LTE for the foreseeable future.

For Ericsson, it's no longer about getting a foot in the door. It's about crushing the competition. Ericsson is looking forward to a future when both WCDMA and CDMA operators look to it to help them migrate to LTE. But as Ericsson CEO Carl-Henric Svanberg said on the conference call this morning, "CDMA will be the first markets to migrate to LTE so therefore it is important to us."

Meanwhile, a deal like this could be the nail in the coffin for some vendors. It's certainly not good news for NSN, which would have boosted its North American market share to 30 percent had it won the assets. And Chinese vendors ZTE and Huawei have been trying hard to make inroads into the North American market through CDMA. This deal certainly hampers those efforts.

And Alcatel-Lucent just saw its major competitor become significantly stronger. Alcatel-Lucent was the vendor with the better CDMA-to-LTE conversion story while Nortel was stuck in bankruptcy limbo.

Of course, it's not just about getting a stronger foothold in LTE. Nortel's CDMA business is a money-maker, and Ericsson executives on the call this morning said they believe the unit will continue to be profitable for the next few years as operators keep investing in their CDMA networks. There are actually operators looking to deploy CDMA EV-DO Rev. B. And don't forget the services market, a major growth engine for Ericsson. Ericsson said the deal will be earnings per share accretive within the first year.

Q2 Mobile sales: No surprises but lots of good news


Nokia, the world's largest maker of mobile phones, reported Thursday that its second-quarter operating profit fell 71 percent to 427 million euros ($600 million) from 1.47 billion euros during the same quarter a year earlier.

The company also reported that sales fell about 25 percent to 9.9 billion euros in the second quarter. But sales were up 7 percent sequentially from the first quarter of 2008.

Nokia shipped 103.2 million units during the quarter, which was down about 15 percent compared with a year earlier. But shipments were up 11 percent sequentially compared with the first quarter of this year.

Nokia said that it increased its market share sequentially for global sales of mobile phones to an estimated 38 percent. And its smartphone market share grew sequentially to 41 percent.

Toward the end of the second quarter, Nokia brought its N97 smartphone to the U.S. market.

It was bound to happen, but we didn’t think the Nokia N97 would outsell the Nokia 5800 quite as quickly as it has. However, from sales figures that have just been released, it looks like the big fight of the summer is going to be between Nokia’s two touchscreen smartphones.

The top ten phones currently being sold by Vodafone looks something like this:

1. Nokia N97 32GB
2. Nokia 5800
3. Sony Ericsson W595
4. Sony Ericsson C510
5. Samsung Jet
6. Samsung Tocco Ultra Edition
7. Samsung Steel L810
8. Nokia 6300
9. BlackBerry Storm
10. HTC Magic

South Korean company Samsung Electronics Co., Ltd recently announced the earnings results for the second quarter of the ongoing year. Globally, the company registered an 11.7 percent increase in revenues during the quarter on a yearly basis, reaching 32.51 trillion Korean won, and posted 2.52 trillion won operating profit, up 436 percent compared to the previous quarter of the year.

Samsung’s Telecommunications business also went up compared to the same time frame last year, reaching 10.04 trillion won in revenue, or a 27.4 percent increase, while the operating profit was of 1.00 trillion won, with a 10 percent margin. During the three-month period, the company says, its mobile phones sales reached 52.3 million units, marking a 14 percent increase compared to the previous quarter.

LG Electronics posted a record quarterly profit on strong mobile phone and TV sales, helping it win market share from rivals Nokia and Motorola today. However concerns over weaker margins may stall a rally in its shares.

LG, which trails Nokia and Samsung in mobile phones, sold a record 29.8 million handsets in the second quarter, up from 22.6 million units in January to March.

It posted an 11 per cent operating profit margin in handsets, compared with 6.7 per cent in the first quarter, a figure Choi said was "pretty remarkable."

The company's operating profit margin was 7.8 per cent in the second quarter and was at 4.3 per cent for all of 2008.

Fourth ranked Motorola is working to narrow losses through cost cuts in the face of sharp drops in sales, while world fifth maker Sony Ericsson is also braced for a tough second half of 2009 as a demand slump hits its stronghold mid-range products focused on camera and music features.

Apple's quarterly results were better than forecast, thanks to strong iPhone sales, including its new 3GS model.

Net profits hit $1.23bn (£953m), or $1.35 a share, in the fiscal third quarter to 27 June, from $1.07bn, or $1.19 a share, a year earlier.

The US technology giant sold more than 5.2 million iPhones in the quarter, seven times more than a year earlier.

Apple chief financial officer Peter Oppenheimer said: "We are very proud of this result, particularly given the economic climate around us."

He also admitted that Apple was "currently unable to make enough iPhone 3GS to meet high demand and we are working to improve that".

Apple also hopes to make the iPhone available in more countries than the current 18, including China "within a year".

Possible UE Categories of LTE-Advanced

Another interesting peice of information from the 3G Americas whitepaper I mentioned earlier.

3GPP RAN WG4 has begun investigating possible UE RF architectures to enable four LTE-Advanced resource aggregation scenarios for ITU-R submission purposes.

Initial analysis has focused on UE complexity and power consumption for the resource aggregation scenarios.

RAN WG4 has initially concluded that it would be beneficial for LTE-A feasibility study purposes to consider various device categories in order to enable a sufficient number of different UE categories in LTE-Advanced. One set of device categories presented by RAN WG4 is listed in the figure below.




RAN WG 4 noted in particular that it envisions the need for an absolutely lowest cost terminal. This is reflected in Category A above, which represents even a simpler UE category than 3GPP Release 8 currently allows.

...and the Android shall inherit the earth



Android fever seems to be catching on. Everyone phone manufacturer now wants to show that they are active in Android market. Few weeks back there were also rumours of Nokia launching android device (which may still be true). HTC is at the moment the leader, releasing more Android phones than anyone else.

The following is from a very interesting article in The Independent:

With four billion handsets in the world – more than twice the number of internet users, and two and half a billion more than the number of televisions – it's safe to describe the mobile phone as the most successful technology of our generation. But what's the next step for mobile communication? If Google has its way, the future is Android – and the next few months are going to be crucial to its success.

Android, in case the news has passed you by, is billed as the mobile phone operating system that will change the way we use mobiles. Where traditionally, phones have all worked differently, with usability ranging from the passable to the infuriating, Android's mission is to simplify, partially by devising a more intuitive interface, and also by making it so widely available that it becomes a standard. "Combining the simplicity of Android software with its imminent availability on a range of mass-market phones from various manufacturers, and the trend in developing countries to go 'straight to mobile', makes Android an exciting global platform for the next few years," says Richard Warmsley, head of internet and entertainment of T-Mobile.

From Android's humble beginnings as a two-person company in Palo Alto, California, through being bought up by Google in 2005, it has grown into the flagship operation of a group of 48 companies known as the Open Handset Alliance. Featuring such heavyweights of the tech world as LG, Toshiba and Samsung, its aim is to "enrich the lives of countless people across the globe" by improving mobile experiences.

The handset manufacturer Motorola is so confident the future is Android it's reportedly retired its team of 77 engineers who were working on the company's own operating system, and is now hiring software engineers familiar with Google's free alternative. Such is its potential that Android has been mooted as the software of the future for netbooks and set-top boxes as well as phones.


With any discussion of mobile phones, the elephant in the room is always going to be Apple's iPhone, which has been a huge critical and commercial success. Android phones and the iPhone might appear to be in direct competition; they are both high-spec, and similarly priced. But Al Sutton, a UK-based Android developer, thinks the situation may develop along similar lines to the home computing market: "I can see the iPhone and Android co-existing in the future in a similar way that Macs and Windows PCs do at the moment", he says. "Apple is focused on being a premium brand, whereas Android's focus is ubiquity."

Although Android phones are only rarely to be spotted in the wild in Britain right now, the groundswell of support for the system from manufacturers may well see a number of devices launched at once in the coming year. "We are not facing a shortage of offers powered by Android," claims Peter Becker-Pennrich, director of terminals marketing for Vodafone, on the brand's future product line-up. T-Mobile is similarly enamoured: "The open nature of Android, the innovation and choice it bring, mean that it will establish itself as one of the most important mobile platforms of the next few years", agrees Richard Warmsley.

Next month will see the release of the G2 Touch from T-Mobile and the Hero from Orange, both versions of a new touchscreen handset from HTC, which features a hefty five-megapixel camera with video functionality, GPS and, of course, full integration with Google products like Gmail, Google Talk and YouTube.

Digital Dividend Spectrum

3G Americas have released a whitepaper titled, "3GPP Technology Approaches for Maximizing Fragmented Spectrum Allocations". There are quite a few interesting things that caught my attention. One of them is this section on Digital Dividend Spectrum about which I have mentioned before. Here is what the whitepaper says:

The Digital Dividend refers to the reallocation of significant amounts of spectrum as a result of the switchover from analog to digital TV, a phenomenon occurring across the globe. Historically, analog TV operates in the UHF band between 470-862 MHz.

The analog to digital switchover will free a substantial amount of spectrum for new services, including digital television and mobile broadband.

Mobile services will need at least 100 MHz of this spectrum for mobile broadband. The results of WRC 07 incorporate this vision, as well as the need to promote harmonization of these bands, as reflected in the following above.

As is planned, there is no one globally harmonized Digital Dividend spectrum band. Further, the APAC countries have the flexibility to adopt the Region 1 or Region 2 plans. The important task of promoting harmonization and aligning band plans as far as possible with WRC-07 agreement, in order to realize the benefits of harmonization for their citizens, now falls to policymakers to accomplish.

In fact, the EC recently launched a consultation on Digital Dividend spectrum. Noting that importance of taking prompt action “to prevent the emergence of fragmented national legacy situations” that would stymie the development of future equipment and services in the 800 MHz band, the consultation proposes that the EC undertake two urgent actions by autumn of 2009: (1) Member States that have not completed the digital switchover would be requested to confirm switch off of analogue TV under national law by 1 January 2012; and (2) the EC would draft a Commission decision, for regulatory opinion in the autumn of 2009 and formal adoption at the beginning of 2010, on technical harmonization measures for transitioning the 790-862 MHz band to non-broadcast uses.

Credit to 3G Americas for publishing these interesting white papers.

Google G0 - Ready to go...


Designed by Taiwan's Tryi Yeh the Google-G0 is both a touchscreen phone and a slider, with four big navigation buttons for quick access to email, web browsing and more, which change depending on what you're doing. We don't see any physical keyboard anywhere, so it's probably handled virtually. On the back there's a set of speakers and a camera.

It looks like the G0's functionality persists when you plug it into its charger, and there's an image of a dock that looks like it'd either let you watch TV on your phone, or use your G0 like a remote. Check out the gallery below for more of Yeh's Google-G0 concept touchscreen phone.

On Self Organising Network Concept in Rel-8 and Rel-9

Self-Organising Networks popularly known as SON are feature of 3GPP Release 8 and Release 9. SON has been around for quite some time now and is not a new concept. Its not an evolutionary technology, rather a revolutionary technology. The first time I heard of SON was in relation to Femtocells. Remember, a Femtocell has to start in an unfamiliar environment, learn about its surrounding and then adapt to the environment.

Other terms often used to mean SON is 'Plug-n-play' or 'PnP', 'Zero Touch', 'Auto Configured', 'Self Managed...', etc. SON is a very useful feature that will allow for the automation of several tasks lowering the OPEX costs. Examples include plug and play or a cell in between existing ones, neighbour recognition and (re-)configuration, optimizations, etc. Properly implemented, it could kill off drive-testing.

In simplest of terms, SON can be explained with the basic diagram above. A new cell created in an existing environment possibly due to too many existing resources being in use or too many users in an area during a particular time (football match for example) and this cell has to look at the surrounding and adjust its conditions. The other existing cells also have to adjust tehmselves with the change in surroundings.

According to recent analysis in NEC Whitepaper on SON (available here), about 17 % of wireless operator’s CAPEX is spent on engineering and installation services. SON’s self-configuring functions are expected to eliminate many on-site operations for the basic settings and subsequent updating of network equipments, and thus reduce CAPEX.

It is also known that about 24 % of a typical wireless operator’s revenue goes to network OPEX, which are the cost of network operation and maintenance, training and support, power, transmission, and site rental. SON’s self-optimizing functions will reduce a workload for site survey and analysis of network performances, and thus reduce OPEX. Moreover, SON’s energy-saving functions reduce the costs of power consumed by the equipment.

Self-optimizing and self-healing architectures improve user perceived qualities by mitigating quality degradations that result from inaccuracies of the planning or equipment faults as early as possible and by optimizing the network parameters under interference and overload conditions.
Nomor research has got an excellent paper on SON with regards to LTE. The full paper is available here. Here is an extract from that paper.

The main functionality of SON includes: self-configuration, self-optimization and self-healing.

Self-configuration process is defined as the process where newly deployed nodes (eNBs) are configured by automatic installation procedures to get the necessary basic configuration for system operation

Self-optimization process is defined as the process where UE & eNB measurements and performance measurements are used to autotune the network

Self-healing function aims at automatic detection and localization of most of the failures and applies self-healing mechanisms to solve several failure classes, such as reducing the output power in case of temperature failure or automatic fallback to previous software version.

A Self-configuration Subsystem will be created in OAM to be responsible for the selfconfiguration of eNB. For self-optimisation functions, they can be located in OAM or eNB or both of them. So according to the location of optimisation algorithms, SON can be divided into three classes: Centralised SON, Distributed SON and Hybrid SON.


The paper also lists the Use cases and the problems ands solutions for the use cases.

NEC whitepaper on SON is quite recent and it lists the recent standards status:

3GPP has introduced SON items in its standardization path as required features for LTE deployments. Rel. 8 includes the first specifications on requirements, integration with operators’ processes, and identification of main use cases. Rel. 9 is expected to define advanced features, which will introduce self-healing and self-optimization capabilities into LTE. The SON related specifications are driven from the SA5 Working Group (WG) – mainly for architectural aspects– and the RAN3 WG – especially for the optimization of radio functions. Also, Rel. 8 defined the grounding documents for SON: “SON Concepts and Requirements” in TS 32.500, and two main use cases– “Self-Establishment of eNodeB” and “Automatic Neighbor Relation” – in TS 32.501, 32.502 and 32.511.
