3G or 4G: What should India do?
Last week I wrote about Indian subscribers getting taste of 3G as the state owned MTNL and BSNL have launched some services. I am not sure what has been launched but all I can say is there is a dismal takeup as of yet. I read an article today about how Motorola is testing 4G [sic] and this can spoil the governments plan of rasing Rs 35,000 crore (£4.6Billion: 1Billion = 100 crores).
People may start panicking that investing in 3G is now doomed and it can just cause problems for the operators in future. The reality though is much more simpler. In a simple sentence, I would say that going for 3G or LTE does not matter much. Read on.
Lets first get Hardware out of the way. Most of the Base Stations (NodeB's, eNodeB's, RNC, etc) have a major part as SDR's or Software Defined Radios. The advantage of this is that if you have bought a 3G Node B, with just software change it should be upgradable to LTE eNode B. I have come across quite a few products where the equipment manufacturers are claiming that their 3G equipment is fully upgradeable to LTE. I did blog about some of this in this post here.
The second point we should get out of the way is the terminology. For a layman, 3G is something that was introduced 10 years back in 2000 so its quite an obsolete technology. In reality, 3G is commonly used to refer to even the new developments within the 3G spectrum. For example some of the people may have heard of HSDPA which is actually referred to as 3.5G in the mobile domain. Similarly we have HSUPA which is 3.75G and so on. The latest development is going on around 3.8G and 3.85G as part of Release 8. In general usage 3.5G, 3.75G, etc. is referred to as 3G but its more than 3G (3G+ ;). The good thing is that this 3G+ is till evolving. Release 8 was finalised in Dec. 2008 and the terminals based on that are still being tested. It should hopefully be available soon.
So whats the difference between LTE and HSPA+ (also known as 3G even though its 3.8/3.85G). Not much I would say from a general users point of view. Please note I am not arguing about the fundamental technologies because 3G+ uses WCDMA and LTE uses OFDMA/SC-FDMA technologies. OFDM based technologies will generally be always superior to WCDMA ones but it doesnt matter much. The main enhancement that has happened with LTE as compared to 3G is that in 3G the bandwidth is fixed to 5MHz whereas in case of LTE the bandwidth is flexible and can go all the way to 20MHz. Now if we compare the data speeds in 5MHz spectrum then there may not be much difference between them. Now how many operators will be rolling out services across 20MHz bandwidth? More general case will be using 10MHz.
In case of HSPA+, there is a new feature that allows a UE to use couple of cells. In this case even though the bandwidth is 5MHz but due to Dual Cell feature the UE would effectively see 10MHz bandwidth. This will definitely enhance the speeds.
Now coming to devices. 3G/HSPA/HSPA+ technologies have evolved over quite few years. There are some nice sleek and cheap handsets available. The technology in it as been rigourously tested. As a result the handsets are quite stable and many different design and models available.
LTE is yet to come. NTT DoCoMo and Verizon will be the first one to roll it out probably end 2010. Initial plan is to roll out the dongles then handsets will the eventually arrive. The initial ones will have problems, crashes, etc. Will take atleast till 2010 to sort out everything.
The big problem with LTE as many of us know is that the standards have to support for the old style CS voice and SMS. This should be fixed in Release 9 which is going to be standardised in Dec. 2009 (Mar. 2010 practically). There are different approaches and maybe untill LTE is rolled out we wont know which of them is better.
Last thing I should mention is the spectrum. The consensus is that 3G operates in 2.1GHz spectrum mostly worldwide. LTE would initially be deployed in 2.6GHz spectrum. The digital dividend spectrum when it becomes available will also be used for LTE. Most of the devices for LTE will be designed that way. As a result, 3G will continue to operate as it is in the 2.1GHz band. The devices will always be available and will be usable for long time.
Considering all the facts above, I think 3G (HSPA/HSPA+) is the best option in India or as a matter of fact in any country that is thinking of jumping directly from 2G to LTE. When the time is right, it should not be difficult to move from 3G to LTE.
EU commits to LTE-A future

4 Billion GSM-HSPA connections soon.
3G Americas, announced that GSM-HSPA is expected to reach 4 billion mobile connections worldwide in September 2009. This marks a major milestone for the industry, as no other technology innovation has ever reached a scale remotely close to its penetration level – equivalent to more than six of every ten people worldwide.
Equally noteworthy is the increasing number of 3G subscribers for UMTS-HSPA which has captured an annual worldwide gain of 57 percent in the year ending June 2009, according to Informa Telecoms & Media’s World Cellular Information Service. With 377 million subscriptions worldwide at the end of second quarter 2009, UMTS-HSPA added more than 137 million new connections in 12 months.

Handset Manufacturers preparing for Ramadan
The newly launched LG GD335 and LG KP500N have special features, including a Qiblah indicator that uses an in-built longitude and latitude orientation or city references that, when used in comparison to the magnetic north, indicates the direction of the Qiblah. The two phones also come complete with Adhan and Salah prayer time alarm functions as well as Quran software, the Hijri calendar and a Zakat calculator.
With its slim 11.9 mm body, LG's KP500N is a slim and lightweight handset fully equipped with key features such as a 3.2 megapixel camera, 3D accelerometer and an Active Flash User Interface with vivid widget icons to provide easy access to commonly used functions. The LG GD335 features a 2 megapixel autofocus camera that displays photos on a high resolution 2.2 inch GVGA touchscreen. The handset also has a MP3 player and can hold up to 1GB of music, photos or data. In addition, it has Bluetooth compatability and enhanced battery capabilities through the built in light sensors.
With Ramadan approaching, the features will be a welcome benefit during the month. The phones are available at major outlets across the UAE.
“Last year’s applications were very well received, as we saw over 2.4 million Ramadan applications downloaded. And based on the feedback we had received from Nokia consumers, we have further enhanced the offering this year to include additional applications as well as upgrades to some of the existing features. The applications this year also support a wider range of devices, to include both touch and non-touch Nokia devices,” said Chris Braam, Vice President, Sales, Nokia Middle East and Africa.
Users can launch Ovi Store from the Download folder on the main menu on their Nokia device or access nokia.com/Ramadan on the PC. However when I tried searching for one of Nokia’s

Greener Base stations are must for the future
But there is now significant competition, both from new divisions of companies such as Pirelli, established telecoms companies such as Sagem and Alcatel-Lucent (who have joined together to provide the Vodafone femtocell) and large players such as Huawei of China which ships equipment to 60m broadband subscribers and is a major supplier to the Chinese mobile operators.
However there is new factor which start to develop from the past year or so, i.e the factor of energy costs. It’s not a secret for anybody how energy process has soared in the past few years and now the telecoms are getting affected by this as well. Energy costs, both to build and run mobile networks, are getting increasingly important. Operators use a phenomenal amount of power, 400GW - or 200,000 tons of carbon - and over half of this is on the radio access. While this seems a lot, this equates to 25kg per user, or the same as an hour's drive on the motorway.
There is now research in place in order to study the whole energy chain, from the carbon cost of building the base stations, macrocells and femtocells, to the running costs.
In my view after looking at the femtocells especially at the Green Radio at the Wireless2.0 conference in
There is no doubt that energy factor is going to have a significant impact on the design and manufacture of femtocells and traditional mobile phone cells. If, as expected, the market takes off with millions of devices, this is going to have a huge energy cost.
As mentioned by Nick Flaherty in his blog that the carbon emission will also be a challenge for the home grown suppliers to provide low energy solutions, both in operations and also in the manufacturing to provide truly green radio. And this will help the
There is no choice for the companies to look for the alternative and green solution. As costs of deploying solar and wind power falls and energy costs rise, carriers have started looking toward green cell sites.
Once such company who is taking a lead in this prospect is Alcatel-Lucent. It’s planning to have alternative energy-powered cellsites matches that of electrically powered cell sites, which could prompt a new wave of solar-and wind-powered base stations, even in areas where an electrical connection is available. In my opinion there is no other way round as the cost of traditional energy is increasing manifolds (together with carbon emission), the price of green technology falls and networks become more efficient, using alternative energy to provide all or part of the energy at cell sites is becoming less prohibitive
Alcatel-Lucent has been working with alternative energy in wireless for five years, but it has deployed only 300 sites, mainly in Africa and the Middle East until now, which rely entirely on alternate fuels. But in the last year especially after the recent recession the alternative energy solution become a priority which resulted in a surge in interest in those technologies.
Every body in this credit crunch are finding means to cur the cost and the operators are looking to avoid the enormous costs of transporting diesel to their remote cell.
The recession has certainly given some momentum to the alternative energy cell sites and there is no doubt acceleration towards this genuine cause.
This is purely simple Economics as Electricity is a large part of an operator’s operational budget as it feeds massive quantities of power to a highly distributed network of cell sites to support not just the base station power amplifiers and radios on-site but also the air-conditioning units necessary to power them. The increase in energy costs is being largely offset with the increased power efficiencies of most vendors’ equipment. The huge site cabinets are now getting replaced with compact modular base stations, which not only consume less power but also require far less cooling. The current generation of equipment has cut power consumption between one-third and one-half. Many new radio systems also are coming equipped with energy-saving software, which powers down the base station during non-peak hours or when relatively few customers are on the cell.
Current economic climate and energy efficiency factor will definitely serve to promote green energy sooner rather than push it off to a later date. Furthermore as the market for alternative energy solutions grows in other industries the cost of the technology goes down for telecom, sending the price of solar panels and wind turbines down. Combining the above trend together with regulatory and political environments the alternative energy solution is imminently favorable as a green solution.

Indian subscribers getting taste of Mobile Broadband
MNP is not the only thing. Many operators and equipment manufacturers are waiting for the 3G spectrum auction for some time now. The auction was recently postponed for variety of reasons. The auction will let the private operators to bid for the spectrum and they can decide if they want 3G or WiMAX or LTE. The state run MTNL and BSNL have already launched 3G and in Northern India but there have been not many takers yet. Maybe the people are but sceptical right now or maybe the lack of devices. The other thing is that people are maybe not sure if the technology they invest in will be around tomorrow or not.
MTNL is keen to experiment with WiMAX but it does not want to do it alone. There are many companies in India that have developed WiMAX protocol stacks so it may be a boost for these generally small and medium sized companies if WiMAX is deployed by MTNL. The only problem with WiMAX is that there are hardly big global names with any WiMAX devices/equipment. As a reult the prices could be higher and the consumers may have less choice. 3G and LTE will help in this scenario. Qualcomm for example is already looking forward to getting a big chunck of the Indian market.
India has a very big pool of keen technologists and they will whole heartidly embrace mobile broadband and the variety of apps/mobiles but only when they know that there will be stability and reliability. Once the ball starts rolling then the snowball will turn into an avalanche. The question is not if, but when.

DoCoMo and Verizon on track for LTE
The data transfers were made over the 700 MHz LTE networks in Verizon's first two major city test sites. Boston and Seattle are expected to be the first two cities that will go live commercially with the pre-4G technology early in 2010. Those cities each now have 10 LTE 4G cell sites up and running on the 700 MHz spectrum.
Verizon isn't yet talking about the data connection speeds. "Everything is as the team expected... But because this is a very controlled environment we don't want to put a number out on the market yet," says company spokesman, Jeff Nelson.
This has pretty much been Verizon's stance throughout -- it doesn't want to talk about test numbers that might not have much relevance on the real networks. Tests have shown connections at anything between 50 Mbit/s to 8 Mbit/s.
NTT DoCoMo was the first carrier in the world to launch a commercial 3G wireless service based on WCDMA but based on its LTE roll-out it will likely be beaten this time around by carriers in other countries.
Verizon Wireless has said it plans to launch a 60Mbps trial LTE service in two U.S. cities in late 2009, to be followed by a commercial service in 2010. European carriers are also getting behind the technology with several tests under way or planned on the continent. TeliaSonera has said it will build a commercial LTE network in Stockholm, Sweden, and in Oslo, Norway.

Kenya gets Solar Charged Phones
Kenya is home to at least 17 million mobile-phone customers, but only one million have regular access to electricity, making it difficult to recharge a mobile phone.
But the first solar-powered handset could change Kenya's telecommunication industry.

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.
