LTE and LTE-Advanced Official Logos now available

3GPP has finally decided to release the official logos and they will be using them extensively to promote LTE and LTE-Advanced. At the same time, the 3GPP website will be revamped and made to look a bit modern. This is the offical comment:

To establish the LTE term as a 3GPP brand, I have been working with the legal team to establish our claim to be the owner of the term.

In May 2008, the ETSI legal team submitted the term LTE as a trade mark, this will allow us to use the term and to be a guardian to ensure that it is not hi-jacked by external organisations. The process has now been completed for France, which allows us to extend trademark protection for “LTE” through an International Registration.

Two new logos have been created to promote the Technical Specifications and Reports for LTE and LTE-Advanced. The logos will be used to identify 3GPP deliverables that contain features that enable LTE or LTE-A.

The logos will also allow 3GPP to leverage its lead in LTE, by use of the logo on marketing material (Web sites, Brochures, Booths, etc.).

10Million+ iPhones in 2008

Apple sold 6.89 million iPhones in its FY2008 4th quarter ending Sept. 27. According to the Merc,, the iPhone was the US leader for smartphone sales during that period, surpassing the BlackBerry.

This figure is slightly below the estimates of the biggest iPhone boosters, and totals only 9.3 million phones for the year. However, MacWorld reports that Apple has confirmed that it passed the 10 million mark in the past few weeks after the end of the quarter. This means that with the Christmas season their 2008 sales should easily surpass 12 million units.

Before the iPhone was released, many (notably including Steve Ballmer) predicted they would not hit 10 million.

The company has so far sold 6.9 million iPhone 3G units, eclipsing the 6.1 BlackBerry sales pushed by RIM in the same quarter.

“Apple outsold RIM last quarter, and this is a milestone for us. RIM is a good company that makes good products, and so it is surprising that we could outsell them in any quarter after only 15 months in the market,” said Apple CEO Steve Jobs.

According to Tomi Ahonen at ForumOxford:

Apple reports it sold 6.9 million units of the 3G iPhone. That compares with 6.1 million units of the original 2G iPhone. During the past 4 quarters, total 2G and 3G iPhone sales were 11.6 million, so Apple did clear its stated target of 10 million iPhone sales during fiscal year 2008 by a happy margin of 16%.So the installed base of iPhones (2G and 3G) is 13 million today, and more than half of all iPhones in use today are 3G versions.

Bank inside a Phone

Yes you read it correctly, A Little World (ALW), a Mumbai-based company, which has come up with a unique idea: turning a regular mobile phone to play the role of a bank’s branch.

Faced with the challenge of creating affordable solutions to enable penetration of banking in rural areas, ALW came up with this solution. The equipment costs not more than Rs 30,000 (pounds 400 or $700) through which a bank’s branch becomes functional and offers facilities like depositing/withdrawing money, electronic money transfer, crediting of pension money and also having an online passbook.

Other peripherals that make up the branch are a printer-cum-fingerprint scanning machine, cash box to store upto Rs one lakh in cash and a high resolution camera. The mobile phone can store data of upto 50,000 customers including the entire identification profile comprising a picture and six fingerprint templates among other details.

A big opportunity was unlocked after RBI announced a new policy initiative to allow banks to do business using the ‘business correspondent’ model. Under this, a bank ties up with third parties like ALW’s clients Zero Mass to conduct business in far-off areas on behalf of the banks. All the mobile phones have latest security features and are connected to ALW (the technology and backend partner for Zero mass) servers using GPRS or EDGE technology. The ALW server is in turn connected to the core-banking server of the client bank due to which a transaction is made possible just like it happens in a conventional way.

The critical necessity to opening a branch though is the availability of mobile coverage at the villages and ALW has tie ups with all the major GSM mobile phone operators in the country. Zero Mass currently has tie ups with 24 banks to operate their banking operations in remote and unserviced areas across 18 Indian states.

Christened as ‘Zero Platform’ for branchless banking based on mobile, a branch is typically set up in the village grocery store or panchayat office. Peripherals like the printer and camera are connected to the mobile phone using Bluetooth technology and the entire system has been designed so that it can function even during power cuts, which the villages often experience. “The selected handset (either Nokia or Motorola) has features for encryption and decryption of data through which we can make use of a public medium like GPRS to send data,” says ALW’s Chief Technology Officer Anurag Gupta.

In a short span of a year, ALW has set up over 2,800 branches for Zero Mass across the country and has plans to increase the total number of branches to 5,000 by December this year. The accounts are opened free for a period of 10 years and Zero Mass currently boasts of over 12 lakh accounts with around 20,000 added everyday. “The mobile phone operated branch is a great idea. I fail to understand why others in the same space like us have not made use of existing technologies to come up with feasible solutions like this which offer exponential growth opportunity due to low capital expenditure,” says Gupta.

Zero Mass’s motto is to increase electronic transactions like payments and crediting of accounts , Gupta says. Keeping this in view, customers are encouraged to use the account for electronic money transfer, insurance premium payments, depositing of National Rural Employment Guarantee Scheme (NREGS) wages and pension funds in the account. As a pilot project, mobile recharge payments are also being done through Zero Mass-operated branches.

ALW gets a certain amount as technical fees for rendering its services while Zero Mass gets a percentage as commission for each deposit and withdrawal transaction made at the branch. Gupta, also a director at Zero Mass, says the way forward for the company is to make use of the platform for more profitable transactions offering bigger commissions such as mobile phone recharges and railway ticket booking.

Femtocells for Radiation proofed homes

Over the weekend, I visited an old colleague who has moved in a new development. I was surprised to get nearly no reception on both my phones which are on different networks. Just outside their house the reception was ok but inside there was none. On inquiring I found out that the developers in some new construction are giving option to people to have their house "Radiation Proofed". This means that they will paint the interior with ssome special paint and put a thin film coating on the windows. So now the occupants of the house are protected by harmful radiation from mobile antennas, other WiFi signals, UV radiation, etc., etc. What people dont tend to realise is that their mobiles will become nearly useless in the house. This will be the case untill Femtocells are rolled out.

My ex-colleague is very interested in the Femtocells now since he has no reception on mobiles in his house but unfortunately he will have to wait for some time.

Google search revealed an article titled Cellphone Signal Blocking via transparent window film (via engadget ... but for some reason the engadget site hangs ... so I have given actual cellular news link) which gives information on someone recently making these films.

Anyone aware of some more of these kinds of films? Any ideas on how much radiation-proofing they can provide? Should we all be having these once Femtocells are here and then just having controlled radiation in our house? I am interested in hearing opinions and suggestions.

Economic turbulence might effect funding of LTE and WiMax?

What a past few weeks we had in term of banking crises. There is no doubt that the recent turbulence in the banking sector has developed nervousness in everybody regarding the future we are going to have. I firmly believe that although the bail out has been carried by respective governments for the banks the turbulence will slip into the real economy before it starts getting better.

There is every possibility that in the near future the economic turbulence will have an impact on the funding of the projects. Some people may argue that efficient and good planning will take us through and hence the projects will not be affected. But the only question I am asking though is where the money will come from?

I do have a suspicion that as far as telecoms are concerned some of the major projects that will get affected in terms of funding will be LTE and WiMax.

We could we see analysts recalculating their projections for WiMAX and LTE soon in light of the struggling economy. There are many people out there who are putting a question mark in front of the plans that the major operators have got for LTE and WiMax. For example this week Forbes is questioning whether Sprint and the new Clearwire, which is expected to include Sprint's WiMAX network in the fold by the end of the year, can pull off a nationwide launch in a troubled economy. While Clearwire will have $3.2 billion from partners Intel, Google, Comcast, Time Warner and Brighthouse, it will need to raise an additional $2 billion to complete the network. These extra $2 billion would have been easy to generate may be a year ago but no in the current climate where there is already a shortage of money.

I am a firm believer that sometime these crises are good as this makes analysts, planning personal, designers and engineers realize to work hard and sort out the problems which they might have been complacently ignored in good times. Keeping in line with this thought, Clearwire could gain an advantage if the credit crunch lingers. Competitors AT&T and Verizon Wireless plan to deploy LTE and would likely freeze any deployments. For AT&T, such a deployment could be more than five years away as the operator doesn't seem to be in a big hurry to deploy the technology.

As I mentioned above sometimes these crises force the analysts to think hard and make sensible decisions.

For this reason I can now see that some of the companies have started taking HSPA and HSPA+ seriously which I though was always a good bet for fast mobile broadband till we get LTE. Some of operators and vendors have now reiterated their position that its HSPA and HSPA+ 3G network technology still had a lot of life left in it, and that LTE technology would not be rolled out for at least another three years and probably not on a large commercial scale for another five years.

Certainly the idea of throwing LTE on the backburner is not good for vendors that want to see operators invest in new technology soon. I am not saying this either but in the current economic climate operators and vendors can take HSPA and HSPA+ seriously do that the ARPU(average revenue per user) keep rising. If they are able to do so then the revenue generated can be used to fund the LTE/WiMax project. And once the economy starts rolling again which I’m sure will do in six months, money can pumped in heavily and vigorous plans can be drafted for LTE/WiMax.

The bigger question which arises is whether the operators can hook consumers on new technology in a tough economy. I believe they certainly can because HSPA and HSPA+ have lot to offer to consumers.

There are some analysts though which does not believe that that current economic climate will significantly impact communications usage and growth. They argue that communications are critical and relatively cheap compared to the real costly items for disposable income such as air travel, cars, home upgrades, schools, clothes, etc. They say communication revenues will probably increases and I think they might have a point here.

With the medicine provided by the governments of rich nations in terms of liquidity yet to reach to the patients, it will be a while before things start to look bit better. Let’s hope that the economy starts rolling again.

WiMAX publicity videos from Alcatel-Lucent

Alcatel-Lucent (ALU) has couple of interesting videos on youtube on WiMAX.

The first one is more of educational video showing how WiMAX is useful for everyone in everyday life:



Honestly, other technologies could be as useful as WiMAX. The other one is more of marketing presentation showing ALU offers on WiMAX.



Interesting.

LED-Fi: Replacement for WiFi Hotspots

Before we start, I have to confess that I made up LED-Fi. I was thinking more of LiFi but there is already a LiFi technology from Panasonic (not al all related ti this one though).
According to a post in cellular news, Lightbulbs Could Replace Wi-Fi Hotpsots in future:

­Boston University's College of Engineering is launching a program, under a National Science Foundation grant, to develop the next generation of wireless communications technology based on visible light instead of radio waves. Researchers expect to piggyback data communications capabilities on low-power light emitting diodes, or LEDs, to create "Smart Lighting" that would be faster and more secure than current network technology.

This initiative aims to develop an optical communication technology that would make an LED light the equivalent of a Wi-Fi access point.

"Imagine if your computer, iPhone, TV, radio and thermostat could all communicate with you when you walked in a room just by flipping the wall light switch and without the usual cluster of wires," said BU Engineering Professor Thomas Little. "This could be done with an LED-based communications network that also provides light - all over existing power lines with low power consumption, high reliability and no electromagnetic interference. Ultimately, the system is expected to be applicable from existing illumination devices, like swapping light bulbs for LEDs."

Little envisions indoor optical wireless communications systems that use white LED lighting within a room - akin to the television remote control device - to provide Internet connections to computers, personal digital assistants, television and radio reception, telephone connections and thermostat temperature control.

With widespread LED lighting, a vast network of light-based communication is possible, Little noted. A wireless device within sight of an enabled LED could send and receive data though the air - initially at speeds in the 1 to 10 megabit per second range - with each LED serving as an access point to the network. Such a network would have the potential to offer users greater bandwidth than current RF technology.

Moreover, since this white light does not penetrate opaque surfaces such as walls, there is a higher level of security, as eavesdropping is not possible. LED lights also consume far less energy than RF technology, offering the opportunity to build a communication network without added energy costs and reducing carbon emissions over the long term.

The ability to rapidly turn LED lights on and off - so fast the change is imperceptible to the human eye - is key to the technology. Flickering light in patterns enables data transmission without any noticeable change in room lighting. And the technology is not limited to indoor lights; its first real test may very well come outdoors, in the automotive industry.

I can understand how the downlink would work but not sure how uplink data transfer would work.

Similar technology using Light Bulbs has been available for some time. See this and this.

More defections to LTE camp

Nearly a year back, I blogged about Verizon defecting to LTE rather than going for UMB as it would be its natural evolution path. Last week Canada's Bell Canada and Telus Mobility announced plans to overlay their CDMA networks with HSPA technology by 2010 with an eventual move to LTE technology.

In a recent blog, I mentioned that operators moving from EV-DO to LTE can go via HSPA path or can also go for eHRPD. Fortunately, 3GPP saw that some operators may move to 3GPP camp and leave 3GPP2 due to economy of scale and much more variety of handsets, test tools, etc. Going back to the news item:

The move follows Verizon Wireless' decision to deploy LTE in the 700 MHz spectrum it won earlier this year. However, Verizon is skipping an HSPA deployment, choosing to continue investing in its EV-DO network that will likely complement the new LTE network for some time. Telus said the HSPA deployment would enable "a smoother transition to long term evolution (LTE) technology."

"Bell's transition to the global 4G LTE standard with a combined EV-DO and HSPA network path aligns us with more than 30 major carriers worldwide planning a similar move to LTE," said Stephen Howe, CTO with the operator. "This broad global technology ecosystem will mean a fast, efficient and cost-effective network transition to 4G LTE, and access to the broadest possible range of next-generation phones and data services."

Telus Mobility and Bell Canada both won spectrum in Canada's AWS-1 auction.

Which way: Femtocells or UMA?

Discussions are again resurfacing about which technology should be used to improve coverage; Femtocells or UMA. Honestly, I have not been a big supporter of UMA (and you dont have to agree with me) and earlier this year when Nokia raised doubts about the technology, i stopped following it completely. Kineto has been the biggest supporter of UMA and is still carrying the torch.

Kineto recently received over $15 million in investment from Motorola that it plans to use to increase its reach in UMA. Last month it had received investment from NEC. One of the reasons for the resurgence could be because the UMA technology has matured since being used for some time. T-Mobile has already rolled Hotspot @ Home using UMA. Also more phones are now available supporting UMA.

One of the drawbacks that will always be present in case of UMA is that special handsets will be required that would support WiFi as UMA is based on 802.11. This means more expensive phones and higher consumption of power leading to smaller battery lives. One more problem with UMA is the interference due to other ISM band devices and there are many technologies like Bluetooth, etc that are competing for the band.

The drawback in case of Femtocells could be that their price is still quite high as complete Node B + RNC functionality is generally available in a Femtocell and at the same time all the aspects have not yet been standardised. Along with these, Femtocells that use the same spectrum as that of the operator can cause interference with the Macro cell. This would in turn require very clever management of spectrum frequencies, etc.

A possible long term solution could be (but I dont see anyone agreeing to it right now) that phones with UMA technology become more common and a combined UMA + Femtocell equipment is rolled out by the operator. At the end user premises, depending on the strength of rf reception, the equipment can either use UMA or normal Femtocell functionality. If this idea is agreed upon, then there would still be couple of years before all interworking and other technological problems are ironed out.
