The iBangle is Gopinath Prasana’s vision of a future iPod where the devices have become darn close to becoming jewelry. If you factor in inflation and the cost of Apple products today - might as well call it jewelry because it’ll cost as much. I digress, the iBangle is a thin piece of aluminum (of course) with a multi-touch track pad. To achieve the perfect fit, a cushion inside the ring inflates to keep itself taught against your wrist. Unisex? Maybe.

LTE Advanced: NSN Proves relaying technology
Nokia Siemens Networks has broken new ground with another technological first: mobile broadband communications beyond LTE. Company researchers have successfully demonstrated Relaying technology proposed for LTE-Advanced, enabling an exceptional end-user experience delivered consistently across the network.
Completed in Nokia Siemens Networks research facilities in Germany, the demonstration illustrated how advances to Relaying technology can further improve the quality and coverage consistency of a network at the cell edge - where users are furthest from the mobile broadband base station.
Relaying technology, which can also be integrated in normal base station platforms, is cost efficient and easy to deploy as it does not require additional backhaul. The demonstration of LTE Advanced means operators can plan their LTE network investments knowing that the already best-in-class LTE radio performance, including cell edge data rates, can be further improved and that the technological development path for the next stage of LTE is secure and future-proof.
These performance enhancements have been achieved by combining an LTE system supporting a 2x2 MIMO (Multiple Input Multiple Output) antenna system, and a Relay station. The Relaying operates in-band, which means that the relay stations inserted in the network do not need an external data backhaul. They are connected to the nearest base stations by using radio resources within the operating frequency band of the base station itself. Towards the terminal they are base stations and offer the full functionality of LTE. LTE-Advanced is currently being studied by 3GPP for Release 10 and will be submitted towards ITU-R as the 3GPP Radio Interface Technology proposal.
The improved cell coverage and system fairness - meaning offering higher user data rates for and fair treatment of users distant from the base station - will allow operators to utilise existing LTE network infrastructure and still meet growing bandwidth demands.
The demonstration has been realised by using an intelligent demo relay node embedded in a test network forming a FDD in-band self-backhauling solution for coverage enhancements. With this demonstration the performance at the cell edge could be increased up to 50% of the peak throughput.

No LTE networks in UK before 2011
"I would say probably the end of 2010 at the very earliest," he told silicon.com. "Networks will be ready for rolling out - shipping in commercial quantities - next year and then the devices, we think, will start to come in 2010," he added.
Cunliffe would not give an estimate on how much a commercial rollout of LTE in the UK might cost. "People need to do more modelling around rollout costs," he said. "It's a new equation."
However, he claimed operators switching to LTE would reap the benefits of "total lower capex and lower opex" - provided they are willing to stump up the infrastructure cash.
However Cunliffe highlighted that any large-scale deployment of rival 4G technology WiMax would also require similar investment in infrastructure to that of an LTE deployment. "If you think about WiMax starting off as essentially a radio you need a much bigger ecosystem around it," he said.
"By the time you actually deliver a service, the operators still have to pay for the infrastructure that goes around it and they've still got their opex - their people costs and so on - so the WiMax piece - the radio piece - is actually a small piece of the equation. In terms of the maturity of the 3GPP ecosystem, it's well ahead of where WiMax is."
"The fastest being deployed in the UK at the moment is 7.2Mbps but our roadmap continues until 42Mbps. We can even see that it may be possible for the technology to reach as much as 80Mbps…so there is certainly a lot of mileage in HSPA…People maybe think that we've got to have LTE to get to the higher speeds but HSPA will go a long way before we need to get to LTE speeds."
Cunliffe added the top speed of LTE currently being demoed by Ericsson in lab conditions is 160Mbps and a drive test has reached a maximum of 154Mbps, with an average of 78Mbps.
What are the biggest hurdles to a UK LTE network being rolled out? Cunliffe believes they are timing - when operators will switch, especially those with significant investment in HSPA - as well as the inexorable issue of ROI: "Obviously there will be questions about return on investment," he concluded.

2009 is crucial for mobile vendors
With the new financial results predicting more economic woes, the early signs suggest that the majot telecoms companies might have a rocky ride ahead.
Most of the major vendors have already issued warnings for their handset sales. The news comes amid a week of profit warnings from other handset makers, including Research In Motion and Palm, as the handset market faces declining demand in the midst of a global economic slowdown. The research firm Gartner also released statistics about the smartphone market, which saw its weakest year-on-year growth since the firm started tracking the industry, and Nokia saw its share of the smartphone market fall to 42.4 percent, down from the 48.7 percent share it had a year earlier.
I remember during the year 2000/2001 when we saw the major telecoms burst, Nokia was still holding up and it produced some good results. I expect/expected similar this time as well from Nokia.
I was proven wrong when Nokia issued a market warning for the second time in less than a month, cutting its outlook for global handset sales, as the world's largest handset maker braces for a slowdown in the coming year.The Finnish giant now expects global handset sales to drop below the 330 million units for the fourth quarter it estimated on Nov. 14, and also said its estimate of 1.24 billion units for 2008 would have to be revised down. Those numbers were cuts from previous estimates. The company also said it expects growth to slow in 2009, with the market contracting 5 percent from its 2008 levels.
Indeed these figures coming out of Nokia presents bleak picture and make everybody nervous. It is very much evident by looking at the current climate that year 2009 will be challenging for telecoms industry.
However I still believe that companies like Nokia have a strong, enviable base to build on and I believe even in tough situation it will continue to strengthen its position on many fronts.
There is no doubt that in the face of a global economic downturn and weakening demand, handset makers and vendors affiliated with cell phone components are probably headed toward a large shakeup.
Companies with more high-end portfolios, including Apple, Research In Motion and HTC will be better positioned to handle any turmoil that would affect the handset market. All three have showcase devices that could help propel them through any choppy waters. In the case of RIM, there are multiple devices that could turn into large sellers, most notably the BlackBerry Storm, which Verizon Wireless has already launched.
However, others such as Motorola and Sony Ericsson, which cut 450 jobs from its North American headquarters earlier this fall, are in a weaker position. Motorola has said it is planning on focusing more on phones running on Windows Mobile and Google's Android platform to chart it back to growth, but said an Android phone would not be in the market until the end of 2009.
Most of the handset vendors will develop a strategy where they will concentrate on the market where the handset sales are still on the up. Europe has already been considered saturated in terms of mobile sales and hence this doesn’t come as surprise when Ovum declared in its report that Europe has become the first regional mobile market to be hit by the economic downturn.
But the the US mobile market has to date resisted the downturn and developing markets such as Latin America continue to enjoy double-digit revenue growth rates. Markets such as Latin America which remains overwhelmingly buoyant gives enough hope to vendors hence the expectation that they will be able to ride out the current financial crises.
I guess 2009 is going to be interesting.

SMS Rocks! Long distance shoulder amputation by text
David Nott, 52, a general and vascular surgeon at Chelsea and Westminster hospital, was working with the charity Médecins sans Frontières (MSF) in the town of Rutshuru when he came across the badly injured 16-year-old in October.
The teenager's left arm had been so badly damaged - either in an accident or as a result of the fighting between Congolese and rebel troops - that it had already had to be amputated. But the flesh and bone that remained had become badly infected and gangrenous.
"He was dying" said Nott. "He had about two or three days to live."
The doctor realised the boy's best chance of survival was a forequarter amputation which requires the surgeon to remove the collar bone and shoulder blade. The only problem was that it was an operation Nott had never performed. But he remembered that one of his colleagues at home had carried out the procedure.
"I texted him and he texted back step-by-step instructions," he said.
"Even then I had to think long and hard about whether it was right to leave a young boy with only one arm in the middle of this fighting.
"But in the end he would have died without it, so I took a deep breath and followed the instructions to the letter."
Such an operation, if performed in the UK, would require careful planning with every sort of modern medical product on hand if things went wrong.
But in Congo Nott had just one pint of blood and an elementary operating theatre.
Despite the basic conditions, the operation was a success and the teenager made a full recovery.

Nokia to power Smarter Homes
Until now, solutions to home automation challenges have been sought through the development of better sensor networks. Although they are, of course, very important parts of new smart home solutions, no single sensor network technology can solve the challenges in this field. Z-Wave, ZigBee, and KNX are all attempts to define a common command language for home networks. So far, there has not been a clear winner in the battle for the de facto standard of home networks. Hence, it can be assumed that a future home will use several different technologies.
The whole Nokia solution consists of four main components:
1. The heart of the solution is the Nokia Home Control Center which is built on top of standard gateway architecture.
2. Two most important control nodes are the mobile phone and web browser.
3. The back-end server architecture ensures a seamless and secure link between a mobile device and the home gateway and also makes possible updating and upgrading software easily.
4. The partner devices. In addition to the components that Nokia is providing, the value for the end customer comes from the integration of different third party devices and systems under the control of one user interface.
It will be possible for example to monitor and control electricity usage, to swich devices on and off, and monitor different objects, such as temperature, camera, and motion. On one hand, Nokia Home Control Center can be used as WLAN gateway. On the other hand, the platform covers everything from a basic security solution to a more sophisticated heating control system. Users are free to build a solution that fits to their needs and expand it when ever they want.
"We are delighted to have secured a world-leading technology partner in Nokia for our range of smart home energy products. Our aim is to offer innovative and affordable energy-efficient solutions for every household that are simple and convenient to operate", said Carolin Reichert, Head of New Business at RWE.

Is Urgency for LTE growing?
In this blog I would like to carry this thought forward. With more and more giants moving into LTE camp as compared to WiMax there is a sense that LTE will soon pick up. Recently I have been sensing that thee is some urgency out there in regards to LTE development. Vendors and operators are pushing to the extent to get the technology out as soon as possible.
As I mentioned some time ago that I am really a big fan of HSPA+ and I once again say that till LTE arrives, HSPA+ can serve the purpose up to an extent.
As we already know that T-Mobile recently tested LTE and this really gave a push to the technology. There are lots of 3G operators now who share T-Mobile’s LTE aspirations although reaching to these LTE or 4G goal will not be straight forward. Lot of urgency for LTE also depends on what the operators do with HSPA+. Some of the operators might go for HSPA+ and hence wait longer before deploying LTE.
It’s quite interesting to see that operators such as T-Mobile are going for LTE whereas some operators currently staying away from LTE and hence going to launch HSPA+. Evidently LTE as it still a long way away from mass market maturity hence it’s going to be difficult for some operators to stick to its guns for LTE. I guess this also is one of the major factors contributing towards the urgency for LTE.
Currently the three big operators pushing LTE development are China Mobile, NTT DoCoMo and Verizon wireless. T-Mobile believes it is every bit as aggressive as those three operators and should be included in that list. The evidence of this is the urgency shown by T-Mobile when it tested LTE recently.
T-Mobile believes that LTE is suited in the long run, i.e. till 2020, to be the technology that you can consolidate all technologies onto -- GSM and UMTS.
Another operator showing urgency toward LTE is the world's largest mobile operator in terms of subscribers, China Mobile. China mobile plans to begin testing LTE soon where only the lack of chipsets are holding back its plans at the moment. Many telecom experts believe China's operators will essentially leapfrog 3G as the government continually delays tenders and opt for a 4G deployment like LTE.
At the same time as I mentioned some of the operators might decide not to get sucked into HSPA+ and rather push for LTE. This urgency for LTE is certainly demonstrated by T-Mobile once again when it announced it will not deploy HSPA+. The operator has indicated that to boost its mobile broadband throughput it will instead invest in LTE thus stepping up the pressure on equipment vendors. However T-Mobile might deploy HSPA as long as no hardware upgrade is required.
The above developments is allowing some to accuse T-Mobile of attempting to force equipment vendors to place greater emphasis on the development of LTE as against further refining HSPA+. Given that China Mobile, DoCoMo and Verizon Wireless have each made aggressive statements regarding their intent to push forward with LTE, then those interested in such plots have more to go on.
However, there is a question as to whether these operators, including T-Mobile, can wait for LTE, especially given the marketing hype around mobile broadband offers.
There is no denying that the above mentioned operators are aware of this situation and hence I guess this is main reason why they are showing immense urgency towards LTE.

Femtocells as the starting point - more info
One idea is to use LTE initially as an access point rather than a full standalone network, which would bypass all the difficulties and delays that may happen in developing the core network for this technology. Here femtocells, picocells or GAN dual mode solutions could help operators to achieve this goal. As well as the time to market advantage, operators will also have a good opportunity to test LTE access networks and their business case for it before engaging in any wide scale network rollouts. This will obviously help them to minimize risks while giving them enough time to get their networks more stable and ready for the challenge.
Several chipset and hardware platform manufacturers have launched products for LTE femtocells, including Picochip and Agilent. The upcoming 3GPP femtocell standard is expected to provide compatibility for LTE femtocells and mobile operators are expected to announce their LTE strategies in 2009. Informa Telecoms & Media expects that the majority of mobile operators – especially those that have invested heavily in 3G – will incorporate femtocells in their LTE strategies either for business case validation or for selective, incremental capacity upgrades for their mobile networks.

SDR: Today and Future
The key benefits of SDR are as follows:
- Reducing the Bill Of Materials (BOM)
- Lower development costs
- Facilitate better reuse of intellectual property (IPR)
- Possibility to upgrade products already in the field
- Enabler of the Cognitive Radio vision
- Flexibility is the key for baseband. Some of the common signal processing blocks may not be reusable. This means that though some protocols can easily be defined for a particular baseband, others may not be possible for that baseband. Good progress is still being made though on this front.
- Reconfigurable RF is some way away, further down the road.
- The biggest challenge is the antenna interface for which no proper solution exists. Some solutions being worked on right now include MEMS based solution, Carbon nanotubes, Special ceramic materials, etc.
Cognitive Radios are defines as: A radio that can autonomously change its parameters based on interaction with, and possibly learning of, the environment in which it operates. Through appropriate radio resource management, such a cognitive radio should make flexible and efficient use of network/spectrum resources.
- Opportunistic Radio: A radio that co-exists with other systems using the same spectrum. E.g., White Space Devices
- Smart Reconfigurable Radio Systems: A radio that makes flexible and efficient use of network/spectrum resources across heterogeneous environments. Seamlessly roaming possible on different networks, countries, frequencies, etc. It requires true paradigm shift i.e., spectrum liberalization
