Complex LTE IPR System
Markus Münkler, Vodafone Group R&D spoke about IPR Regime for LTE @ LTE World Summit, Berlin
Progress since 2005
•ETSI has improved visibility of standards essential IPR across its membership
•NGMN Ltd has produced indications of the total royalty burden of candidate technologies LTE & WiMAX
•Placed IPR royalty rates in the middle of the next generation mobile economy debate
•Raised the IPR discussions to the attention of the EU and other regulatory bodies
•Built a legally sound platform of trusted collaboration among technology stakeholders
Interim conclusion
•IPR transparency has improved among engaged industry stakeholders
•However, new challenges have emerged from outside the technologydevelopers
•Therefore, IPR royalties remain a stumbling block on mobile technology developments

Firefly for British Kids
A new mobile designed for kids, the Firefly phone, is set to launch in Britain later this year, but the four year-old target audience already has adults in uproar.
The Firefly phone, a tiny handset for toddlers which packs just five buttons including “Mum” and “Dad” keys, and extensive parental controls, has been a hit in Ireland, and it set to go on sale in the UK later this year.
But the phone has caused concern amongst parental groups, with Aine Lynch, chief executive of the National Parents Council going so far as to question “where parental responsibility is going”.
“Why would kids need to be contacted by mobile phone? Why are they not in the care of their parents, teachers or supervisors?”, she said.
Indeed. Still it could be amusing to see nursery lessons interrupted by the Nokia ringtone, and we’ve seen tweens rocking iPhones before so perhaps a controlled environment is better than nothing at all. And certainly more appropriate than the Penis phone. We’ll let you know if the Firefly phone leads to the downfall of civilization or not.
Surprisingly this phone was announced couple of years back, I cant see why its taking so long.
The French have already said no to such phones but we Britishers are much more tolerant (in all aspects ;) so you may find children using them soon.
Tim Dowling from the Guardian argues against it:
There can be no earthly reason why a child of four would need a mobile phone, but there must be dozens of reasons why it shouldn't have a Firefly. Here are just a few:
- It is not possible to conduct a fruitful phone conversation with a four year old, as you will know if you have ever tried.
- Four-year-olds rarely, if ever, have information to impart of such significance that it cannot wait until they are five.
- A Firefly costs £60. Without a sim card.
- Your child should always be in the company of a responsible adult who has a phone you didn't have to pay for.
- A four-year-old with its own phone will spend all day attempting to contact Pocoyo.
- Four-year-olds never hang up.
- 52% of children between the ages of five and nine already own a mobile. Chances are you will have to buy the child a phone next year anyway, and they won't want a pink toy that doesn't do YouTube.
- If you don't know where your four-year-old is, there's no point in ringing him. He doesn't know where he is either.
- For much less money you can get tiny T-shirts with your phone number and the word REWARD printed on them.
- Four-year-olds are enough trouble as it is. The last thing we want to do is give them is the means to organise.

Operators give Femtocells Thumbs up in Femtocells World Summit
"We will expand that into a marketing trial of the AT&T-branded 3G Microcell, which will be open to customers through our AT&T stores ... in a handful of cities,” said Gordon Mansfield, AT&T's executive director for radio access network delivery, speaking at the Femtocells World Summit in London. "We're on track for a full national launch by the end of 2009."
He also said the carrier was exploring ways to expand the femto opportunity beyond simply selling standalone home base stations that offload cellular backhaul from the macro network and boost bandwidth for cellular users. For instance, integrating a femto into other devices in the home.
Meanwhile, Vodafone UK 's surprise femtocell service launch announcement yesterday won't force T-Mobile International AG 's hand to launch a rival service in the U.K. or in any of its markets.
The German giant is sticking to its femto guns and does not feel compelled to take on the largest mobile operator by revenue with a commercial home base station service of its own, simply because Vodafone was first to market in Europe.
"We won't be pushed by that announcement," said Klaus-Jürgen Krath, T-Mobile's senior VP of radio networks engineering, speaking on the sidelines of the Femtocells World Summit in London today. "Let's see how they do in the market...
"There is not any firm launch plan that I can disclose now," he added.
T-Mobile has been busily testing and investing in femto technology for the last few years, but the operator maintains that there are still technical and marketing issues that need to be resolved before a consumer mass market solution is possible.
T-Mobile is a strategic investor in access point vendor Ubiquisys Ltd. and femto chip startup Percello Ltd.
According to French mobile operator SFR , France is a tough market for femtocells.
And one of the issues that makes the country extra special in Europe is the growing public concern about the health risks from cellular antennas and handsets, according to Guillaume de Lavallade, director of network marketing at SFR, who was speaking at the Femtocells World Summit in London.
WiFi hotspots have been disconnected in public libraries; there have been court actions to prevent the installation of cellular masts or have them removed when they're close to schools or homes; and the national government is investigating the health risk associated with masts and handsets, explains Lavallade.
"Introducing femtos in France in this environment is raising these questions," he says.
You can explain that the emitted power of femtos is 10 times less than that of WiFi, comparable to a DECT phone, and that 3G handsets emit less power when connecting to the femto than on the macro network, or that a network based on a femto architecture generates less power than a macro architecture, he says.
"It's difficult for an operator to take those facts and figures to the consumer," he says.
SFR has been trialing a femto from Ubiquisys Ltd. , which was spotted on a French Website recently.
SatNav need an integrated solution
But imagine that you have a navigation tool or gadget which acts as your own personal travel guide. It has satellite navigation, so when you get into your car it can direct you to where you want to go. It can choose the most carbon-efficient route and make sure you avoid crowded town centres, traffic jams and road works. It can let you know where the next petrol station is, and whether there is an Italian restaurant near your hotel. Before you arrive you will know which of the town car parks have spaces left. And when you've finally parked the car, take your guide with you and it will direct you, on foot, to your final destination.
For anyone who has found themselves stuck in a traffic jam, or has been unable to find a car park in a busy town centre, or has got lost on foot, it sounds too good to be true. Yet the technology to make it happen is already here. So why aren't we all carrying such a device in our pockets?
The question which then arises is that why the universal travel widget isn't at hand. One of the reasons for that is that several different worlds have to collide and co-operate. First of all there is a massive competition together with a huge confusion regarding the platforms in which such device can be built on. To start with we have got proprietary platforms like TomTom and Garmin, and then we've got the at least five major mobile phone operating systems.
The obvious competition between these different platforms has instigated some suspicion but apart from this the mobile companies also have yet to ¬recognize the potential of phones as navigation devices.
You can argue that many mobile phones are already GPS-enabled but in my opinion this doesn't necessary make them effective at navigation. For instance try using your blackberry as a navigation device and you’ll find that battery has quickly drained out. The mobile phone world is slowly coming to terms with the needs of navigation on mobiles, such as better ¬battery life and bigger screens. Infact GPS alone doesn't offer the precision needed to navigate pedestrians, and so to be useful needs to be combined with another positioning service such as Wi-Fi. This has been done with the iPhone, for example.
The accuracy and granularity of data used in satellite navigation systems is very critical and has to be improving all the time. The real problem lies in integration where the data needed to provide a coherent information service to a navigation device is held by different organisations in a number of different places. While there are companies that are providing some location-based information such as information about ATMs, speed cameras, train times or tourist sites but there is no company in my knowledge that offers everything.
Combining all the information and hence provided through a single device at a one point of time that information isn't going to be easy. The challenges which lies in this are not solely technical for example there's a data aggregation problem to bring it altogether, including highway changes, updates from local authorities and then there's a physical problem in gathering all that up.
Even if the above issues are solved there is still a major part of the problem which is revenue. How one would make money out of integrated Satnav device? There's a difference between what can be done technically and a viable ¬product that can be sold. How do you turn that into something that fits in a business model?"
Organisations that have valuable data rarely want to give it away for free, licences to reuse companies or government’s mapping data commercially are expensive. Similarly, there is no incentive for the Highways Agency or local authorities, for example, to share information about traffic conditions. Even the government website Transport Direct, which provides free up-to-date transport information, has restrictions on the integration of its content with other services.
So now you may realize that how trying to highlight the potential of the problem. It’s a mammoth task to bring all the above information together into one place as everyone wants their pound of flesh because everyone has developed their own data infrastructure and it's just very difficult to get them to agree.
I certainly hold the opinion that inspite of all these hiccups the demand for an all-in-one travel service almost certainly exists. People simply really want a so called integration or integrated device which can work across different ¬locations i.e. home, work, on the move etc.
It’s evident from the above facts that the emergence of a ¬genuinely integrated solution will depend on a government initiative to force public sector organisations such as Highways Agencies, Transport for London and local authorities to collaborate, or on a private sector organisation taking a ¬commanding lead in terms of developing location technologies.
Google is one such company which is creeping up with a whole series of ¬initiatives that are steadily putting the pieces in place. Best example for this is Google Maps which are now readily available on all mobile platforms and is integrated with traffic data from the Highways Agency. Not only this, the Google Maps application interface (API) allows third parties to build their own applications as well.
Google, no doubt is leading with an example in terms of it’s initiatives towards serving the customers in best possible way. Google certainly knows what the customers want which I believe a mini innovation in these current economic climate.
Location has always been such an absolutely fundamental framework for our lives, and we inevitably must embrace tools that allow us to manage that. I envisage a society in 20 years' time revolutionised by the ability to know all the location based information.

Mobile Phones too complicated
The majority of UK consumers see mobile phones as “overcomplicated and burdened with unnecessary features” according to a survey released today.
The research, conducted by mobile recycling specialist Fonebank showed 60 per cent of the 1,000 respondents find current mobiles too complicated to use. A third also cited “simplicity of use” as an important factor when choosing a new handset.
The survey comes at a time when new smartphone releases are dominating the headlines such as the N97 and iPhone 3G S.
Mark Harrison, director of Fonebank, said in a statement: “People think they care about ‘pixels’ or ‘megabits’ when in fact they just want mobiles that are easy to use. Calling and texting remain the primary functions of mobiles, with web surfing, emailing and music capabilities relatively unimportant.”
Report on 'Femtocell Applications Live' at Femtocells World Summit
There were 12 companies showing their demo. Unfortunately I was not able to capture the complete details but here is summary of my understanding (and notes and photos).
Before we proceed further, I should also mention that Femto Forum launched Services Special Interest Group (SSIG) whose main task is to to develop a framework that will simplify the development and deployment of femtocell applications.
Demo 1: IP Access
IP Access showed couple of demo's. The first being Facebook Virtual Fridge Notes Applications and the other Femto-enabled Connected Home Applications. There was some problem with the microphone and also CDMA like interference problems (if someone in the room is shouting, everyone starts shouting and the noice level increase drowns out the useful info) so I diddnt catch the second demo very well.
Demo 2: Motorola
Their demo included Mobile Presence where, when the mobile reaches the Femtozone, different actions are triggered. They also showed how to remotely control TV and other applications through mobile when Femtocells are present.
Demo 4: Ubiquisys, Intrinsyc, Mobica
Demo 6: Airvana
You can also synchronise the Digital Picture frame to your mobile so that whenever the phone comes in the Femtozone, the pictures are uploaded to display automatically.
Demo 7: Alcatel-Lucent
There was a video demo showing how useful Femtocell can be in daily life. For example a person is leaving home but has forgotten to close windows, so he gets a notification just when he is locking the door. Also if some friend comes to your house while you are shopping outside, you do not have to rush back. You can remotely unlock your door for him.
Along with the demo's mentioned above, LG-Nortel was showing their WiMAX Femtocell solution.

ALU and Vodafone hit the first goal in Femtocell World Summit
Vodafone has announced the Femtocell World Summit today that its launching the first commercial Femtocell based service on the 1st of July.
Vodafone 's move is important for the sector not because it is supporting any groundbreaking applications in the first stage - the launch is firmly focused on improved indoor signals - but because it quietens the major source of nervousness about femtos, that they are not sufficiently tried and tested for mass consumer roll-out. This has led some suppliers to argue that operators will not move beyond trials for at least another year and possibly longer, delaying the payback for vendors and other involved parties.
Vodafone is understood to be using femtocells from Alcatel-Lucent, probably the most prominent tier one wireless vendor to offer its own devices rather than badging those of a specialist supplier. ALU's products run on the architecture of UK-based picoChip, which also supplies the silicon for ip.access and others. Live roll-outs by Vodafone and AT&T will be valuable for the credibility of the whole segment, and for the sustainability of the specialist start-ups like picoChip.
Samsung flexes muscles in CommunicAsia 2009 with Jet S8000
Samsung, the world’s second biggest handset maker, opened its mobile applications storefront in February and has been running a developers’ forum since last year.
Apple, RIM and Android have already opened up app stores, selling directly to consumers. No carrier has launched an app storefront, although China Mobile is set to launch in September and Vodafone by year-end.
Samsung also unveiled the Omnia II (I8000), OmniaPRO series (OmniaPRO B7610, OmniaPRO B7320) as well as the OmniaLITE (B7300). Featuring cutting-edge technology, these mobile devices will strengthen Samsung’s leadership in the smartphone market.
The new Omnia smartphone line-up follows the success of the very first flagship ‘Omnia’ phone, Samsung’s milestone Open OS model which was launched at CommunicAsia last year.
With the introduction of its new Omnia smartphone series, featuring diverse functions for a wide range of user needs, Samsung truly offers a variety of smartphones for everyone - from those seeking entertainment to business users to light users.

Book Review - Femtocells: Opportunities and Challenges for Business and Technology
Femtocells: Opportunities and Challenges for Business and Technology
by Simon Saunders, Stuart Carlaw, Andrea Giustina, Ravi Rai Bhat, V. Srinivasa Rao
This is not a very thick book with just 252 pages. Someone may say that there is not much to write about Femtocells. I say that you can fill couple of thousand pages not with much difficulty on Femtocells but it is important to seperate the useful things that everyone will be interested in and just keep that in the book. When I told a colleague that a new book on Femtocells is out, the first question he asked me jokingly is does it cover 'Zero Touch'. The answer is, yes it does ;)
It starts with the very basic what Femtocell is and what its not, goes on to talk about the types, the user benefits, Attributes, applications, challenges, etc.
It then goes on to examine the background for small cells, placing femtocells in the context of the history of other solutions for in-building service and explains the market and technological factors which have made femtocells a compelling proposition. It also addresses market issues, covering the benefits and motivations of femtocells for operators, the key market challenges, business case analysis and forecasts for the take-up of femtocells.
Chapter 4 covers radio issues for femtocells, including the requirements and methods for interference management between femtocells, femtocell RF specifications and health issues. There is a very good table that lists out the potential problems of using Femtocells.
The next chapter covers the network architecture of femtocells, particularly the interfaces and protocols for integrating femtocells with the operator network across the Internet and the way in which the various options differ between standards families. This chapter also introduces the 3GPP based Iuh interface for Home NodeB's. There are other interesting Femto architectures like the CDMA based, WiMAX based, GSM based and LTE based covered in this as well.
Then there is a chapter on the Management of Femto's that describes the requirements and approaches for provisioning and managing millions of femtocells in an efficient and scalable fashion. It explains about the TR-069 data structure and management protocol.
Chapter 7 is dedicated to the very important topic of Security. It explains the security aspects of femtocells from a customer and operator perspective, including analysis of the potential threats and solutions.
Chapter 8 covers the standards for femtocells across the main mobile standards families, namely 3GPP, 3GPP2 and WiMAX Forum. It also introduces the industry bodies who are playing important roles in the introduction and proliferation of femtocells. There is a list of all the 3GPP standards for the Home NodeB and Home eNodeB.
Finally there are chapters on Regulation (including lawful interception, etc.), Implementation Considerations (showing refrerence designs, etc.), Business and Service Options (with examples of scenarios and service options) followed by a Summary.
You can learn more about this book from its official website at http://www.femtocellbook.com/
There are lots of things I may not agree on and there are things i would like to argue about but overall It looks like an interesting book especially for people who either work in or follow femtocells area. With the femtocell information scarce at the moment, this book is like information goldmine for readers. I would be interested in hearing from any readers about their opinion of this book.
Vodafone's Lecture series on Mobile Telecom and Networks
This compilation brings together the transcripts of the third of a series of lectures on the subject of Mobile Telecommunications and Networks. The lecture series was established by The Royal Academy of Engineering and Vodafone to celebrate the enormous social and economic benefits that mobile communications have given us – a success story brought about and maintained by excellence in communications engineering. The three lectures in this series were given over the period between March 2008 and February 2009. All three were exceptionally well attended and generated enthusiastic and lively debate and discussions.
The series was opened by Professor P R Kumar, Franklin W Woeltge, Professor of Electrical and Computer Engineering, at the University of Illinois. His lecture addressed the converging worlds of communications, computation and control – described through infrastructure - free wireless networks, and illustrated with fascinating films of model systems created at the University of Illinois.
The bedrock of all wireless communications systems is radio frequency spectrum, and this was the subject of the second lecture, given by Professor Linda Doyle of the Department of Electronic and Electrical Engineering at the University of Dublin. She entered into the debate of how one should allocate and manage spectrum, covering approaches from classical ‘command and control’ to dynamic ‘grab what you need when you need it’. Her lecture gave rise to the most lively debate we have had during the Questions and Answers sessions.
Most lectures on mobile communications nowadays are concerned with subjects like broadband access, convergence, mobile widgets or the phone as a computing device, so it was refreshing that in the final lecture of the series Professor Peter Vary of the University of Aachen returned to basics – voice communications. In a fascinating lecture he covered the history of and contemporary research on speech coding for mobile communications, providing great insight into what is the most important function of the phone.
The transcript is available here.

New Text Message: "Feed me, I am Thirsty"
Technology that lets plants send text alerts when they're running dry may someday reduce overwatering, says a Discovery Channel report. A chip about the size of a clip-on earring can be attached to a plant leaf and linked to regular cell-phone networks, sending a text message when it's time to irrigate. Watering only when necessary could save water and energy, especially in the arid West. A company called AgriHouse is marketing the chip, which is based on technology developed by NASA for long space trips.
Water in the open spaces of the west is valuable, but it's virtually worth its weight in gold in outer space. The original cell phone for plants was developed years ago by scientists working with NASA on future manned missions to the moon and Mars.
"You need plants on future space missions," said Hans-Dieter Seelig, a scientist at the University of Colorado at Boulder who worked on the original NASA project.
"They take out waste carbon dioxide, produce breathable oxygen, and the astronauts can use them as food," said Seelig.
During their research, the NASA scientists concluded that astronauts wouldn't be able to take anywhere near enough food and supplies for an estimated two-year mission to Mars. The pilots and Ph.D.'s selected for the trip would have to spend most of their time as celestial subsistence farmers.
To reduce the amount of time and supplies necessary to grow crops, scientists clipped sensors, wired to a central computer, to plants so astronauts would know exactly when and how much water to give them.
During the initial NASA tests the scientists were able to reduce the amount of water necessary to grow plants by 10 percent to 40 percent.
You can see a Video on AgriHouse website here.
A similar approach was also demonstrated earlier this year.
Interactive telecommunications researchers designed a soil-moisture sensor device that can allow a house plant to communicate with its owner. The device can send short messages to a mobile phone or, by using a service called Twitter, it can send short messages to the Internet. The messages can range from reminders to water the plant, a thank you or a warning that you over- or under-watered it. To communicate, probes in the soil emit electric waves. A voltage level based on the moisture content is sent through two wires to a circuit board that compares the optimum moisture level with the current one. A local network receives this data and allows the plant to send a message through the device.
All this is possible through a new system called Botanicalls, which is developed by Interactive Communications researchers. This system allows your plants to send text messages to your cell phone or even on internet. The plants will know when they need water and they will let you know, or, if they have been watered, they will just thank you. More, they will tell you if you put enough water or they need more.
So how Botanicalls works?
Some sensors are placed in the soil with the plant, and they measure the level of moisture. These sensors send a signal to a microcontroller to determine if the moisture is low or high, or if water has been added or not. Based on that, the sensors can send a wireless signal to an internet connected computer than can send a prerecorded message to the plant owner. Messages include “thank you” when the plants are watered, or warnings if the water is too much, or the plants haven’t been watered and they need water.
You can see their video here.

SMS: Information, MisInformation, Emergency and Spam
The other day someone pointed out that the number of SMS send per day globally is 2 Trillion. I said, surely this cant be true. The population of the world is somewhere around 7 Billion mark. If we assume that everyone uses the phone and sends 1 message per day than that is still 7 Billion messages, 2 Trillion cant possibly be true.
According to a post earlier, 1 Trillion messages were sent in 2008, compared to 363 Billion in 2007. Thats between 3 and 3.5 Billion per day. We may have to wait probably just couple of years before we see 1 Trillion messages per day (assuming the Networks can cope with this amount of SMS's). The reason for sharp rise in the number would be due to various factors.
The first reason being Spam. China is already facing SMS Spam problems. Its becoming such a nuisance that the operators are considering limiting the number of SMS to a max. of 200 messages per hour and 1000 per day. On holidays, 500 and 2000 respectively. I am not sure if Spammers use phones, rather there are many websites allowing bulk messaging facilities. Many companies are also offering power texting facilities that allows big bundles for minimal pricing. The average price being 1 cent per SMS or even cheaper.
Another reason that we should not forget is the introduction of many QWERTY phones that is making life of texters easier. There is some debate as to whether its having good or bad impact on the teens but I think its the health problems we should be worried about more than anything else. Its just matter of time when you get a new phone, there will be a caution note saying: "Caution: Text messaging can seriously harm your health. It can cause sore thumbs, cause sleeping disorders, anxiety and in some cases depression. Please click on I Accept if you would like to use it at your own risk" :)
Deciphering teen text messages is an art in itself. I blogged about it earlier but things change faster than you can anticipate. LG have launched a DTXTR service that can help you decipher your teen text messages. I tried few codes and it failed miserably. I suppose for these kinds of services, one more thing you need is to know the location of the users. Same code word can mean different thing in different countries/states. Webopedia has a very detailed list of these abbreviations.
Finally, I have always wondered why emergency services dont allow SMS. If I am in a bank being robbed, its safer to send a text rather than call and speak to an operator. Good news is that, its already being tested in the US. This should complement the eCall feature in future.

Dictionary of LTE Acronyms
SMS good or bad for the teens?
When SMS was invented it was though that it’s an ideal way of communicating with somebody in short and that too cheaper than the actual call. What really picked up in the field of SMA was an easy way of communicating with somebody whilst busy doing something else. SMS specially has become a big hit the teens of today and they love every bit of it.
Teenagers worldwide, these days are sending thousands of text messages per month. While one might be tempted to imagine that it is not a problem due to the availability of unlimited text messaging plans, the issue here is hardly a financial one.
Teenagers have taken the texting to a different level where they depict a brilliant example of multitasking. Albeit concerns are growing over issues such as how excessive text messaging threatens proper sleep, as many teenagers text message late into the night. Or as I can imagine, probably even waking up in the middle of the night to check and reply to new text messages.
In the last five years itself text messaging has gained significant momentum with the teenagers worldwide and the pertinent question here is whether such use of mobile devices will create a generation of adults addicted to perpetually buzzing or beeping mobile gadgets. This could produce a generation that has trouble sitting still and focusing on the task at hand.
There is no doubt it’s easy to find a way of getting distracted especially when you are teen. Imagine you are busy doing something important and you phone beeps thus indicating of the arrival of a new message. In this scenario 99% of the teens including some adults as well will definitely be paying attention to the new SMS and mostly replying for it as well.
In my opinion SMS is like any other things to play for the teen which basically keep them interested and involved. Any fun which is easily and readily available to the teens will definitely attract them no matter which generation they belong to. So what can be a boon for some can be bane for others. What is your opinion on text messaging?
