Pomegranate concept mobile: With video projector, live voice translator, harmonica, coffee maker, shaving razor, etc

The Pomegranate NS08 is a concept (fictional - though some people refer to it as a hoax) phone that promised amazing stuff until you dig deep and realise that its just an idea to market Communication Nova Scotia's Come to Life program. Check out the Youtube clip for the complete advertisement:

The following is from Wikipedia:

The Pomegranate phone is the latest campaign from Communications Nova Scotia's Come to Life initiative, the place-branding program of the Government of Nova Scotia. Communications Nova Scotia has been criticized by some for spending $300,000 on the ad campaign, though the website received more than 1,100,000 visits from 201 countries/territories since its launch on September 30, 2008, and they are considering it to be very successful.

HSPA finds success with Mobile Broadband Growth

Another GSA report titled "Mobile Broadband Growth - Reports from HSPA Operators Worldwide". As the name suggests, this contains report from different operators on their Mobile Broadband revenues growth.

Some interesting bits from the report:

• According to a report from AdMob, smartphonedata traffic grew 193% year-over-year in the month of February 2010. Smartphonesaccounted for 48% of its traffic in February 2010, up from 35% the year before. AdMobattributed this primarily to iPhoneand Android traffic.
• Deutsche Telekom CEO René Obermann is expected to double revenues by 2015 with €10 billion coming from mobile data traffic. Obermann said it would double the number of 3G smartphonesin the network to around 8 million by the end of 2010
• A recent report by In-Stat, stated that mobile broadband is now the second-largest access technology behind DSL, making up 18% subscribers
• Telia Sonera reported that the strong demand for mobile devices, including mobile broadband and Apple iPhone™, continued. Mobile data traffic in Nordic and Baltic operations increased close to 200% while the number of mobile broadband subscriptions rose by more than 60% during 2009.
• AT&T reported that Text messaging grew 50% YoY and picture messaging grew 130%
• According to IDC's Worldwide Quarterly Mobile Phone Tracker, vendors shipped a total of 54.5 million units Q4 09, up 39.0% from Q4 08. Vendors shipped a total of 174.2m units in 2009, up 15.1% from the 151.4m units in 2008. Converged mobile devices accounted for 15.4% of all mobile phones shipped in 2009, up slightly from 12.7% in 2008
• The number of people subscribing to broadband internet services in Australia grew rapidly with wireless broadband and 3G mobile services continuing strong growth in 2009, according to a new report by ACMA (Australian Communications and Media Authority). 3G now accounts for more than 50% of all mobile subscriptions, an annual increase of 44%. Internet subscriptions reached 8.4 million in June 2009, compared to 7.2 million in June 2008. Broadband subscriptions increased from 5.66 million to 6.72 million in the same period, with wireless subscribers gaining 162% to 2.1 million
• Vodafone's Data traffic has risen 300% in the past two years. Data now represents 11% of all European service revenues. Smartphones represent 20% of handsets sales. Around 40% of the company's European 3G/HSPA networks now support 7.2 Mbps. In the coming 6 months, Vodafone plans to upgrade 20-25,000 sites across Europe to HSPA+
• UK consultancy firm, Coda Research Consultancy, has predicted that mobile data consumption in the US is set to reach 327,000 terabytes a month by 2015, indicating a 40-fold rise in mobile data consumption over 5 years
• Mobile data traffic from PC modems and routers is forecast to increase 4-fold between 2010 and 2014, according to a report by ABI Research. 2,000 petabytes of data will be sent and received in 2010, a figure that will rise to about 8,000 petabytesin 2014
• Semiannual US wireless industry survey was released at CTIA in March 2010 revealing that wireless service revenues totaled $77 billion for the last half of the year. The real growth is coming from wireless data services -mobile Web, text messages, and other non-voice services. In the latter half of last year, revenue for wireless data service totaled > $22 billion, nearly a third of overall wireless services revenue and up 26% YoY. Steve Largent, President and CEO of CTIA, said in a statement. "Mobile broadband will increasingly play a vital role in people’s lives."
• A new study by Juniper Research has forecast that more than 1 in 10 mobile subs will either have a ticket delivered to their mobile phone or buy a ticket with their phone by 2014, representing a five-fold growth over the next five years.
• Strategy Analytics recently forecast that the number of active mobile broadband subscriptions worldwide is expected to rise to around 1.3 billion by 2014
• ABI Research announced that shipments of mobile broadband-enabled consumer products, which includes e-book readers, mobile digital cameras, camcorders, personal media players, personal navigation devices and mobile gaming devices will increase 55-fold between 2008 and 2014 with total shipments reaching 58 million units per year in 2014

GSA report on Evolution to LTE

Global mobile Suppliers Association (GSA) published a report on "Evolution to LTE" which is available on their website here to download.

The report starts with the need for LTE and emphasises its importance with regards to the Mobile Broadband take off. It goes on to encourage the operators to embrace LTE and lists the operators that have committed to LTE roll out.

As of April 2010:

• 64 networks in 31 countries have committed to LTE network rollout.
• Upto 22 LTE networks would be in service end of 2010
• 39 or more LTE networks will be in service end of 2012

Spectrum is another area of focus of this report. Along with 2.6GHz, 700MHz will probably be used in Americas, New Zealand and India. 800 MHz and 900 MHz will probably be available and used in Europe.

Finally with LTE being rolled out, it would be easy to upgrade to LTE-Advanced when the standards are finalised in Release-10.

For people interested in this report and topics, the following related presentations are available from GSA:

• Digital Dividend Update - March 2010
• UMTS900 Global Status - March 2010
• Spectrum for LTE Mobile Broadband - Sep. 2009
• From TD-SCDMA to TD-LTE - Sep. 2009
• Low Frequency Options for Mobile Broadband - Sep. 2009
• UMTS 900 case study - June 2009

Renewed focus on TD-LTE

Last year I blogged about the 3G Americas report on TD-LTE and Motorola's gamble on TD-LTE.

The following is from daily wireless blog:

Industry momentum behind Time Division LTE continues to grow with news that a number of major operators and vendors are working with the 3GPP to allow the standard to be deployed in the USA, using the 2.6GHz spectrum band. Clearwire and its partners own the majority of that spectrum. Most of Clear’s 2.6 GHz spectrum goes unused.

Light Reading Mobile notes that China Mobile, Clearwire, Sprint Nextel, Motorola, Huawei, Nokia Siemens Networks, Alcatel-Lucent and Cisco Systems are asking for the 2.6GHz spectrum (2496MHz to 2690MHz) to be defined as a TDD band for LTE.

Outside the United States, part of the band (2570MHz to 2620MHz) is already specified for TDD. The new work will extend this compliance. The report adds that specifications for the US 2.6GHz band for TD-LTE is scheduled to be completed by March 2011.

LTE pioneers TeliaSonera, NTT DoCoMo and Verizon Wireless, will all use different frequency bands for their respective LTE networks, explains TechWorld. So for roaming in the U.S, Japan and Europe to work, modems will have to support 700MHz, 2100MHz and 2600MHz, with more bands to be used in the future. That will be a challenge for roaming, says Light Reading.

The following is from fierce broadband wireless:

The appeal of TD-LTE has widened well beyond China. The recent announcement of Qualcomm to bid for TDD spectrum in India to support a TD-LTE deployment confirms--although it was not required to validate--the emergence of TD-LTE as global technology, likely to command a substantial market share.

Why the sudden interest in TD-LTE?

There are four main factors driving a growth in support for TD-LTE:

• The FDD LTE and TD-LTE versions of the 3GPP standard are very similar. As a result, devices can support both the FDD and TDD interfaces through a single chipset--i.e., without any additional cost. This is a hugely important new development: TD-LTE will benefit from the wide availability of FDD LTE devices that will be able to support TD-LTE as well. Unlike WiMAX, TD-LTE does not need to prove to have a substantial market share to convince vendors to develop devices. Vendors do not need to develop new devices, they simply need to add TD-LTE support to the existing ones.
• There is a lot of TDD spectrum available, and in most cases it is cheaper and under-utilized. 3G licenses frequently have TDD allocations and upcoming 2.5 GHz auction in most cases contemplate TDD bands.
• The increasing availability of base stations that can be cost-effectively upgraded will make it possible and relatively inexpensive for WiMAX operators to transition to TD‑LTE using the same spectrum allocation. The transition will still require substantial efforts and be justified only in some cases, but it will make it easier for WiMAX operators to have roaming deals and to have access to the same devices that LTE operators have.
• Industry commitment to WiMAX 16m, the ITU-Advanced version of WiMAX and successor to the current WiMAX 16e, is still limited.

What's next?

In the near term very little will change. TD-LTE is still being developed and it will take time before it gets deployed beyond core markets like China and possibly a few others like China. In Europe, for instance, mobile operators will deploy LTE in the FDD spectrum and only when they will need additional capacity they are likely to move to TDD. Unlike FDD LTE, TD-LTE will move from initial deployments in developing countries, with a later introduction as a mature technology in developed countries--a quite interesting trend reversal.

WiMAX operators will also be barely affected by TD-LTE in the short term. WiMAX is years ahead in terms of technological maturity, devices and ecosystem. This gives them a strong advantage in comparison to TD-LTE operators: They know the technology already, they have a network, and they have customers. They also have the choice whether to switch to TD-LTE or not--and, more importantly, they have no pressure to do so before TD-LTE has reached the maturity they feel comfortable with or until the WiMAX 16m prospects become clearer.

Huawei's "Two Cloud" solution for Mobile Broadband

In case you are a regular and noticed my recycled image for this post then let me tell you that the post is about recycled ideas ;)

It is a well known fact that I have mentioned at various places in the blog as well that the higher the frequencies, the smaller the cell radius. Since we know that the common deployment frequencies for LTE would be around 2.6GHz then the signal penetration through walls may not be great.

As a result we will be forced to use Hierarchical cells that would allow load balancing and also higher speeds as the smaller cell sizes translate to fewer users and interference.

The following is from Huawei's website:

Based on our roadmap of early success in mobile and fixed broadband network construction, Huawei now responds to the mobile broadband dilemma facing global operators with the unique "Two Clouds" solution.

Employing optimal topologies for access networks providing DSL-level bandwidth for users across the board, the two clouds work together to deliver the most cost-effective means of enhancing user experiences.

• A high speed cloud, consisting of Pico and AP BTSs, is typically deployed in densely-populated urban areas to deliver an average bandwidth of 2 Mb/s.
• A continuous cloud of macro BTSs is applied for wide coverage delivering a bandwidth of 256 to 512 kb/s.

Huawei's "Two Clouds" model allows operators to profitably deploy mobile broadband networks while utilizing an intelligent site management framework to automatically adjust bandwidth and reducing construction, operation, and maintenance costs.

Incorporating this framework, flexible network mapping permits manageable, controllable mobile broadband networks, ensuring continuous network coverage in various scenarios, and provides users with inexpensive, quality broadband services. Very convincingly, Huawei's "Two Clouds" concept can reduce the cost per bit by as much as 70%.

One can guess that Self Organizing Networks would play important part in realising this in practice.

E-UTRAN Mobility Drivers and Limitations

Many years back, when things used to be simple, I wrote a tutorial about Handovers in UMTS. It would be very difficult to write a similarly simple tutorial for LTE. Things are a bit complicated because there are many different conditions in which handovers can take place.

It was also easier to visualise the Intra-frequency and Inter-frequency handovers in UMTS and you can probably do the same to some extent in LTE but with things getting more complicated and carrier aggregation, classifying handovers in these categories may be difficult.

3GPP TS 36.300 has an informative Annex E which details the scenarios in which handovers and cell change can/will take place.

It is best to go and see Annex E in detail. Here is a bit of summary from there:

Intra-frequency mobility: intra-frequency mobility is the most fundamental, indispensable, and frequent scenario. With the frequency reuse being one in E-UTRAN, applying any driver other than the “best radio condition” to intra-frequency mobility control incur increased interference and hence degraded performance.

Inter-frequency mobility: as in UTRAN, an operator may have multiple carriers/bands for E-UTRAN working in parallel. The use of these frequency layers may be diverse. For example, some of these frequency layers may utilise the same eNB sites and antenna locations (i.e., co-located configuration), whereas some may be used to form a hierarchical cell structure (HCS), or even be used for private networks. Some frequency layers may provide MBMS services, while some may not. Moreover, E-UTRAN carriers/bands may be extended in the future to increase capacity.

Inter-RAT mobility: the aspects that need to be considered for inter-RAT are similar to those for inter-frequency. For mobility solutions to be complete with the inter-RAT drivers, relevant updates would be necessary on the legacy (UTRAN/GERAN) specifications. This will add to the limitations, which are evidently more effective in inter-RAT.


The drivers for mobility control are:

Best radio condition: The primary purpose of cell reselection, regardless of intra-frequency, inter-frequency, or inter-RAT, is to ensure that the UE camps on/connects to the best cell in terms of radio condition, e.g., path loss, received reference symbol power, or received reference symbol Es/I0. The UE should support measurements to suffice this aspect.

Camp load balancing: This is to distribute idle state UEs among the available bands/carriers/RATs, such that upon activation, the traffic loading of the bands/carriers/RATs would be balanced. At least the path loss difference between different bands should be compensated to avoid UEs concentrating to a certain frequency layer.

Traffic load balancing: This is to balance the loading of active state UEs, using redirection for example. In E-UTRAN, traffic load balancing is essential because of the shared channel nature. That is, the user throughput decreases as the number of active UEs in the cell increases, and the loading directly impacts on the user perception.

UE capability: As E-UTRAN bands/carriers may be extended in the future, UEs having different band capabilities may coexist within a network. It is also likely that roaming UEs have different band capabilities. Overlaying different RATs adds to this variety.

Hierarchical cell structures: As in UTRAN, hierarchical cell structures (HCS) may be utilised in E-UTRAN to cover for example, indoors and hot spots efficiently. It is possible that E-UTRAN is initially deployed only at hot spots, in which case this driver becomes essential for inter-RAT, not just for inter-frequency. Another use case would be to deploy a large umbrella cell to cover a vast area without having to deploy a number of regular cells, while providing capacity by the regular cells on another frequency.

Network sharing: At the edge of a shared portion of a network, it will be necessary to direct UEs belonging to different PLMNs to different target cells.

Private networks/home cells: Cells that are part of a sub-network should prioritise the camping on that sub-network. UEs that do not belong to private sub-networks should not attempt to camp or access them.

Subscription based mobility control: This mobility driver aims to limit the inter-RAT mobility for certain UEs, e.g., based on subscription or other operator policies.

Service based mobility control: An operator may have different policies in allocating frequencies to certain services. For example, the operator may concentrate VoIP UEs to a certain frequency layer or RAT (e.g., UTRAN or GERAN), if evaluations prove this effective. UEs requiring higher data rates may better be served on a frequency layer or RAT (e.g., E-UTRAN) having a larger bandwidth. The operator may also want to accommodate premium services on a certain frequency layer or RAT, that has better coverage or larger bandwidth.

MBMS: For Release-9, no new mobility procedures compared to Release-8 are included specifically for MBMS. In future releases the following should be considered. As MBMS services may be provided only in certain frequency layers, it may be beneficial/necessary to control inter-frequency/RAT mobility depending on whether the UE receives a particular MBMS service or not. For MBMS scenarios only, UE based service dependent cell reselection might be considered acceptable. This aspect also depends on the UE capability for simultaneous reception of MBMS and unicast.


While the issues mentioned above drive E-UTRAN towards “aggressive” mobility control, the limiting factors also have to be considered:

UE battery saving: The mobility solution should not consume excessive UE battery, e.g., due to measurements, measurement reporting, broadcast signalling reception, or TA update signalling.
Network signalling/processing load: The mobility solution should not cause excessive network signalling/processing load. This includes over-the-air signalling, S1/X2 signalling, and processing load at network nodes. Unnecessary handovers and cell reselections should be avoided, and PCH and broadcast signalling, as well as dedicated signallings, should be limited.

U-plane interruption and data loss: U-plane interruption and data loss caused by the mobility solution should be limited.

OAM complexity: The mobility solution should not demand excessive efforts in operating/maintaining a network. For example, when a new eNB is added or an existing eNB fails, the mobility solution should not incur excessive efforts to set up or modify the parameters.

More details available in Annex E of 3GPP TS 36.300

Home Relays for LTE-Advanced

If you look at the Home eNodeB (Femtocell) architecture, the HeNB is connected to its gateway which in turn is connected to MME/S-GW. There is a considerable amount of technology investment in this approach. The HeNB consists of complete protocol stack, the HeNB-GW is an expensive piece of equipment and there is lots of other things including the management software, etc.

Now in LTE-A, there is a concept of Relays which we have talked about. The Relays do not contain the complete stack (generally just L1 and L2). If capacity is not an issue but coverage, then we may be able to use Home Relays.

The backhaul for Femtocell is Internet whereas for Relay its generally the same Radio resources within the cell. I guess the main thing for Relay is the requirement of reasonably good channel (Line of sight maybe). Home Relays can use the Internet connection but rather than connection terminating in some kind of gateway, it can terminate at the actual eNB.

There are already many advanced antenna techniques that can handle the transmission and reception without much interference and maybe the SON algorithms may need some additional improvements.

The main thing is that if this technology becomes reality then it may cost less than $50 per Home relay and would become really a commonplace.

Femtocells for Beginners

Speech for Mobile to become big industry

Its interesting that its not only Google that experimenting with Voice Recognition and Voice search but a whole lot of other players. Earlier I blogged about Real time Speech Translation and another one was the Voicemail search. Google's search App also allows to search using voice rather than by entering text.

SpeechTek Europe 2010 is a new conference that promises to make everyone aware of the new Speech Technologies and their application in Mobile and other domains.

From EarthTimes:

Produced by the publishers of the industry’s best-read magazine, Speech Technology, SpeechTEK Europe is the sister of the highly successful New York annual event series and aims to capitalise on the wealth of speech innovators based here in Europe.

The conference has been developed by a Steering Committee which comprises some of the industry’s most respected thought leaders. Here they share their insights into the future for speech technologies, how they are developing, and where they will be used.

Loquendo’s Vice President of International Sales, Rosanna Duce, predicts that voice control will be a major growth area in the next five years:

“One important emerging speech technology is undoubtedly the voice control of all kinds of devices, for example, PDAs, mobile phones, DVD players.” She comments, “These technologies are currently being expanded and upgraded to allow all functions to be accessed using voice, thus eliminating the need to use a keyboard. Consumer demand seems to suggest that the option to dictate text messages will be a major source of growth in this area, as will be the reading of incoming messages by a TTS application bundled with the phone/PDA.”

Nava Shaked, CEO of Business Technologies, agrees,

“The combination of voice search engines, internet and mobile is a real opportunity for speech technology growth and influence. This includes the introduction of previously unseen applications for voice user interface and transcription. The combination of voice and video is also promising and will be inevitable in our interaction with multimedia.”

James Larson, the Conference Chair, supports these views,

“Multimodal applications on mobile devices will enable customers to not only speak and listen, but to also read and type and use additional modes in interaction. These apps will be easy to learn, easy to use, and much more natural than current voice-only apps or GUI-only apps. They will always be available, and customers can use them wherever they are, not just at their desktop or in their car.” He concludes, “Multimodal applications on mobile devices will dramatically change how we interact with appliances - TV, radio, environmental control - with the internet, and with other people.”

The SpeechTEK Europe conference programme explores these trends and the implications for the industry as a whole. Real world applications and case studies are a particular feature of the event, so delegates can see for themselves how speech is working in a variety of different environments, how to select and implement the technology, and how to evaluate its performance.

The full SpeechTEK Europe programme is available at: www.speechtek.com/europe2010 along with registration information, details of registration savings, and free entry exhibition tickets.

IPv6 transition in cellular networks gaining momentum

IPv6 is good and we all know that. I has been talked for years but practically it hasnt found much success. Verizon made some noise last year but I am not sure of the conclusion.

Just to recap, IPv4 was introduced back in 1982 and IPv6 work started since 1995. IPV4 uses 32 bit (4 bytes) addresses while IPV6 uses 128 bit (16 bytes) addresses. Theoretically we would now have 2^96 times more addresses than in case of IPv4.

Most of network infrastructure manufacturers have their equipment ready for IPv6 as some of the handset manufacturers. The main driver being that someday soon IPv4 addresses would be exhausted (Internet Assigned Numbers Authority will run out of IPv4 addresses in September of 2011, based on current projections) and their equipment would be ready to provide IPv6 addresses without any problems.

Recently, IETF-3GPP Workshop on IPv6 in cellular networks was held in San Francisco, USA on 1 - 2 March, 2010. There are lots of interesting presentations available here for people who want to dig a bit deeper. The concluding report that summarises the presentations and discussions are available here. Here is a brief summary from one of the reports (with links at the end):

Summary

• Scenarios for IPv6 migration were discussed based on 3GPP Technical Report 23.975
• The discussion focused on validating the scenarios
• General IPv6 transition and deployment guidelines were outlined based on input from IETF
• Solutions for migration and v4-v6 co-existence were presented
  
• Solutions included existing RFCs and working group items but also proposals in Internet Drafts
• Gap analysis wrt transition scenarios was discussed

Conclusions on scenarios

• Scenarios 1 and 3 based on dual-stack and IPv6-only deployments were generally recognized as valid
• See docs IPW100013, IPW100028
• Scenario 2 was also recognized as valid, addressing two separate problems related to insufficient RFC1918 space and subscriber identification
• See doc IPW100027
• Scenario 4 did not receive wide support from the workshop, largely because it was felt that it addressed a problem already solved by other scenarios
• Variants of some of these scenarios were brought up during the discussions, conclusions were not reached on these
• These may need further discussion

Conclusions on solutions

• It was recognized that necessary support in the network and devices is already available to “switch on” IPv6 in 3GPP networks
• Some networks reported running dual stack
• Some networks reported running IPv6-only now
• Solutions enhancing existing mechanisms for dual stack deployments and new solutions for IPv6-only deployments drew wide support
• Gateway-initiated Dual Stack Lite
• Stateful IPv4/IPv6 translation

Next steps: 3GPP

• IETF and 3GPP are expected to focus further work based on the conclusions of the workshop
• Note that the workshop itself does not have the mandate to make formal decisions
• 3GPP is expected to identify possible normative specification impacts, if any, of the preferred solutions
• A need was identified to provide more operational guidelines about IPv6 deployment to 3GPP operators
• The best location for these guidelines is FFS (e.g. 3GPP TR 23.975, GSMA, etc)

Next steps: IETF

• IETF and 3GPP are expected to focus further work based on the conclusions of the workshop
• Note that the workshop itself does not have the mandate to make formal decisions
• IETF is encouraged to continue working on stateless and stateful IPv4/IPv6 translation mechanisms
• These mechanisms are being worked on in IETF BEHAVE group
• IETF is also encouraged to consider new solutions that are not yet working group items
• Gateway Initiated DS Lite
• Per-interface NAT44 bindings addressing IPv4 address shortage
• Note that the workshop has not set any timelines

Mobile Apps market to grow to '$17.5bn by 2012'

A study done for Getjar, the world's second biggest app store, said the market will grow to $17.5bn (£12bn) in the next two years.

The study claimed downloads would climb from 7bn last year to 50bn by 2012 - a 92% year-on-year increase.

It found there had been a gold rush with the number of app stores rising from four before 2008 to 48 today.

The study also suggests Apple's domination of the market could be challenged.

The report titled, 'Sizing up the Global Mobile Apps Market' by Chetan Sharma is available to download here.

Some more interesting stats from the report as follows:

• The overall mobile apps downloads are expected to increase from over 7 billion in 2009 to almost 50 billion by 2012 growing at the rate of 92% CAGR
• The revenue from mobile apps which includes both paid downloads and revenue from advertising and virtual goods is expected to increase from $4.1 billion in 2009 to $17.5 billion by 2012 at the rate of 62% CAGR.
• The overall global subscriptions base is expected to exceed 5 billion by the end of 2010 with over 27% of them being data subscribers
• Non-carrier appstores jumped from a mere 8 to 38 last year
• In 2009, advertising contributed almost 12% to the overall apps revenue.
• The price range of applications in various stores can vary from $0.99 to $999.

Ringtones to help you in your daily life..

I am sure you must have heard of Music being used to torture terrorists or hardened crminals. Now you can have complete different use of music or ringtones in this case. “Well . . . I can definitely feel a bit of adrenalin,” says Yukari Sendo, savouring the mobile phone ringtone like a fine wine, “but it really doesn’t make me want to do any housework.” She flicks through a menu of alternative tunes and settles on one that offers to improve her skin tone through the power of alpha-waves. Ms Sendo and her friend Ayaka Wakabayashi are among an army of young Japanese drawn to the allure of “therapeutic ringtones” — a genre of melodies that promises to ease a range of day-to-day gripes, from chronic insomnia to a rotten hangover. Japan is no stranger to bizarre phone fads but the popularity of the ringtones is perhaps surprising given the flimsiness of the science behind them. Much of the tones’ credibility rests in the solid reputation of Matsumi Suzuki, the head of the Japan Ringing Tone Laboratory, an eight-year-old subsidiary of the Japan Acoustic Laboratory.

Mr Suzuki’s adventures in the realm of mood-altering ringtones follow a career at the National Research Institute of Police Science, where he made award-winning advances in the field of voiceprints. One of his proudest achievements was the development of a synthetic mosquito noise that is inaudible to Japan’s over-60s but supposedly discourages teenagers from “congregating in parks at midnight”.

A spokesman for Index, the giant Japanese mobile phone content provider that sells Mr Suzuki’s ringtones, explains that while there is a shortage of actual experimentation, “the number of downloads suggests the ringtones must be working to a certain extent”. Index’s other innovations include an iPhone application that translates your dog’s bark; the “Bowlingual” automatic canine interpreter draws on an database of woofs from dozens of species.

The first therapeutic tone, a high-energy rhythm, tested for The Times by Ms Sendo and Ms Wakabayashi, was supposed to provide a sudden burst of impetus to sluggardly housewives. Yukari and Ayaka had their doubts.

The tone that is said to improve skin mixes a burst of electro-Schubert with woodland noises such as birdsong and streams. “I suppose it might subconsciously make you think of washing your face, and that is good for the skin,” said Ayaka. “At least, it would certainly send you towards the bathroom.”

Ms Sendo and Ms Wakabayashi were marginally more impressed by the sleep-inducing and sleep-preventing tones, suspiciously akin to a lullaby and a dance track. The one with most practical use, they concluded, was the tone that scares away crows — the sinister jungle ravens that terrorise the dawn streets of Tokyo by pecking at bags of rubbish.

Mr Suzuki’s latest ringtone has been timed to coincide with the Japanese hay fever season. The Ohana Sukkiri Melody emits a series of sounds at different frequencies “so that people can choose the sound that resonates most to their sinus and causes pollen lodged there to fall from the nasal cavity”.

Index admitted that it had not conducted any research on how great a pollen deluge would be induced by the ringtone but said that it was “generally understood” that resonance would help hayfever sufferers if they brought the phone close to their noses.

When it came to testing the hangover chaser ringtone, Yukari and Ayaka were relieved from experimental duties. This popular application works through what Index describes as a careful selection of “pulse-melodies” chosen for their astonishing atunement to the body’s “medical rhythms”. Testers concluded that a fried breakfast, though less portable, still had the edge.

How to avoid network choking in the future?

If you are looking for an answer to this question then you wont find an answer to that here. Probably no one really knows a complete answer to this question right now. A simple answer would be to have a mix of the Macro cells, Micro cells and Femtocells with some way to offload some more traffic via WiFi.

Earlier this month Skype announced that its client would be able to work on most Symbian phones. I have used the Skype client on phones from '3' and they work great. Skype is even available on iPhones and they were downloaded 1 million times in the first couple of days. Now a big chunk of operator profits come from long distance calls and calls when abroad. If we all start using our phones with Skype, its going to bite into the operators profits. That means they will have to recover this profit from us by another way.

Skype on phones will be used in always on mode, meaning that the networks will get loaded and get congested. A simple solution is to have Femtocells at home that can offload the traffic on Internet. These background apps do cause a considerable amount of traffic and recently an Operator blamed the apps for its network woes.

Femtocells have been targeted generally at the residential market with developments going on for Business users as well. Another smaller Picocells and Microcells are also easily and cheaply available nowadays. With the Ad-Hoc deployment of all these smaller cells, Self Organising Networks (SON) may have a big role to play.

What happens where there are multiple networks present in the same place via these smaller cells? Can the back-haul not get congested because of these multiple networks which may be lying Idle most of the time? How would these impact other services that we use on our PC's?

These questions can be easily answered if a single Microcell/Picocell/Femtocell was able to work for Multiple Networks. Practically this may not be possible right now because each network has a different Authentication and Security arrangement.

At least we can start thinking and working on these problems while we still have time. When its too late, we may have to come up with workarounds. These workarounds only cause more headache in the longer term.

Qualcomm's FLO on the go...

Qualcomm's FLO TV is a reality in the U. S. of A. This is the advert which was being shown in the Superbowl

Many popular channels like the CNN are available real time. The following is a review from CNET.

Not everyone is enthusiastic, which is understandable considering the high cost.

I remember reading a research couple of years back which said that users are willing to pay a maximum of £5 for any service like the Internet or Mobile TV over their phone. Personally I think that is right and maybe in the next few months we may see the subscription prices dropping.

I would be interested in hearing from people who have experienced the FLO service first hand.

Motorola (Concept) Phone that will help capture memories

A bit old new but new for me.

The idea, known as the Motorola 2033 Concept Series, was based around what mobile phones might look like in the year 2033.

The 2033 concept would allow for the device to capture memories directly from the user’s brain, through a process Motorola calls "organic memory capture". And if that wasn't enough, the 2033 concept would also allow users' to completely augment their eyesight through a process called Second Sight.

HSPA+ to reach 168Mbps in Release-10

Just when we thought that we have squeezed every bit out of HSPA, a surprise waiting is the speeds of upto 168Mbps in the downlink. Going back to the 3G Americas report, there is a section in the end that details HSPA+ enhancements for Rel-10:

Rel-8 introduced dual-carrier HSDPA operation in the downlink while Rel-9 similarly introduced dual-carrier HSUPA operation in the uplink and also enhanced the dual-carrier HSDPA operation by combining it with MIMO.

Further enhanced multi-carrier HSDPA operation is being specified for Rel-10, where the base station will be able to schedule HSDPA transmissions over three or four carriers simultaneously to a single user with the carriers are spread over one or two frequency bands. Solutions specified in earlier releases can be reused to a large extent. The difference is that now it is possible to configure a UE with one primary serving cell and up to three secondary serving cells. As in earlier releases, the secondary serving cells can be activated and deactivated dynamically by the base station using so-called “HS-SCCH orders.” With MIMO transmission on all four carriers, the peak rate would be doubled to 168 Mbps compared to Rel-9 and for typical bursty traffic the average user throughput would also experience a substantial increase.

Remember, I posted a blog on data rates calculation? The maximum data rate in Release-8 HSDPA is 42Mbps. With Dual-carrier operation, this could be doubled to 84Mbps. As you can probably guess, with 4 carriers, this will become 168Mbps ;)

For people who are less technically inclined, can check this Ericsson presentation on HSPA+ data rates. For people who may become sleepless without some technical references can check this report from RAN WG#1 meeting#59. If you are not sure what RAN WG#1 is, check quick tutorial on 3GPP here.

Going back to the 3GPP report, section 5.4 lists the details of 4 carriers HSDPA. It would be interesting to see what happens in cases where initially there were 4 carriers but then in a particular spot it changed to 2 carriers, and vice-versa. People who have yet to work on LTE may not have to worry too much as HSPA is being future proofed against the threats of LTE and WiMAX.

Interestingly enough, HSPA+ offers a better and cleaner solution at the moment especially with regards to voice calls and handing over to GSM then LTE or WiMAX.

It wont come as a surprise if the HSPA+ camp are able to pull out some new tricks from their bag just in time for Release-11.

3GPP and Broadband Forum Collaboration on Fixed Mobile Convergence Standards

Fixed/Mobile Convergence (FMC) was the key topic that brought 3GPP and the Broadband Forum together for their first joint workshop, held February 18-19 in San Francisco. The two-day workshop was attended by 120 industry experts, who reviewed over 40 contributions focused primarily on use cases and joint requirements.

The attendees, primarily 3GPP and Broadband Forum members, also included representatives from ETSI TISPAN, ATIS and other standards bodies. The diverse group came together with a shared goal; to start the process of aligning new FMC work in each organization to best address both fixed and wireless management requirements. The two days spent together allowed the group to identify the key issues at hand and the work that needs to be done. With words of appreciation and encouragement from workshop co-chairs, Stephen Hayes of 3GPP and Dave Allan of the Broadband Forum, each organization took away work items that address both near term and long term next steps for both 3GPP and the Broadband Forum.


Through liaison communications and technical contributions into each organization, joint requirements will be shared, and another workshop is envisioned for the future after a scope and gap analysis is performed by the organizations.

Evolution of 3G Networks: The Concept, Architecture and Realisation of Mobile Networks beyond UMTS

This book has a title that can be a bit misleading but the main focus is on LTE network. One of the main problems that I generally notice is the lack of understanding of the bigger picture from the network point of view. This book can help fill that gap. The book starts with Mobile Network Evolution in General and moves to explain the evolved 3GPP network.

The different layers and interfaces have been explained quite well and the concepts have been well illustrated with the diagrams. A lot of books have diagrams that are verbatim copy of the standards of illustrated in a complicated way, these have been avoided in this book. To illustrate my point lets look at this image below that shows example arrangement of bearers with multiple PDN connectivity.

Later on the signalling for different scenarios have been explained in a rather nice way. For example of we look at PDN connectivity again, its rather simply explained.

There are many examples of signalling and once they are complete, there is a chapter looking at different protocols like GTP, PMIP, DIAMATER, SCTP, etc.

The book is a bit pricey though but worth the investment if your focus is on the signalling side of things and if you are required to understand the concepts quite well. You can also have a look at the book n google books as embedded below:

Bluetooth 4.0 promises to be more successful than Bluetooth 3.0

Apparently the Bluetooth 3.0 has a problem that it consumes too much power so even though the specs have been available for quite some time, they haven't been rolled out.

The Bluetooth Special Interest Group has said that the new version, Bluetooth 4.0, could be launching in the 4th quarter of this year with devices such as headsets, phones and PC’s all getting the technology.

The latest specification allows devices with smaller batteries to utilise Bluetooth. Previous versions of BT required that a device had at lease a AAA or larger capacity battery to function. The new 4.0 specifications allow for smaller devices that require coin-cell batteries to run.

As well as utilising less power, the device also has higher speed data transfer. Version 3.0 was launched last year although it kind of fell flat on it’s face due to the power requirements needed. Version 4.0 fixes those problems.

The new specification will carry the high-speed Wi-Fi feature introduced with Bluetooth 3.0. That allows devices to jump onto Wi-Fi 802.11 networks, where it can transfer data at up to 25Mbits per second.

Hopefully with the lower power requirements and the options to switch to 802.11 networks we should start seeing more devices using the Bluetooth specification.

However, Forrester Research analyst Charles Golvin believes the new standard nonetheless holds considerable appeal.

"These protocols are designed to be very efficient because they are delivering small bits of data," Golvin told PC World, adding that current technologies expended far too much energy to transmit data over short distances. “They'd be like pulling out a cannon to kill a mouse,” Golvin said.

Despite being certified nearly a year ago, the first Bluetooth 3.0+HS devices have yet to appear on the market.
