Qualcomm and Ericsson demo VoLTE to 3G switch without dropping call

Posted by newbie Thursday, February 2, 2012 0 comments
Qualcomm and Ericsson have completed the first VoLTE handover of a voice call from an LTE network to a WCDMA one, paving the way for high-speed smartphones that can handle voice as well as data.
The proof-of-concept took place in late December, using a Snapdragon S4 MSM8960 3G/LTE based device on an Ericsson network, seamlessly transitioning the in-progress call to 3G when LTE coverage was no longer available.
�As LTE networks are deployed alongside 3G networks,� Cristiano Amon, senior vice president of product management at Qualcomm said in a statement, �the ability for multimode 3G/LTE mobile devices to connect to different network technologies will be an important part of providing the best possible mobile voice and data experience to consumers.�
The demo used Single Radio Voice Call Continuity (SRVCC), allowing a single radio to shift a call between 3G and 4G networks. Existing LTE devices have used CSFB (circuit-switched fallback technology) which automatically step a radio down from 4G to 3G when a voice call is to be made. Paired together, manufacturers can use a single 3G/4G chip rather than two separate radios.
Verizon is tipped to be trialling VoLTE in two US cities currently, with a full rollout believed to be intended for 2013. The carrier demonstrated the technology in early 2011, though not with transition to a 3G network, and has since committed to including LTE support in all its future smartphones.

White HTC Sensation running ICS to land March 1

Posted by newbie 0 comments
We have some good news for owners of the HTC Sensation smartphone. A press release has been published that says the HTC Sensation will get the official Android 4.0 Ice Cream Sandwich update soon. HTC doesn�t give a specific date that the update will come, simply saying it will come out OTA soon. HTC also dropped information on a new version of the Sensation that is coming to the Netherlands.

The new version of the HTC Sensation will be identical hardware wise to the existing version and the difference will be that the new phone comes in an ice white color. That ice white color looks more like silver to me. The HTC press release says that the phone will land on March 1 in the Netherlands and will already be running Android 4.0 when it hits. There is no word on an official launch date in other countries.
The software update will bring some nice new features such as faster browsing and the ability to unlock the device using face recognition. The update also offers more integration with Google+ and will bring a host of other new features and fixes. Be sure and let us know when you are able to get the Android 4.0 update on your Sensation.

Facebook Phone could break through site�s social mobile limbo

Posted by newbie 0 comments
Facebook�s mobile strategy faces renewed attention IPO excitement cools, with the company citing cellphone users as a huge source of potential growth though warning it is currently at the mercy of Apple and Android. According to Facebook�s SEC filing, 425m active users accessed the social network while mobile in December 2011 alone, more than half of the total number of active users in fact. The figures are likely to renew speculation that Facebook will try to make its own play for the smartphone market.
Currently, Facebook points out, there are no mobile adverts in play, despite the huge potential audience for advertising. It�s an issue the company suggests might in fact negatively impact Facebook�s bottom line: even if mobile users grow, they�re not contributing to Facebook�s purse.

�Although the substantial majority of our mobile users also access and engage with Facebook on personal computers where we display advertising, our users could decide to increasingly access our products primarily through mobile devices � We currently do not show ads or directly generate any meaningful revenue from users accessing Facebook through our mobile products, but we believe that we may have potential future monetization opportunities such as the inclusion of sponsored stories in users� mobile News Feeds� Facebook IPO
That�s the most obvious cloud on the horizon; the other, the IPO documentation suggests, is a lack of control over the most popular mobile platforms in play today. Facebook runs the risk of being marginalized should Apple or Google decide to prioritize other services, including their own in iOS and Android. It�s something Facebook has already seen, in fact; Apple opted for Twitter for its in-depth social integration in iOS 5.0, while Google has been pushing its own Google+ network heavily in recent months.
�We are dependent on the interoperability of Facebook with popular mobile operating systems that we do not control, such as Android and iOS, and any changes in such systems that degrade our products� functionality or give preferential treatment to competitive products could adversely affect Facebook usage on mobile devices�
The obvious path, then, is a smartphone of Facebook�s own. HTC and others have already experimented with baked-in Facebook integration, though the handsets themselves have failed to set the market alight. However, the social network is believed to have long harbored ambitions for an in-house Facebook phone, built on a modified Android base, with the first-gen project even hoping to design its own hardware.
The sheer costs involved supposedly scuppered those plans, and Facebook apparently turned to HTC once more with the promise of an HTML5 based OS the site would build on top of hardware from the smartphone manufacturer. However, with the promise of a huge IPO payout on the horizon, Facebook could well decide to head back into the labs and renew its efforts on an official Facebook handset.

Corning and Samsung Mobile Display team for OLED glass partnership

Posted by newbie 0 comments
Corning and Samsung Mobile Display have announced they�ve teamed up to form a new OLED glass partnership. The two firms are establishing a new joint venture to many factors special the glass substrates that will be used in the OLED display manufacturing market. The joint venture will use Corning�s new Lotus Glass and Samsung�s OLED display tech.

Lotus Glass is an interesting product from Corning that is a glass substrate that goes over the top of an OLED display and can be flexed without breaking. That allows it using curved handsets and should make it last longer in the real world by being able to deform when dropped or hit rather than breaking. The joint venture will supply the OLED backplane glass substrates for Samsung Mobile Display along with the broader Korean market.
The OLED market is expected to grow rapidly with many smart phones moving to the screens for the superior color reproduction and image quality. At the same time, the screens tend to use less power than traditional LCDs making for longer battery life. Larger OLED screens are also being used in TVs, and we saw several sets of this sort during CES. It�s not clear exactly when Samsung Mobile Display and Corning screens will begin to hit the market.
