Simultaneous Voice and LTE (SVLTE)

When LTE is an overlay to a CDMA/EV-DO network, the current de facto standard for voice delivery is Simultaneous Voice and LTE (SVLTE). In this arrangement, voice service is deployed as a 1x service running in parallel with LTE data services. For this solution to work, the handset needs to have two radios that are on simultaneously. The problem that is obvious is that the power consumption would generally be higher as two radios are on when the voice call is ongoing. The advantage (and I think its a big advantage) is that the data speeds are not affected by ongoing voice call and at the same time the state machine is simple.

For some reason this idea is not very popular for the 2G/3G evolution to LTE as the reliance will be on the CS Fallback. I had discussed this idea in the LTE World Summit and had blogged about it, you can read more details and comments here.

There is also a recent whitepaper from Huawei that covers these issues going towards VoLTE. Its available here.

Edit 06/10/11: Changed the acronym of SVLTE from 'Simultaneous Voice Over LTE' to 'Simultaneous Voice and LTE' as this is correct and referred to elsewhere.

LTE Survey from Telecom Asia and Maravedis

Click on the pic. to enlarge

Interesting survey results. As seen in Fig. 2 above if Video and P2P is the main drivers for LTE for some operators, soon they may end up in trouble as the users will consume as much as allowed and given opportunity. An interesting thing though is that the operators are thinking of a fallback strategy that includes Wifi, Femtocells and Picocells (Fig. 3). Finally (Fig. 4), interesting to see that operators believe in launching Smartphones for LTE, I guess CS Fallback is the only possible option for the time being (and maybe for some time to come).

Future Mobile devices: Winners & Losers in technology

NTT DOCOMO announced a range of futuristic ideas and products that they are going to demo at CEATEC this month. Some of the products/ideas as follows:

Extra-high-speed, next-generation LTE service

• Experience the first Xi-compatible tablets “docomo Tablet GALAXY Tab 10.1 LTE SC-01D” and “docomo Tablet ARROWS Tab LTE F-01D,” set for October release.
• Try out new broadband services for the high-performance Xi network, including internationally popular services and games such as Hulu and Qik Video.

Smartphone-ready device to measure acetone in breath for diet support

• The compact device measuring acetone for diet support that can easily be used anywhere and anytime.
• Visitors blow into the smartphone-connected device to measure acetone in their breath-the higher the concentration, the greater the level of hunger.
• The device also identifies when people are burning fat, based on the concentration of acetone in their breath, which rises when body fat is being burnt.

Smartphone jacket for ultra-high-speed battery charging

• This special battery jacket for smartphones achieves a full charge in just 10 minutes. A recharging indicator will show how the jacket will charge a smartphone 10~15 times faster than conventional charging devices.

Smartphone jackets for various purposes

• Three types of special jackets for smartphones that are equipped with sensors that can be customized to measure ultraviolet light and bad breath, gamma radiation and body fat.

Environmental sensor network

• Presentation of real-time atmospheric data (temperature, humidity, wind direction/speed, precipitation, ultraviolet intensity) collected by DOCOMO’s nationwide network of approximately 2,500 environmental sensors, and a demonstration of visualizing the data using augmented reality.

The DOCOMO booth will also offer a mobile handset recycling service, where visitors can drop off old and unwanted mobile phones, rechargers, battery packs and stands. This service is open to all mobile phone users regardless of their carrier, and mobile phones will be destroyed using specialized tools to ensure the protection of personal information.

You can watch these in action here:

I also recently attended a Cambridge Wireless Handset SIG event and David Wood gave an interesting presentation that is embedded below:
