Qualcomm: How we're making future 4G LTE devices work anywhere

Complete 4G roaming is very much on the cards, says says Qualcomm's Roberto di Pietro. Qualcomm has just announced the RF360 - a single chip that provides access to over 40 mobile bands globally.

4G LTE is provided on many frequency bands in different countries and it's this variation that's made the RF360 necessary.

"LTE is the first technology that's embracing all the regions at the same time but on the other hand, LTE is a challenge to handle all the different spectrum from region to region and even from country to country," di Pietro explained to us in a chat at MWC 2013 this week.

"We really want to have a single device to [handle] all this spectrum. RF360 is the first step towards the global roaming dream. You can have a single device. This was one of the bottlenecks preventing the [widespread] adoption of LTE. Our customers can utilise a single platform, rather than developing 3, 4 or 5 [globally]."

It's good news for handsets manufacturers who have to develop different handsets for different markets. Even the iPhone 5 has three different versions globally - two different GSM models that work on different LTE bands and then one CDMA model.

di Pietro says it won't take long for the technology to be adopted, and believes it's "another step toward the democratisation of LTE", as the technology moves towards mass adoption. "This year we'll have devices from the high tier to the low tier with multi-mode LTE, HSPA+, 3G and GSM in a single chip. You can imagine how tough this has been for our engineering team to put this on a single piece of silicon. We've got got more or less 40 bands on this chip. It's kind of a multi-dimensional complexity."

Enabling better battery life

We also quizzed di Pietro about the advances made in terms of battery life - and consumer demand for bigger screens yet with longer standby times. "Everything is built with the assumption we need to optimise power consumption - and not just the architecture as a whole, but every single core. We are delivering. Even in terms of performance the Snapdragon 600 and 800 are moving from 30-40 per cent battery performance improvements to 70 percent with the 800."
