Of particular interest to NSN in the coming quarters will be TD-LTE, a variant of 4G technology that is being used in many emerging markets such as China and India.
China Mobile, for example, is the largest carrier in the world with over 700 million subscribers and plans to build out a TD-LTE network on 2.5 GHz spectrum.
Interestingly, our brethren over at Engadget Chinese also spotted a TD-LTE-ready Samsung Galaxy S III at China Mobile's MWC booth (note the "China Mobile 4G" logo on the back of the phone, pictured above), but it wasn't mentioned at the Global TD-LTE Initiative summit at MWC.
