LG Electronics showcased its first TD-LTE device at Mobile World Congress, an event which also saw Nokia and Samsung iterating their support for the technology.

The company said its demonstration used a “modified Optimus G, LG’s flagship smartphone”. It said that it will rollout commercial devices in China “in the second half of the year, when China Mobile launches its TD-LTE service”.

“TD-LTE has the potential to cover 2.7 billion people in Asia alone and today’s demonstration proves that this technology is ready for consumers. LG is committed to offering a range of TD-LTE smartphones based on our unrivaled leadership in 4G LTE technologies,” said Jong-seok Park, president and CEO of LG Electronics Mobile Communications.

At Congress, Samsung said that it will offer a commercial device with both TD-LTE and FDD LTE later this year. Nokia also said it is readying devices supporting the technology.

While TD-LTE is being heavily supported by China Mobile, according to the Global TD-LTE Initiative operators have already launched services in markets including India, Poland, Saudi Arabia, Japan and Russia, with 20 more having firm deployment plans in place.
