LG today demoed a Optimus G that supports China Mobile’s TD-LTE network and revealed that it will provide a full line of TD-LTE devices for the world’s largest mobile operator.

LG said it will roll out TD-LTE smartphones in China in the second half of the year when China Mobile launches its TD-LTE service. The LG Optimus G is currently available on Sprint and AT&T. It was the world’s first smartphone to feature a quad-core processor and 4G LTE connectivity.

Four TD-LTE phones from HTC and LG, as well as Chinese handset makers Huawei and ZTE were unveiled on Tuesday. They can use both Time Division and Frequency Division LTE networks, as well as China Mobile’s 3G and GSM networks. The high-end handsets featured 4.7-inch HD screens and multi-core processors.

China Mobile plans to launch 4G wireless services in more than 100 cities by the end of the year, the chairman of world’s largest wireless operator said today at MWC, and expects to have 200,000 base stations supporting TD-LTE by the end of 2013.

China Mobile and Clearwire share TD-LTE technology and spectrum. Clearwire’s TD-LTE service is expected to begin in mid-2013 and is expected to provide roaming service with China Mobile and Softbank in Japan.

Engadget speculates that along with the Optimus G (specs), the two companies may be evaluating new smartphones such as the 4.7-inch Optimus F7 and the 4.3-inch Optimus F5, along with the 4.3-inch L7II and the smaller 4-inch L5II, all announced this week at MWC, as candidates to make the TD-LTE leap.

The LG Optimus G Pro is the 5.5-inch Android phone/tablet unveiled this week at Mobile World Congress. It takes all of the hardware and software of the original, Optimus G, introduced in the fall of 2012, and expands it to a larger platform. The G Pro display sports a 1920×1080 resolution, for about 400 pixels per inch and is powered by a 1.7 GHz quad-core Qualcomm Snapdragon 600 processor.

“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,” said Dr. Jong-seok Park, President and CEO of the LG Electronics Mobile Communications Company. “LG is committed to offering a range of TD-LTE smartphones based on our unrivaled leadership in 4G LTE technologies.”

The world’s first dual mode HD voice over LTE (VoLTE) call between TD-LTE and LTE FDD was demoed this week at MWC. The demonstration was accomplished on Ericsson’s commercially verified LTE TDD/FDD converged radio solution and mature IMS platform, using Renesas Mobile’ quad-mode chipsets. It permits international roaming independent of consumers’ device capabilities.

Airspan Networks says that it has started the deployment of a 2.6 GHz TD-LTE network with Brazilian Telco ON in Sao Paulo using its Air4G small cell.

NSN’s LTE Advanced network for Docomo will use remote radio heads, with baseband processing virtualized in the cloud, delivering 300Mbps capacity.

Alcatel-Lucent’s TDD Metro Radio houses two of ALU’s lightRadio ‘cubes’ integrated with a directional antenna. China Mobile is deploying the 2.6 GHz TD-LTE Metro Radio in Shanghai, Nanjing and Qingdao with a variety of TD-LTE handsets providing access.

Come on, Google, buy some 2.6 GHz already. I’m ready for $19.95/month service!
