TENAA, China’s equivalent to the FCC, has released documents clearing a pair of iPhones packing TD-LTE radios, says Engadget. Currently the carrier has approximately 756 million subscribers, around 63% of the 1.2 billion wireless subscribers in China.
This hints that Apple’s iPhone 5s and 5c will shortly be available to China Mobile, the world’s largest mobile carrier. China Mobile uses TD-LTE in the 2.6 GHz band, similar to Sprint and Softbank. They also use 2.3 GHz TD-LTE for indoor coverage.
According to Qualcomm, LTE TDD has been commercial since 2011 and is gaining global momentum.
The initial global unpaired bands include 2.3GHz (Band 40) used in India and China, the 50MHz slice of 2.6 GHz (Band 38) used Europe, and up to 190 MHz in Band 41 in the U.S., Japan and China. China Mobile has conducted TD-LTE roaming testing with partners such as India’s Bharti, Japan’s SoftBank/Sprint, and South Korea’s KT.
LTE Advanced, which supports Time Division LTE, also supports upcoming technologies like LTE Direct, a new proximity based device-to-device technology, and LTE Broadcast, for efficient multi-casting of video and data.
