TD-LTE goes mainstream with a new performance promise

China Mobile's budding network is helping to pique interest in a different way of using scarce spectrum

By , IDG News Service |  Mobile & Wireless

China Mobile Hong Kong has already launched a combined TD and FDD network. It puts subscribers on TD-LTE where it's available, then shifts them onto FDD where possible, and puts them onto GSM when necessary. All these transitions are transparent to users, Lei said.

The pre-commercial network in mainland China is growing rapidly despite the fact that China Mobile can't offer commercial service yet. There are about 20,000 base stations there today and will be 200,000 in 100 cities by the end of this year, Lei said. And China Mobile is not expected to be the only Chinese carrier to deploy TD-LTE.

That bodes well for a high-volume market that should make TD-LTE devices cheap and plentiful in other parts of the world, with the help of big silicon vendors, analysts said. "It really depends on guys like Qualcomm to make it happen," Marshall said.
