Mobile operator China Mobile and telecommunications equipment supplier ZTE showed this week a smartphone operating on a 4G (fourth generation) LTE TDD network.
China has been holding large-scale trials using LTE TDD technology in a bid to move the country to faster 4G networks. The trials are expected to last until the end of 2012.
The smartphone, which was demonstrated during the Universiade sporting event in the Chinese city of Shenzhen, is a multi-mode phone that operates on the LTE TDD (Long-Term Evolution Time-Division Duplex) standard, as well as China Mobile's 3G TD-SCDMA (Time Division Synchronous Code Division Multiple Access) network standard, according to a statement from ZTE.
It also features a 3.5 inch touch screen and uses the Android 2.3 operating system.
LTE TDD, also known as TD-LTE, is one of two LTE variants that China Mobile is trying to promote as a global standard. As part of this effort, China Mobile has been pushing for the development of lower-cost smartphones that can operate on LTE TDD networks.
The other LTE variant, LTE FDD (frequency division duplex), is largely being used by telecommunications companies in North America and Europe.
China Mobile has more than 600 million mobile phone users, making its customer base a major market for handset manufacturers including ZTE. Taiwanese chipset vendor MediaTek said earlier this week it has developed a handset for use on LTE TDD networks. The device is still being tested, and the company plans to trial the device in China soon.
