China Mobile (CHL) will initiate a large scale HSDPA (High Speed Downlink Packet Access) test in the next two months as a final preparation for the upcoming 3G roll-out.

Many manufacturers, including Shanghai Bell Alcatel, will participate in the test.

HSDPA supports higher speed data services and can be upgraded directly from WCDMA.

China Mobile's current 384kbps WCDMA platform is not so stable, and therefore the telecom is moving to HSDPA.

In related matters, Beijing-based T3G Technology, backed by Philips, Datang Mobile and Samsung Electronics, have said its TD-SCDMA chip set had demonstrated HSDPA capability in a high-speed data transmission during interoperability tests with TD-SCDMA infrastructure vendors Datang and ZTE.
