Express Logic has entered into a software license agreement with Datang Mobile for Datang to use Express Logic's ThreadX RTOS in its products for the TD-SCDMA sector.

TD-SCDMA, proposed by Datang Telecom Technology and Industry Group on behalf of the Chinese government, was approved by the International Telecommunication Union (ITU) in May 2000 and by the 3rd Generation Partnership Project (3GPP) in March 2001 as one of the 3G mobile communications standards.

TD-SCDMA is the Chinese contribution to the ITU's IMT-2000 specification for third-generation (3G) wireless mobile services.

Datang and Express Logic also are entering into extensive discussions intended to enable Datang Mobile to distribute Express Logic's ThreadX RTOS throughout the world.

Under this new agreement, Express Logic's products will be integrated into Datang Mobile's UE (User Equipment) solution for 3G wireless phone equipment where ThreadX would be used to manage the software that controls RF communications between the phone and network base stations.
