Spreadtrum Recently Realized TD-SCDMA/GSM Dual-Mode Auto Roaming
Function for Commercial Use Based on its SC8800 Dual Mode Chip Platform
BARCELONA, Spain, Feb. 12 /Xinhua-PRNewswire/ -- Dual-Mode Auto Roaming refers to a dual mode handset function in a 3G network, where the handset selects 3G network in a dual 3G and 2.5G network environment, and switch to GSM network when it goes to a non-3G covered area. As only a few cities are covered in the initial phase of TD-SCDMA network construction, users with such a dual-mode auto roaming phone can get in and out of TD network freely, without manually changing handset settings, so users can experience a real seamless service.
Realizing the 3G industry trend in China, Spreadtrum announced in the 3GSM World Congress that, it has spent its endeavor onto TD-SCDMA/GSM dual mode development since the first day it was involved in the TD industry. Up till now, Spreadtrum's TD-SCDMA solution is the sole dual mode solution in the TD-SCDMA industry. This function has been unanimously recognized as TD-SCDMA handset basic function in this industry. Spreadtrum's dual-band auto roaming function has not only improved the dual mode function but also been a step forward to the TD-SCDMA commercialization.
Handset manufacturers such as Newpost has successfully designed TD-SCDMA phones with the dual-band auto roaming function based on Spreadtrum platform for commercial purposes. Now, these handsets have been sent to TD-SCDMA test network carriers in Tsindao, Xiamen and Baoding and been distributed to test users.
