Upset with Siemens TD-SCDMA 3G standard

date: May 28, 2001

Siemens is hitting technical difficulties in China with its home grown TD-SCDMA 3G network standard after it missed a date for its first field trial in April and the second near the end of May due to governmental reasons.

In Beijing, some 200 Siemens engineers and local partner Datang Telecom are building 3G standard called TD-SCDMA for the Chinese market.

Siemens was scheduled to carry out the first field trial in April this year. Jurgen Lagleder, head of technology division of Siemens in China said Ministry of Information Industry had failed to grant approval for the trial to all western companies - not only to Siemens but also to its foreign competitors.

The Chinese government did not give out reasons.

TD-SCDMA is an unproven 3G standards unlike WCDMA or cdma2000 and is known as a lesser and undeveloped technology. Siemens make a first phone call using TD-SCDMA under lab conditions in March 2001, unlike the other two standards that have been under development for years, T-SCDMA is relatively a new technology.

China was set to use TD-SCDMA, but the US department of communication put massive pressure on Beijing to shift the standard to cdma2000 to please US companies, and is now be under review and a decision on its final 3G standard be make at the start of 2002.
