Tsinghua Lecturer: TD-SCDMA Has Failed

Netease Tech, 12/20/07

At the first Mobile Internet Conference held recently in Beijing, Tsinghua lecturer Zhu Lingyun stated that the TD-SCDMA standard has essentially failed. The primary reasons he gave for this were:

Excessive levels of bureaucracy at Datang have led to low levels of R&D efficiency for the TD-SCDMA standard, with a series of unresolved problems not being exposed until testing was performed in 2007;

Patent discussions have failed to make any progress over a 3 year time period, with TD-SCDMA still facing large patent licensing fees;

Policy management is a mess, with TD-SCDMA policy decisions being pulled in different directions by the Ministry of Information Industry (MII), the State-owned Assets Supervision and Administration Committee (SASAC) and the National Development and Reform Commission (NDRC), which has had a negative impact on implementation efforts;

Telecom operators have neglected TD-SCDMA and focused on the more stable WCDMA, which foreign operators have been using for years.
