ARLINGTON HEIGHTS, Ill.-Motorola Inc.’s Cellular Infrastructure Group announced it completed tests for Code Division Multiple Access intersystem network roaming in Beijing.
The tests were conducted jointly with China Telecom Greatwall Network, which is a cooperative entity between China’s Ministry of Posts and Telecommunications and China Electronic System Engineering Co.
Three other CDMA trials are currently taking place in the Chinese cities Guangzhou, Shanghai and Xian. The inter-system networking uses the Interim Standard-41 Revision B, allowing subscribers on one vendor’s infrastructure system to roam to another’s.
