Greatwall nets CDMA system

Motorola says its Cellular Infrastructure Group has completed installation of a new code division multiple access (CDMA) system for Beijing Telecommunications Greatwall Mobile Communications Co, the mainland's first CDMA operator. CDMA is a second-generation digital cellular technology that uses radio spectrum. The initial installation of the Beijing Greatwall CDMA network, which began in March and consists of more than 30 base stations, has been put into service with subscribers on a trial basis.

Motorola CIG is the only system supplier for this CDMA network, which has initial capacity for 43,000 subscribers and is the first and largest CDMA system installed in the mainland.
