China Mobile (NYSE: CHL; 0941.HK) has revealed that the company is currently cooperating with chip and terminal manufacturers to research and develop new interoperable 2G and 3G technology, and is now conducting tests of the technology.
No problems currently arise when TD-SCDMA mobile phones transfer to the GSM network, however when GSM mobile phones transfer to the TD-SCDMA network, phones must be restarted before they can operate correctly. China Mobile has stated that, once developed, the new technology will allow for smooth transitioning between the GSM and TD-SCDMA networks. Once the new technology is launched, current interoperable software will also need to be upgraded.
