Brian: That is a surprisingly evenhanded 3G analysis, considering the source is China Telecom. They seem to be seriously thinking of a CDMA one/GSM overlay, as demonstrated in the Vodaphone trials. 2. GSM-CDMA GSM-CDMA was proposed by Qualcomm, the poineer of N-band CDMA. Based on cdmaOne, it allows GSM-MAP to airinterface with CDMA, integrating GSM and cdmaOne and moving forward to IMT-2000. Those GSM operators planning to adopt GSM-CDMA can pile CDMA base stations on their existing GSM network. Those CDMA base stations can work at GSM frequency band or any other frequency band such as 800MHz, 1800MHz, 1900MHz, PCS/PCN or even 3-G UMTS frequency band. These CDMA base stations can be managed by one or multiple BSC and directly connected to existing GSM MSC through GSM A interface. Dual-mode handset will search GSM-CDMA. In case of GSM-CDMA network found, it works at GSM-CDMA air interface. As a full-function GSM terminal, the handset supports global roaming and has all those common features. Its SIM card can work both in GSM terminal or GSM-CDMA terminal. Up to date, GSM-CDMA has passed preliminary tests. Vodafone and Qualcomm have jointly set up a trial network. A new model commercial CDMA handset with GSM software and SIM card has been rolled out. Demonstration of Voice and GSM service has been given. Other experiments including one in Asia are expected to take place in the second half of 1999 before GSM-CDMA terminals and infrastructures are put into commercial use. The standardization work of GSM-CDMA is also in progress to achieve international recognition for infrastructures purchase by operators and to broaden availability of handest and infrastructure suppliers. The make or break of GSM-CDMA mainly relies on cost and price of dual-mode handset, the possibility to achieve investment advantages during the network migration process and market deployment speed. In a word, GEDGE and GSM-CDMA may become important technological path in the transition from 2-GTDMA to IMT-2000.
