A new survey by GSA - the Global mobile Suppliers Association, confirms that a number of CDMA operators are facing falling market share and responding by switching to the GSM family (GSM/EDGE, WCDMA-HSPA) for business growth. Some operators choose a dual system strategy, but most prefer to migrate their whole customer base to GSM, which is the global standard for mobile communications. The GSA survey ‘CDMA to GSM/WCDMA Migration - June 30, 2006’ confirms 25 operators who are deploying or operating GSM/WCDMA technology either as an overlay, or as a replacement of the existing CDMA systems. No instances have been identified of a network operator abandoning GSM in favour of CDMA. The vast majority of TDMA operators also chose a migration path to the GSM family.
