TTCL and Zantel to adopt CDMA technology

9 Jan 2006

Tanzania Telecommunications Company Ltd (TTCL) and Zanzibar Telecommunications (Zantel) have announced plans to begin rolling out code division multiple access (CDMA) technology, in preference to the global system for mobile communications (GSM), widely used elsewhere on the continent. The move is intended to capitalise on the platform’s inherent perceived strengths over GSM. CDMA, widely used in Latin America and Japan, transmits simultaneous signals over a shared portion of the spectrum. It needs fewer cell sites than the rival system, has an improved calling capacity, can provide coverage of inhospitable terrain, and can be less costly to deploy. According to TTCL’s communications manager Issa Semtawa, the company hopes to start using CDMA technology from April. Pilot projects have been successfully deployed in Dar es Salaam, Arusha, Mwanza and Zanzibar. Chinese firm, Huawei, is the main contractor for the project. Meanwhile, George Chimalilo, the marketing manager for Zantel, said CDMA would be used in the fixed line, data and internet services.
