Hyderabad: Tata Teleservices Limited, the private basic operator of Andhra Pradesh, has added 12 more CDMA (Code Division Multiple Access) cell sites in the twin cities to its existing base of 18 cell sites. These cell sites will increase the overall coverage area to 150 sq. kms in Hyderabad, from the current level of 110 sq. kms aimed at improving the quality of voice transmission on the wireless circuit. The network is also designed to help improve the quality of voice transmission to be experienced on Tata Mobitel and fixed wireless connections.

Speaking on the expansion, Mr Ajay Pandey, COO Tata Teleservices Limited said "In keeping with our plans to expand the coverage area for our wireless customers, we have added 12 more CDMA cells sites as the first phase of our expansion."

Among the various technologies available for wireless deployment, a CDMA network needs lesser number of cell sites to cover the same area vis-à-vis a GSM network. This has been done to cater to the needs of its customer base. The increase in cell sites is part of the first phase of the Rs 500 crore investment program towards expansion of coverage area for wireless. TTL also plans to create a 3G capable network, to enable introduction of a range of wireless communication products and services.

Tata Teleservices currently enjoys a customer base of over 70,000 in Hyderabad, Vijayawada, Guntur and Visakhapatnam and deployed the latest technology. The company will extend services to six new towns before the end of the year.
