BANGALORE: Bharat Sanchar Nigam Limited (BSNL) on Tuesday commissioned a state-of-the-art wireless mobile switching centre-based Code Division Multiple Access (CDMA) mobile network system for the city, with 35 towers. It allows subscribers to exchange SMS and connect to the internet at 144 kbps even while on the move.

It would be expanded in six months with additional towers to extend the coverage and meet additional demand. At present, the network with equipment from M/s ZTE Corporation, provided coverage for the entire urban area of Bangalore Telecom District, BSNL Chief General Manager, Karnataka Circle, S. Ramaganapathy said at the launch of the network here on Tuesday.

With this, BSNL could provide new connections and effect shifts without much delay in any part of the city, he said.

To improve rural tele-density, a CDMA main switching centre was also commissioned in Mangalore. This is the third CDMA main exchange in the State after Bangalore and Dharwad. With this, an extra capacity of 37,500 WLL (Wireless in Local Loop) lines had been generated in the State, he said.

Mr. Ramaganapathy commissioned three additional CDMA main switches with a capacity of 1.8 lakh lines and 240 additional CDMA towers. Supply of these equipment was expected by January 2007, he said.

To reduce the cable length of the existing telephone connections in the city, a part of the exchange could be removed and taken to a distant place and connected by optical fibre. Such Remote Switching Units (RSU) helped in improving the quality of performance by reducing the length of copper cable used, he said. Last year, 10 remote exchanges were opened with a total capacity of 20,000 lines at Kalasipalya, Shobha Apartments, Astra Zeneca, ABB, Basavanagudi DTO, RMZ, Rajajinagar 6th block, Malleswaram DTO, Thanisandra and Sultanpet.

Fifteen more RMUs were to be introduced in the Bangalore network during the current financial year and 50 more in the next, he said. Mr. Ramaganapathy said that BSNL proposed to introduce more RSUs and lay polythene insulated jelly-filled cable to eliminate fault-prone paper insulated copper cable from the Bangalore network. The improved network would enable provision of two lakh more broadband connections in the city, he said.
