The first deployment of the new service, known as WLL CDMA, or wireless local loop code division multiple access, will replace existing radio services in remote areas of Queensland and NSW from January. But it is the longer-term implications of the move that will be pertinent to Telstra's bottom line. Telstra has long complained of the expense of building and maintaining its customer access - or copper wire - network in regional areas. Provision of these services, involving ditch digging and cable rolling, can cost tens of thousands of dollars for a single connection, compared to $1500 or so to deploy a CDMA wireless local loop service. The difference in maintenance cost is believed to be even more marked. ADVERTISEMENT Wireless local loop services are now preferred to more expensive fixed line services in countries such as India, where there is a low density of telephone services. Telstra Countrywide spokesman Chris Zipf said that initially, the WLL technology would be deployed in rural and remote Australia, particularly in extended zones - parts of Australia too remote for copper wires. At present these areas use existing radio technology, called digital radio concentrator systems (DRCS), but the new service will provide Telstra with cost savings. Mr Zipf said: "DRCS is microwave radio technology used to provide voice services to customers located in areas too sparse for the use of copper cables. The technology uses chains of radio towers or masts to pass radio signals to a radio structure installed on a customer's property." CDMA WLL could now match the requirements of a standard telephone service, Mr Zipf said. It would also provide features such as call waiting and calling number display, which were not available with DRCS. The telecommunications giant has undertaken three trials of WLL technology with its equipment supplier, Nortel Networks, on King Island in Bass Strait and in Toowoomba and Minto in Queensland, over the past six months. Telstra also has the option to provide faster data services over CDMA after the recent launch of a high speed upgrade to its network called 1xRTT. Telstra touts the service as a junior third-generation mobile technology which will provide data speeds about as fast as a normal 56Kb per second fixed line modem. australianit.news.com.au
