Telecom New Zealand says it will close down its TDMA network on 31 March next year. The firm has gradually been transferring customers off the network, which was switched on in 1987, with 400,000 moved over the past 18 months. There are now just 83,000 subscribers still using the outdated system, with the bulk of Telecom’s cellular customers using its more modern CDMA network, which launched in 2001.
Meanwhile, more details have emerged of Telecom’s plans to roll out CDMA EV-DO Revision A technology. The CDMA Development Group (CDG) reports that the first upgraded sections of the network will be switched on in Auckland at the end of this year, with deployments in other major cities such as Wellington, Christchurch, Hamilton and Dunedin following by the middle of next year. The entire CDMA network will have been upgraded by the end of 2007. EV-DO Rev. A boosts average download speeds to around 800kbps, with uplink speeds averaging around half that. The peak rates are 3.1Mbps and 1.8Mbps respectively.
