Telecom XT 3G Data Capabilities

Telecom Mobile operates 3G cellular networks at 850 and 2100MHz, with 3G data supported in both bands. As of 31 December 2010, Telecom had 2,192,000 mobile subscribers, 1,010,000 of which were on the XT network. Telecom also operates a legacy CDMA network which is not considered in this analysis.

As at 1 February 2011, Telecom was licensed for 1119 towers in the 850MHz band and 327 in the 2100 band. In most cases both bands are utilized from the same tower – the total number of towers operated being 1132. In 850MHz, towers have either 5,10, or 15MHz of spectrum licensed. At 2100MHz, all towers are licensed for 15MHz channels. Telecom uses Wideband CDMA (WCDMA), which requires a minimum channel sizes of 5MHz, so it is likely that in most cases Telecom are operating three 5MHz cells per band per tower.
