hide all2.5 GHz refers to the frequency band covering the range 2500-2690 MHz. The 2.5 GHz band is being distributed to mobile operators via an auction scheduled to take place in April/May 2010. The 2.5 GHz band is well suited for the launch of an LTE service, as it does not currently carry any other traffic, and as the LTE equipment currently supports only 2.5 GHz frequencies.

Churn rate refers to the percentage of yearly customer turnover, e.g. wireless subscribers are said to churn when they cancel their mobile service with their current wireless provider (and either move to a different provider or simply choose not to have a wireless service). TDC calculates churn by dividing the gross decrease in the number of customers for a period by the average number of customers for that period. The average number of customers for a period is calculated by adding together the number of customers at the beginning of the period, the number of customers at the end of each intermediate month, the number of customers at the end of the period and dividing the previous term by the number of intermediate months plus 2.
