Cingular Wireless will shut off its analog TDMA cellular network in 2008 according to CEO Stan Sigman’s keynote speech at TelecomNext. Even though the aging network still has two years of life, over 95% of Cingular voice traffic is already on the newer digital GSM network.

Cingular has been working on the TDMA to GSM transition since its merger with AT&T Wireless in 2004. The transition requires customers to upgrade handsets, typically at their expense.
