GSM uses narrowband TDMA, which allows eight simultaneous calls on the same radio frequency.
GSM was first introduced in 1991. As of the end of 1997, GSM service was available in more than 100 countries and has become the de facto standard in Europe and Asia.
One thing. CDMA allows 20 calls per channel, GSM only 8. Score 1 for CDMA.
