GSM (Global System for Mobile Communications)
GSM is an open, nonproprietary system that is the dominant cellular technology throughout the world today. GSM uses a variation of the Time Division Multiple Access (TDMA) protocol. Data is digitized and compressed, then sent down a channel with two other streams of user data, each in its own time slot. It operates at either the 900-MHz or 1800-MHz and 1900-MHz frequency band.
Compare to CDMA.
