D-AMPS differs from AMPS technology by using Time Division Multiple Access (TDMA) technology as its media access technique. TDMA splits each 30 kHz–wide AMPS channel into three additional channels.
This triples the number of cellular phone channels available under AMPS. D-AMPS is an easier upgrade path from AMPS than Global System for Mobile Communications (GSM), which also uses TDMA technology but in an incompatible format.
