Quizplus · Accepted Answer

The first PCS technology used time division multiplexing (TDM) and specifically a variation called time division multiple access (TDMA). TDMA divides the available frequency spectrum into time slots, allowing multiple users to share the same frequency band by transmitting in different time slots. CDMA, GSM, and D-AMPS are different types of cellular technologies that were developed later.
