 - FDMA (frequency division multiple access) is the division of the frequency band allocated for wireless cellular telephone communication into 30 channels, each of which can carry a voice conversation or, with digital service, carry digital data.
FDMA is a basic technology in the analog Advanced Mobile Phone Service (AMPS), the most widely-installed cellular phone system installed in North America. With FDMA, each channel can be assigned to only one user at a time. FDMA is also used in the Total Access Communication System (TACS).
The Digital-Advanced Mobile Phone Service (D-AMPS) also uses FDMA but adds
time division multiple access (TDMA) to get three channels for each FDMA channel, tripling the number of calls that can be handled on a channel.
