FDMA stands for Frequency Division Multiple Access. It’s a channel access method used in telecommunications to divide the available bandwidth into frequency channels. Each channel is then assigned to a different user or communication stream, allowing multiple users to transmit simultaneously without interference. FDMA is commonly used in analog systems like traditional radio and television broadcasting. It’s one of the multiple access methods, with others including TDMA (Time Division Multiple Access) and CDMA (Code Division Multiple Access).
