FDMA is a communication technique that divides the available frequency spectrum into multiple non-overlapping frequency bands. Each user is assigned a unique frequency band for transmitting and receiving data. This division ensures that different users' signals do not interfere with each other as long as the frequency bands are well-separated. FDMA is often used in analog radio communication and some early digital communication systems.
