FDM vs. FDMA. Frequency Division Multiplexing, or FDM, is a multiplexing technique for the physical layer that allows multiple low bandwidth signals to share the same high bandwidth frequency range.It is achieved by allocating a smaller frequency range to each signal that is using the same channel.ummary: 1. FDM is a physical layer multiplexing technique, while FDMA is a data link layer access method. 2. Using FDM to allow multiple users to utilize the same bandwidth is called FDMA.
