Two protocols in the channelization category of multiple access protocols:

  1. FDMA (Frequency Division Multiple Access) — divides the available bandwidth into fixed non-overlapping frequency bands, permanently allocating one band per station.

  2. TDMA (Time Division Multiple Access) — divides channel access into fixed time slots, with each station allowed to transmit only during its assigned slot.

(CDMA, Code Division Multiple Access, is also acceptable — it separates stations using distinct orthogonal codes rather than frequency or time.)
