FDMA is sensitive to the frequency-selective fading inherent to multipath environments when narrow subbands are used for a single modem type, and puts high demands on hardware if modems with different passbands are used.
Contention-free protocols can be further subdivided into time-division multiple access (TDMA), which assigns different time slots to users, frequency-division multiple access (FDMA), in which users transmit in different frequency bands, and code-division multiple access (CDMA), where orthogonal (pseudo-random) codes are used between users.
