We learned that an ideal multiple access protocol has FOUR desirable

characteristics, describe them.

Explanation:

1.- Very experienced technology and easy to implement.

2.- Rigid resource management and unfit for variable traffic flows.

3.- Requires antenna duplexer for duplex transmission.

Duplex is a term used in telecommunication to define a system that is capable of maintaining two-way communication, sending and receiving messages simultaneously.

4.- Normally FDMA is combined with multiplexing FDD.

FDMA (acronym in English for Frequency Division Multiple Access) is a multiplexing technique used in multiple communication protocols, both digital and analog, mainly radio frequency, and among them in mobile phones of GSM networks.

FDD (Frequency Division Duplexing in English) designates a duplex method in the environment of wireless telecommunications and over certain wired networks.
