FDMA (frequency division multiple access) is the oldest communication technique used in broadcasting, land-mobile two-way radio, etc. It begins with a band of frequencies, which is allocated by the FCC (Federal Communications Commission). This band of frequency is further divided into several narrow bands of frequencies, where each frequency, also known as channel, is used for full-duplex communication. The communication link is maintained in both directions, either in the frequency domain or in the time domain. This is governed by two basic modes of operations known as the Frequency Division Duplex (FDD) and Time Division Duplex (TDD). These topics, along with FDMA spectrum management and its attributes, are presented in this chapter.
