Frequency Division Multiple Access

As the name implies, Frequency Division Multiple Access (FDMA), utilizes Frequency Division Modulation (FDM) to separate the given spectrum into individual analog bands or channels. A simplified view of how this is done can be seen in figure 1 below. Each of these channels is then able to facilitate communication for a single user. According to (Goleniewski, 2007) each FDMA cell is able to facilitate about 60 users, which is very a low number by current standards.
