When point-to-multipoint networks are connected to the same backbone network and designed to allow the same frequencies to be re-used in different areas, the result is a cellular network. The backbone network might be either wired or wireless. Figure 3-4 shows a diagram of a cellular network that includes three point-to-multipoint networks.
The advantages of using a cellular architecture are as follows:
Expands the geographical coverage area
Increases the network capacity
Leverages the use of network resources
Provides redundant end user coverage
Allows roaming ...
