Distributed

The distributed network, also referred to as a localized network, involves
establishing the network as being independent of other networks that the
wireless company may have. The distributed network is ideal for a wireless
company that has only a few markets that are geographically disbursed,
such as in New York and San Francisco.
The advantages of a distributed network lie in its simple implementation.
The distributed architecture can also be folded at a later time into a
regional or centralized approach.
Of course, the disadvantage with the distributed approach lies in the
issue of duplication and the lack of economies of scale for implementing and
operating the network. Also, there is the distinct possibility that the networks
will implement services differently and no commonality will exist between the data or even the voice networks unless standard practices and
procedures for design and operation are implemented.
The typical implementation of a distributed packet network layout is
shown in Figure 7-4.
