As plans for a broadband wireless network begin to coalesce, network designers must give careful consideration to the physical infrastructure needed to provide maximum coverage and spectral efficiency. This paper walks readers through the most pertinent questions that go into this stage of planning. Specifically, the author considers which basic network topologies are appropriate for a given set of physical conditions and provides the characteristics that differentiate point-to-multipoint, point-to-point, and point-to-consecutive-point architectures.
