Before revision: Infrastructure Cellular networks work by only reusing radio frequencies (in this example frequencies f1-f4 ) in non adjacent cells to avoid interference The critical advantage that modern cellular networks have over predecessor systems is the concept of frequency reuse allowing many simultaneous telephone conversations in a given service area.
