Q3. (25 points) a. What is the largest benefit of cellular systems? b. Make frequency assignment to cells of 02 clusters of a hexagonal cellular network (figure 1)? (hints: Identify cluster, then apply reuse principle). c. What are factors that make throughput lower than advertised speed and vary widely within the cellular systems (at least 5)? f Note: fi.f.f..... are example frequencies. Figure 1 - A cellular network
