1. Show that the reuse distance
for the channel assignment algorithm associated with hexagonal cells that is described in Section 15.2.
2. Consider a cellular system with diamond-shaped cells of radius R = 100 m. Suppose the minimum distance between cell centers using the same frequency must be D = 600 m to maintain the required SIR.
(a) Find the required reuse factor N and the number of cells per cluster.
(b) If the total number of channels for the system is 450, find the number of channels that can be assigned to each cell.
(c) Sketch two adjacent cell clusters and show a channel assignment for the two clusters with the required reuse distance.
