consider a cellular network with 64 cells. Each hexagonal cell has an appropriate area of 10Km2. Total no of radio channels allotted for the network is 336. Find the total number of channels of the network, if

a) N = 4

b) N = 7

c) N =12, where N denotes cell reuse

Total number of cells = 64. Each cell area = 10 km2.

The total area covered by the cellular network is, 64 X 10 = 640 km2.

It is given that the total available channels in the network = 336.

• (a) For N = 4, the available channels in a cell = 336/4 = 84

  • Total channels = 84 X 64 = 5,376 channels.

• (b) For N = 7, the available channels in a cell = 336/7 = 48

  • Total channels = 48 X 64 = 3,072 channels.

• (c) For N = 12, the available channels in a cell = 336/12 = 28

  • Total channels = 28 X 64 = 1,792 channels.
