Calculating number of channels per cell

Question

If total of 33 MHz of bandwidth is assigned to the certain cellular system that uses two 25 KHz Simplex channels in order to offer the full Duplex voice. Calculate number of channels that are available per cell if the system uses:

a)  4 cell reuse

b) 7 cell reuse  

Answer 1

Available bandwidth = 33 MHz

Channel bandwidth = 25 KHz

Total number of channels available = 1320 simplex channels.

a)  For 4 cell reuse

Number of channels per cell = 1320/4 = 330 channels

b)  For 7 cell reuse

Number of channels per cell = 1320/7 = 188 channels
