A wireless cellular system uses the GMS (TDMA). The bandwidth of each simplex channel is 200 kHz. The total bandwidth allocated is 200MHz . The signal-to-interference-ration required is 18 dB. Propagation path loss exponent n = 3 and omnidirectional antennas for the base stations are used.
1) Find the appropriate cluster size.
2) Find the total number of available duplex channel.
3) Find the number of duplex channels at each sell (single cell capacity)
4) Find the cluster size when 120-sectoring antenna is used.
5) Find the number of duplex channels at each sell with 120-sectoring antenna
6) Find the cluster size when 60-sectoring antenna is used
