Briefly explain the concepts of frequency reuse in the cellular system [4 marks] (a) (ii having a radius of 0.64km and a co-channel reuse factor of 12 determine the distance for the nearest co-channel cell1 for a cell that [hint: frequency reuse ratio, q r [6 marks] (b) the first generation cellular advanced mobile phone service (amps) system is allocated 25mhz band with 21 control channels for one direction communication at 800mhz range. the total bandwidth required for communication is 50mhz. the frequency separation between the uplink and downlink is 45mhz. the guard band is 40khz and each simplex channel is 30khz determine the total numbers of channels within the system [5 marks] determine whether the amps system is simplex, half-duplex or duplex [5 marks] 11 (iii) 352 at 880.560mhz find the transmission frequency of a mobile subscriber unit transmitting on channel 352 consider the base station transmits control information on channel
