5. Measurements have shown that the path loss exponent of an outdoor environment is equal to 3.2. The required minimum SIR for the AMPS systems (first generation cellular system with analog technology) is 18 dB (i) Find the smallest number of channel subsets we can use when deploying AMPS in such environment. (ii) If the total number of channels that the available spectrum can support is 1,200, how many channels each cell can have with equal allocation? ( iii) What...

(a) A cellular network system with a cluster size of 12 is designed to operate in a propagation environment with a pass loss factor of 3.5. Verify whether the designed system can be successfully deployed for practical use if a minimum signal to co- channel interference ratio of 18 dB is required for the satisfactory performance. Assume that the interference comes from the first-tier co-channel cells in the system which at the same distance from the mobile phone. (b) If...

A cellular system has 100 identical cells to cover a geographical area, and a total of 280 full-duplex voice channels are available in the entire system. The system uses the frequency reuse factor of 4, and that one full-duplex channel is shared among eight different users using TDM (Time-Division Multiplexing). How many simultaneous voice calls can be supported in the entire system? Assume that an equal number of voice channels are allocated to each cell.
