Consider a hexagonal cellular deployment with omnidirectional base station antennas and reuse cluster size N = 3. a) Depict the worst case co-channel interference situation on the forward link, considering the first two tiers of co-channel base stations. Use the supplied hex paper.
b) Determine the set of exact distances from the first two tiers of co-channel base stations to the target mobile station.
c) Calculate the worst case carrier-to-interference ratio, consid- ering the first two tiers of co-channel base stations and compare with the case when only the first tier co-channel base stations is considered. What is the difference in decibel (dB) units between the two cases?
d) Considering the first tier of co-channel interferers and N = 3, compare the worst case carrier-to-interference ratio, , on the forward and reverse links.
