A one-dimensional cellular system has 80 channels at its disposal. The modulation scheme employed requires a minimum SIR of 14 dB. Determine the minimum distance between radio access ports if the channel assignment failure rate is not to exceed 1% and the required area capacity is 5 mobiles/km. Assume that the path loss increases as the α = 2.5 power of the distance.
