a). Vodafone decides to use a digital TDMA scheme which can tolerate a Signal-to-Interference Ratio of 17dB in the worst case. Find the optimal value of the path lost exponent for an omnidirectional antenna; assuming i=3 and j=2. Assume that there are six co-channel cells in the first tier, and all of them are at same distance from the mobile. Use suitable approximations. b). The effective aperture of a 144.0cm-diameter parabolic reflector antenna is 6m of the physical aperture area. Prove that the gain in dB can be determined, if the frequency is estimated to be 10GHz.
