Assignment:
In a GSM network the transmitted signal is narrowband with bandwidth B = 200 kHz centered at frequency f0 = 900 MHz. Each base station has an isotropic antenna that radiates the signal over a cell, which is a circular region with radius d = 3.5 km. Determine:
a) The required receive antenna gain to obtain a maximum attenuation of 90 dB over the entire cell.
b) The required receive antenna gain to obtain an average attenuation of 90 dB over the entire cell, by assuming that receivers are uniformly distributed over the cell.
