In the Case of Flat Earth Propagation

Suppose the path loss is depicted by flat earth propagation model, then


L0 = $\displaystyle - 20 \log \left ( h_1 \right ) - 20 \log \left ( h_2 \right ) + 40 \log \left ( d \right )$  
  = 0 - 20 + 160  
  = 140   dB (15)
W = Pt + Gt + Gr - L0 - S / N -F +204  
  = 0 + 0 + 0 - 140 - 10 - 2 + 204  
  = 52   dB (16)

Here again, we assume that the maximum data rate equals to the channel bandwidth, so R = W = 105.2   bps .

End.
