  1. Transmisor - Receptor Potencia del transmisor [dBm] - Pérdidas en el cable Tx[dB] + Ganancia de la antena Tx [dBi] - Pérdidas en espacio libre [dB] + Ganancia de la antena Rx [dBi] - Pérdidas en el cable Rx[dB] = Margen – Sensibilidad del Rx[dBm]

  2. Potencias en el sistematransmisor-receptor

  3. Pérdidas en el espacio libre (Free SpaceLoss) FSL (dB) = 20 log d + 20 log f - 147,5 FSL (dB) = 20 log d (Km) + 20 log f (GHz) + 92,4

  4. Horizonte radioeléctrico entre dos antenas dH = d1 + d2 = 3.57 ( + )

  5. Ganancia de antenas parabólicas Potencia del transmisor - Pérdidas en el cable tx + Ganancia de la antena tx - Pérdidas en espacio libre + Ganancia de la antena rx - Pérdidas en el cable rx = Margen – Sensibilidad del rx
