The system gain is part of the link budget and known as Maximum Allowed Path Loss (MAPL).
A practical implementation of a link budget is described in 'How to > Link budget'
The System gain of a radio link is calculated as per the following:
| T |
Power of the transmitter in dBm
|
| L1 |
Transmitter line loss in dB |
| A1 |
Transmitter antenna gain relative to an isotropic antenna (dBi) |
| A2 |
Receiver antenna gain relative to an isotropic antenna (dBi) |
| L2 |
Receiver line loss in dB |
| R |
Receiver sensitivity where the voltage is used as provided by a 0 dBd dipole antenna with a impedance of 50 ohm. |
The system gain MAPL is expressed in dB:
MAPL = (T - L1 + A1 + A2 - L2) - R
