Link Margin provides a measure of all the parts of the RF path that impact the ability of two systems to communicate. The basic equation looks like this:

 

EIRP (dB) = TxP + TxA – TxC

 

Link Margin (dB) = EIRP – FPL + (RxS + RxA – RxC)

Where:

TxP = Transmitter output power (dBm)

 

TxA = Transmitter antenna gain (dBi)

 

TxC = Transmitter to Antenna coax cable loss (dB)

 

FPL = Free Path Loss (dB)

 

RxS = Receiver receive sensitivity (dBm)

 

RxA = Receiver antenna gain (dBi)

 

RxC = Receiver to Antenna coax cable loss (dB)

This is a complex subject and requires more information than is presented here, Quatech recommends at reviewing the subject and evaluating any system at a basic level.

It is then possible, with a combination of the above items and an understanding of the application demands, to achieve a link quality optimized for the application and host design. It is important to note that this is established with a combination of hardware selection, design choices and configuration of the radio.
