11.3.2.1  Radio Link Budget 

 
FM = Srx + Ptx + Gtx + FSL + Grx – Cl  
 
This fomula can be used to calculate any of the factors within. 
 
FM = Fade Margin (See chapter 11.2). 
Srx = Sensitivity of the receiver (dBm) (using +dBm instead of –dBm) 
Ptx = Transmitter RF output power (dBm) 
Gtx = TX Antenna Gain (dB) 
FSL = Free Space Loss (dB) (see above) 
Grx = Receiver (RX) Antenna Gain(dB) 
Cl = Cable/Connector Loss (dB) 
 

Note! 

To simplify, we use a general Cable/Connector loss, including both theTx and Rx site, of 

4dB. This is a high value for most installations, but still assumes a correct antenna cable 
installation.  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 

Example 5

.  Receiver sensitivity needed. 

 
Using Ex2 above and assuming 3dB antennas at each site: 

 

FM = Srx + Ptx + Gtx + FSL + Grx – Cl -> 
 
Srx = Ptx       + Gtx   + FSL        + Grx    – Cl    – FM -> 
 
Srx = 33dBm + 3dBd – 111.7dB + 3dBd – 4dB – 20dB = -96.7 dBm 
 

Example 6.

  Total antenna gain needed. 

 
Using Example 4 above. 40 km (24.8 miles) line of sight. 
 
FM = Srx + Ptx + Gtx + FSL + Grx – Cl -> 
 
Gtx + Grx = GA (Total Gain) -> 
 
FM = Srx + Ptx + FSL + GA – Cl -> 
 
GA = FM    +    Srx      -    Ptx       -   FSL      + Cl -> 
 
GA = 20dB + 110dBm - 33dBm    - 107.5dB + 4dB = -6.5 dB total 
 
Conclusion: 3dBd antenna gain is needed at each site to get approximately 
20 dB fade margin.
