  In most deployments, 

1/8 Cyclic Prefix

 will provide a high quality, higher throughput 

link. In cases with severe multi-pathing or obstructions, 

1/4 Cyclic Prefix

 may give 

better overall results. 

Procedure for setting the Cyclic Prefix 

3.  Set the 

Cyclic

 

Prefix

 on the Configuration => Radio page of both the BHM and the 

BHS to 

1/8

 before deployment. 

Important!  

The 

Cyclic

 

Prefix 

must be set the same on both the BHM and the BHS. If they 

don’t match, the BHS will not register to the BHM. 

4.  During installation use Link Tests to confirm link quality per standard installation and 

alignment procedures. 

5.  If a Link Test shows low throughput or efficiency, consider changing the Cyclic Prefix 

to 

1/4

 on 

both

 the BHM and the BHS along with other standard installation 

troubleshooting procedures such as re-aiming, off-axis aiming, changing location, 
raising or lowering the height of the radio, adjusting 

Transmission Power

 up or 

down, or identifying and mitigating sources of interference.
