Once you are familiar with the basic operation of the radios you are ready for deployment in the field.  The deployment process 
consists of the following steps:  

•  Site Selection 
•  Site survey at MU and RU sites 

•  MU installation 
•  RU installation and antenna alignment 

•  Link test  

Proper site selection for your MU will help ensure a successful deployment.   Site selection will depend on a wide variety of 
factors, but from the radio’s performance standpoint, please consider the following: 

•  Path from MU to RU should provide unobstructed line-of-sight (LOS), thus it is advisable to place MU as high as 

possible on a tall building or tower. 

•  Ethernet cable limit is 100 meters from Ethernet device (router, switch) to radio. 
•  Radios should never be deployed without proper grounding. 

•  Consider nearby sources of interference that could degrade the performance of the radio.  Mount radios as far from 

sources of interference as possible. 

The radios provide an on-board site survey tool which measures the average and peak noise levels on any given channel. 
 
To use the survey tool, the radio must be in Opmode “OFF.”  The survey can be performed for any specified amount of 
time (in seconds), and for specific channels or for all channel/antenna polarization combinations. 
 
Prior to performing the site survey, place the radio in the installation spot, and aim the radio in the desired direction. 
 
The survey command will display the average and peak noise floor for each channel as well as average and peak RSSI 
received during the same period for 802.11 packets. 
 
Users may run any of the following variations of the survey command: 
 
survey                               

display noise floor for current channel based on 10 second scan. 

survey [<sec>]                   

display noise floor for current channel  for  period <sec> 10..3600 seconds 

survey <sec> all                      

display noise floor for all available channels where  <sec> = period per channel 

survey <sec> [<ch#> [..]]              display noise floor for selected channels (max 4) where <sec> = period per channel 
                                          

 

<ch#> = channel number
