In this example of a survey on the vertical polarization for 2 seconds for each 5 MHz portion of spectrum, the largest amount of energy is detected at frequency 2415 MHz.

The asterisks (****) indicate the highest avg amount of energy detected and corresponds to the number of yellow colored LEDs lit.

Note: The survey also covers spectrum outside of the operational range of the radio.

Once the site survey is completed you are ready to install your radios. It is recommended that APs be installed first. The reason for this is that the SU has a built-in RSSI tool that will help you properly aim the SU toward the AP to achieve the maximum signal strength.

Once the AP is installed and aligned in the correct general direction, it is time to install the SU. The hardware installation of the SU is identical to the AP, including considerations for line-of-sight, cable distances, cable type, weather sealing, and grounding.
