The results will display signal levels for each frequency in intervals of 4MHz for each channel. Select the channel with lowest signal levels.

Note: Each Channel is 20MHz wide.

When selecting a channel, make sure to review 10MHz above and 10MHz below. As an example, Ch 5 covers frequencies 5806 to 5826. This channel is not clear. Frequency 5812 has a noise level of -77dBm. This noise level will interfered with your signal resulting in poor performance. Chanel 6 is a better choice.

Channel Planning

Based on the results of the site survey at each end of the link, choose a channel with the lowest noise floor. A clean spectrum is essential for proper performance. It is recommended to maintain a 10dB fade margin or separation from the noise floor for best performance.

RSSI Command and Antenna Alignment

Once the site survey is completed, you are ready to install your radios. Typically it is best to install the AP first. To properly align the radios, use the built-in RSSI tool to achieve maximum signal strength.

1.Ensure SU is in Opmode “ON”

2.Connect to the SU.

3.Login and type the command rssi. As you read the RSSI, move the antenna in the horizontal and vertical planes until the maximum RSSI reading is achieved

4.If it is not possible to receive an adequate RSSI reading, it may be necessary to reorient the SU (up/down, left/right), to increase the output power of the AP, or to move the SU to a location with better line-of-sight conditions to the AP.

5.Once you are satisfied with the RSSI reading, tighten down the SU in the optimum position.
