3. 94 dBm avg 99 dBm 950 MHz peak 94 dBm avg 99 dBm gt 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 which will help you properly aim the SU at the AP to achieve maximum signal strength AP Search and SU Antenna Alignment 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 Once the SU is installed and aimed in the general direction of the AP it is time to perform an RSSI relative signal strength indicator test to determine the signal strength from the AP and to precisely align the SU antenna for maximum signal strength Trango Broadband Wireless User Manual M900S Rev A Page 32 Deployment Although it is possible to rely upon the subscriber units LEDs for alignment more precise RSSI readings are available from the command SSRSSI In conjunction with the RSSI command it is also useful to perform the APSEARCH command which will tell you which AP is providing an adequate signal at the location of the SU AP Search 1 Ensure AP is in opmode On 2 Run the apsearch command to verify which AP is providing the strongest signal strength In this example an AP is detected
