Site Survey Page
The site survey function measures overall noise floor as well as in-band noise containing data packets. Noise is reported
in terms of average and peak dBm for the period tested. The user specifies duration of the test in minutes as well as the
antenna port. To run a site survey, the radio must be in Opmode OFF.
In this example the site survey function was performed for 1 minute on the vertical polarity. The lower band (5250 –
5340 Mhz) is reported to be relatively clean with a noise floor in the range of –97 to –98 dBm. The noise floor in the
upper band (5735 – 5835 MHz) is higher and ranges from –58 dBm (at 5735 Mhz) to –90 dBm (at frequency 5775 MHz.
In this example, channel 19 is the noisiest and should be avoided.
