Site Survey Page
The site survey function measures overall noise floor as well as in-band noise containing data p ackets. Noise is repor ted
in terms of av erage and peak dBm for the period tested. The user sp ecifies 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 d Bm. The noise floor in th e
upper band (5735 – 583 5 MHz) is higher and ranges from –58 dBm (at 5735 Mhz) to –90 dBm (at frequenc y 5775 MHz.
In this example, channel 19 is the noisiest and should b e avoided.
