26. amount of interference Fixed Noise Floor Due to the popularity of the 2 4 GHz band there are many sources of interference This interference can sometimes be a problem due to the way 802 11 devices communicate Standard 802 11 communications uses a system called Clear Channel Assessment which means the radio will listen before transmission and if the channel is busy it will hold off regardless of the level of signal If the background interference is high due to other radio systems or noise you can raise the Fixed Noise floor to compensate The Channel Utilisation page can be used to identify excess noise interference Raising the Noise Floor will block out any receive signal levels below the value configured under Fixed Noise Floor on the Advanced Radio Configuration page The value must be entered as a negative dBm number and should be at least 8dB greater than the weakest RSSI of any connected modems otherwise communications may be lost E g if the interfering noise levels are around 80 dB you can raise the Noise floor to 70dB to block out any signals below making sure the RSSI levels of any connected modules are not below this Noise Floor as they will not communicate The Connectivity page can be used to determine what other systems are around and what their RSSI levels are After configuring the fixed noise floor confirm that the Channel Utilisation has dropped to a desirable level and where possible perform an iperf
