Leveraging the RSSI (Received Signal Strength Indication) capability from the AvaLAN AW5800xTR, this unit inexpensively provides a browser-interfaced RF spectrum analysis capability with appropriate frequency range and sensitivity for site survey applications.

This next example shows a strong in-band signal (in this case caused by another AvaLAN radio operating in the vicinity on Channel 5.

They will not affect the reliability of data transmission, but if severe, they could degrade the data rate a bit because of sub-packet retransmissions. 5.8 GHz Channels Channel Frequency - MHz Channel Frequency - MHz Channel Frequency - MHz 0 Auto Mode 20 5767.7083 40 5809.3750 1 5728.1250 21 5769.7917 41 5811.4583 2 5729.6875 22 5771.8750 42 5813.
