User’s Manual AW2400-SPEC Operational summary The AW2400-SPEC is a tool that allows you to investigate sources of RF interference in the 2.4 GHz band and to make better decisions about how to configure your AvaLAN wireless network. Leveraging the RSSI (Received Signal Strength Indication) capability from the AvaLAN AW2400xTR, this unit inexpensively provides a browser-interfaced RF spectrum analysis capability with appropriate frequency range and sensitivity for site survey applications.

AW2400-SPEC User’s Manual Sample Spectra Here is an example of a relatively quiet environment. If your scan shows that there is low in-band noise on all channels, you will probably want to leave your AvaLAN radio in auto-frequency selection mode, allowing it the opportunity to change channels as needed should interference arise later. This next example shows the result of operating the AW2400-SPEC in close proximity to a Bluetooth and three WiFi sources.
