Aviat’s new service offering helps you quickly find and address interference issues to protect your network. Aviat’s FAS (Frequency Assurance Software) offers sophisticated, well-tested monitoring and analysis of unlicensed 6 GHz—and can trigger corrective action to protect link stability.
Aviat, Ameren, EPRI unlicensed to licensed radio interference field test report
In response to the FCC announcement of the expanded use of unlicensed equipment into the 6 GHz band, Aviat Networks, along with Ameren (utility operator with large Aviat install base) and EPRI (non-profit research & development organization), agreed to execute a series of field tests to determine potential impact unlicensed equipment could present into an existing microwave radio path.
RLAN (Radio Local Area Network), a regulator’s technical term for Wi-Fi, got a new update in 2020, with FCC opening a 1,200 MHz of channel bandwidth between 5.925 GHz and 7.125 GHz. This operation of unlicensed devices across the current 6 GHz band enables the next generation of wireless broadband called Wi-Fi 6E.

The FAS expert system is designed to use several rules to determine if interference is happening in any of the radio links registered for monitoring in the application. As part of the overall design and implementation efforts, Aviat has conducted many laboratory tests that were intended to determine the effects of different types of interferer signals in point to point microwave links. These tests allowed not only for a better understanding of how the performance parameters of the radio link were being affected in the presence of interference; but also to the creation, validation, and refinement of the rules that were implemented in the FAS expert system. As we understand more about the impact interferers can cause to the radio links, the expert system rules will be refined, and new rules will be added. This process will be part of the overall expert system learning and evolution.
