Community Wireless: Interference

Part 18 RF Lighting: A Potential "Extinction Level Event" For Communications Users Of The 2.4 GHz Band
Fusion Lighting, Inc. uses microwave energy in a new, very high-efficiency lighting system, dubbed "RF [Radio Frequency] Lighting".
… A long term solution to interference issues in the 2.4 GHz band is to begin using equipment that operates in the 5 GHz band. In the US, there is a total of 300 MHz of spectrum available for license-exempt wireless devices at 5 GHz. 100 MHz of this spectrum is also ISM spectrum, with the potential of industrial devices being operated there also. But the other 200 MHz is "virgin" spectrum and reserved exclusively for communications.
