In 2020, the FCC adopted standards that allow for the use of WiFi in the 6 GHz band. A portion of the frequencies authorized overlap with frequencies utilized for fixed point-to-point microwave, the most common microwave band utilized for the backhaul of public safety land mobile radio systems. The premise for this authorization was that WiFi 6 systems authorized for indoor use should not interfere with fixed microwave systems. Now WiFi 6 devices have hit the market, and the interference the public safety industry was so worried about is here. And, with no recourse when interference cases do occur, the problem is here to stay.

Key takeaways from this session include:

1. Review of technical and regulatory consideration that demonstrate why interference is a risk
2. Proven example of WiFi 6 interfering with public safety microwave
3. Options when interference is discovered
