Wi-Fi and Radar Interference: The Challenges of DFS
2024-12-30
This article explores the interference issues between Wi-Fi networks and radar systems in the 5GHz band. Since Wi-Fi operates on unlicensed spectrum, proximity to airports or other radar-using facilities can lead to interference, causing device dropouts. Dynamic Frequency Selection (DFS) aims to mitigate this, but its implementation isn't seamless. DFS can cause brief Wi-Fi access point outages, impacting user experience. The article suggests avoiding UNI II band DFS channels near radar facilities or using newer APs and the UNI II extended band to minimize problems.
