Important regulatory information
The Enterprise Wi-Fi AP product is certified as an unlicensed device in frequency bands where it is not
allowed to cause interference to licensed services (called primary users of the bands).
Radar avoidance
In countries where radar systems are the primary band users, the regulators have mandated special
requirements to protect these systems from interference caused by unlicensed devices. Unlicensed
devices must detect and avoid co-channel operation with radar systems.
The Enterprise Wi-Fi APs detects and avoids functionality for countries and frequency bands requiring
protection for radar systems. The Enterprise Wi-Fi APs is qualified for ETSI/FCC DFS certification (see
Note ) for radar detection and avoidance as per the law.
Note
Country-specific limits apply, some bands require Dynamic Frequency Selection
(DFS). DFS bands operation subject to regulatory approval. Check Software
release notes for details.
Installers and users must meet all local regulatory requirements for radar detection. To meet these
requirements, users must set the correct country code during commissioning of the Enterprise Wi-Fi APs
equipment. If this is not done, installers and users may be liable to civil and criminal penalties.
