To detect other access points within range, LANCOM Wireless Routers actively scan all of the available channels (just as a WLAN client would do to find an available access point). If another access point is active, the relevant information is stored to the scan table. Since this recording occurs in the background in addition to the access points' "normal" radio activity, it is called a "background scan".
Background scanning is mainly used for the following tasks:
- Rogue AP detection
- Fast roaming for WLAN clients
