Dynamic Frequency Selection (DFS)

802.11a APs sold in Europe use a technique called Dynamic Frequency Selection (DFS) to automatically select an operating channel. During boot-up, the AP scans the available frequency and selects a channel that is free of interference. If the AP subsequently detects interference on its channel, it automatically reboots and selects another channel that is free of interference.
