SPECIFICATIONS
* Using IEEE 802.11a is no longer allowed outdoors in Europe where new DFS
(Dynamic Frequency Selection)requirements exist.
† Using IEEE 802.11a for bridging is not recommended in countries requiring
radar detection, as link speed and quality may be adversely affected due to
Dynamic Frequency Selection (DFS).
