WatchGuard XTM wireless devices adhere to 802.11n, 802.11b and 802.11g guidelines set by the Institute of Electrical and Electronics Engineers (IEEE). When you install an XTM wireless device:
Before you set up your wireless XTM device, it is also a good idea to consider environmental factors, which apply to the installation of WatchGuard wireless devices. For example, you can use a wireless site survey tool to better understand your current environment and existing wireless signals before you add a new XTM wireless device. Based on the results of your site survey, and the requirements of your wireless clients, you can plan which wireless modes and channels to use. You will also know more about the level of wireless noise in your environment, and can consider other factors, such as the position of walls, that can affect wireless signal range.
