Both ends must share the same key; otherwise theremote peer will ignore the request. To use WDS discovery, both ends must equipped with this feature containingshared secret. For example, the remote one is also an OWL800.Each WDS interface has its own RF (Radio Frequency) settings; normally, valid combination of RF parametersconfiguration would like the following table. However, the available values of each item will be affected by the RFregulation which is configured in AP's RF settings.¾ Band: Select appropriate wireless band or disable if the service is not required; bands available for WDSlinks are 802.11a, 802.11b, 802.11g and 802.11b+802.11g.Note: The second radio in the system is designed for building WDS links. WDS links are used as backhaul orpoint-to-point bridges. WDS links do not service AP clients. 11a (5.725~5.85GHz) is used by the 2 nd radio moduletypically in order to avoid the channels of 11b/g (2.4GHz) used by the first radio module for serving clients.However, 11b and 11g are still available to the 2 nd radio (WDS) in case the administrator determines to use 11b/gfor building WDS links base on their deployment condition.¾ Channel: Select an appropriate channel from the list to correspond with the network settings.Note: Depending on the region (US, EU, or JP) the product is built for shipping to, the number of selectablechannels varies. For example, there are only 11 channels selectable in 2.4G band for the products made to ship tothe US market, and there are 13 channels selectable in 2.4G for the product made to ship to the EU market. Thereare different firmware versions with different selectable channel-lists for different regions.
