In some cases, the distance between the two locations to be connected exceeds the range of a single wireless link. This may be the case when the distance between the Access Points exceeds the radio range, or when obstacles exist in the line of site between the two Access Points
In these cases, the two end points can be connected by stringing together multiple Access Points, each of which has two WLAN modules. Because the intermediate Access Points often operate solely as relay stations, the operating mode of these Access Points is referred to as "relay mode".
Although LANCOM Access Points can run several P2P links simultaneously on each wireless module in addition to supporting wireless LAN clients, for performance reasons we recommended the use of LANCOM Access Points with two wireless modules for the relay stations.
