Chapter 6: Point- to- point connections

6 Point-to-point connections

LANCOM Wireless access points serve not only as central stations within a wireless network, they can also operate in point-to-point mode to bridge longer distances. For example, they can provide a secure connection between two networks that are several kilometers apart—without direct cabling or expensive leased lines.

The behavior of an access point when exchanging data with other access points is defined in the "Point-to-point operation mode".

Off: The access point only communicates with mobile clients

On: The access point can communicate with other access points and with mobile clients

Exclusive: The access point only communicates with other base stations

In the 5 -GHz band, the automatic search for vacant WLAN channels can lead to several simultaneous test transmissions from multiple access points, with the result that they do not find each other. This stalemate situation can be avoided with the appropriate "Channel selection scheme":

Master: This access point takes over the leadership when selecting a free WLAN channel.

Slave: All other access points will search for a channel until they have found a transmitting Master.
