the result that they do not find each other. This stalemate situation can be
avoided with the appropriate "Channel selection scheme":
Thus it is recommended for the 5 GHz band that one central access point
should be configured as 'Master' and all other point-to-point partners should
be configured as 'Slave'. In the 2.4 GHz band, too, this setting simplifies the
establishment of point-to-point connections if the automatic channel search
is activated.

The following basic questions must be answered when designing wireless
links:
48
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.
MASTER ANTENNE
It is imperative that the channel selection scheme is configured cor-
rectly if the point-to-point connections are to be encrypted with
802.11i/WPA.
What antennas must be used for the desired application?
How must the antennas be positioned to ensure a problem-free connec-
tion?
What performance characteristics do the antennas need to ensure suffi-
cient data throughput within the legal limits?
