Chapter 6: Point- to- point connections

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.

rectly if the point-to-point connections are to be encrypted with 802.11i/WPA.

6.1Antenna alignment for P2P operationsIt is imperative that the channel selection scheme is configured cor-

The precise alignment of the antennas is of considerable importance in estab- lishing a P2P path. The more central the receiving antenna is located in the "ideal line" of the transmitting antenna, the better is the actual performance and the effective bandwidth ￿. If the receiving antenna is outside of this ideal area, however, significant losses in performance will be the result ￿.
