Antenna alignment for P2P operations

The precise alignment of the antennas is of considerable importance in estab-
lishing P2P connections. The more central the receiving antenna is located in
the "ideal line" of the transmitting antenna, the better are the actual perform-
ance and the effective bandwidth ³. If the receiving antenna is outside of
this ideal area, however, significant losses in performance will be the result
·.

The current signal quality over a P2P connection can be displayed on the
device's LEDs or in the LANmonitor in order to help find the best possible
alignment for the antennas.
