Bridge Link Planning
•
The wireless bridge antennas at both ends of the link must be
positioned with the same polarization direction, either
horizontal or vertical
Antenna Polarization — The wireless bridge's integrated
antenna sends a radio signal that is polarized in a particular
direction. The antenna's receive sensitivity is also higher for radio
signals that have the same polarization. To maximize the
performance of the wireless link, both antennas must be set to
the same polarization direction. The antenna polarization is
marked on the wireless bridge, as indicated in the following
figure.

Radio Interference

The avoidance of radio interference is an important part of
wireless link planning. Interference is caused by other radio
transmissions using the same or an adjacent channel frequency.
You should first scan your proposed site using a spectrum
analyzer to determine if there are any strong radio signals using
the 802.11a channel frequencies. Always use a channel
frequency that is furthest away from another signal.
If radio interference is still a problem with your wireless bridge
link, changing the antenna polarization direction may improve the
situation.
