Wireless Bridge Link Planning 6 - 5
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.
