Weather Conditions
When planning wireless bridge links, you must take into account
any extreme weather conditions that are known to affect your
location. Consider these factors:
•
Temperature — The wireless bridge is tested for normal
operation in temperatures from -33°C to 55°C. Operating in
temperatures outside of this range may cause the unit to fail.
•
Wind Velocity — The wireless bridge can operate in winds up
to 90 MPH and survive higher wind speeds up to 125 MPH.
You must consider the known maximum wind velocity and
direction at the site and be sure that any supporting structure,
such as a pole, mast, or tower, is built to withstand this force.
•
Lightning — The wireless bridge includes its own built-in
lightning protection. However, you should make sure that the
unit, any supporting structure, and cables are all properly
grounded. Additional protection using lightning rods, lightning
arrestors, or surge suppressors may also be employed.
•
Rain — The wireless bridge is weatherproofed against rain.
Also, prolonged heavy rain has no significant effect on the
radio signal. However, it is recommended to apply
weatherproof sealing tape around the Ethernet port and
antenna connectors for extra protection. If moisture enters a
connector, it may cause a degradation in performance or even
a complete failure of the link.
•
Snow and Ice — Falling snow, like rain, has no significant
effect on the radio signal. However, a build up of snow or ice
on antennas may cause the link to fail. In this case, the snow
or ice has to be cleared from the antennas to restore operation
of the link.
