AirLive WHB-5854A Wireless Outdoor Bridge

Picture 24 Line-of-Sight (LOS)

If there is any obstacle in the radio path, it may still be a radio link but the

quality and the signal strength will be affected. Ensuring the maximum

clearance from objects on a path is important to locate the antennas and the

height. For the long-distance links, the radio signals might be lost partially due to

the non-LOS issue.

As we setup the radio path for the wireless bridge link, it needs to consider

these factors:

• Avoid any partial line-of-sight between the antennas.

• Be aware of trees that may be near the path or obstruct the path.

• Make sure there is enough clearance from buildings and there is no any

building or construction blocking the path.

• Check the land topology between the antennas using topographical maps,

aerial photos, or even satellite image data.

• Avoid a path that may have the temporary blockage due to the moving

objects, such as cars, trains, or aircrafts.

Note: For the wireless link less than 500 m, the IEEE 802.11a radio

signal will tolerate some obstacles in the path and may not even require a

visual line of sight between the antennas.
