Wireless bridge is most afraid of encountering interference in use, no matter what interference will greatly affect its signal strength and transmission distance. So avoiding interference is a must. So what are the common disturbances? How to avoid?
Wireless bridge interference generally includes two types: external interference and internal interference. External interference refers to external obstacles, obstructions, etc., such as tall buildings, trees, etc. Internal interference is generally between devices of the same type, that is, mutual interference between bridges.
1, external interference
As mentioned above, there are many external disturbances, such as buildings, trees, etc. Especially the impact of buildings on wireless bridges is very large. During deployment and construction, it is necessary to avoid tall buildings as much as possible to ensure that there is no shelter and visibility between the transmitter and the receiver.
2, similar equipment interference
The interference of similar devices is also more, such as bridges with the same frequency, signal sources in the system, power supplies, etc. For this case, you can adjust the frequency of the wireless device, select a clean channel, or change the transmitter or receiver of the wireless device. The position of the device, pull the distance between devices.
How to determine if the bridge has received interference, you can judge through the monitoring screen. If there are packet loss, screen instability, clutter, black stripes, ripples, etc., if there is any indication that the equipment has been disturbed, you need to find out the reason one by one. .
It is not a device that interferes with wireless. Mobile, Unicom towers, walkie-talkies, wireless phones, etc. have no effect on wireless microwave equipment. When there are interference sources, the frequency of the equipment can be adjusted, or the installation can be installed at a position far away from the interference source. In this way, the interference to the wireless microwave equipment is greatly reduced.
