When purchasing a wireless bridge, it is estimated that most people will consult the transmission distance of these devices, but the actual application can not reach the expected transmission distance. What are the factors that affect the transmission distance of transmission equipment? Professional wireless bridge equipment and solution provider Feng Runda Xiao Bian organize some content.
First, device power: In the case of other factors are the same, the greater the power of the device, the longer the transmission distance, so you need to choose a device with greater power for long-distance wireless transmission.
Second, antenna gain: When other factors are the same, an antenna with a larger gain can transmit a longer distance. The gain antenna is equivalent to a signal amplifier, which can amplify the microwave signal transmitted by wireless transmission. Microwave signals travel farther.
Third, the smoothness of the transmission channel: When wireless transmission is performed, it must be ensured that the transmission channel is unblocked. This is a major premise of wireless microwave transmission. Because the microwave signals cannot pass through walls, mountains, forests, etc., it is best to use barriers or relays when encountering obstacles. Even if a small number of obstructions are faced, the transmission efficiency will be greatly reduced. Therefore, if you do not use the way of avoiding or relaying when obstructing objects, you will have to prepare for the worst transmission efficiency.
Fourth, the length of the feeder: The influence of the feeder on the transmission efficiency is small. After all, the feeder used in the normal situation will not be too long. However, because the feeder will cause more or less signal attenuation, use a shorter feeder as much as possible to better ensure transmission quality.
Fifth, the operating frequency of the wireless bridge: With the wireless monitoring, wireless transmission industry continues to grow, this type of equipment is almost everywhere, so the interference source of similar equipment has become rare. Therefore, the 5.8G equipment with strong anti-interference is better than the common 2.4G equipment. Under long-distance wireless transmission, the equipment with 5.8G working frequency has advantages over 2.4G.
The sixth, the installation location: wireless bridge can not be installed on the window, easy to cause plane interference, it will affect the transmission distance. Try to install the wireless bridge on the roof of the building. If you want to install it on the side of the window, you can build a bracket to install the device.
Basically, the factors that affect the transmission distance of wireless transmission equipment are the above points. I hope everyone will pay more attention to the points mentioned above when purchasing wireless bridges.
