1. Obstruction
How can the wireless bridge signal be lower?
Generally, when the wireless bridge is installed, the signal strength is recommended to be greater than 30dbm. If the signal is too weak, the stability will be degraded and the data transmission will be affected. Then how does the wireless bridge find the signal is weak after installation? What is the original cause? Today, Feng Runda came and told everyone about this knowledge.
The signal is very weak Look at the next whether the wireless bridge between the transmitter and the receiver is visible, whether there is an obstruction, if any, you can use the relay method or both sides of the high, avoiding the middle of the obstruction.
2, the angle is wrong
It may be that the angle between the transmission and reception of the wireless bridge is not right. Most wireless bridges use dual-polarization antennas to transmit. Therefore, the antenna angle of the wireless bridge must not only be aligned horizontally, but also the pitch angle must be correct. Well, it is guaranteed to communicate within its signal range.
At this point, you can adjust the antenna angle when entering the system to see the signal strength, gently adjust the first level, the signal strength is stronger, and then slowly adjust to that direction, if weaker, adjust in the opposite direction. After adjusting the horizontal angle, finely adjust the upper and lower angles.
3, the installation location is wrong
Wireless bridges cannot be installed on windows, which can cause plane interference. As far as possible, wireless bridges are installed in relatively open positions on the roof. If they are to be installed near windows, a bracket can be set up to install the device.
4, the transmission distance is too far
If the transmission distance is too far, and the wireless bridge itself cannot transmit such a long distance, or the transmission power is not enough, the signal is certainly not good. In this case, it is necessary to replace a wireless bridge device that has long distance or greater transmit power.
5, inappropriate bridge
Generally, in a downtown area or a downtown area, 2.4G wireless bridges are not recommended because there is more interference at the same frequency, and 5.8G wireless bridges should be replaced at this time. The frequency band is relatively clean and interference-free.
6, the antenna is not suitable
Whether it is a built-in antenna or an external antenna, there is gain. The greater the gain, the longer the transmission distance. If no problems are found in other areas, the signal is still weak, and it may be an antenna gain problem. The antenna with a larger gain needs to be replaced. If a wireless bridge with a built-in antenna at a short distance is used, it will be replaced with an internal antenna with a larger gain.
