How to solve the problem of unstable wireless bridge signal and stuck monitoring screen?

Case analysis:

The unit has taken on a new project and installed several wireless bridges for users. At first, the user experience was very good, but in recent days, it has been found that the signal is strong and weak, very unstable, and the reception level and signal-to-noise ratio are also fluctuating.

After the company personnel went to the site to inspect, they found that two tall buildings were being built between the base station and the user station, and there were two large tower cranes on the top of the building. I wonder if the network bridge signal's capriciousness was affected by this?

In fact, it is quite common for users to find weak signals when using wireless devices such as wireless bridges at construction sites. In general, users use wireless bridges to value their flexibility and convenience, and transmit video surveillance data through wireless networks, eliminating the need for wired networks.

So the problem is, what should we do if we find that the Wireless Bridge installation does not work well, the signal is unstable, or even there is no signal at all? What is the cause? In general, there are several main reasons for this situation.Wifi 5 Outdoor Wireless Ap

01. Obstacle interference

In fact, as mentioned in the previous case, the company found that two tall buildings were being built between the base station and the user station, and there were two large tower cranes on the top of the building, which is a typical phenomenon of obstacle interference signals.

Sometimes, when installing wireless bridge equipment, the transmitting and receiving ends may be in an open and unobstructed environment. However, during the use process, due to the needs of some projects, some buildings or facilities may be established between them, which hinders the transmission of wireless bridge signals and causes signal weakening or interruption.

The solution at this point is to avoid these obstacles and improve them by moving the installation position of the bridge, relay mode, removing obstacles, and other measures to ensure that the transmitting and receiving ends are visible and unobstructed.

02. Wireless bridge angle deviation

Wireless bridge is a point-to-point transmission method. Only when the directional antenna is aligned with the angle can the signal reach its optimal state. The farther the transmission distance is, the higher the accuracy of its angle is required.

If the bridge is not firmly fixed during installation, resulting in adverse weather such as strong winds, loose antenna positions of the wireless bridge, and misalignment of the angle, the signal will naturally be affected.

Therefore, during the installation process, we can first adjust horizontally and slightly. When the signal strength is stronger, we can slowly adjust in that direction. If it is weaker, we can adjust in the opposite direction. After adjusting the horizontal angle, fine tune the upper and lower angles. It is recommended that everyone find a professional manufacturer for construction and installation.

03. Interference from Same Frequency Equipment

Wireless bridge frequencies are divided into 2.4G wireless bridge and 5.8G wireless bridge, and there are many devices operating in this frequency band, such as frequently seen walkie talkies, wireless phones, microwave ovens, and Bluetooth earphones, all operating in the 2.4GHz frequency band, so mutual interference is relatively serious.

When there is a strong magnetic field nearby, the wireless network will definitely be affected. If there are a large number of signal interference issues in the user's wireless bridge usage environment, but it is also recommended to avoid and reduce interference between other devices wirelessly, it is recommended to choose a 5.8GHz frequency band bridge based on the actual application environment, which is relatively pure and non-interference free.

04. Wireless Bridge Quality

The quality issue of wireless bridges is the most fundamental and important point! The hardware of wireless bridge devices is poor, and after using them for a period of time, their transmission function will be significantly reduced, and in severe cases, there may be phenomena such as disconnection and automatic restart.

In the market, it is not ruled out that some merchants may exaggerate their wireless bridges or display some ideal transmission data to users, but in practical applications, it is impossible to achieve the transmission distance or bandwidth in the ideal environment.
