Is the wireless bridge signal unstable? Solved like this

What happened?

The company has received a new project and installed multiple wireless bridges for the customer. The application experience was very good at first, but in recent days, it has been found that the data signal is strong and weak, very unstable, and it accepts the level and signal-to-noise ratio. All are high and low. After the staff of the enterprise went to see it on the spot, they found that two skyscrapers have been built between the communication base station and the customer station, and there are two big cranes on the roof. It is not clear whether such arrogance of the bridge data signal is affected by this hazard? In my opinion, during the entire process of applying wireless network equipment such as wireless bridges on the construction site, customers find that the problem of weak data signals is very common.

Under normal circumstances, customers use wireless bridges just to focus on their coordination capabilities and convenience, according to wifi network to transmit video surveillance system statistics, and then save the wealthy Internet. Then the problem is coming, wireless monitoring transmission

If you find that the actual effect of the wireless network bridge after installation is not very good, the data signal is not stable, or even there is no data signal,

What should I do? What is the original cause? Under normal circumstances, there are two key reasons and solutions

01 obstacle interference

The above examples often say that enterprises find that two skyscrapers have been built between the communication base station and the customer station, and there are two large cranes on the roof. This is a typical roadblock electromagnetic interference situation. Wireless image transmission

Sometimes when the wireless bridge equipment is built, the transmitting point and the receiving end are wide and unobstructed natural environments, but in the whole process of application, due to certain new projects, certain engineering buildings can be created in the middle. Or device, which blocks the transmission of data signals from the wireless bridge. Cause signal weakening or interruption. The solution at this time bypasses this kind of obstruction, and improves according to the countermeasures such as the security part of the mobile bridge, the relay mode, and the removal of the obstruction, so as to ensure the visibility and obstruction of the transmitting point and the receiving end. Wireless monitoring system

02 Angle deviation of wireless bridge

The wireless bridge is a point-to-point transmission mode. Only when the directional antenna is aligned with the angle, the signal can reach the JI A state. The farther the transmission distance, the higher the angle accuracy required.

If the network bridge is fixed and not firm at Anshi, causing severe temperatures such as wind, the wireless antenna part of the wireless bridge is loose, resulting in the inability to point the angle of view, and the data signal is the culprit of nature.

Therefore, in the safety process, people can first adjust the level gently, and then gradually adjust the direction to which direction the signal strength is stronger, if it is weaker, adjust to the opposite direction. After adjusting the level angle of view, adjust the up, down, left, and right angles of view. It is suggested that everyone must find a technically professional manufacturer to install the project.

03 Interference with same frequency equipment

The wireless bridge rate is divided into 2.4G wireless bridge and 5.8G wireless bridge. Like all wireless communications, the wifi network will also suffer from other radio waves. The frequency band in the IEEE 802.11b / g / n specification is 2.4GHz, and there are many machines and equipment in this frequency band during the work, such as the wireless intercom, radio HUA, microwave oven heating, mobile phone Bluetooth headset speaker, etc. that are often seen. In the 2.4GHz frequency band during operation, the situation of interfering with each other is serious.

When there are extremely strong electromagnetic fields around, the wifi network will undoubtedly be harmed. If there are a lot of data signal interference problems in the natural environment of the customer's wireless bridge application, but it is impossible to circumvent and reduce the problem of other machine equipment interfering with each other, it is proposed that the actual application scenario of the LIAN department can choose the 5.8GHz frequency band bridge The relative frequency in the 5.8GHz frequency band is purely without interference.

04 Wireless Bridge Quality

Wireless bridge quality issues, this is a basic point and an important point! The hardware configuration of the wireless bridge equipment is poor, and its transmission function will be greatly reduced after a period of application, and it will be seriously out of date and automatically restart. There are sales markets that do not clear out. Some stores plan their own wireless bridges for publicity. It is an exaggeration, or presents the transmission data in some idealized natural environment to customers, but in specific applications, it does not exceed the idealized natural environment. Transmission distance or network bandwidth.

Shenzhen Shenfang High-tech has devoted more than ten years to the product development and application of products in the wireless data transmission industry. The wireless bridge is made of JUN grade quality. It has strong anti-interference, good reliability, and is easy to integrate into the extreme natural environment of the suburbs.
