Wireless bridge signal instability? It's certainly OK to solve this problem~

Author: admin time: November 22, 2019 source: unknown
Summary: wireless bridge

What's going on?

The company is new one Several projects are installed for customers wireless bridge At the beginning, the application experience was very good, but in recent days, we found that the data signal was sometimes strong and weak, and it was very unstable. The receiving level and signal-to-noise ratio were both high and low. Enterprise staff went to see on the spot, found that the communication base station and the customer station have been built between two skyscrapers, and the roof has two A large crane, do not know whether the bridge data signal so arrogant by this harm? In my opinion, in the whole process of using wireless network equipment such as wireless bridge in the construction site, the problem of weak data signal is very common.

In the case of wireless bridge, it only focuses on the convenience and application ability of customers wifi Network to transmit video monitoring system statistics, thus eliminating the rich Internet. So here comes the question...,

If it is found that the actual effect of the wireless bridge installation is not very good, the data signal is not stable, and even there is no data signal decisively,

What to do? What is the cause? In general, the reasons and solutions are as follows

01 Obstacle interference

It is often said in the above article that the enterprise has found that two skyscrapers have been built between the communication base station and the customer station, and there are two skyscrapers on the roof two A large crane, that is to say, the typical situation of electromagnetic interference of roadblocks.

Sometimes when the wireless bridge equipment is built, the transmitting point and receiving end are wide and unrestricted natural environment. However, in the whole application process, some engineering buildings or equipment must be created in the middle of the project to block the transmission of wireless bridge data signal. Cause the signal to weaken or interrupt. At this time, the solution bypasses this kind of obstruction, and improves according to the installation position of mobile bridge, relay mode, removal of obstructions and other countermeasures, so as to ensure the visibility and blocking of transmitting point and receiving end.

02 Angle deviation of wireless bridge

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

If it is in the installation of the bridge fixed is not solid, resulting in strong wind and other bad temperature, wireless bridge wireless antenna parts loose, leading to the angle of view can not point, data signal natural culprit harm.

Therefore, in the whole process of installation, people can adjust the level gently first, and then gradually adjust to which direction the signal strength is stronger, and then adjust to the opposite direction if the signal strength is weak. After the leveling angle of view is adjusted, the upper, lower, left and right angles are adjusted. It is suggested that all of us must find a technical professional manufacturer to construct and install the project.

03 Interference of CO frequency equipment

Frequency division of wireless bridge 2.4G Wireless bridge and 5.8G Wireless bridge, the same as all wireless communication, wifi Networks also suffer from other radio waves. IEEE 802.11b/g/n The frequency band in the standard work is 2.4GHz There are a lot of machines and equipment in this frequency band, such as wireless walkie talkie, wireless telephone, microwave oven heating, Bluetooth headset speaker 2.4GHz Frequency band, so the condition of mutual interference is serious.

When there is a strong electromagnetic field around, wifi There is no doubt that the network will be harmed. If there are many data signal interference problems in the natural environment of the customer's wireless bridge application, but there is no way to avoid and reduce the problem of mutual interference between other machines and equipment, it is proposed to choose according to the actual application scenarios 5.8GHz Frequency band bridge, 5.8GHz The relativity of frequency band is purely non-interference.

04 Wireless bridge quality

Wireless bridge quality problem, this is the most basic point is also the most important point! The hardware configuration of wireless bridge equipment is poor, and its transmission function will be greatly reduced after a period of application. In some serious cases, there will be old disconnection and automatic restart. In fact, it is not ideal to use the wireless network to deliver data to customers in the market.

Shenzhen Shenfang High Tech Co., Ltd. has been committed to the R & D and application of products in wireless data transmission industry for more than ten years. The wireless bridge is built with military grade quality, which has strong anti-interference performance and good reliability, and is very easy to integrate into the extreme natural environment in the suburbs.
