Introduction to wireless bridge selection method in wireless monitoring project

Wireless bridge devices can be divided into many models according to their power, device performance, and effective transmission distance. Therefore, when setting up a wireless monitoring system, it is very important to select the appropriate wireless bridge device according to the site environment. Today we will specifically understand the selection methods of wireless bridges in wireless monitoring projects.

1, transmission distance

The target transmission distances required by different users are different. There are 1-5 kilometers in the near future and 50-100 kilometers in the far distance. When purchasing the wireless bridge, users must inform the equipment manufacturer of the transmission distance in advance, so that the equipment supplier can prepare for you. Model wireless bridge.

2, power supply mode

The working environment of a wireless bridge usually involves some complicated outdoor environments, such as forests, ports, tunnels, etc., so power supply is a more troublesome problem. Selecting a wireless bridge that supports POE cable power supply can solve this problem well.

3, the frequency band

The wireless bridge can be divided into a 2.4 GHz bridge and a 5.8 GHz bridge according to the frequency band. The bridges of the two frequency bands have their own advantages and disadvantages. The 2.4GHz wireless bridge is the mainstream frequency band, and the compatibility and diffraction capability are better, but the anti-interference ability is poor. The 5.8 GHz frequency band is relatively pure, the anti-interference ability is better, the transmission distance is also far, but the diffraction ability is poor.

The user selects the frequency band of the bridge according to the actual application scenario. For example, when the remote field is working, the 5.8 GHz bridge is selected, and the elevator monitor selects the 2.4 GHz bridge. In some scenarios, bridges in two frequency bands are also required to perform well.

4, transmission rate

There are also different options for the transmission rate of the wireless bridge. From 150Mbps to 900Mbps. Specific users can choose according to engineering requirements. For example, if you need high-definition wireless video surveillance transmission, you should choose a wireless bridge with higher wireless rate.

5, the antenna

There are also several types of antennas for wireless bridges, including omnidirectional antennas and directional antennas. The gain of the antenna is closely related to the transmission performance of the wireless bridge. Users with long-distance transmission needs to choose a wireless bridge with higher gain and higher performance to ensure transmission. This specific can consult the equipment supplier to understand.

6, performance stability

As with all wireless network devices, the performance stability of wireless bridges is also important. If the bridge is stuck for a while, lost packets for a while, and disconnected for a while, it is impossible to establish a reliable and stable monitoring transmission.

The stability of the wireless bridge is directly related to the product hardware, including the chip board, components and so on. Of course, the installation of the bridge is also very important, the installation is good, the performance of the bridge can be played normally and stably.

Grasping the above points can better ensure the stable operation of the wireless monitoring system. Of course, for users, these factors are not well understood, so it is extremely important to choose a professional and serviced equipment supplier. Tengyuan Zhituo is such a company. Each product data of the company is obtained after repeated tests for 6 months. The performance of the products is industrial-grade wireless transmission quality, which can fully meet the application of users in various environments. Our professional technology and after-sales team allow users to have peace of mind when setting up and using wireless monitoring systems.
