What should be paid attention to when choosing the right wireless bridge?

Wireless bridge, also known as CPE, can be used as a bridge for wireless networks, and is generally used in security monitoring and other application environments. It is often used in wireless monitoring sites such as scenic parks, station squares, port terminals, forest fire prevention, elevator communities, and tunnel sites.

So, under the increasingly popular wireless monitoring needs and influences, how to choose wireless bridge for wireless monitoring and transmission has become a major problem for engineering users. There are a variety of wireless bridges on the market, imported domestically produced, and expensive, allowing users to take a look.

In the end, how should engineering users choose the right wireless bridge?

Select wireless bridge should pay attention to the following points:

Look at the frequency band: 2.4GHz or 5.8GHz;

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

The user selects the frequency band of the bridge according to the actual application scenario. For example, the 5.8 GHz bridge is selected for remote operation in the field, and the 2.4 GHz bridge is selected for elevator monitoring. Some scenarios also require the use of two-band bridges to achieve the best results.

Wireless transmission rate;

The wireless bridge's transmission rate also has different choices. From 150Mbps to 900Mbps. The specific user can choose according to the engineering needs. For example, wireless high-speed wireless bridges need high-speed wireless video surveillance transmission.

Bridge antenna

There are 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 select a wireless bridge with higher gain and stronger performance to ensure transmission.

Power supply;

The working environment of wireless bridges usually involves some complex outdoor environments, such as forests, ports, and tunnels, so power supply is a more troublesome problem. Selecting a wireless bridge that supports POE network cables can solve this problem.

Bridge performance stability;

As with all wireless network devices, the performance of wireless bridges is also very 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.

Wireless bridge stability and product hardware have a direct link, including chip motherboards, components and so on. Of course, the installation of the bridge is also very important. The installation is good, and the performance of the bridge can be normal and stable.

Wireless transmission distance;

Users purchase wireless bridges to do monitoring projects, and the target transmission distance is different. Nearly 3-5 kilometers, 50-100 kilometers far from the range, the user should choose the appropriate wireless bridge according to the target transmission distance of their own projects.
