Engineers must look at 8 selections to the most suitable wireless bridge

There are a wide variety of wireless bridges on the market, and many engineering users do not fully understand the functions and features of wireless bridges. When choosing a wireless bridge, blindly obey the propaganda of the business, so that it is easy to pick inappropriate and high prices. product. This article summarizes the key points of the following 8 optional wireless bridges.

1 , working frequency band

Wireless bridges have two operating frequencies, 2.4 GHz and 5.8 GHz. The characteristics of the two bridges are different. In general, the 2.4G wireless bridge is a mainstream frequency band with good compatibility and good diffractive power, but its anti-interference performance is relatively poor. 5.8G wireless bridge frequency band is relatively pure, anti-interference ability is better, the transmission distance is far, but the diffraction ability is poor.

2 , the transmission rate

Wireless bridge transmission rate also has many options, such as ordinary 150Mbps and more efficient 900Mbps transmission, according to the user's transmission needs to be selected, the higher the proposed scenario to choose a higher transmission rate of the wireless bridge to ensure more transmission Stable, high definition.

3 , antenna

The antenna is an important part of the wireless bridge, used to transmit and receive wireless signals, there is no antenna, wireless bridge can not achieve communication. There are many kinds of antennas, such as omnidirectional antennas and directional antennas. The larger the antenna gain, the better the performance of wireless bridges. For long-distance transmission users need to choose a wireless bridge with stronger antenna performance.

4 , power supply

Wireless bridges are widely used in outdoor venues such as oilfield ports, forest construction sites, etc. In many cases, it is difficult to install electrical wiring. Generally, PoE-powered bridges are the best.

5 , security features

Wireless bridges, like wireless routers and wireless APs, also need to set passwords or encrypt wireless signals. Otherwise, there will be many terminal accesses that will affect wireless monitoring transmission.

6 , outdoor protection rating

Wireless bridges work outdoors, and the environment is changeable, such as thunderstorms, rain, snow, high temperature, dust, etc. Therefore, wireless bridges must have outdoor protection class standards, which can be waterproof, dustproof, lightning proof and high temperature resistant.

7 , performance stability

The stability of a wireless bridge is very important. If it works normally, it will crash for a while, and the rate will slow down. Then what wireless monitoring is it? Product stability is closely related to hardware, such as chips, motherboards, and memory. Of course, even if the wireless bridge hardware configuration is very good, users do not grasp the essentials during the installation process, but also there will be various situations such as performance instability.

8 , transmission distance

Wireless monitoring projects require different transmission distances. There are also many types of transmission distances for wireless bridges. Some transmissions range from 1 to 3 kilometers, some transmit from 3 to 5 kilometers, some transmit from 5 to 10 kilometers, and some transmit from 20 to 20 kilometers. Above kilometers, it must be determined based on the monitored transmission distance that the maximum transmission distance of the bridge should be greater than the monitoring transmission distance.
