Utep: Take you to the wireless bridge in 3 minutes
A wireless bridge is actually a bridge to a wireless network. Two wireless networks are connected by wireless bridging, which is often used to replace optical fibers and network cables for network data transmission of several hundred meters, several kilometers or even tens of kilometers. The advantages of using wireless bridges for wireless transmission are: no need for cumbersome wiring, reduced construction difficulty, saving manpower and material resources, and reducing project costs.

First, the classification of wireless bridges
At present, there are mainly three types of electromagnetic wave bands operating on the bridge according to the bridge.
1, 2.4G wireless bridge
2.4G wireless bridge is a wireless bridge using 2.4GHz microwave working frequency band, usually used for medium and short distance transmission, such as elevator monitoring wireless transmission, indoor coverage, park monitoring transmission, etc. The transmission rate is 150Mbps and 300Mbps.
For example, Utech's new 2.4G 300M elevator monitoring dedicated bridge CP2-300 is mainly used for wireless transmission of elevator monitoring internal video, abandoning the traditional anti-stretching dedicated cable solution, and transmitting data by wireless. A lot of wiring work is saved, which effectively shortens the construction period and reduces the construction cost. The product features a unique one-button pairing technology with IP65 protection for a variety of complex elevator environments.

2. 5.8G wireless bridge
The 5.8G wireless bridge is a wireless bridge that uses the 5.8 GHz microwave working frequency band. It is usually used for medium and long distance transmission, and has the characteristics of long transmission distance and strong anti-interference ability. The 5.8G microwave frequency band is the same as the 2.4G microwave frequency band, and is free to apply for the wireless license band.
The new 5.8G 300M outdoor monitoring dedicated bridge CP5-300 adopts 11n technology, which can provide up to 300Mbps wireless transmission rate and transmission distance of 3-5km. The product adopts the design of industrial grade waterproof and dustproof plastic shell, which can easily adapt to various harsh environments outdoors. Built-in 14dBi dual-excited plate antenna greatly enhances wireless transmission performance and stability. This product is widely used in medium and short distance video transmission and data transmission, such as: scenic spots, factories, terminals, construction sites, parking lot wireless monitoring.

3, dual frequency bridge
The dual-frequency bridge adopts the 2.4G and 5.8G microwave dual working frequency bands, which has the characteristics of long transmission distance and high transmission rate. According to different designs, the transmission rate of dual-frequency bridges ranges from 600 Mbps to 1800 Mbps, and is generally used in applications where transmission bandwidth is high.
Second, wireless bridge network transmission mode
In different scenarios, wireless bridges mainly have three usage modes: point-to-point transmission, point-to-multipoint transmission, and relay transmission.
Point-to-point transmission is a transmitting end and a receiving end networking mode, which solves the scene of point-to-point linear transmission, typical scene elevator monitoring application.
Point-to-multipoint transmission is a networking mode of one transmitting end and multiple receiving ends, and each receiving end can transmit signals with the transmitting end. Application scenarios such as construction sites, mining areas, etc. need to monitor scenes in multiple places.

Point-to-multipoint transmission networking
The relay transmission is a networking mode of two receiving ends and one relay station, and is applied in a scene with an occlusion in the middle. Wireless bridge transmission requires visible and unobstructed between the receiving end and the transmitting end, but sometimes the field environment is not ideal, and the transmission line may be blocked by obstacles. If you do not want to change the line, you can only take the relay. transmission.
Third, the installation and setup of the wireless bridge
The wireless bridge is used by the transmitting end and the receiving end in pairs. When installing the wireless bridge, be careful that the transmitting end and the receiving end are aligned with each other, and there is no obstruction between the transmission paths, and it is kept stable. When installing, it can be installed on the monitoring rod, iron frame or wall according to the actual environment. Common fixing parts can use U-bolts, screws, cable ties, hoops, etc. For elevator monitoring, it is usually installed at the top or bottom of the elevator car.
Application of wireless bridge in elevator monitoring
Different brands of wireless bridges will have corresponding settings interface. However, from the overall development trend, the setting of wireless bridges is moving toward simplification, intelligence, and digital visualization. For example, the UTP wireless bridge products can realize one-button fast matching of digital switches, and the setting process is quite simple. The following is a quick pairing method.
1, one-to-one matching method
1) Dial one bridge to the “master AP†and the other bridge to the “slave APâ€;
2) Short press the “Digital Switch/Reset†button, each time you press the digital tube value will increase by one (0-9-AF cycle)
3) Set the paired bridge to the same value to match successfully.
2, one-to-many matching method (within one pair of eight)
1) Dial one bridge to the “master AP†and the other bridge to the “slave APâ€;
2) Short press the “Digital Switch/Reset†button, each time you press the digital tube value will increase by one (0-9-AF cycle)
3) Set the paired bridge to the same value to match successfully.
Fourth, the application of wireless bridge
Wireless bridges have been widely used in elevators, scenic spots, highways, oil fields, mining areas, forest fire prevention, port terminals and other monitoring sites. As an important wireless monitoring transmission equipment, the wireless bridge is related to the performance and correct use of the entire wireless monitoring system. Therefore, users should know more about wireless bridges and choose reliable brand products.
In order to comply with the market demand trend, Youpupu has launched the intelligent 2.4G 300M elevator monitoring dedicated bridge and 5.8G 300M outdoor monitoring dedicated bridge, welcome to ask.
