What is a wireless bridge? In fact, literally, you can guess a score. Of course, it is a bridge for wireless connection. However, this understanding is incomplete. So how does a wireless bridge define it? Take a look at this article.

What is a wireless bridge? The Wireless Bridge is designed for point-to-point interconnection of remote data transmission using wireless microwave. It is a storage and forwarding device that implements lan interconnection at the link layer. It can be used for wireless networking between fixed digital devices and other fixed digital devices with a distance of 20 km) and a high speed of up to 11 mbps. The Wireless Bridge has three working modes: point-to-point, point-to-point, and relay connection. It is especially suitable for long-distance high in cities and whether bidirectional amplifiers are used.

Wireless Bridge

What is a wireless bridge? A wireless bridge can be used to connect two or more independent network segments, which are usually located in different buildings, the distance is several hundred meters to dozens of kilometers. Therefore, it can be widely used for interconnection between different buildings. In addition, according to different protocols, wireless bridges can be divided into 802.11b or 802.11 in the GHz band and 802.11a wireless bridges in the GHz band.

In the absence of high obstacle peaks or buildings), a pair of fast networking and temporary networking for field operations. The distance depends on the environment and the antenna, and now 7km point-to-point microwave connection. A 27dbi oriented antenna can achieve 10km point-to-point microwave connection. The 12 DBI oriented antenna can achieve 2km point-to-point microwave connection. One pair of wireless bridges that only implement link layer functions are transparent bridges, the targeted antenna with routing and other network-layer functions and the 24dbi network can implement real-layer interconnection between devices in different networks. It can also be used as a layer-3 Bridge.

A wireless bridge is usually used outdoors and is mainly used to connect two networks. It is impossible to use only one Wireless Bridge. More than two wireless bridges must be used, and AP can be used independently. The Wireless Bridge has high power, and the maximum transmission distance is about 50 km. It has strong anti-interference ability and does not have its own antenna. Generally, it is equipped with a parabolic antenna for long-distance point-to-point connection.
