What is the flow of the wireless bridge setup?

Before we understand what the steps of the wireless bridge setup are, let's take a look at what a wireless bridge is.

As the name implies, it is a bridge of wireless networks, which can bridge communication between two or more networks (a wireless bridge is also a branch of a wireless AP). In addition to the basic features of the above-mentioned wired bridge, the wireless bridge works in the 2.4G or 5.8G free wireless license band, and is more convenient to deploy than other wired network devices.

Its transmission standard often uses 802.11b or 802.11g, 802.11a standard, and the data rate of 802.11b standard is 11Mbps. 802.11b can usually provide actual data rate of 4Mbps to 6Mbps while maintaining sufficient data transmission bandwidth, while 802.11 g, 802.11a standard wireless bridges have a transmission bandwidth of 54Mbps, and the actual data rate can reach about 5 times that of 802.11b.

In the manufacturer's propaganda description, although many wireless APs or wireless routers also have bridge functions, and are also called wireless bridges by manufacturers, the wireless bridges we talk about in this article strictly mean that the transmission distance is 1-20. More than a kilometer of product, rather than bridging within a few hundred meters like a normal wireless AP or wireless router.

A communication connection is established between two points (such as headquarters and branches, network centers, and cells). From the customer's needs and actual exploration conditions to the transmission mode, and the appropriate wireless bridge settings, there are the following transmission methods:

(1) visible between two points of AB; no obstacle blocking; no electromagnetic interference, or small interference; the distance between two points of AB meets the requirements of communication distance of bridge equipment.

It can be transmitted directly in a point-to-point manner: a wireless bridge is placed in the A building, and a directional antenna is placed on the top; a bridgeless platform is placed in the B building, and a directional antenna is placed on the top. After the wireless bridges of the two places are connected to the local antenna through the feeders, the wireless communication between the two points can be quickly established. The wireless bridges are connected to the network switches in each place through the super five twisted pairs. The two networks can be connected together.

(2) The two points between AB are not visible, but they can be indirectly visible through a C building. And AC two points, between the two points of BC to meet the requirements of bridge equipment communication.

We use the relay method, and the C building serves as a relay point. Each of the ABs is placed with a bridge and directional antennas.

The C point options are:

Place a bridge and an omnidirectional antenna. This method is suitable for situations where the transmission bandwidth is not high and the distance is relatively close;

Two bridges and two directional antennas are placed. The advantages of this method are: long transmission distance, strong signal, bandwidth and transmission quality. (Depends on customer needs and actual conditions).
