Offering connectivity in those locations where there is no possibility of developing a wired infrastructure is one of the challenges that network manufacturers have to face. There are devices used to making wireless communications at large distances, called wireless bridges, and in order to use them, there are certain aspects needed to be taken into account.
What is a Wireless Bridge?
Long-distance Wireless Communication
Wireless Bridges enable the transmission of information through different points or locations in which the deployment of installations using fiber or copper wired infrastructure is usually not feasible. Wireless bridges use radio link connection, which refers to any connection between telecommunications devices through electromagnetic waves.
Requirements and Good Practices
For a radio link connection to be stable, there should be a direct line of vision between the devices connected. The line of vision is not an actual line: there is a region called the Fresnel Zone in which there should be no elements such as buildings, objects, trees, or any other element that may weaken the signal. If the devices are located on a roof, make sure the roof is not weakening the radio link connection.
Types of Wireless Bridges
1. PtP solutions
There are two kinds of Wireless Bridges: first, we have the Point-to-Point devices (PtP). These are formed by two radio devices with antennas that create a wireless connection between two geographically separate locations. These radio devices usually include directional antennas because they tend to be facing each other, and it is not necessary for the emission beam to have a wide opening. One of the devices will work as Access Point (AP) and the other one as client (CPE).
2. PtMP solutions
The second kind of Wireless Bridges are called Point to Multipoint (PtMP). These Wireless Bridges have a sector antenna that works as Access Point or Base Station, and two or more devices that act as Client (CPE). In this case, the access point will have an antenna that can cover Wireless connection on an area with a certain degree of opening, the clients (CPE) will have to be within this sector for the radio link connection to be stable.

Radio links are a very good option for those environments where wired installation is not possible. The use of good practices and the correct dimensioning according to the characteristics of the radio link will result in the highest possible stability. Visiotech, wholesale distributor of radio links, offers a wide range of devices that allow the transmission of information between different points where the deployment of copper or fiber wired infrastructure is usually not feasible.
