![]() In some areas of London, for example, high-performance leased lines can be prohibitively expensive. The most common answer is that you need a physical link, which rules out a VPN connection, and a wired link isn’t possible, either. And, since communication over a wireless bridge is always done between two transceivers (as opposed to one emitter that broadcasts a signal to any receiver that is willing to “listen”), these wireless links are point-to-point links. Since they transmit and receive signals through air, using antennae or optical receptors, wireless bridges are sometimes referred to as free-to-air (FTA) bridges. This way, two IP networks can be connected through a wireless link. They use antennae – usually highly directional antennae – to send and receive wireless signals on one side, and connect to regular IP networks on the other side. Wireless bridges use radio (RF) signals in the microwave (MW) or optical/laser (free space optics – FSO) links to interconnect two access points. ![]() You may also find a wireless bridge referred to as a WiFi bridge. Wireless bridges can be used to interconnect networks such as those in buildings in the same campus, in shipping and manufacturing sites in neighbouring districts or nearby towns, offices across the street from one another and so on. In fact, today we’re going to talk about the other option: wireless bridges.Ī wireless bridge is a solution (specifically, a set of devices) that allows you to connect two networks, or more accurately two network segments, over a wireless channel – sort of like a bridge, if you will, hence the name. ![]() You’d think the answer is obvious – you run a cable between them – but that’s not always an option. It’s a very common problem: companies with multiple sites, as well as companies with a single site but multiple buildings, or located in remote areas, frequently have to solve it. If we were to run a contest for the most deceptively simple question in the networking world, “who do you interconnect two networks?” would be one of the most likely winners.
