What is a wireless bridge?

A wireless bridge is a hardware component used to connect two or more network segments. You can use a wireless bridge to transparently connect computer(s) in one room to computer(s) in a different room when you could not, or did not want to run an Ethernet cable between the rooms.

Wireless bridge devices work in pairs (point-to-point), one on each side of the "bridge". However, there can be many simultaneous "bridges" using one central device (point to multipoint).

Many wireless routers and wireless access points offer either a "bridge" mode or a "repeater" mode, both of which perform a similar function. Wireless routers, access points, and bridges are available that utilize each of the commonly used wireless frequencies. The frequency bands for these wireless standards can be used license-free in most countries.

During bridge setup, the wireless devices used for the bridge must be set to the same service set identifier (SSID) and radio channel.
