A wireless bridge allows a wireless connection between two network end-points, those end-points can be: buildings, CCTV cameras, networks or just about any IP device that you want to link.
A wireless bridge is often used to span buildings and provides a more economical method of network connectivity than laying a cable.
Unlike an access point which serves multiple end points or devices in a 30 – 360 degree spread, a wireless bridge is purely directional between point A and point B. They can be used over both short (just a few meters) and long (over many miles) distances, making them ideal for a variety of connectivity solutions.
