An access point (AP) is a device that connects to a wired network. It can be a router, bridge, or switch, or it can simply be known as an AP (access point). The access point works very similarly to an amplifier but not just for extending WiFi. It takes the bandwidth from the router and projects the signals to the designated area, extending the coverage over an extended distance.
Wireless bridging is a technology developed to extend network connectivity via infrared or microwave transmission between physically isolated locations where a cable connection is not viable. The wireless network bridge joins different segments of networks together over a wireless channel by enabling two access points to connect to each other over long distances using their radios. By deploying the wireless network bridge, you can cover a larger physical area with higher throughput, allowing you to build a point-to-point (P2P) or point-to-multipoint (P2MP) connection between cross-building offices, neighboring districts, and nearby towns. Wireless bridges are very similar to access points, but they are designed to serve different purposes.
