Wireless network bridge, as the name implies, is a bridge that communicates between two or more networks through wireless transmission. The wireless bridge is positioned to transmit data wirelessly over a long distance, so its antenna is usually directional, and the transmission distance is much longer than that of a wireless AP.

 In practical applications, wireless bridges are usually connected by point-to-point or point-to-multipoint between the bridge and the bridge. When large obstacles are encountered during transmission, the obstacles can be bypassed by relaying. transmission.

Wireless AP, or wireless access point, is designed to convert a wired network into a wireless network, and is a communication bridge between the wireless network and the wired network. The wireless AP is located in the WLAN wireless signal coverage, so its antenna is usually omnidirectional, and the coverage is generally within 100 meters. 

In actual applications, a wireless AP can be used individually, and terminal devices (such as mobile phones and laptops) connect to the network through wireless signals connected to the wireless AP.
