A wireless access point (WAP) is a networking device that allows wireless-capable devices to connect to a wired network. It is a hardware device that creates a wireless local area network (WLAN) and connects to a wired router, switch, or hub via an Ethernet cable. An access point can be a standalone device with a wired connection to a router, or it can be an integral component of a wireless router.

An access point is different from a hotspot, which is a physical location where Wi-Fi access is available. It is also different from a wireless ad hoc network, which uses a connection between two or more devices without using a wireless access point.

Access points can be used to extend the range of a wireless network through the use of repeaters, which amplify a radio signal, and reflectors, which only bounce it. They can also be configured as root or non-root bridges to join multiple networks.

Wireless access points have advantages over wireless routers in larger businesses and venues where many APs are required to provide an internet connection to support thousands of users. Access points can handle over 60 simultaneous connections each, and users can roam freely from room to room without experiencing network interruptions.

In summary, a wireless access point is a device that creates a wireless local area network and allows wireless-capable devices to connect to a wired network. It is different from a hotspot and can be used to extend the range of a wireless network. Access points are commonly used in larger businesses and venues where many APs are required to provide an internet connection to support thousands of users.
