Wireless access point

In computer networking, a wireless access point, or more generally just access point (AP), is a networking hardware device that allows other Wi-Fi devices to connect to a wired network or wireless network. As a standalone device, the AP may have a wired connection to a switch or router, but, in a wireless router, it can also be an integral component of the router itself. An AP is differentiated from a hotspot, which is a physical location where Wi-Fi access is available.

Although WAP has been used incorrectly to describe an Access Point, the clear definition is Wireless Application Protocol which describes a protocol rather than a physical device.
