Access Point
An access point or wireless accesspoint is a comparatively small and connecting network device and serves as an interface for wireless communication in offices or companies. An access point, often referred to as an AP, not only looks like a router, but works almost exactly like one. A local area network can be set up with a WLAN access point (WiFi AP). If the WiFi AP is connected to a router, switch or hub via an Ethernet cable, it can send out a WiFi signal and supply areas that were previously not or poorly supplied with WiFi.
