Wireless Access Point
Definition
A wireless access point (WAP) is a networking hardware device that allows other Wi-Fi devices to connect to a wired network. The WAP usually connects to a router as a standalone device, but it can also be an integral component of the router itself.
Why It Matters
WAPs are what create a wireless local area network (WLAN). They are the bridge between the wired network (like your internet connection from the router) and the wireless devices (like your phone and laptop).
Contextual Example
In a large office building, many WAPs are placed throughout the building to provide strong Wi-Fi coverage everywhere. As you walk through the building, your laptop seamlessly "roams" from one WAP to another.
Common Misunderstandings
- A WAP is not the same as a router, although most home "wireless routers" are combination devices that include a router, a switch, and a WAP.
- A simple WAP just provides wireless access; it doesn't assign IP addresses (that's the router's job).
