It is a pretty broad question and I am assuming we are talking about WiFi (the most common WLAN technology). So, in pretty high level terms =
There is a WiFi access point. This consists of a radio transmitter / receiver that is connected to an ethernet switch - usually there is a router attached to that switch also - and frequently that router is connected to the internet.
There is a WiFi interface on the ‘user device’ (laptop, phone, etc). This consists of an radio transmitter / receiver that is connected to an ethernet switch inside the device which is connected to the TCP/IP stack on the ‘user device’.
So … there is a protocol between the two radios for connecting them to one another … usually this starts with the Access Point broadcasting its presence, and the User Device selecting it to connect. Once the User does this, the protocol goes through several more steps for establishing & maintaining the connection. This is where any authentication & encryption might occur.
Once the connection is established, it appears to the ethernet switches on either end that they are connected to each other (which they are via the radio connection).
Everything after this is pretty much like normal Local Area Network / Ethernet / IP operations.A WLAN is a wireless computer network that links two or more devices using wireless communication. WLAN uses high frequency radio waves to form a local area network within a limited area. It allows users to access wider internet, while maintaining network connection. They are easy to install and use.WLAN transmit data from one point to other, by using nodes and access points.
An access point is station or a device or a router, through which data is transmitted and received. These APshelps in connectingusers within the network or multiple users linked to this AP or helps in interconnecting WLAN and wired network.
Nodes are connectionpoints that receive, create, store or send data along the distributed network routes. These have capability for transmitting data to other network nodes.
