IEEE 802.11:
- IEEE 802.11 stands for wireless LAN that was ratified by the Institute of Electrical and Electronics Engineering.
- There are many 802.11 standards for wireless LAN technology in the IEEE 802.11. The different 802.11 standards all share some common characteristics.
- Basic service set (BSS) is a fundamental building block of 802.11 architecture. The BSS also known as Access Point (AP).
- Every wireless station in 802.11 wants to associate with an access point before it can send or receive network layer data.
