enhancements to the MAC Layer to counter the some of the weaknesses of WEP. It
incorporates stronger encryption techniques than the original Wi-Fi Protected
Access (WPA), such as Advanced Encryption Standard (AES).
The original WPA, which can be considered a subset of 802.11i, uses Temporal Key
Integrity Protocol (TKIP) for encryption. WPA2 is backwards-compatible with
products that support the original WPA
IEEE 802.11i / WPA2 was finalized and ratified in June of 2004.
802.11k
IEEE 802.11k is a developing IEEE standard for wireless networks (WLANs) that
helps auto-manage network Channel selection, client Roaming, and Access Point
(AP) utilization. 802.11k capable networks will automatically load balance network
traffic across APs to improve network performance and prevent under or over-
utilization of any one AP. 802.11k will eventually complement the 802.11e quality
of service (QoS) standard by ensuring QoS for multimedia over a wireless link.
802.1Q
IEEE 802.1Q is the IEEE standard for Virtual Local Area Networks (VLANs)
specific to wireless technologies. (See
http://www.ieee802.org/1/pages/802.1Q.html .)
The standard addresses the problem of how to break large networks into smaller
parts to prevent broadcast and multicast data traffic from consuming more
bandwidth than is necessary. 802.11Q also provides for better security between
segments of internal networks. The 802.1Q specification provides a standard
method for inserting VLAN membership information into Ethernet frames.
A
Access Point
An access point is the communication hub for the devices on a WLAN, providing a
connection or bridge between wireless and wired network devices. It supports a
Wireless Networking Framework called Infrastructure Mode.
