The new standard is supposed to support TKIP and AES encryption and uses 802.1x (port based authentication).
The new standard is supposed to support TKIP and AES encryption and uses 802.1x (port based authentication). Answer: I've heard of confusing 802.1x and 802.11x, but this is the first I've heard about 802.1i!
802 refers to the series of IEEE Local and Metropolitan Area Network standards. 802.1 refers to standards that specify architecture and interworking techniques that apply to all kinds of LANs. 802.3 refers to Ethernet LAN standards. 802.11 refers to wireless LAN standards.
Each new project is assigned a letter. When a standard is published, it is carries the series designation, the project letter and the year in which it was ratified. For example:
- 802.1x-2001 defines Port Access Control for all kinds of LANs
- 802.11b-1999 defines wireless LANs in the 2.4 GHz band
- 802.11g-2003 defines Higher Data Rate Wireless LANs in the 2.4 GHz band
- 802.11i-2004 defines security enhancements for all wireless LANs
By the way, 802.11x is just really bad shorthand for all 802.11 standards. This letter hasn't (yet) been assigned to an IEEE project, but when it is, confusion will reign.
