Airport. The marketing name used by Apple for the wireless networking supported by Macintosh computers (iBook, PowerBook, etc). 'Airport' cards and basestations are based on the 802.11b wireless standard; 'Airport Extreme' equipment is based on the newer and faster 802.11g.
802.11a. An IEEE wireless standard that was defined subsequent to 802.11b. It operates in the 5GHz radio frequency range - meaning that it is incompatible with the 802.11b and 802.11g standards.
802.11b. The original IEEE wireless standard. It operates at 11Mbit/s in the 2.4Ghz radio frequency range.
802.11g. A more recent IEEE wireless standard, operating at up to 54Mbit/s in the same radio frequency range as the earlier 'b' standard. 802.11g devices are also compatible with 802.11b devices, although they operate at the slower speed in this mode.
802.11n. The most recent ratification of the IEEE wireless standard. This protocol operates within the 2.4GHz or 5GHz spectrum. This protocol can provide up to 130Mbps on a 20MHz operating channel on 2.4GHz and up to 300Mbps on a 40MHz operating channel on 5GHz. Both of these configurations are available at the University.
Wi-Fi. Short for 'Wireless Fidelity'. A branding scheme for 802.11a/b/g equipment from different vendors; equipment from one vendor badged with the 'Wi-Fi' branding should be compatible with other vendors equipment.
WPA2 Enterprise. WPA2 stands for Wi-Fi Protected Access 2. This is a scalable mechanism used for providing authentication from a central resource. A variant of this, WPA2 Personal, is typically used in home or small office setups using a Pre-shared key to protect access.
AES. This is the method by which the data is encrypted on our WPA2 networks. WPA2 implements 128-bit Advanced Encryption Standard (AES) encryption with the use of Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP).
