802.11g
A supplement to the IEEE 802.11 wireless LAN (WLAN) specification,
describing transmission through the Physical layer (PHY) based on
orthogonal frequency division multiplexing (OFDM), at a frequency of
2.4 GHz and data rates of up to 54 Mbps.

802.11i
A draft supplement to the IEEE 802.11 wireless LAN (WLAN)
specification, for enhanced security through the use of stronger
encryption protocols such as the Temporal Key Integrity Protocol (TKIP)
and AES Counter Mode with Cipher Block Chaining Message
Authentication Code Protocol (AES-CCMP). These protocols provide
replay protection, cryptographically keyed integrity checks, and key
derivation based on the IEEE 802.1X port authentication standard. See
also AES; CCMP; TKIP; WPA.

AAA
Authentication, authorization, and accounting. A framework for
configuring services that provide a secure network connection and a
record of user activity, by identifying who the user is, what the user can
access, and what services and resources the user is consuming. In a
3Com Mobility System, the Wireless Switch (WX) can use a RADIUS
server or its own local database for AAA services.

access point (AP)
A hardware unit that acts as a communication hub by linking wireless
mobile IEEE 802.11 stations such as PCs to a wired backbone network.
A 3Com Mobility System has Managed Access Points (MAPs). See also

ACE
A rule in a security access control list (ACL) that grants or denies a set
of network access rights based on one or more criteria. ACEs use
criteria such as a protocol and a source or destination IP address to
determine whether to permit or deny packets that match the criteria.
ACEs are processed in the order in which they appear in the security
ACL. See also security ACL.
