Users Guide

G
GHz gigahertz A unit of frequency equal to 1 000 000 000 cycles per second.
GINA Graphical Identification and Authentication A dynamic link library (DLL) file
that is part of the Windows operating system. GINA is loaded early in the boot
process and handles the user identification and authorization logon process.
GTC Generic Token Card A type of tunneled authentication protocol used in
conjunction with
PEAP authentication in which the user types the data displayed by
a token card device when logging on to the wireless network.
H
host computer The computer that is directly connected to the Internet via a modem or network
adapter.
I
IEEE Institute of Electrical and Electronics Engineers, Inc.
IEEE 802.1X-2001 The IEEE standard for Port Based Network Access Control. The IEEE 802.1X
standard enforces authentication of a network node before it can begin to
exchange data with the network.
IEEE 802.11a The 54 Mbps, 5 GHz standard (1999)
IEEE 802.11b The 11 Mbps, 2.4 GHz standard.
IEEE 802.11d International (country-to-country) roaming extensions.
IEEE 802.11e IEEE 802.11e (as of July 2005) is a draft standard that defines a set of
Quality of
Service enhancements for LAN applications, in particular the IEEE 802.11 Wi-Fi
®
standard. The standard is considered of critical importance for delay-sensitive
applications, such as Voice over Wireless IP and Streaming Multimedia.
IEEE 802.11g The 54 Mbps, 2.4 GHz standard (backwards compatible with IEEE 802.11b) (2003)
IEEE 802.11h A supplementary standard to IEEE 802.11 to comply with European regulations. It
adds transmission power control and dynamic frequency selection.
IEEE 802.11i IEEE 802.11i (also known as
WPA2™) is an amendment to the IEEE 802.11
standard specifying security mechanisms for wireless networks. The draft standard
was ratified on 24 June 2004, and supersedes the previous security specification,
Wired Equivalent Privacy (
WEP), which was shown to have severe security
weaknesses.
IEEE 802.11n IEEE 802.11n is a amendment to the IEEE 802.11 standard. The IEEE 802.11n
draft standard specifies the use of multiple receivers and transmitters to achieve
increased throughput over wireless networks that is significantly greater than is
currently possible.
IETF Internet Engineering Task Force A large open international community of
network designers, operators, vendors, and researchers concerned with the
evolution of the Internet architecture and the smooth operation of the Internet.
infrastructure network A network in which there is at least one
wireless router/AP and one wireless client.
The wireless client uses the wireless router/AP to access the resources of a
traditional wired network. The wired network can be an organization intranet or the
Internet, depending on the placement of the wireless router/AP.
intermediate certificate A certificate issued by an intermediate certification authority (CA). See also
root
certificate.
Internet Protocol (IP) address The address of a computer that is attached to a network. Part of the address
designates which network the computer is on, and the other part represents the
host identification.
IPv6 Internet Protocol Version 6 IPv6 is the next generation protocol designed by the
IETF to replace the current version Internet Protocol, IP Version 4 (IPv4).
ISM frequency bands Industrial, Scientific, and Medical frequency bands in the range of 902–928 MHz,
2.4–2.485 GHz, 5.15–5.35 GHz, and 5.75–5.825 GHz.
ITU-T X.509 In cryptography, ITU-T X.509 is an International Telecommunication Union
Telecommunication Standardization Sector (ITU-T) standard for public key
infrastructure (
PKI). Among other things, ITU-T X.509 specifies standard formats
for public key
certificates and a certification path validation algorithm.
