IEEE
The Institute of Electrical & Electronics Engineers, Inc. (IEEE) is an organization that
develops standards for electrical and electronic equipment. IEEE 802.xx standards define the
access technologies for local and metropolitan area networks.
IEEE 802.11
IEEE 802.11 compliant networking products based on the same type of distribution system
are interoperable with one another regardless of the device’s manufacturer. 802.11 provides
1 or 2 Mbps transmission in the 2.4GHz band. 802.11b defines an 11 Mbps data rate in the
2.4GHz band. 802.11a defines 24 Mbps in the 5GHz band.
IEEE 802.1X
IEEE 802.1X uses security protocols, such as RADIUS, to provide centralized user
identification, authentication and dynamic key management.
ISA
Industry Standard Architecture. An expansion bus commonly used in PCs. It accepts the
plug-in boards that control the video display, disks and other peripherals, including wireless
radio cards (via an ISA carrier). Most PCs today use the ISA and PCI buses and have a
combination of ISA and PCI slots. See PCI.
ISA adapter
An option for the RoamAbout PC Card for computers that do not have a PCMCIA slot. The
ISA adapter installs into a computer’s ISA bus and provides a PCMCIA slot for the PC Card.
MAC address
This is the hardware address of the device. The MAC address consists of 12 hexadecimal
digits, and is printed on the device.
multicast message
A data message that is transmitted by a wired or wireless device to multiple devices within a
network. Unlike broadcast messages, multicast messages do not always include all devices
in the network.
multipoint bridge mode
An AP mode that allows up to seven APs to communicate, effectively connecting wired
LANs through a wireless link.
