Chapter 6 - Glossary
ESSID (Extended Service Set Identifier)
You must have the same ESSID entered into the gateway and each of its wireless
clients. The ESSID is a unique identifier for your wireless network.
Ethernet
The most widely used LAN access method, which is defined by the IEEE 802.3 standard.
Ethernet is normally a shared media LAN meaning all devices on the network segment
share total bandwidth. Ethernet networks operate at 10Mbps using CSMA/CD to run
over 10Base-T cables.
Gateway
A network point that manages all the data traffic of your network, as well as to the
Internet and connects one network to another.
IEEE
The Institute of Electrical and Electronics Engineers. The IEEE sets standards for
networking, including Ethernet LANs. IEEE standards ensure interoperability between
systems of the same type.
IEEE 802.11
IEEE 802.xx is a set of specifications for LANs from the Institute of Electrical and
Electronic Engineers (IEEE). Most wired networks conform to 802.3, the specification
for CSMA/CD based Ethernet networks or 802.5, the specification for token ring
networks. 802.11 defines the standard for wireless LANs encompassing three
incompatible (non-interoperable) technologies: Frequency Hopping Spread Spectrum
(FHSS), Direct Sequence Spread Spectrum (DSSS), and Infrared. 802.11 specifies a
carrier sense media access control and physical layer specifications for 1 and 2 Mbps
wireless LANs.
IEEE 802.11a / IEEE 802.11b
See next few pages for detailed explanations.
Infrastructure
A wireless network centered about an access point. In this environment, the access
point not only provides communication with the wired network but also mediates
wireless network traffic in the immediate neighborhood.
IP (Internet Protocol)
The TCP/IP standard protocol that defines the IP datagram as the unit of information
passed across an Internet and provides the basis for connectionless packet delivery
service. IP includes the ICMP control and error message protocol as an integral part. It
provides the functional equivalent of ISO OSI Network Services.
IP Address
An IP address is a 32-bit number that identifies each sender or receiver of information
that is sent across the Internet. An IP address has two parts: the identifier of a particular
network on the Internet and an identifier of the particular device (which can be a server
or a workstation) within that network.
ISM Bands (Industrial, Scientific, and Medicine Bands)
Radio frequency bands that the Federal Communications Commission (FCC) authorized
for wireless LANs. The ISM bands are located at 902 MHz, 2.400 GHz, and 5.7 GHz.
