majority of wireless LANs today) that broadens 802.11b’s data rates to 54

Mbps within the 2.4 GHz band using OFDM (orthogonal frequency division

multiplexing) technology. 802.11g allows backward compatibility with

802.11b devices but only at 11 Mbps or lower, depending on the range and

presence of obstructions.

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.

ISP (Internet Service Provider)
An organization that provides access to the Internet. Small ISPs provide

service via modem and ISDN while the larger ones also offer private line

hookups (T1, fractional T1, etc.).

LAN (Local Area Network)
A communications network that serves users within a defined geographical

area. The benefits include the sharing of Internet access, files and equipment

like printers and storage devices. Special network cabling (10 Base-T) is

often used to connect the PCs together.
