IEEE 802.11g
802.11g is a proposed (to be finalized) new extension to 802.11b (used in
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.
