Infrastructure

An integrated wireless and wired LAN is called an Infrastructure configuration.

Infrastructure is applicable to enterprise scale for wireless access to central database,

or wireless application for mobile workers.

ISM Band

The FCC and their counterparts outside of the U.S. have set aside bandwidth for

unlicensed use in the so-called ISM (Industrial, Scientific and Medical) band.

Spectrum in the vicinity of 2.4 GHz, in particular, is being made available worldwide.

This presents a truly revolutionary opportunity to place convenient high-speed

wireless capabilities in the hands of users around the globe.

Local Area Network (LAN)

A LAN is a group of computers, each equipped with the appropriate network adapter

card connected by cable/air, that share applications, data, and peripherals. All

connections are made via cable or wireless media, but a LAN does not use telephone

services. It typically spans a single building or campus.

Network

A network is a system of computers that is connected. Data, files, and messages can

be transmitted over this network. Networks may be local or wide area networks.

PCMCIA

Personal Computer Memory Card International Association. Also a PCMCIA card is

also referred to Cardbus Adapter.

Protocol

A protocol is a standardized set of rules that specify how a conversation is to take

place, including the format, timing, sequencing and/ or error checking.
