IGateway
A gateway is a hardware and software device that connects two dissimilar systems,
such as a LAN and a mainframe. In Internet terminology, a gateway is another name
for a router. Generally a gateway is used as a funnel for all traffic to the Internet.

Infrastructure
An integrated wireless and wired LAN is called an Infrastructure configuration. Infra-
structure is applicable to enterprise scale for wireless access to a central database,
or wireless applications for mobile workers.
ISM Band
The FCC and their counterparts outside the U.S. have set aside bandwidth for un-
licensed 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 tel-
ephone 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.
Protocol
A protocol is a standardized set of rules that specify how communication is to take
place, including the format, timing, sequencing and/ or error checking.
Roaming
In an infrastructure network, this is when a wireless PC moves out of range of the
previously connected access point and connects to a newly connected access point.
Throughout the network environment where access points are deployed, PCs can
always be connected, regardless of where they are located.
