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. 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. 

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. 

SSID

 

A Network ID unique to a network. Only clients and Access Points that 

share the same SSID are able to communicate with each other. This string 

is case-sensitive. 

Static IP Addressing

 

A method of assigning IP addresses to clients on the network. In networks 

with Static IP address, the network administrator manually assigns an IP 

address to each computer. Once a Static IP address is assigned, a computer
