Gateway
A gateway is a hardware and soft ware 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.
Infrastructure is applicable to enterprise scale for wireless access to central database,
or wireless application for mobile workers.
ISM B and
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
p resents 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 tha t 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 PC Card.
Protocol
A protoco l is a standardized set of rules that specify how a conversation 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 co nnected access point and connects to a newly connected access point.
Throughout the network environment where access point are deployed, PCs can
always be connected regardless of where they are located or roam.
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.
Simple Network Management Protocol (SNMP)
Simple Network Management Protocol is the network management protocol of TCP/IP.
In SNMP, agents-which can be hardware as well as software -monitor the activity in the
various devices on the network and report to the network console workstation. Control
information about each device is maintained in a structure known as a management
information block.
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 uses the same IP address
every time it reboots and logs on to the network, unless it is manually changed.
Transmission Control Protocol / Internet Protocol (TCP/IP)
TCP/IP is the protocol suite developed by the Advanced Research Projects Agency
(ARPA). It is widely used in corporate Internet works, because of its superior design for
WANs. TCP governs how packet is sequenced for transmission the network. The term
“TCP/IP” is often used generically to refer to the entire suite of related protocols.
Transmit / R eceive
The wireless throughput in Bytes per second averaged over two seconds.
Wide Area Network (WAN)
A WAN consists of multiple LANs that are tied together via telephone services and / or
fiber optic cabling. WANs may span a city, a state, a country, or even the world.
