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.
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 network environment where access point is deployed,
PCs can always be connected regardless of where they are located or roam.
SSID
A Network ID require 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-this 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.
