IEEE 802.11
The IEEE 802.xx is a set of specifications for LANs from the Institute of Electrical and
Electronic Engineers (IEEE). Most wired networks conform to 802.3, the specification
for CSMA/CD-based Ethernet networks or 802.5, the specification for token ring
networks. IEEE 802.11 defines the standard for wireless LANs encompassing three
incompatible (non-interoperable) technologies: Frequency Hopping Spread Spectrum
(FHSS), Direct Sequence Spread Spectrum (DSSS), and Infrared. IEEE standards
ensure interoperability between systems of the same type.
IEEE 802.1X
The "Port Based Network Access Control" requires that a device that accesses a
network is first authenticated. The initial connecting point of the network is the
"authenticator." It relays the accessing device's credential to a backend
"authentication server." The process that presents the request is referred to as the
"Supplicant." Only when the authentication server so determines, the network access
device will open its port for the requesting device. The authentication server is
generally a RADIUS. In order for the request to be granted, the RADIUS must be
properly configured to recognize the requester's credential.
Infrastructure Network
A wireless network centered about an Access Point. In this environment, the Access
Point not only provides communication with the wired network but also mediates
wireless network traffic in the immediate neighborhood.
IP
Internet Protocol is the standard protocol within that defines the basic unit of
information passed across an Internet connection by breaking down data messages
into packets, routing and transporting the packets over network connections, then
