Protocol
The language or packaging of information that is transmitted between nodes on a
network.
Q
QoS
Quality of Service. Required to support wireless multimedia applications and
advanced traffic management. QoS enables Wi-Fi access points to prioritize
traffic and optimize the way shared network resources are allocated among
different applications.
R
RADIUS
Remote Access Dial-In Service. This describes a general method for allowing
remote users access to a network. It authenticates the user, specifies passwords
and access rights to network resources. It also keeps track of accounting for
when and how long the user is logged onto the network. It was originally used for
dial-in users, accessing corporate networks via modems. It is now being
specified as part of the 802.11i standard to control access of users to wireless
networks. Any of several protocols can be used by the wireless client to
communicate with the RADIUS server to gain access to the network resources.
These protocols include EAP-TLS (Windows), LEAP (Cisco) and EAP-TTLS.
Range
The distance covered by a wireless network radio device. Depending on the
environment and the type of antenna used, Wi-Fi signals can have a range of up
to a mile.
Remote Access Point
One of a number of secondary access points in a wireless network that uses
WDS to extend its range. Remote access points (sometimes called relay access
points) connect to a master access point.
Remote device
Devices connected remote radios
Repeater
A Repeater is a device used to extend the range of a Wi-Fi signal. Placed at the
edge of signal reception, a repeater simply receives and re-transmits the signal.
RS-232
Recommended Standard 232; the standard for serial binary signals between
DTE and DCE devices.
