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.

Rack-optimized

A physical and logical collection of application modules.

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.

Sector Antenna

An antenna type that radiates in only a specific direction. Multiple sector

antennas are commonly used in point-to-multipoint situations.
