group. A subset of
802.11e
features is described in the
WMM
specification.
R
RADIUS
The
Remote Authentication Dial-In User Service
(RADIUS) provides an authentication and accounting
system. It is a popular authentication mechanism for many
ISP
s.
RC4
A symmetric stream cipher provided by
RSA Security
. It is a variable key-size stream cipher with byte-
oriented operations. It allows keys up to 2048 bits in length.
Roaming
In
IEEE
802.11
parlance,
roaming clients
are mobile client stations or devices on a wireless network
(
WLAN
) that require use of more than one
a
as they move out of and into range of different base station
service areas. IEEE
802.11f
defines a standard by which APs can communicate information about client
associations and disassociations in support of roaming clients.
Router
A
router
is a network device which forwards packets between networks. It is connected to at least two
networks, commonly between two local area networks (
LAN
s) or between a
LAN
and a wide-area network
(
WAN
), for example, the Internet. Routers are located at gateways—places where two or more networks
connect.
A router uses the content of headers and its tables to determine the best path for forwarding a packet. It
uses protocols such as the Internet Control Message Protocol (ICMP), Routing Information Protocol (RIP),
and Internet Router Discovery Protocol (IRDP) to communicate with other routers to configure the best
route between any two hosts. The router performs little filtering of data it passes.
RSSI
The
Received Signal Strength Indication
(RSSI) an
802.1x
value that calculates voltage relative to the
received signal strength. RSSI is one of several ways of measuring and indicating
radio frequency
(RF)
signal strength. Signal strength can also be measured in mW (milliwatts), dBms (decibel milliwatts), and a
percentage value.
RTP
Real-Time Transport Protocol
(RTP) is an Internet protocol for transmitting real-time data like audio and
video. It does not guarantee delivery but provides support mechanisms for the sending and receiving
applications to enable streaming data. RTP typically runs on top of the
UDP
protocol, but can support other
transport protocols as well.
RTS
A
request to send
(RTS) message is a signal sent by a client station to the access point, asking permission
to send a data packet and to prevent other wireless client stations from grabbing the radio waves. This
message is a part of the IEEE 802.11
CSMA/CA
protocol. (See also
RTS Threshold
and
CTS
.)
