BreezeMAX Si 4000 CPE 116 User Manual
Received signal strength
indication (RSSI) A measurement of the power present in a received radio signal.
RSSI is generic radio receiver technology metric, which is
usually invisible to the user of device containing the receiver,
but is directly known to users of wireless networking of

IEEE 802.11 protocol family.
Real-time Transport
Protocol (RTP) The Real-time Transport Protocol (RTP) defines a standardized
packet format for delivering audio and video over the Internet.
Real-time Transport
Control Protocol (RTCP) Real-time Transport Control Protocol (RTCP) is a sister protocol
of the Real-time Transport Protocol (RTP).
RTCP provides out-of-band control information for an RTP
flow. It partners RTP in the delivery and packaging of
multimedia data, but does not transport any data itself. It is
used periodically to transmit control packets to participants in
a streaming multimedia session. The primary function of RTCP
is to provide feedback on the quality of service being provided
by RTP.
RTS Threshold Transmitters contending for the medium may not be aware of
each other. RTS/CTS mechanism can solve this “Hidden Node
Problem”. If the packet size is smaller than the preset RTS
Threshold size, the RTS/CTS mechanism will NOT be enabled.
Service Set Identifier
(SSID) An identifier that is attached to packets sent over the wireless
LAN and functions as a password for joining a particular radio
cell; i.e., Basic Service Set (BSS).
Session Key Session keys are unique to each client, and are used to
authenticate a client connection, and correlate traffic passing
between a specific client and the AU-EZ.
Shared Key A shared key can be used to authenticate each client attached
to a wireless network. Shared Key authentication must be used
along with the 802.11 Wireless Equivalent Privacy algorithm.
Session Initiation
Protocol (SIP) An application-layer control (signaling) protocol for creating,
modifying, and terminating sessions with one or more
participants. It can be used to create two-party, multiparty, or
multicast sessions that include Internet telephone calls,
multimedia distribution, and multimedia conferences.
Simple Network
Management Protocol
(SNMP) Simple Network Management Protocol: The application
protocol in the Internet suite of protocols which offers network
management services.
