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
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.
Repeater, Radio Mode
A RLX2 radio in Repeater mode can only connect to other ProSoft radios, but
any number of Ethernet network devices can be attached to it. See also Client,
Radio Mode.
RS-232
Recommended Standard 232; the standard for serial binary signals between
DTE and DCE devices.
RTU (Remote Terminal Unit)
Modbus transmission mode where each eight-bit byte in a message contains two
four-bit hexadecimal characters. There are two transmission modes (ASCII or
RTU). The main advantage of the RTU mode is that its greater character density
allows better data throughput than ASCII mode for the same baud rate; each
message is transmitted in a continuous stream (See also ASCII, above).
