Received Signal Strength Indicator (RSSI)
The RSSI Voltage provided at the output of the RF Unit that is used to indicate the RF Input Level.
Reflection
The sharp change in direction of a wave after hitting an obstruction in its path.
Refraction
The bending of a wave as it moves from one medium to another.
Reliability
A measure of the percentage of time the system is operating. Reliability is usually a measure of both the availability of the
signal and the MTBF of the equipment.
Responsible personnel
This is the person(s) responsible for maintaining the radio system.
RF Signal Level
The strength of the power received by the RF Unit from the antenna.
Right arrow
This is the right arrow key on your keyboard.
Router
This device filters out network traffic by specific protocol rather than by packet address. This device operates at the
Network layer of the OSI model. Routers also divide networks logically instead of physically. An IP router can divide a
network into various subnets so that only traffic designated for particular IP addresses can pass between segments.
Network speed often decreases due to this type of intelligent forwarding. Such filtering takes more time than exercised in a
switch or bridge, which only looks at the Ethernet address. In more complex networks, overall efficiency is improved by
using routers.
Rx (Receiver)
This is where the packet is going.
Server
A computer that is responsible for tracking, as well as receiving and sending requests from other computers connected to
it (on the same network).
