164 AWE 120-24 Installation & Configuration Guide
RS-232
Standards for serial communications, which define the voltages, currents, data rates and
other factors about the signals to be used, as well as single-ended, differential, multi-drop
operation.
RSSI
Received Signal Strength Indicator. Strength of received signal expressed in dB. The unit
measures RSSI as a fade margin value.
S
scrambling code
A code used to scramble messages, so that only units with the same scrambling can read
the messages.
sensitivity
The minimum signal strength required for usable performance by a unit. Expressed in
dBm.
shadowing
Shadowing is a form of diffraction that is typically caused when antennas are mounted
too close to a structure and lose a portion of the signal lobe due to reflection. The
receive antenna is in a shadowed area. To minimize shadowing, ensure that there is
adequate height above when mounting antenna equipment to a structure.
SNMP
Simple Network Management Protocol. A protocol you can use to remotely manage a
network element by polling, setting terminal values, and monitoring network statistics
and events. It is the de facto internet work management standard, designed to provide a
mechanism for the exchange of management information in a TCP/IP-based Internet
environment.
spread spectrum (SS)
Any of a group of modulation formats in which an RF bandwidth much wider than signal
bandwidth is used to transmit information, resulting in a greater immunity to noise
interference.
system gain
The maximum path loss that the system can support for usable data transmission.
system image file
A unit uses system image files to store system configuration settings. The default system
image file is called “factory-image” and is used when the unit is first powered up.
T
telnet
An Internet communications protocol that enables a computer to function as a terminal
working on a remote computer. A computer with a network connection to a unit can use
telnet to access its configuration menus.
