164 AWE 120-58 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 AWE
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
The AWE unit uses system image files to store system configuration settings. The default
system image file is called “factory-image” and is used when the AWE 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 AWE unit
can use telnet to access its configuration menus.
