which may cause errors. Inter-packet delay resolves this through the use
of buffers.
kbps —kilobits per second. See bps .
LAN— Local Area Network
Latency —The delay (usually expressed in milliseconds) between when
data is applied at the transmit port at one radio, until it appears at the
receive port at the other radio.
MAS —Multiple Address System. A radio system where a central
master station communicates with several remote stations for the
purpose of gathering telemetry data.
Figure 1-2 on Page 7 shows an
example of a MAS system.
MCU —Microcontroller Unit. This is the processor responsible for
controlling system start-up, synthesizer loading, hop timing, and key-up
control.
MD5 —Message-Digest algorithm 5. A highly secure data encoding
scheme. MD5 is a one-way hash algorithm that takes any length of data
and produces a 128 bit “fingerprint”. This fingerprint is
“non-reversible,” it is computationally infeasible to determine the file
based on the fingerprint. For more details check out “RFC 1321” on the
Internet.
Microcontroller Unit —See MCU .
Mobility —Refers to a station that moves about while maintaining
active connections with the network. Mobility generally implies
physical motion. The movement of the station is not limited to a specific
network and IP subnet. In order for a station to be mobile it must
establish and tear down connections with various APs as it moves
through the APs' territory. In order to do this, the station employs
roaming and Mobile IP.
MTBF —Mean Time Between Failures
Multiple Address System (MAS) —See Point-Multipoint System.
Network Address —User-definable integer that is used to identify a
group of transceivers that form a communications network. The AP and
all Remotes within a given system
should have the same network
address.
Network-Wide Diagnostics —An advanced method of controlling and
interrogating GE MDS radios in a radio network.
PHY— Physical layer of the Ethernet LAN.
