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 pur-

pose of gathering telemetry data. Figure 1-2 on Page 7 shows an

example of an MAS system.

MCU—Microcontroller Unit. This is the processor responsible for con-

trolling 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-revers-

ible,” 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 phys-

ical motion. The movement of the station is not limited to a specific net-

work 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.

PING—Packet INternet Groper. Diagnostic message generally used to

test reachability of a network device, either over a wired or

wireless network.
