pose of gathering telemetry data. Figure 1-2 on Page 6 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—A highly secure data encoding scheme. MD5 is a one-way hash

algorithm that takes any length of data and produces a 128 bit “finger-

print”. This fingerprint is “non-reversible”, it is computationally infea-

sible 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 access points as it moves

through the access points' territory. In order to do this, the station

employs roaming and Mobile IP.

Mode—See Device Mode.

MTBF—Mean-Time Between Failures

Multiple Address System (MAS)—See Point-Multipoint System.

Network Address—User-selectable integer that is used to identify a

group of transceivers that form a communications network. The Access

Point and all Remotes within a given system should have the same net-

work address.

Network-Wide Diagnostics—An advanced method of controlling and

interrogating MDS radios in a radio network.

PING—P

acket INternet Groper. Diagnostic message generally used to

test reachability of a network device, either over a wired or wireless net-

work.

Point-Multipoint System—A radio communications network or

system designed with a central control station that exchanges data with

a number of Remote locations equipped with terminal equipment.

Poll—A request for data issued from the host computer (or master PLC)

to a Remote radio.

Portability—Refers to the ability of a transceiver to connect to an

access point from multiple locations without the need to reconfigure the

network settings. For example, a transceiver located in one place and
