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 TS
Wireless 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.
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 AP from multiple locations
without the need to reconfigure the network settings. For example, a transceiver located in
one place and connected to an AP can be turned off, moved to another place, turned back on;
and, when the right information is entered, can immediately reconnect to the AP without
intervention.
PLC—Programmable Logic Controller. A dedicated microprocessor configured for a specific
application with discrete inputs and outputs. It can serve as a host or as an endpoint device.
Remote—A transceiver in a network that communicates with an associated AP radio.
