and tear down connections with various access points as it moves
through the access points' territory.
Mode—See Device Mode.
MTBF—Mean-Time Between Failures
Multiple Address System (MAS)—See Point-Multipoint System.
NMEA—National Marine Electronics Association. National body that
established a protocol for interfacing GPS data between electronic
equipment.
Network Name—User-selectable alphanumeric string that is used to
identify a group of radio units that form a communications network. The
Access Point 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.
NTP—Network Time Protocol
Packet—The basic unit of data carried on a link layer. On an IP network,
this refers to an entire IP datagram or a fragment thereof.
PING—Packet INternet Groper. Diagnostic message generally used to
test reachability of a network device, either over a wired or wireless net-
work.
PKI—Private Key Infrastructure. A set of policies and technologies
needed to create, store, and distribute Public Key Certificates used to
protect the security of network communications.
Point-to-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 device.
Portability—A station is considered connected when it has successfully
authenticated and associated with an access point. A station is consid-
ered authenticated when it has agreed with the access point on the type
of encryption that will be used for data packets traveling between them.
The process of association causes a station to be bound to an access
point and allows it to receive and transmit packets to and from the access
point. In order for a station to be associated it must first authenticate
with the access point. The authentication and association processes
occur automatically without user intervention.
