Glossary
pmp-0049 (September 2012)
V
Term
Definition
Field-
programmable
Gate Array
Array of logic, relational data, and wiring data that is factory programmed and
can be reprogrammed.
File Transfer
Protocol
Utility that transfers of files through TCP (Transport Control Protocol)
between computing devices that do not operate on the same platform. Defined
in RFC 959. See http://www.faqs.org/rfcs/rfc959.html.
FPGA
Field-programmable Gate Array. An array of logic, relational data, and wiring
data that is factory programmed and can be reprogrammed.
Frame Spreading
Transmission of a beacon in only frames where the receiver expects a beacon
(rather than in every frame). This avoids interference from transmissions that
are not intended for the receiver.
Frame Timing
Pulse Gated Field
Toggle parameter that prevents or allows the module to continue to propagate
GPS sync timing when the module no longer receives the timing.
Free Space Path
Loss
Signal attenuation that is naturally caused by atmospheric conditions and by
the distance between the antenna and the receiver.
Fresnel Zone
Space in which no object should exist that can attenuate, diffract, or reflect a
transmitted signal before the signal reaches the target receiver.
FTP
File Transfer Protocol, defined in RFC 959. Utility that transfers of files
through TCP (Transport Control Protocol) between computing devices that do
not operate on the same platform. See http://www.faqs.org/rfcs/rfc959.html.
Global Positioning
System
Network of satellites that provides absolute time to networks on earth, which
use the time signal to synchronize transmission and reception cycles (to avoid
interference) and to provide reference for troubleshooting activities.
GPS
Global Positioning System. A network of satellites that provides absolute time
to networks on earth, which use the time signal to synchronize transmission and
reception cycles (to avoid interference) and to provide reference for
troubleshooting activities.
GPS/3
Third-from-left LED in the module. In the operating mode for an Access Point
Module, this LED is continuously lit as the module receives sync pulse. In the
operating mode for a Subscriber, this LED flashes on and off to indicate that
the module is not registered.
GUI
Graphical user interface.
High-priority
Channel
Channel that supports low-latency traffic (such as Voice over IP) over low-
latency traffic (such as standard web traffic and file downloads). To recognize
the latency tolerance of traffic, this channel reads the IPv4 Type of Service
DiffServ Control Point (DSCP) bits. Enabling the high-priority channel reduces
the maximum number of SMs that can be served in the sector.
