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.

.
FPGA Field-programmable Gate Array. An array of logic, relational data, and wiring data
that is factory programmed and can be reprogrammed.
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.
HTTP Hypertext Transfer Protocol, used to make the Internet resources available on the
World Wide Web. Defined in RFC 2068. See http://www.faqs.org/rfcs/rfc2068.html
