Fade Margin The difference between strength of the received signal and the strength
that the receiver requires for maintaining a reliable link. A higher fade
margin is characteristic of a more reliable link. Standard operating
margin.
FCC Federal Communications Commission of the U.S.A.
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.
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.
HTTP Hypertext Transfer Protocol, used to make the Internet resources
available on the World Wide Web. Defined in RFC 2068. See
