FFT
Fast Fourier Transform. FFT is a frequency analysis mechanism that aims at faster conversion of a discrete
signal in time domain into a discrete frequency domain representation. See also DFT.
FHSS
Frequency Hopping Spread Spectrum. FHSS is transmission technique that allows modulation and
transmission of a data signal by rapidly switching a carrier among many frequency channels in a random but
predictable sequence. See also DSSS.
FIB

Internet.
FQLN
Fully Qualified Location Name. FQLN is a device location identifier in the format:
APname.Floor.Building.Campus.
frequency allocation
Use of radio frequency spectrum as regulated by governments.
FSPL
Free Space Path Loss. FSPL refers to the loss in signal strength of an electromagnetic wave that would result
from a line-of-sight path through free space (usually air), with no obstacles nearby to cause reflection or
diffraction.
