  • Noise floor is the decreasing of the signal amplitude as it travels through free space.
  • Noise floor is the average signal strength of the noise being received by a receiver.
  • Noise floor is the maximum signal strength of the recorded noise received by a receiver.

Noise is any other signal that is received on the same frequency as a signal of interest and noise floor is the average signal strength of that received noise.
