Noise <-- --> Interference: The difference ?

Hi,

The Lwapp controller reports a noise/channel chart and an interference/channel chart.

In the wirelles RF world, What's the difference between noises and interferences ?

regards

Cedric

The short answer is that "Interference" is in-band (same / close frequencies and possibly signaling), "Noise" is out-of-band: Things like electromagnetic interference (EMI) or radio-frequency interference(RFI) along with other forms of impulse-generated events (sparky motors, lightning, static discharges, flourescent baluns, arc sources, etc).

FWIW

Thermal noise is inband.

-94dBm/100MHz.

If noise and interference is unwanted energy in the receiver band then its sources may make the difference.

Interference would be from the use of co and adjacent channels for the same type of service.

Noise would be from other sources, permanent or accidental.

Just speculating.
