Particle Electron: Understanding RSSI→qual (I want to understand levels of rf interference the particle is picking up)

I am placing a Particle Electron near some noisy power electronics. I want a metric that I use to work out how much the power electronics are messing up things with the particle.

This ‘qual’ value looks interesting
“is a number in UMTS RAT indicating the Energy per Chip/Noise ratio in dB levels of the current cell”

  • don’t really understand this, any links to definition?
  • Is it somewhat a signal-to-noise value?

  • qual : ( int ) is a number in UMTS RAT indicating the Energy per Chip/Noise ratio in dB levels of the current cell. This value ranges from 0 to 49, higher numbers indicate higher signal quality.
