- Wireless Signal Mesured in dBm ( Power referenced against one Milliwatt )
- Range is roughly -30dBm to -90dBm
- -30dBm = Max Achievable ( not desired ).
- -67dBm = Mininum for real-time Apps.
- -80dBm = Minimum for communication.
- Noise is always a challenge
- Signal to Noise Ratio ( SNR ) = ( Signal – Noise ) = Value
- Mininum SNR of 25 is needed for real-time apps.
