LoRa — LoRa documentation

If SNR is greater than 0, the received signal operates above the noise floor. If SNR is smaller than 0, the received signal operates below the noise floor. Normally the noise floor is the physical limit of sensitivity, however LoRa works below the noise level. Typical LoRa SNR values are between: -20dB and +10dB.

Basic properties of a quarterwave monopole antenna

The described antenna should be fabricated on standard 1.6mm, low cost FR4 printed circuit board (PCB). 2. Basic properties of a quarterwave monopole antenna A quarterwave monopole is a ground plane dependent antenna that must be fed single-ended. The antenna must have a ground plane to be efficient, and ideally the ground plane should
