← ScienceWhich mechanism causes signal fading in LoRaWAN networks?
A)Constructive wave interference mitigation
B)Multipath wave propagation✓
C)Increased signal transmit power
D)Reduced spreading factor
💡 Explanation
Multipath wave propagation causes signal fading because reflections interfere creating distortions impacting signal reliability leading to fading. Power increase is irrelevant therefore multipath causes interference, rather than fixing it preventing errors.
