ZigBee and LoRa performances on RF Propagation on the Snow Hills area

In the research, the analysis of LoRa 915, 920 MHz, and ZigBee 2.4 GHz data transmission in an outdoor area with snow conditions and the transmitter and receiver position in the mountains full of Snow. Delivery conditions are sometimes hindered by heavy Snow; for this reason, in this research, ZigBee and LoRa Quality of Service calculations were carried out in severe snow conditions. They use the measurement method approach, i.e., two ray Ground reflection model, using the Free Space Path Loss (FSPL) approach between 2 Radio Frequency (RF) LoRa and ZigBee. A significant comparison is obtained from LoRa and ZigBee propagation regarding sending Tx to Rx data. The comparison between ZigBee and LoRa in this research is that the Transmitter (T
x
) position is on a hill and the Receiver (R
x
) is on a flat plane, with Transmitter Height (h
t
) and Receiver Height (h
r
) parameters, so that this allows signal reflection to occur. The difference between the standard ground layer and the snow-covered surface is also calculated in Attenuation during data transmission.
