| Summary: | Long-range (LoRa) is a wireless LPWAN (Low
Power Wide Area Network) communication technology has
been developed for many Internet-of-Things (IoT) applications
in industrial sectors as well as smart city applications. The
performance of LoRa can be affected by environmental factors
that was witnessed in recent research trends. Other geological
factors like terrain types may also have an impact on the link
performance. Hence, this paper highlights the geological factors
that affect LoRa performance in hilly area propagation for
smart city applications. In addition, an experiment was carried
out using 915MHz frequency in the hilly suburban region of
Kuala Lumpur, Malaysia to investigate the performance of
LoRa utilizing different spreading factors (SF7, SF8, SF10,
SF12) and putting the receiver in various altitude scenarios. The
RSSI and packet receive ratio (PRR) were used to determine the
coverage and performance analysis in hilly suburban area. The
outcome of this study shows that the LoRa signal propagation is
affected by the hilly terrain scenarios. Because of the hilly
region, the coverage could be as limited as 1.25Km and the
packet receive ratio was reduced by 65%. Further research is
needed to clarify the detailed propagation scenario between the
transmitter and receiver in hilly areas to propose an optimal
propagation model for a suburban hilly terrain. |
