Abstract:
Temperature variations are known to affect the performance of wireless sensor networks deployed outdoors.
Whilst the impact of temperature on IEEE 802.15.4 transceivers has long been investigated by the research
community, still little is known about how temperature affects the performance of increasingly popular long-range
wireless technologies such as LoRa. To fill this gap, this paper presents an experimental evaluation
of the reliability of LoRa in the presence of temperature variations. First, we highlight that temperature can
have a significant impact on LoRa’s communication performance and show that an increase in temperature
can be sufficient to transform a perfect LoRa link into an almost useless one. We then carry out a detailed
investigation on the performance of different LoRa physical settings with fluctuating temperatures and show
that an optimal selection can help in increasing the probability of packet reception and is hence key to mitigate
temperature-induce
d effects. We believe that our results will serve as a reference to orient researchers and
system designers employing LoRa to build large-scale low-power wide area networks.
