Shadowing Impact on LoRa LPWAN Radio Links
LoRaWAN is expected to be one of the key elements of the Internet of Things using long range, low power wireless telecommunications. LoRaWAN enables end appliances to communicate within a single hop through a gateway to the Internet. These gateways serve to unify two end devices with a central network server which is the transparent pathway of messages from the end devices. This technology, which combines long range, low battery consumption and secure data transmission is proving to be very popular in Internet of Things networks that wireless network carriers are introducing. However, the public inventory of the technology is not as through an assessment. The main purpose of this paper is to study the influence of shadowing over LoRaWAN networks and determine the performance in terms of packet loss ratio for different physical layer configurations. This shows that the intended performance has significant performance variances that are sufficiently disruptive when shadowing is taken into consideration.
