This work studies the coverage of the recently developed LoRa LPWAN technology via real-life measurements and presents a channel attenuation model derived from the measurement data that can be used to estimate the path loss in 868 MHz ISM band in an area similar to Oulu, Finland.Abstract:
In addition to long battery life and low cost, coverage is one of the most critical performance metrics for the low power wide area networks (LPWAN). In this work we study the coverage of the recently developed LoRa LPWAN technology via real-life measurements. The experiments were conducted in the city of Oulu, Finland, using the commercially available equipment. The measurements were executed for cases when a node located on ground (attached on the roof rack of a car) or on water (attached to the radio mast of a boat) reporting their data to a base station. For a node operating in the 868 MHz ISM band using 14 dBm transmit power and the maximum spreading factor, we have observed the maximum communication range of over 15 km on ground and close to 30 km on water. Besides the actual measurements, in the paper we also present a channel attenuation model derived from the measurement data. The model can be used to estimate the path loss in 868 MHz ISM band in an area similar to Oulu, Finland.read more

Do LoRa Low-Power Wide-Area Networks Scale?
TL;DR: This paper develops models describing LoRa communication behaviour and uses these models to parameterise a LoRa simulation to study scalability, showing that a typical smart city deployment can support 120 nodes per 3.8 ha, which is not sufficient for future IoT deployments.

Low Power Wide Area Network Analysis: Can LoRa Scale?
Orestis Georgiou,Usman Raza +1 more
TL;DR: In this paper, the authors provide a stochastic geometry framework for modeling the performance of a single gateway LoRa network, a leading LPWA technology, and show that the coverage probability drops exponentially as the number of end-devices grows due to interfering signals using the same spreading sequence.
