Reviewer 2 Report
This paper characterizes the performance of LoRa specifically in the unlicensed ISM bands in 920 MHz range in a particular propagation environment, namely a hilly forested area. The results in the paper are insightful and the work assists in building the body of literature in performance evaluation of LoRa.
The following are some comments on how the paper could be further improved.
-- Can the authors comment on the scalability of the results? How scalable are these results to other similar or related environments?
-- Along the lines of the previous comments, can the authors model the transmission and performance of LoRa in the given setting so that following this work, analysis of LoRa can use the developed model(s)?
-- It is recommended that the authors also provide a theoretical framework for their work that can justify and provide intuitive basis for their results. For example, the authors can use standard channel models, e.g. 3GPP channel models, to approximate the practical propagation environment. They could use e.g. the TDL or CDL models that do not rely on standard communication environments. This can also improve the scalability of the work.
On the editorial side, there are some typos that the authors need to correct. In general, the English language needs to be substantially enhanced.
