Comparison of wireless techniques applied to environmental sensor monitoring

Abstract

This report investigates the technological basis for low power, low bitrate, medium range, wireless transmission of environmental sensor data. This is a typical 'Internet of Things' (IoT) application, and most of our findings are therefore generally applicable to the wider IoT field. The report starts with an overview of the relevant regulatory framework, in particular the differences between Europe and the USA. It then discusses the various key performance indicators of the wireless IoT communication channel and presents an overview of some of the wireless standards available today. While performances are often discussed, ecosystems appear as important for the sustainability of different systems. Future work includes a more in-depth analysis of selected standards in order to assess the scalability potential. Oppdragsgiver: Norges Forskningsråd
