The Regulation of Unlicensed Sub-GHz bands: Are Stronger Restrictions Required for LPWAN-based IoT Success?
share
Radio communications using the unlicensed Sub-GHz bands are expected to play an important role in the deployment of the Internet of Things (IoT). The regulations of the sub-GHz unlicensed bands can affect the deployment of LPWAN networks in a similar way to how they affected the deployment of WLAN networks at the end of the twenty's century. This paper reviews the current regulations and labeling requirements affecting LPWAN-based IoT devices for the most relevant markets worldwide (US, Europe, China, Japan, India, Brazil and Canada) and identify the main roadblocks for massive adaption of the technology. Finally, some suggestions are given to regulators to address the open challenges.
