Samenvatting

Wireless sensor networks are getting more and more attention because of the spreading
acknowledgement of the Internet of Things for industrial solutions and households. It is estimated that
over 50 billion devices will be connected to Internet by year 2020. Most of these devices will be part of IoT
and/or M2M systems. Wireless sensor networks (WSNs) are attracting growing attention for their
availability and low cost. Until recently their range was limited to a few hundred meters in line-of-sight
situations. In 2013 LoRa technology was introduced, which surpassed those few hundred meters and
transmitted signal over 15 km range, while being low-power. This article describes possible PHY and MAC
layer implementation of LoRa technology for a typical real-life WSN by comparing supporting
microcontrollers and evaluating existing MAC layers for WSNs. It can be concluded that LoRa technology is
suited for any microcontroller with SPI peripheral and is arguably the most befitting solution for a lowpower
long-range WSN solutions.
