Description

The Internet of Things market has emerged over the past decades and maintains to grow. Therefore, IoT devices have become omnipresent. Many of these devices use a wireless connection to send and receive data. Many of these wireless connections are based upon Low Power Wide Area Network protocols such as NB-IoT, LoRa or Sigfox. Due to the increasing amount of IoT devices, these LPWAN protocols will become even more important. However, many of these protocols are proprietary and therefore it remains unknown how they exactly operate. We dive into the inner workings of one of these LPWAN protocols. More specifically, we investigate the PHY of the DASH7 Alliance Protocol (D7AP). We present a fully-fledged DASH7 communication system using GNU Radio. The software can be used as a simulation instrument and can be applied in real-life scenarios by using low-cost Software-Defined Radios. In this way, it is possible to investigate a complete IoT transceiver system that is open-source and easily adaptable. Furthermore, it can be used to build up, investigate and validate DASH7 data packets.
