Abstract
Traditional radio based communication scenarios for both Wireless Personal Area Network (WPAN) and Low Power Wide Area Network (LPWAN) schemes rely heavily on modulation mechanisms over Industrial, Scientific and Medical (ISM) bands. These bands are increasingly getting overcrowded with cordless phone, BLE, Wi‐Fi, IEEE 802.15.4, LoRa and other transmissions. On the other hand, ultrasonic communications can be a valid alternative to some of these radio technologies by providing Near Field Communication (NFC) in the context of WPANs. In this paper we present physical and link layers that rely on a well‐known and proven acoustic modulation mechanism that is adapted and extended to handle the requirements of Internet of Things (IoT) networks over the ultrasonic spectrum. Specifically, the proposed mechanism attempts to comply with one of the most important requirements of IoT, that is, the support of end‐to‐end IPv6 connectivity. This support is critical to enable the integration with IoT devices and applications.
