Abstract

Recently, Low-Power Wide Area Networks (LPWAN) play a key role in the Internet-of-Things (IoT) maturation process. Under the LPWAN broad term are a variety of technologies enabling power efficient wireless communication over very long distances. For instance, technologies based on ultra-narrow band modulation (UNB)–for example SigFox–or Chirp Spread Spectrum modulation (CSS)–for example LoRa–have become de facto standards in the IoT ecosystem. Given the incredible ...
