Decoding LoRa: Realizing a Modern LPWAN with SDR

M.J. Knight, Balint Seeber

Open publisher page 96 citations

Abstract

LoRa is an emerging Low Power Wide Area Network (LPWAN), a type of wireless communication technology suitable for connecting low power embedded devices over long ranges. This paper details the modulation and encoding elements that comprise the LoRa PHY, the structure of which is the result of the author’s recent blind analysis of the protocol. It also introduces grlora, an open source software defined implementation of the PHY that will empower wireless developers and security researchers to investigate this nascent protocol.
