IEEE 802.15.4w-2020

IEEE Standard for Low-Rate Wireless Networks--Amendment 2: Low Power Wide Area Network (LPWAN) Extension to the Low-Energy Critical Infrastructure Monitoring (LECIM) Physical Layer (PHY)

The existing low-energy critical infrastructure monitoring (LECIM) frequency shift keying (FSK) physical layer of IEEE Std 802.15.4-2020 is extended to be more robust in the presence of interference and achieve higher link budgets for applications in low power wide area networks (LPWAN). Lower symbol rates and a split mode with low-rate forward error correction (FEC) codes are introduced to achieve this goal.
