Need PHY for Regions No Sub-GHz band suitable on a global basis January 2016 Need PHY for Regions No Sub-GHz band suitable on a global basis Different Sub-GHz frequency bands used in different countries have different rules New spectrum is available and have been opened up after 15.4g amendment for Smart Utility Networks and Smart Cities, for example: 870-876 MHz (European band) 919-923 MHz (Malaysia) Kunal Shah (SSN)

Proposal Specify operational PHY parameters for existing 15.4 regions January 2016 Proposal Specify operational PHY parameters for existing 15.4 regions Define PHY parameters for additional Sub-GHz bands Kunal Shah (SSN)
