Unlike Wi-Fi or Zigbee, there is no industry-wide accepted technology for long-range, ultra-low power systems. To meet this need, TI developed Sub-1 GHz, as part of the SimpleLink MCU Platform, which allows you to jump into design, without starting from scratch. Kelsey explains the advantages of a Sub-1 GHz, what makes a robust network and the Sub-1 GHz 15.4 stack (IEEE 802.15.4e/g RF communication stack).
