Brief - IoT applications such as smart metering system are rapidly increasing. A broad range of low power wide area communication technologies have been developed. These systems all operate in frequencies below 1 GHz, commonly called Sub-1 GHz frequency bands, to meet various application requirements. Several communication standards and proprietary technologies already use the Sub-1 GHz bands: IEEE 802.15.4g (Wi-SUN), IEEE 802.11ah (Wi-Fi HaLow), LoRa, SigFox and RFID. Due to limited spectrum in the Sub-1 GHz frequency bands, it is likely that applications will compete for the same resources and interfere with one another. This is a particular issue in Japan where the amount of license-exempt Sub-1 GHz frequencies is more limited than in other regulatory regions. Therefore, the coexistence becomes an issue to be addressed. Accordingly, IEEE New Standards Committee and Standard Board formed IEEE 802.19.3 Task Group in 2018 to develop guidelines and best practices for the coexistence of IEEE 802.11 and IEEE 802.15.4 based systems and to guide product deployment. MERL member Jianlin Guo took a lead role as Task Group Technical Editor, and was supported by Mitsubishi Electric Corporation researchers Yukimasa Nagai, Takenori Sumi and consultant Benjamin A. Rolfe (Task Group Chair) in the development of this standard. As of April 2021 a new standard recommended practice document, IEEE Recommended Practice for Local and Metropolitan Area Networks—Part 19: Coexistence Methods for IEEE 802.11 and IEEE 802.15.4 Based Systems Operating in the Sub‐1 GHz Frequency Bands, was published. This will help guide future IoT/smart metering system deployment. The standard is widely available for download from the IEEE Standards Association at https://standards.ieee.org/standard/802_19_3-2021.html.

Brief 
The evolution of the grid faces significant challenges if it is to integrate and accept more energy from renewable generation and other Distributed Energy Resources (DERs). To maintain grid's reliability and turn intermittent power sources into major contributors to the U.S. energy mix, we have to think about the grid differently and design it to be smarter and more flexible.
ARPA-E is interested in disruptive technologies that enable increased integration of DERs by real-time adaptation while maintaining grid reliability and reducing cost for customers with smart technologies. The potential impact is significant, with projected annual energy savings of more than 3 quadrillion BTU and annual CO2 emissions reductions of more than 250 million metric tons.
This talk will identify opportunities in developing next generation control technologies and grid operation paradigms that address these challenges and enable secure, stable, and reliable transmission and distribution of electrical power. Summary of newly announced ARPA-E NODES (Network Optimized Distributed Energy Systems) Program funding development of these technologies will be presented.
