  •  NEWS   Mitsubishi Electric and MERL Help Develop IEEE Smart Meter Coexistence Standards
    Date: April 23, 2021
    MERL Contacts: Jianlin Guo; Philip Orlik
    Research Areas: Communications, Electric Systems
    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
    • MELCO and MERL researchers have won "Excellent Presentation Award" at the IPSJ/CDS30 (Information Processing Society of Japan/Consumer Devices and Systems 30th conferences) held on January 25, 2021. The paper titled "Sub-1 GHz Coexistence Using Reinforcement Learning Based IEEE 802.11ah RAW Scheduling" addresses coexistence between IEEE 802.11ah and IEEE 802.15.4g systems in the Sub-1 GHz frequency bands. This paper proposes a novel method to allocate IEEE 802.11 RAW time slots using a Q-Learning technique. MERL and MELCO have been leading IEEE 802.19.3 coexistence standard development and this paper is a good candidate for future standard enhancement. The authors are Takenori Sumi, Yukimasa Nagai, Jianlin Guo, Philip Orlik, Tatsuya Yokoyama and Hiroshi Mineno.
