Low-power wide-area network (LPWAN)

Low-power wide-area network (LPWAN) is an emerging technology which provides long-range and wide-area communications with low-power consumption for the Internet of Things (IoT). Many techniques have already been proposed and developed to realise the LPWAN, such as SigFox, Narrowband IoT (NB-IoT), Long Range (LoRa), Random Phase Multiple Access (RPMA) and so on. Our research focuses on two aspects, namely, 1.) improving the LPWAN technology based on modern communication/information theory considering the needs of ubiquitous power Internet of Things; 2.) developing/adopting existing LPWAN techniques according to different requirements such that it can be applied to power transmission and distribution networks/facilities.

Ongoing Research Projects:

  • Research on Low Power Wide Area Industry IoT Communication Technology for State Monitoring in Power Distribution Network.
    • Efficient and effective cognitive radio technique for LPWAN.
    • Reliable and robust MAC layer protocol design of LPWAN for industry IoT.
    • Energy-efficient Network design based on optimal resource allocation.
  • Research and Development of Smart Sensors for Online Monitoring of Multi-physical Parameters in Ultra-High Voltage Direct Current (UHVDC) Converters.
    • Applicable LPWAN techniques for UHVDC Converters with complex wireless communication channel under harsh environment.
    • Ultra-low power sensor system design for UHVDC Converters.
    • Advanced Packaging solutions for smart sensors under harsh EMC conditions.

Interested topics:

  • Energy harvesting technologies and solutions.
  • Advanced packaging technologies, for example, System in Package (SiP).
  • New LPWAN design, optimisation and solutions.
  • Unmanned Aerial Vehicle (UAV) aided LPWAN.
