Title: Recent R&D activities on metrology for emerging wireless technologies at the UK National Physical Laboratory

Abstract:
A raft of advanced wireless technologies for 5G and beyond is increasingly emerging in the arena of modern new radio (NR) wireless communication devices and systems design. This includes the utilization of large-scale antenna configuration, millimetre wave (mm-wave), sub-THz and optical frequencies. This talk presents an overview of the measurement challenges of over-the-air (OTA), RF exposure and propagation channel for emerging wireless technologies, the relevant international activities as well as the measurements capabilities at NPL established under several UK and EU programmes. The topics covered include massive multiple-input-multiple-output (MIMO), MIMO-OTA, mm-wave hybrid beamforming with large-scale phased arrays, data handling for 3D holographic displays application using mm-wave and light fidelity (Li-Fi) techniques, location-awareness full mesh internet-of-things (IoT) network for indoor and outdoor scenarios, connected autonomous vehicles (CAV) communications, novel 5G antenna designs, reconfigurable intelligent surfaces, etc.
