This project will produce metrological methods for evaluating wireless system performance and uncertainty. It will develop and test three traceable channel sounding testbeds for evaluating radio propagation in the environment and verify their performances in real-world scenarios, using modelling to validate results and generating an open access results database for use in the planning of short/medium-range wireless communication. It will develop a measurement methodology and good practice guide for exposure levels from 5G base stations and mobile phones, which will be submitted for consideration as contributions to IEC 62232 and IEC 62669. The results of this project will enable efficient and traceable measurements for wireless networks. This will accelerate the uptake and development of 5G/6G technology and improve human and environmental safety through improved understanding of RF exposure from wireless systems.
