Abstract

Complex emerging wireless technologies with Gbps connectivity, such as the 5th generation (5G) and 6th generation (6G) of mobile networks, require improved and substantiating documentation for the wireless standards concerning the radio signals, systems, transmission environments used, and the radio frequency exposures created. Metrology has a pivotal role to ensure the product quality and the end-user confidence, and ultimately to improve the competitiveness of the telecommunications industry. Current challenges faced by the telecommunications sector include the lack of accurate, fast, low-cost, and traceable methods for the manufacturers to demonstrate 5G/6G product verifications matching the customer specifications.

In support of the above, a Joint Research Project “MEWS” (metrology for emerging wireless standards) [1] is launched in the framework of the new EURAMET (European Association of National Metrology Institute) European Partnership on Metrology programme. This project involves 17 partners including 5 European NMIs together with the academy and global industrial manufacturers. It addresses the emerging wireless products that underpin the 5G and 6G of mobile technologies, and aims to support the current and future standardization work by developing practical and efficient traceable measurement methods from which the standards under development can be built.

The planned developments concern three aspects. The first one is to develop traceable and cost-effective new radio (NR) over-the-air (OTA) measurements of sub-6 GHz and mm-wave multi-input-multi-output (MIMO) systems [2], implementing multi-probe anechoic chamber (MPAC), radiated two-stage (RTS), reverberation chamber plus channel emulator (RC+CE) [3] and mid-field methods. The second one concerns the characterization of the complex real-world sub-THz wide bandwidth antenna and radio propagation channel [4]-[5] for the planning of the short to medium range wireless communication and active services operating up to 750 GHz for the practical realization of the 5G/6G communications. Finally, the third aspect is the development of the measurement protocols to quantify RF exposure levels from 5G base stations by measuring power density (PD) and from mobile phones by measuring specific absorption rate (SAR) and absorbed power density (APD).

This paper gives an update on the recent activities from MEWS project. All these developments and the corresponding results are to be inputted to the relevant standard committees and the users of the developed standards, with the aim of incorporating them into the corresponding standards under development. This will have direct outcomes on wireless communications and electronics industries by ensuring the product quality and the end-user confidence.
