In order to carry out the development of 5G technology, a knowledge of wave propagation in these new environments is necessary. In this context, the TELICE group of IEMN conducted in July 2020 a first V2I (Vehicule to Infrastructure) channel sounding campaign with the Massive Multiple Input Multiple Output System Acquisition (MaMIMOSA) real-time radio channel sounder. The results of the first measurement campaign will be presented in March 2021 at the 15th EuCAP 2021 (European Conference on Antenna and Propagation).

MaMIMOSA has been jointly designed by the University of Lille IEMN TELICE and the University of Ghent (Belgium). The objective is the study of propagation phenomena in wireless communications and V2X 5G applications. These studies are carried out within the framework of the CPER (Contrat de plan Etat Région) ELSAT2020 and the activities of the IEMN « Transport » Flagship. This equipment is an integral part of the C2EM cluster of the University of Lille and IEMN PCMP (Multi-Physics Characterization Platform for micro/nano devices, high frequency components and communicating systems).

The system is equipped with an array of 64 antennas for transmission and up to 16 individual antennas can be deployed for reception. Due to its flexibility, MaMIMOSA allows to freely adapt the channel probing parameters to the studied scenario. The radio channels were measured at 5.89 GHz with a bandwidth of 80 MHz on the campus of the University of Lille at a vehicle speed of up to 60 km/h. In addition to this suburban mobility scenario, static radio channels obstructed by vegetation were collected from a parked vehicle. These data will allow the study of the influence of vegetation on communications. Preliminary Doppler characteristics are reported from the measured radio channels.
