Private Wireless Networks for Automotive: spectrum analysis in 5G frequency bands

5G technology represents an unprecedented innovation for verticals ensuring uninterrupted connectivity even in the event of high traffic levels, as well as delivering the speeds needed for mobile broadband and IoT-based services. The sectors most involved are the Industrial IoT which will benefit from the automation of production processes and remote monitoring, systems for smart cities and the automotive sector thanks to the possibility of remote driving. The paper presents technology challenges to realize private networks for vertical applications, including automotive, based on 5G networks. We address spectrum requirements and coexistence issues in private wireless networks for automotive vertical applications mainly focusing on the 6 GHz band. The impact of local private networks on incumbent services is presented, through the FUB proprietary tool which provides coexistence studies in macro-urban and suburban scenarios, considering and comparing different propagation models.
