  In an increasingly connected world, wireless networks' monitoring and
characterization are of vital importance. Service and application providers
need to have a detailed understanding of network performance to offer new
solutions tailored to the needs of today's society. In the context of mobility,
in-vehicle infotainment services are expected to stand out among other popular
connected vehicle services, so it is essential that communication networks are
able to satisfy the Quality of Service (QoS) and Quality of Experience (QoE)
requirements needed for these type of services. This paper investigates a
multi-layer network performance monitoring architecture at the edge providing
QoS, QoE, and localization information for vehicular video streaming
applications in real-time over 5G networks. In order to conduct field trials
and show test results, Mobile Network Operators (MNOs)' 5G Standalone (SA)
network and Multi-access Edge Computing (MEC) infrastructure are used to
provide connectivity and edge computing resources to a vehicle equipped with a
5G modem.
