This video shows a trial test in Barcelona city last September 2020 under the project 5GCroco. 5GCroCo project aims at defining successful path towards the provision of cooperative, connected and automated mobility (CCAM) services along cross-border scenarios and reduce the uncertainties of a real 5G cross-border deployment. The Barcelona small-scale trial site is composed of a 5G neutral hosting platform deployed in Barcelona (in the 22@ district), and an emulated cross-border Internet Exchange Point (IXP) platform deployed at CTTC.

The vehicles used in the Barcelona trial site are equipped with a car PC system which can be used as Communications Control Unit (CCU) in any vehicle. The core of the car PC is a laptop that uses Linux and a software application based on OpenC2X, an open-source software that supports ITS protocol stack. The car PC communicates with the backend over 4G LTE, it is connected to a GNSS (Global Navigation Satellite System) receiver to obtain the real-time position of the vehicle and to the CAN bus of the vehicle by means of an On-Board Diagnostic (OBD) interface adapter or a CAN to USB adapter.

The main concepts to illustrate are:

• A 5G neutral hosting platform composed of three lampposts with LTE small cells at 3.5 GHz.
• An IXP platform where multiple vMNOs can exchange data traffic.
• A car PC configured as vehicle emulator.
• An Edge MQTT broker able to receive and send JSON messages.
• An Edge Dynamic Map (EDM) database to detected hazard events.
• An end-to-end orchestration handled by the Service Orchestrator (SO) and the Multi-domain Orchestrator (MDO).
