Deliverable D3.1 - Intermediate V2V and V2I OWC prototypes

This deliverable presents the transceiver sub-systems serving optical wireless technology within the 6G-EWOC project. It discusses the use of vehicle-to-vehicle, vehicle-to-infrastructure and infrastructure-to-infrastructure modes that support data exchange over the air by means of optical communication technology, both as dedicated comms-only system or in combination with lighting or sensing. To support these modes, pencil- and wide-beam schemes are being employed. Besides a preliminary performance characterization for several optical wireless communication sub-systems, the deliverable further covers aspects such as mobility and robustness to weather. The developed prototypes for all wireless application modes are presented, including transmitters sourced by lasers and light emitting diodes, receivers based on highly sensitive avalanche photodetectors, together with beamformers for pencil-beam steering and alignmenttolerant and turbulence-mitigated signal reception, joint communication and sensing systems for light- and radio-based detection and ranging, as well as hybrid radio/optical wireless implementations.
