Vodafone and the Photonics and Radiofrequency Research Lab, at the University of Málaga, are developing photonic computer chips capable of directing a mobile signal straight to a user’s smartphone. The collaborators are using optical beamforming to process, steer, and focus mobile traffic, such as video streaming sessions, to the user. The use of the chips in smartphones, the team said, will provide increased accuracy, reduced signal loss, and limited interference. This collaboration is part of a project awarded to Vodafone under the European Commission’s Important Projects of Common European Interest Programme, supported by the Spanish Ministry of Industry and Tourism. Microwave photonic technology is emerging at an ideal time to benefit next-generation 5G-Advanced and future software-driven 6G networks. It is also better equipped for handling higher radio frequencies compared with current electronic systems.

Vodafone, supported by the University of Málaga, plans to publish a blueprint for photonic radio unit chips for mobile base stations within the next two years. The objective is to offer continuous streaming services without buffering, even in crowded areas. Optical beamforming technology is also expected to contribute to low-latency, high-bandwidth industrial applications such as autonomous vehicles and factory robotics. Advanced radar and direct-to-device satellite communication systems, which account for the Earth's curvature, will benefit from the beam steering capabilities. The team is developing two prototypes. The initial prototype involves a passive chip as part of the preliminary proof-of-concept work. Then, an enhanced active chip will be developed to replace the current beamforming component within a radio unit. Ultimately, Vodafone’s goal is to develop an improved optical radio unit. Upon completion of testing and validation for commercial network use, a fully functional beamforming chip will be capable of operating with up to 32 small radio antennas integrated into a single mast, with each antenna being individually controlled. This project aims to improve commercial communication networks using photonic beamforming radio units.
