Summary Report of Generic R&D projects and evaluation of the approach. The WADAPT project.

To propagate the data following a collision, detectors use long cables going along the beam direction. Unfortunately, the material of the cables can degrade the precision of the measurement (scattering, nuclear interactions), impact the installation and suffer important latencies (axial readout). The WADAPT project proposes the use of wireless readout to transfer data. Wireless offers an elegant and cheaper option to cables. It allows ultra-low latency, direct communication between layers, radial readout and more flexibility in the transceiver placement. The 60 GHz band is adequate to transfer large amounts of data in both directions in real-time with minimum latency to a large number of individual devices, which otherwise will be impractical by using wire or optical connections, requiring to follow the construction. Commercial products are already available and have been tested for signal confinement, crosstalk, electromagnetic immunity, radiation hardness (up to 10^14 Neq/cm2). Initial antenna array prototype was successfully assembled, tested and finalized. Comprehensive study on antenna technologies was conducted, addressing the challenges of integration in high radiation and high-magnetic-field environments. The second prototype was assembled and validated featuring integrated low-power transceivers and embedded antennas. Substantial progress has been made toward complete system integration.  Besides, performance evaluation in a HEP environment is not yet completed. However, promising results were presented at the EuCAP 2025 conference in Stockholm. Technology is being prepared for dissemination to new users, and possible new collaborations. Final integration steps are underway at UU, targeting the demonstration of a 5 Gbps data rate using our custom-built demonstration boards.
