Discussion and analysis of RadioWeaves architecture, including control mechanisms and requirements on analog and digital hardware, leading into energy models for both domains and energy efficiency case studies for both communication and power transfer. Conclusions regarding energy consumption for different deployment/design choices are drawn.

This report summarizes all dissemination and com-munication activities carried out since project start and addresses planned activities beyond project lifetime (update of D6.3).

D5.3 reports the concept validation and experimental results of the RadioWeaves technology, corresponding to the activities in Task 5.1 and Task 5.2 of REINDEER. In total, five experiments are conducted covering multiuser capabilities, low-latency and reliable communication, accurate positioning,
interacting (powering, communicating with, and positioning) with energy-neutral device (END), and reconfigurability with dynamic hardware resource allocation.

This deliverable consolidates experimental findings from D5.1 and D5.3 into a series of demonstration videos, offering a visual representation of key challenges and solutions addressed in REINDEER. These videos cover topics such as dynamic resource allocation, robustness versus latency trade-offs, accurate positioning, energy-neutral device interaction, and multi-user capabilities. Together, they highlight the advancements in distributed antenna systems and wireless power transfer technologies, offering new insights into the development of next-generation wireless ecosystems.

Detailed experimental validation plan, design of experiments, and definition of common formats. This report provides a detailed experimental validation plan. The design of experiments describes the distributed RadioWeaves topologies to be realized in the KU Leuven testbed and the particular experiments to be performed in the ULund testbed. D5.1 also defines formats for interfacing with RadioWeaves panels and for the exchange of experimental data.

Assessment of signalling schemes, protocols, and algorithms for energy-neutral devices. Quantitative assessment of wireless power transfer, high-rate communications, and accurate positioning with energy neutral devices, based on the designs described in D4.2.

This deliverable builds on the theoretical foundation formed in D3.1 and provides a more detailed analysis of robustness and latency aspects of the RadioWeaves concept. New methods are presented, covering robust beamforming, employment of constant envelope waveforms, support of environmental awareness, and scheduling and control mechanisms for dynamic environments.

Position estimation and environment learning. Report on fundamental performance limits for positioning, algorithm design and analysis for system calibration, positioning and synchronization as well as data fusion of information from radio infrastructure. An algorithm for environment sensing and learning exploits MIMO radar to infer mirror source locations.

This deliverable reports on the evaluation and design of hardware resources needed for transfer of energy to energyneutral nodes and backscattering-based connectivity to these nodes. The assessment of the hardware requirements takes energy efficiency as an important target, and includes different aspects such as synchronization, reciprocity calibration, and out-of-band constraints due to frontend non-linearities.

This deliverable provides estimates of distributed hardware resources, and their synchronization, needed to implement targeted algorithms for selected services and the associated requirements on back-haul data transfer between processing/hardware units.
