MP6R Controller (MP6RC) serving as the brain of the MP6R system, to i) coordinate and control multi-technology integration and mobility management of the sensing objects inside the RAN; and ii) interface and manage distributed DASH nodes throughout the RAN for handling multi-sensor, multi-connectivity, and multi-technology data integration. Data Access and Security Hub (DASH) designed as a novel RAN data plane entity that aggregates multi-sensor data of diverse technologies, providing secure data access, processing, storage, and exposure, ensuring data privacy and trustworthiness, and that can be fully distributed throughout the data plane wherever needed in the 6G-RAN. 6 MultiX Perception System (MPS) •Unified ISAC channel models for multitechnology and multi-band perception •Signal processing algorithms that, leveraging on such unified channel models, provide multiband ISAC functionalities •Multi-static sensing through distributed MIMO to achieve high perception resolution through multi-static signal processing techniques. •Multi-modulation–based sensing exploiting OFDM or OTFS modulated signals. •Design of novel Energy-efficient AI architectures for adaptive, event-based ISAC receivers and distributed learning from multistatic sensing devices 7 Data Access and Security Hub (DASH) To develop a full distributed and secure Data pipeline, responsible for secure data collection, aggregation, and distribution. 8 Proposed architecture (v1.3) 9 Enabling P-Sensing on Multiband WLAN Networks 16 Reusing WLAN signaling to perform environmental sensing on 5 GHz and 60 GHz Enabling P-Sensing on Multiband WLAN Networks 17 Scenario 1: Corridor path tracking Scenario 2: Laboratory presence monitor MultiX Project THANKS!
