Solution Overview
Problem
Existing wireless communication systems face challenges in overcoming signal blockages at higher frequencies due to obstacles like buildings and trees, leading to increased infrastructure costs for additional base stations, and require efficient data management and integrity assurance for reconfigurable intelligent surfaces (metasurfaces) to ensure secure and authorized access to rights-managed data.
Innovation Solution
Implementing reconfigurable intelligent surfaces with AI-driven control, coupled to tile controllers and a centralized controller, that manage signal reflection or absorption based on real-time authentication and access rights, using a decentralized blockchain network and identity and access management system to ensure secure data access and integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large number of base stations are installed to provide coverage to blocked areas, then wireless signal coverage is improved, but infrastructure costs increase many times
Solution Approach 1:
The patent introduces metasurfaces as intermediary devices that manipulate electromagnetic waves to provide coverage in blocked areas without requiring additional base stations. These thin reflective or refractive surfaces act as mediators between the base station and the blocked reception areas, redirecting signals around obstacles like buildings and trees.
Solution Approach 2:
The patent uses metasurfaces to create virtual copies of base station coverage areas by reflecting and refracting signals. Instead of physically installing additional base stations, the system creates virtual coverage zones using programmable electromagnetic manipulation, effectively copying the coverage function at a fraction of the cost.
2Reliability
If reconfigurable intelligent surfaces are used to manipulate electromagnetic waves, then signal coverage in blocked areas is improved, but data security and access control requirements increase
Solution Approach 1:
The patent segments the metasurface into multiple independently controllable unit cells, each capable of being configured separately. This segmentation allows for fine-grained control over signal manipulation while also enabling distributed data management, where each unit cell or group of unit cells can be controlled and authenticated independently, reducing the complexity of managing the entire surface as a single entity.
Solution Approach 2:
The patent implements dynamic reconfiguration of the metasurface based on real-time authentication results. The system can dynamically change the state of unit cells to grant or deny access, redirect signals, or absorb electromagnetic waves. This dynamic behavior allows the system to adapt to changing security requirements while maintaining signal coverage functionality.
3Reliability
If real-time authentication and access control are implemented for metasurfaces, then data security is improved, but system complexity and processing time increase
Solution Approach 1:
The patent implements preliminary authentication mechanisms where access credentials are verified before the metasurface is activated or before signal manipulation begins. By performing authentication in advance, the system ensures security is established before any signal processing occurs, preventing unauthorized access while maintaining efficient real-time operation once authenticated.
Solution Approach 2:
The patent incorporates feedback loops where the system continuously monitors authentication status and adjusts metasurface configuration accordingly. The controller receives feedback about access attempts and dynamically reconfigures the unit cells to grant or deny signal manipulation permissions. This closed-loop feedback mechanism maintains security while enabling efficient real-time control.

Data Source
AI summary
The technology described herein is directed towards rights management and integrity assurance of data for reconfigurable intelligent surfaces (metasurfaces), such as quality of experience data metrics and tile controller configuration data for configuring metasurfaces, including configurations based on artificial intelligence. Incoming signals impinging on the metasurface corresponding to rights-managed data are reflected by the metasurface as distorted signals, while authentication for access to this data is pending. An identity and access management system can be used for authentication. If access is granted, the metasurface is controlled to transmit non-distorted signals to the authenticated receiver. If access is denied, the metasurface is controlled to absorb the incoming signals. Further, information related to rights-managed data access can be recorded as a transaction in a decentralized block chain network. Path integrity to detect potential eavesdroppers can be performed, such as based on artificial intelligence generative adversarial network models.
