Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RF-based sensing systems require complex user input for configuring multiple nodes, deterring users from utilizing their full potential due to initial configuration complexity.
Innovation Solution
A system and method that automatically configures RF-based sensing nodes into groups based on their current access points, allowing nodes to transmit and receive signals within their respective groups without manual user input, using processors to determine and assign nodes to groups or subgroups based on link quality and access point suitability.

1Reliability
If manual configuration of sensing nodes is required, then sensing system performance can be optimized, but user complexity and configuration difficulty increase significantly
Solution Approach 1:
The system automatically configures sensing nodes by having them self-identify their locations based on which access points they can detect. Nodes autonomously determine their group assignments without user intervention, yet the system maintains optimized sensing performance through automatic spatial grouping based on actual node positions.
Solution Approach 2:
The system changes the configuration parameter from manual location specification to automatic detection-based grouping. By monitoring which access points each node can detect, the system dynamically determines node locations and automatically creates optimal sensing groups, eliminating complex manual configuration while maintaining performance.
2Area of stationary object
If multiple access points are deployed to improve coverage, then sensing coverage area increases, but system complexity and node management difficulty increase
Solution Approach 1:
The system segments the sensing network into multiple groups, each associated with a specific access point. Nodes are automatically assigned to groups based on which access point they can detect, creating manageable sub-networks that reduce overall system complexity while collectively covering a larger area through the distributed access points.
Solution Approach 2:
Access points serve as intermediaries that facilitate node grouping and management. Instead of directly managing all node relationships, the system uses access points as mediators to automatically organize nodes into groups, simplifying the management of multi-access point systems while expanding coverage area.

AI summary
A system (1) for configuring an RF-based sensing system is arranged to obtain connection information from sensing nodes (31-35, 41-45) of the RF-based sensing system and/or from access points (13, 14) with which the sensing nodes are associated and determine, based on the connection information, a current access point for each of the sensing nodes. The system is further arranged to assign each of the sensing nodes to a group based on the current access point determined for the respective sensing node and configure the RF-based sensing system to use this assignment. Each of the sensing nodes is configured to transmit and/or receive RF signals for the RF-based sensing to and/or from one or more other sensing nodes in the respective sensing node's group.
