Solution Overview
Problem
Current wireless local area network (WLAN) sensing methods face challenges in efficiently establishing measurement setups, leading to increased network load and processing complexity, particularly in optimizing the detection of persons or objects within environments using scattered and reflected WLAN signals.
Innovation Solution
A sensing method involving an SBP requester and an SBP responder, where the SBP requester transmits a request frame to the SBP responder to establish measurement setups, and the responder responds with a frame to confirm or reject the setup, optimizing the measurement setup process to reduce network load and processing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional WLAN sensing methods are used to establish measurement setups, then sensing functionality can be achieved, but network load and processing complexity increase
Solution Approach 1:
The patent introduces a sensing proxy device as an intermediary between the WLAN network and the sensing target. The proxy device receives sensing requests, establishes measurement setups with sensing responders, and forwards results to the original requester. This intermediary structure reduces the processing burden on network devices while maintaining full sensing functionality, directly addressing the contradiction between reliability and complexity.
2Reliability
If traditional WLAN sensing methods are used to establish measurement setups, then sensing functionality can be achieved, but network load increases
Solution Approach 1:
The sensing proxy device acts as a mediator that consolidates multiple sensing requests and manages measurement setup establishment. By centralizing this functionality in the proxy, the patent reduces the number of direct communication interactions between multiple network devices and sensing responders, thereby reducing overall network load while preserving sensing functionality.
Solution Approach 2:
The patent merges the functions of receiving sensing requests, establishing measurement setups, and managing sensing operations into a single sensing proxy device. This consolidation reduces the distributed network traffic and processing overhead that would occur if multiple devices performed these functions independently, thus reducing network load while maintaining sensing capabilities.
