Wireless Link Snooping via Broadcast Parameters for Multi-Device Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems are limited by the number of devices that can be connected via wireless links, such as Bluetooth's 7-device limit, and wireless mesh networks suffer from reduced real-time performance and reliability.
Innovation Solution
A first wireless device establishes a connection with a data source and broadcasts parameters to enable multiple second wireless devices to snoop the link, using encryption or direct broadcasting to configure data modes and receive service data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If point-to-point wireless link connection is established between devices, then reliable communication is achieved, but the number of connected devices is limited (e.g., Bluetooth limit of 7 slave devices)
Solution Approach 1:
The first wireless device acts as an intermediary between the data source end and multiple second wireless devices. It establishes a wireless link with the data source end and broadcasts link parameters to enable second devices to snoop the link, thus mediating the connection between one data source and multiple receiving devices without requiring direct point-to-point connections between all pairs.
Solution Approach 2:
The system segments the communication function into two parts: (1) the first wireless device establishes and manages the wireless link with the data source end, and (2) multiple second wireless devices independently snoop the broadcast parameters to access the link. This segmentation allows one link to serve multiple devices simultaneously.
2Quantity of substance
If wireless mesh network is used to connect multiple devices, then device connectivity is improved, but real-time performance and reliability deteriorate
Solution Approach 1:
The first wireless device serves as a dedicated intermediary that maintains a direct wireless link with the data source end and broadcasts parameters to multiple second devices. This eliminates the need for complex mesh routing between devices, reducing transmission hops and improving real-time performance while maintaining high device connectivity.
3Object-affected harmful factors
If encryption algorithm is used to protect wireless link parameters, then security is improved, but processing complexity increases
Solution Approach 1:
The first wireless device broadcasts copies of the wireless link parameters to multiple second wireless devices. Each second device receives and processes identical parameter copies independently, eliminating the need for complex individualized encryption/decryption processes for each device while maintaining security through parameter protection.

AI summary
A wireless device snooping method includes: a first wireless device establishing a wireless link connection with a data source end, and generating corresponding wireless link parameter(s); and the first wireless device broadcasting the wireless link parameter(s) to trigger at least one second wireless device to receive the wireless link parameter(s) and snoop the wireless link on the basis of the wireless link parameter(s). In this way, in the present disclosure, the first wireless device transmits the wireless link parameter(s) to at least one second wireless device by means of broadcast, thereby breaking through the limitation in the number of second wireless devices, so that a plurality of second wireless devices simultaneously snoop a wireless link, improving the real-time performance and reliability of transmission.
