Bluetooth Relay Network for Location Tracking via RSSI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Bluetooth-based systems for content distribution and access in wireless networks face limitations in accurately tracking user location and delivering contextual content, especially in environments with signal interference and absorption by objects, such as humans and water, which affects the reliability and effectiveness of beacon communication.
Innovation Solution
The Bluefield apparatus employs a network of Bluetooth-enabled relay nodes, a parent module, and a cloud master to track user location and deliver content through a programmable internet-based server system, using RSSI measurements for triangulation and metadata collection, enabling self-monitoring, redundancy, and adaptive functionality to maintain robustness and accuracy in content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth beacons are used for location tracking and content delivery, then user location can be tracked and contextual content can be delivered, but signal interference and absorption by objects (humans, water) reduces reliability and effectiveness
Solution Approach 1:
The patent introduces intermediary devices (relay nodes, parent modules, cloud master) that mediate between Bluetooth beacons and end-user devices. These intermediaries receive, process, and forward location data and content, ensuring reliable communication even when direct beacon-to-device signals are blocked or interfered with by objects like humans or water.
Solution Approach 2:
The system implements feedback mechanisms where the cloud master receives location data from relay nodes, determines appropriate content based on location, and delivers it back to devices. This closed-loop feedback ensures that content delivery is continuously adjusted based on real-time location tracking, maintaining reliability despite signal challenges.
2Measurement precision
If multiple relay nodes are deployed for improved location tracking accuracy, then location precision improves, but system complexity and infrastructure requirements increase
Solution Approach 1:
The patent segments the location tracking system into hierarchical components: relay nodes that collect raw signal data, parent modules that aggregate data from multiple relay nodes, and a cloud master that performs final location calculation and content delivery. This segmentation allows precise location tracking through multiple distributed nodes while managing complexity through clear division of labor among system components.
