Location Server Triggering Actions via RF Signal Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack an efficient method to leverage data from user devices and communication networks to trigger actions in specific areas, such as controlling environmental systems or security measures, based on signal strength and density profiles.
Innovation Solution
An access point with sensors detects RF signals from user devices and transmits them to a location server, which determines signal strength and density, triggering corresponding actions when thresholds are met, such as activating HVAC or security systems, by querying network carriers for detailed device information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sensors detect RF signals from user devices and transmit to location server for analysis, then granular control of systems is enabled and resource usage is optimized, but device complexity and system integration requirements increase
Solution Approach 1:
The patent introduces a location server as an intermediary component that receives RF signal data from access points, queries network carriers for device information, and determines whether to trigger actions. This mediator architecture distributes system complexity across multiple specialized components rather than requiring a single complex device, enabling granular control while managing overall system complexity through functional decomposition.
2Extent of automation
If signal strength threshold triggering is implemented for HVAC or security systems, then automated control is achieved, but measurement precision requirements increase
Solution Approach 1:
The system implements automated control by detecting whether signal strength exceeds a predetermined threshold, rather than requiring continuous precise measurement and control. This partial action approach triggers discrete actions (activate/deactivate systems) based on threshold crossing, reducing measurement precision requirements while maintaining effective automation for environmental and security control.
3Measurement precision
If network carrier data querying is performed for device information, then device presence detection accuracy is improved, but loss of time increases due to additional communication steps
Solution Approach 1:
The location server queries network carriers for user device data in advance of making final determination about triggering actions. By performing this data retrieval operation beforehand, the system ensures accurate device presence detection is available when needed, while the preliminary timing of the query helps manage the overall response time by initiating data collection as early as possible in the decision process.

AI summary
Systems and methods provide for triggering an action based on detection of one or more user devices. One or more signals from at least one user device are detected by at least one sensor in a target area. A sensor can be in operable communication with a location server to which the signals are relayed. Based on the signals detected, a determination is made as to whether the one or more signals exceed a predetermined threshold for signal strength in the target area. Based on a set of signals exceeding the predetermined threshold for signal strength, the location server triggers an action that corresponds to the target area.
