Enterprise Server Indoor Location Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location mechanisms for user devices, such as cellular and WiFi signals, often result in a large margin of error, making it difficult for emergency services to accurately locate a user device within an enterprise setting, such as an office building or campus, especially when the device is not connected to the enterprise's wireless system.
Innovation Solution
An enterprise server coordinates with a Public-Safety Answering Point (PSAP) to determine a precise location of a user device within an enterprise by verifying the general location and using additional location mechanisms like WiFi network signal strengths and NFC components to pinpoint the device's location, enabling more accurate emergency service dispatch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cellular signals are used to determine location, then the location can be obtained with coverage area, but the margin of error is relatively large
Solution Approach 1:
The patent combines multiple location mechanisms (cellular signals, WiFi signals, and enterprise-specific location systems) into a unified location determination approach. By merging these different signal sources and methodologies, the system achieves both broad coverage through cellular networks and high precision through enterprise-specific mechanisms, resolving the contradiction between coverage area and location precision.
2Measurement precision
If only two-dimensional geographic location is provided, then emergency services can be dispatched to general area, but precise location inside building or campus cannot be determined
Solution Approach 1:
The patent transitions from two-dimensional geographic coordinates to three-dimensional location information by incorporating floor level, building structure, and enterprise-specific spatial data. This dimensional expansion allows emergency services to locate devices not just by latitude and longitude, but also by vertical position and building context, achieving precise indoor localization while maintaining comprehensive location information.
3Measurement precision
If enterprise-specific location system is implemented, then precise location within enterprise can be determined, but system complexity increases
Solution Approach 1:
The patent introduces an enterprise server as an intermediary component that bridges the user device and the location determination process. This intermediary handles the complex tasks of receiving contact data, determining precise location within the enterprise, and coordinating with PSAP, thereby managing system complexity in a centralized manner while enabling precise location determination without burdening individual devices.
4Measurement precision
If enterprise server coordinates with PSAP using multiple location mechanisms, then location accuracy is improved, but information processing requirements increase
Solution Approach 1:
The patent implements preliminary action by having the enterprise server determine the precise location of the user device within the enterprise before final emergency service dispatch. By performing this location determination in advance and coordinating with PSAP proactively, the system processes location information efficiently, reducing the burden of real-time data processing during critical emergency situations while maintaining high location accuracy.
