Cellular-Ubiety Identifier Indoor Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current indoor locationing technologies lack a global reference system and are not ubiquitous, as they rely on installed beacons or GPS, which are limited in accuracy and penetration, especially in indoor environments, failing to provide high-precision positioning across all smartphones and applications.
Innovation Solution
The implementation of Cellular-Ubiety identifiers, which use high-precision real-time N-dimensional relative Time of Arrival, Timing Difference of Arrival, and Reference Signal Receive Power measurements from multiple cellular transceivers to define and map user equipment positional data to customer-defined locations, eliminating the need for absolute reference solutions like GPS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If GPS or global positioning systems are used for outdoor locationing, then global coverage is achieved, but indoor positioning accuracy deteriorates due to signal penetration limitations
Solution Approach 1:
The patent segments the positioning system into outdoor GPS-based positioning and indoor cellular-based positioning. The cellular network is divided into multiple transceivers, each covering specific indoor areas, allowing the system to switch between global outdoor coverage and precise indoor localization without signal penetration issues
Solution Approach 2:
The patent introduces cellular transceivers as intermediary devices for indoor positioning. These transceivers act as mediators between the user equipment and the positioning system, providing reference signals that enable accurate indoor location determination without relying on GPS signals that cannot penetrate buildings
2Measurement precision
If beacon technologies are deployed for indoor locationing, then relative location identification is improved, but device complexity increases due to installation requirements
Solution Approach 1:
The patent makes the cellular network universally applicable for both outdoor and indoor positioning. The existing cellular infrastructure is leveraged to provide positioning services without requiring separate beacon installations, making the system universal across different environments and eliminating the need for additional dedicated positioning devices
Solution Approach 2:
The patent enables the cellular network to self-serve positioning functions. The cellular transceivers that already provide communication services also provide positioning reference signals, allowing the system to use existing infrastructure for dual purposes without additional installation complexity or dedicated positioning hardware
3Measurement precision
If WiFi locationing solutions are implemented, then indoor positioning capability is improved, but adaptability deteriorates due to lack of global reference system
Solution Approach 1:
The patent makes the cellular network universally applicable for both outdoor and indoor positioning. The cellular transceivers that already provide communication services also provide positioning reference signals, allowing the system to use existing infrastructure for dual purposes without additional installation complexity
Solution Approach 2:
The patent performs preliminary configuration of cellular transceiver locations and characteristics before positioning operations. The network maintains pre-established knowledge of transceiver positions and signal characteristics, enabling immediate positioning functionality without requiring real-time calibration or reference system setup
4Measurement precision
If multiple transceivers are deployed for high-precision positioning, then positioning accuracy is improved, but loss of substance increases due to infrastructure requirements
Solution Approach 1:
The patent makes the cellular network universally applicable for both outdoor and indoor positioning. The existing cellular infrastructure is leveraged to provide positioning services without requiring separate beacon installations, providing global coverage while using already-deployed resources
Solution Approach 2:
The patent merges communication and positioning functions into a single cellular network infrastructure. The same transceivers that provide communication services also provide positioning reference signals, combining multiple functions into one system and eliminating the need for separate positioning infrastructure
