Indoor Transit Navigation Using BLE Beacons and Detailed Maps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems for mobile devices are ineffective in indoor environments due to the unreliability of GPS, cellular, and WiFi signals, and lack of detailed indoor maps, making it difficult for users to navigate indoor transit systems such as skyway and subway systems.
Innovation Solution
A mobile application that utilizes Bluetooth beacons distributed throughout indoor transit systems to determine the user's location and provide detailed indoor maps, allowing for route planning and navigation within these systems, switching to outdoor maps when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GPS, cellular, and WiFi signals are used for navigation, then outdoor navigation is effective, but indoor navigation becomes unreliable
Solution Approach 1:
The patent introduces Bluetooth Low Energy (BLE) beacons as intermediary devices distributed throughout the indoor transit system. These beacons serve as mediators between the mobile device and the indoor environment, enabling location determination when traditional GPS, cellular, and WiFi signals become weak or unavailable indoors. The mobile device detects and communicates with these beacon intermediaries to maintain navigation reliability in indoor settings.
2Area of stationary object
If outdoor maps are used for navigation, then outdoor areas are covered, but indoor spaces lack sufficient detail
Solution Approach 1:
The patent divides the mapping system into separate outdoor and indoor map components. Outdoor maps provide general geographic coverage using traditional mapping data, while dedicated indoor maps provide detailed information about indoor transit system pathways, connections, and landmarks. This segmentation allows each map type to be optimized for its specific environment without compromising the other.
Solution Approach 2:
The patent transitions from two-dimensional outdoor maps to three-dimensional indoor maps that represent complex indoor pathways and spatial relationships. The indoor maps include detailed information about skyway connections, subway station layouts, and indoor navigation routes that cannot be adequately represented in traditional flat outdoor maps.
3Measurement precision
If traditional location services are used, then outdoor positioning is accurate, but indoor positioning becomes ineffective
Solution Approach 1:
The patent replaces the satellite-based GPS mechanical system with a ground-based BLE beacon system for indoor positioning. Instead of relying on signals from space that penetrate weakly through buildings, the system uses locally generated radio frequency signals from beacons distributed throughout the indoor environment, providing accurate position measurement independent of satellite signal availability.
4Device complexity
If a unified navigation system is used, then system complexity is low, but adaptability to different environments is limited
Solution Approach 1:
The patent implements a dynamic navigation system that automatically adapts its operation mode based on the detected environment. The system transitions between outdoor GPS-based navigation and indoor beacon-based navigation seamlessly, adjusting its behavior according to signal availability and location context. This dynamic adaptation allows a single system to handle multiple environments effectively without requiring manual configuration.
Solution Approach 2:
The patent creates a universal navigation application that performs both outdoor and indoor navigation functions through a single interface. The app automatically detects whether the user is in an outdoor or indoor environment and switches between appropriate positioning methods (GPS/cellular/WiFi for outdoor, BLE beacons for indoor), providing consistent navigation services across diverse environments without requiring separate applications.

AI summary
Devices, methods, and systems for navigating an indoor area such as an indoor transit system using a mobile device are described herein. The method may include navigating a network of indoor pathways and a plurality of access points for entering/exiting the indoor pathways. The indoor pathways may be mapped and may include a plurality of beacons distributed at designated locations throughout the indoor pathways. The beacons may be detected using a mobile computing device and an indoor location of the mobile computing device may be determined and depicted on the map of the indoor pathways. The location of the mobile computing device may be used to determine a route from the location of the mobile computing device to a destination in or adjacent the mapped indoor pathways.
