A wireless location service system that integrates wireless access points, a WLAN controller, a server, and a database to identify facilities and mobile devices' locations, and presents messages as virtual graffiti based on proximity, time, and address information, using RF fingerprinting and triangulation for accurate location determination, and augmented reality for message display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless systems use general message delivery methods, then message transmission can be achieved, but location-based targeted message delivery to mobile devices in proximity to specific facilities cannot be effectively implemented
Solution Approach 1:
The patent implements a nested architecture where wireless access points are nested within the facility infrastructure, the WLAN controller is nested within the network infrastructure, and the message delivery system is nested within the location service framework. This nesting allows location-based message delivery functionality to be integrated into existing wireless infrastructure without requiring separate standalone systems, thereby improving adaptability while managing complexity.
Solution Approach 2:
The wireless access points and WLAN controller are designed to serve multiple functions: providing general wireless connectivity, enabling location identification through RF fingerprinting and triangulation, and supporting targeted message delivery. This multi-functionality allows the same infrastructure to handle both general communication and location-based services, improving versatility without proportionally increasing system complexity.
2Measurement precision
If the system implements comprehensive location identification services with RF fingerprinting and triangulation, then accurate location determination is achieved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary actions by pre-collecting RF fingerprint data from multiple access points and pre-calculating triangulation parameters during system setup and idle periods. When a mobile device needs location determination, the pre-processed data is readily available, significantly reducing the processing time required for accurate location identification while maintaining measurement precision.
Solution Approach 2:
The location determination process is segmented into independent modules: RF signal strength measurement, fingerprint matching, and triangulation calculation. Each module processes data independently and can be executed in parallel or cached separately. This segmentation allows the system to achieve accurate location determination while minimizing processing time by avoiding redundant computations and enabling selective execution of location methods.
3Adaptability or versatility
If the system delivers messages to all mobile devices in range, then message coverage is maximized, but targeted message delivery to specific facilities cannot be achieved
Solution Approach 1:
The system implements local quality by associating specific messages with specific facility locations rather than broadcasting to all devices uniformly. Each message is tagged with location identifiers (facility ID, coordinates) and is delivered only to mobile devices whose determined location matches the message's target facility. This approach enables precise targeted delivery while minimizing unnecessary message traffic to devices outside the target area.
Solution Approach 2:
The system uses feedback from location determination results to control message delivery decisions. After determining a mobile device's location through RF fingerprinting or triangulation, the system feedbacks this location information to the message delivery logic, which then decides whether to deliver the message based on the match between the device's location and the message's target facility. This feedback mechanism ensures targeted delivery while reducing overall message traffic volume.
4Adaptability or versatility
If the system integrates multiple components (access points, controller, server, database), then location-based message delivery functionality is enhanced, but system complexity and deployment difficulty increase
Solution Approach 1:
The WLAN controller serves as an intermediary component that mediates between the wireless access points (which collect RF data) and the server (which performs location calculation and message delivery). The controller aggregates data from multiple access points, manages the fingerprint database, and coordinates triangulation computations. This intermediary architecture enhances location service functionality by centralizing control while simplifying deployment, as the controller can be configured to work with various access point types and server implementations.
Solution Approach 2:
The patent merges multiple functions into the WLAN controller to reduce deployment complexity: access point management, fingerprint database maintenance, location calculation coordination, and message delivery routing are all combined in a single controller component. This merging reduces the number of separate deployment entities from five (access points, controller, server, database, message gateway) to effectively four, with the controller absorbing multiple responsibilities. The result is enhanced functionality while improving ease of deployment and system integration.

AI summary
Systems, methods, and apparatus may perform operations related to delivering wireless information associating to a facility. A message is received from a first mobile device with at least a portion of the message including information associated with a physical location. Based on the message, a facility based on the physical location is identified. The message may be associated with the facility. An indication is received that a second mobile device is proximate to the facility and engaged in a message browsing mode. Based on receiving the indication, the message may be presented to the second mobile device.
