Localized Access Points for Granular Mobile Device Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional GPS-based systems for detecting mobile device presence are costly, power-intensive, and lack sufficient granularity to accurately determine location, especially in vertical structures like office buildings.
Innovation Solution
Employing localized access points to receive identification information from mobile devices and automatically generate responses based on their proximity, using a system that includes a receiving component, lookup component, result component, and output component to determine and send notifications or alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS components are used to detect mobile device presence, then location detection capability is provided, but device cost increases
Solution Approach 1:
The patent introduces localized access points as intermediary devices that perform location detection functions. Instead of requiring GPS components in every mobile device, the access points act as mediators that detect device presence and communicate location information to the network, thereby eliminating the need for expensive GPS hardware in consumer devices while maintaining location detection capability.
Solution Approach 2:
The patent creates a distributed network of access points that replicate location detection functionality across multiple fixed locations. Rather than embedding GPS in each mobile device, the system copies the detection capability to fixed access points throughout the environment, allowing location tracking through network infrastructure rather than device hardware.
2Measurement precision
If GPS components are used to detect mobile device presence, then location detection is enabled, but power consumption increases
Solution Approach 1:
The access points serve as powerful intermediary devices that perform the energy-intensive detection and processing functions. Mobile devices only need to communicate with the network when within range of an access point, transferring the bulk of the computational and detection burden to the fixed, power-connected access points rather than the battery-powered mobile devices.
Solution Approach 2:
The system uses periodic signaling between mobile devices and access points rather than continuous GPS operation. Location updates occur when devices enter or leave access point coverage areas, reducing power consumption by activating location functionality only when needed rather than continuously.
3Area of stationary object
If GPS systems are used for presence detection, then broad geographic area coverage is achieved, but location granularity is insufficient
Solution Approach 1:
The patent segments the broad geographic coverage area into smaller zones, each covered by individual access points. This segmentation allows the system to maintain wide area coverage through multiple access points while simultaneously providing fine-grained location information within each zone, as devices can be precisely located relative to specific access points rather than仅提供 broad GPS coordinates.
Solution Approach 2:
The system implements local quality by providing high-precision location detection within each access point coverage zone. While GPS provides uniform but coarse granularity across large areas, the access point system delivers locally optimized precise location information where devices are detected, enabling granular notifications based on specific proximity to defined locations.
Data Source
AI summary
Automatic response to localized input is provided. Where a first user equipment enters a service area, the presence of the first user equipment can be determined from an identification information. The identification information can be employed to access information relating to the identification information. Where either the identification information or the information associated with the identification information satisfy one or more predetermined rules, a response can be determined. The determined response can be made accessible. As such, a second user equipment can receive the response based, at least in part, on the first user equipment entering the service area.
