Virtual Geographic Zones Using Polygonal Coordinates

The patent segments the geographic zone definition from the network infrastructure. Instead of relying on network coverage areas (cell towers, Wi-Fi ranges) to define zones, the system divides zones into discrete polygonal regions with precisely defined vertices and edges. Each zone is independently defined by coordinate data that can be stored and processed separately from the network infrastructure, allowing accurate representation of complex building shapes and interiors.

The patent introduces a database as an intermediary between the network infrastructure and the geographic zone definition. The database stores precise polygonal zone definitions with vertex coordinates, acting as a mediator that decouples the network's coverage area from the zone's geometric definition. This allows the system to use network infrastructure for communication while maintaining independent, precise zone boundaries that can conform to any shape.

The patent implements preliminary action by pre-defining zones as polygonal regions with stored vertex coordinate data before deployment. Administrators can create, store, and manage zone definitions in advance using the database system. This pre-definition allows zones to be precisely customized to match specific building layouts, floors, and rooms, while the system maintains ease of implementation through automated coordinate processing and zone management.

The patent adds a geometric dimension to zone definition by using polygonal coordinates (x, y, z vertices) rather than relying on network infrastructure geometry. This dimensional approach allows zones to be defined in three-dimensional space, enabling customization for multi-story buildings, specific floors, and complex architectural layouts while maintaining systematic implementation through coordinate-based storage and processing.

The patent replaces the signal-based mechanical system with a mathematical coordinate system. Instead of using signal strength, propagation, or physical presence to define zone boundaries, the system uses precisely calculated vertex coordinates and geometric equations. This substitution eliminates signal interference, attenuation, and boundary fuzziness, providing reliable and exact zone definitions that can be verified through coordinate comparison rather than signal detection.

The patent fundamentally changes the parameter used to define zone boundaries from signal-based parameters (signal strength, coverage range) to geometric parameters (vertex coordinates, polygon equations). This parameter change transforms zone definition from an analog, fuzzy process to a digital, precise process. The system stores zone boundaries as sets of coordinates and uses mathematical comparisons to determine zone engagement, eliminating all issues related to signal interference and boundary indistinctness.
