Wireless Signal Area Control via Direction and Power Records
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems cannot effectively limit the transmission of wireless signals within a specific area, as they rely on user position verification rather than directional and power control, making it difficult to ensure signal access is restricted to authorized areas.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user position verification is used to limit wireless signal access, then security management is improved, but the wireless signal transmission cannot be effectively limited within the permission area
Solution Approach 1:
The patent applies local quality by controlling wireless signal transmission parameters (direction and power) specifically for different spatial locations. The system divides the coverage area into permission areas and non-permission areas, and applies different transmission characteristics to signals directed toward different locations, thereby achieving location-based access control without requiring complex position verification protocols.
Solution Approach 2:
The patent changes transmission parameters (direction and power) dynamically based on the intended reception location. By adjusting the beam direction and transmission power levels according to whether a location falls within the permission area, the system effectively limits signal transmission to authorized zones without needing to verify user positions through complex authentication mechanisms.
2Reliability
If directional control and power adjustment are implemented to limit signal transmission, then signal access restriction is improved, but device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-calculating and storing the mapping relationships between reference positions, point directions, and power levels before actual operation. The determination module uses these pre-computed data structures to quickly decide transmission parameters during runtime, avoiding complex real-time calculations and reducing the operational complexity of the control system.
Solution Approach 2:
The patent introduces an intermediary determination module that acts as a mediator between the permission area definition and the actual transmission control. This module pre-processes the permission area information and creates lookup tables mapping reference positions to transmission parameters, thereby simplifying the control logic and reducing the complexity of the transmission control system.
3Adaptability or versatility
If reference positions are used to define permission areas, then area definition flexibility is improved, but the system cannot ensure users only receive signals in authorized areas
Solution Approach 1:
The patent applies local quality by associating specific transmission characteristics with specific spatial locations defined by reference positions. Each reference position has pre-determined point direction and power information, creating location-specific transmission profiles. This ensures that signals are transmitted with appropriate characteristics only toward authorized locations, providing both flexibility in area definition and reliability in signal reception assurance.
Solution Approach 2:
The patent implements feedback by using the pre-stored point direction and power information records as a form of lookup feedback. When a transmission is requested, the system queries the determination module which retrieves the appropriate transmission parameters based on the target location relative to reference positions, ensuring that the transmitted signal matches the authorized parameters for that specific area.
