Dynamic Wireless Spectrum Allocation for Industrial Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial environments face challenges with wireless network radio frequency spectrum congestion and co-channel interference due to the coexistence of domestic and foreign network devices, which existing methods partially address by segregating frequency channels or reducing transmission power, but these solutions reduce overall wireless spectrum coverage.
Innovation Solution
A system utilizing real-time location tracking tags and devices, along with a control unit, dynamically modifies network configurations of domestic network devices based on proximity policies when foreign network devices enter the area, ensuring minimal interference while maintaining full spectrum availability to local devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If frequency channels are segregated or transmission power is reduced to mitigate interference between domestic and foreign network devices, then interference is reduced, but wireless spectrum coverage area is reduced
Solution Approach 1:
The patent applies dynamics by transitioning from static frequency channel segregation and permanent power reduction to dynamic, real-time spectrum allocation. The system continuously monitors foreign device locations and dynamically adjusts domestic device configurations only when needed, allowing full spectrum availability when foreign devices are absent while preventing interference when they are present. This resolves the contradiction by making the interference mitigation measure temporary and location-based rather than permanent and blanket-applied.
Solution Approach 2:
The patent implements local quality by applying interference mitigation measures only in specific locations where foreign devices are detected, rather than uniformly across the entire network. The control unit modifies domestic device configurations locally in proximity to foreign devices while maintaining full spectrum coverage in areas without foreign devices. This allows the system to reduce interference where necessary while preserving wireless spectrum coverage area where it is not needed.
2Adaptability or versatility
If real-time location tracking and dynamic configuration modification are implemented, then spectrum utilization is optimized, but system complexity increases
Solution Approach 1:
The patent applies self-service by enabling the system to automatically detect foreign device locations, determine interference conditions, and modify domestic device configurations without human intervention. The control unit autonomously queries proximity policies, applies modified configurations when foreign devices are detected, and restores default configurations when they are not present. This automation resolves the contradiction by making the system self-managing, where the complexity is encapsulated in automated processes rather than requiring continuous manual management.
Solution Approach 2:
The patent implements feedback by continuously monitoring foreign device locations through real-time location tracking and using this information to dynamically adjust domestic device configurations. The system receives feedback from location tracking about foreign device presence and responds by modifying or restoring configurations accordingly. This feedback loop enables optimized spectrum utilization while managing complexity through automated response to changing conditions.

AI summary
A system for allocating wireless frequency spectrum is provided. The system may include one or more location tags attached on one or more foreign network devices and domestic network devices, one or more real-time location tracking system configured to detect the one or more location tags, and at least one control unit in communication with at least one domestic network device. The control unit may be configured to query one or more proximity policies associated with the foreign network devices and the domestic network devices, apply a modified network configuration to one or more of the domestic network devices when at least one associated proximity policy is discovered, and restore a default network configuration, or setting the modified network configuration as a new default network configuration, to the one or more of the domestic network devices when the discovered proximity policy is no longer effective.
