Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spectrum management systems fail to provide real-time or near real-time assessment and prediction of RF interference, leading to inefficient utilization of shared spectrum resources among wireless devices, as they primarily rely on static bandwidth allocation without considering time and bandwidth space management.
Innovation Solution
A server and database system that collects and stores interference information from multiple devices to identify non-interfering bandwidths, allowing for real-time allocation of bandwidth based on stored indications, thereby enabling efficient spectrum management and utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static bandwidth allocation is used, then device complexity is reduced, but spectrum utilization efficiency deteriorates
Solution Approach 1:
The patent implements dynamic spectrum allocation by transitioning from static bandwidth assignment to real-time adaptive allocation. The system continuously monitors RF interference conditions and dynamically adjusts bandwidth assignments based on current spectral environment, device locations, and interference patterns, thereby optimizing spectrum utilization without requiring overly complex centralized control
Solution Approach 2:
The patent enables devices to autonomously perform spectrum sensing and interference detection. Each device can independently identify available bandwidths and negotiate allocations with other devices, reducing the complexity of centralized management while improving overall spectrum efficiency through distributed intelligence
2Productivity
If real-time interference assessment is implemented, then spectrum utilization efficiency is improved, but measurement precision requirements increase
Solution Approach 1:
The patent applies partial measurement by focusing RF sensing on specific frequency bands and time periods relevant to current communications needs. Rather than continuously monitoring the entire spectrum with high precision, the system performs targeted measurements only where and when interference is likely to impact active transmissions, reducing the overall measurement precision burden while maintaining effective interference assessment
Solution Approach 2:
The patent implements predictive interference assessment by analyzing historical interference patterns and device movement trends to forecast future interference conditions. This preliminary action allows the system to proactively allocate bandwidth before interference occurs, reducing the need for high-precision real-time measurement while maintaining high spectrum utilization efficiency
3Reliability
If centralized spectrum management is used, then interference coordination is improved, but device complexity increases
Solution Approach 1:
The patent divides the centralized spectrum management function into distributed segments performed by individual devices through local RF sensing and interference detection. Each device independently manages its own spectrum allocations and coordinates with nearby devices through simplified protocols, achieving effective interference coordination without requiring a complex centralized management infrastructure

AI summary
A spectrum management database and server provides measurement and modeling of RF (Radio Frequency) cloud interference in near real-time results for efficient utilization of the precious spectrum. This shared spectrum defines a scarce resource shared among all wireless devices of the universe in frequency, time, and space. Near real-time forecasting of the RF cloud interference is beneficial in pursuit of a path to the optimal utilization of spectrum and a liberated spectrum management. A spectrum management server gathers interference information including bandwidth ranges and locations from a plurality of deployed devices, receives requests for bandwidth, and satisfies the request by allocating a non-interfering bandwidth at a requesting location based on the stored indications
