Spectrum Management System for RPV Channel Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spectrum management systems for wireless communication systems in geographical proximity, such as remotely piloted vehicle (RPV) systems, face challenges in allocating frequencies to prevent channel interference, particularly from non-player spectators and other games, and do not allow systems to switch channels efficiently without authorization.
Innovation Solution
A spectrum management system that allocates a set of frequencies to each RPV system, allowing them to select channels based on conditions, with power level limits to prevent interference, and includes a central manager and local managers for real-time channel and power adjustments to mitigate interference from various sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single frequency is allocated to each RPV system, then the spectrum management is simple, but channel interference occurs when multiple systems operate in geographical proximity
Solution Approach 1:
The patent segments the frequency pool into multiple frequency sets, where each RPV system is allocated a specific set containing multiple frequencies. This segmentation allows systems to select from multiple options within their allocated set, reducing interference while maintaining manageable complexity through structured organization.
Solution Approach 2:
The patent introduces a new dimension to frequency allocation by providing each system with a set of multiple frequencies rather than a single frequency. This dimensional change from scalar to vector allocation enables systems to navigate frequency space more effectively, selecting optimal frequencies dynamically to avoid interference.
2Adaptability or versatility
If multiple frequencies are allocated to each RPV system, then channel selection flexibility increases, but spectrum management complexity increases
Solution Approach 1:
The spectrum manager performs preliminary action by pre-allocating multiple frequency sets to each RPV system before operation begins. This preliminary organization of frequency resources provides systems with ready-to-use options, enabling flexible channel selection without requiring complex real-time management decisions during operation.
Solution Approach 2:
The spectrum manager acts as an intermediary that handles the complexity of frequency allocation centrally. By concentrating management functions in the spectrum manager rather than distributing complexity to each RPV system, the patent achieves high adaptability for individual systems while keeping overall management complexity centralized and controllable.
3Speed
If RPV systems switch channels autonomously, then response time to interference is reduced, but unauthorized channel switching may cause new interference
Solution Approach 1:
The patent applies local quality by giving each RPV system autonomous authority to select frequencies within its specifically allocated set. This localized decision-making enables fast response to interference conditions without requiring centralized authorization for each switch, while the pre-defined frequency sets ensure that autonomous choices remain within acceptable parameters and do not create unauthorized interference.
4Reliability
If power levels are increased to maintain communication quality, then communication reliability improves, but interference to other systems increases
Solution Approach 1:
The patent utilizes parameter changes by dynamically adjusting power levels based on selected frequency and interference conditions. Rather than maintaining constant high power, the system adapts power parameters to achieve necessary communication reliability at the minimum required level, thereby reducing harmful interference to other systems while maintaining adequate communication quality.

AI summary
A spectrum management system to allocate frequencies in a plurality of wireless communication systems in geographical proximity includes a spectrum manager to allocate a pool of frequencies among the wireless communication systems. Each system is allocated a set of frequencies for selecting on which frequency to operate with at least one of the sets of frequencies including more than one frequency, and at least two of the allocated sets different from each other. The system additionally includes a database to store and organize information used by the spectrum manager to perform the allocation.
