Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interference between adjacent frequency bands in communication services leads to reduced signal quality, affecting services like Car-to-X, V2X, WLAN, aircraft radar, and mobile communications, due to increasing electromagnetic spectrum usage.
Innovation Solution
A method where a mobile transmission unit generates a list of positions for fixed installations of adjacent communication services, adjusts its transmission characteristics based on proximity to these installations, and uses existing sensors or receivers for triangulation, allowing for reduced interference by modifying transmission power or radiation patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple communication services operate in adjacent frequency bands, then the electromagnetic spectrum utilization is improved, but interference between services increases and signal quality deteriorates
Solution Approach 1:
The patent implements dynamic adaptation of transmission characteristics by continuously monitoring the position of mobile transmitting units and adjusting transmission power or radiation patterns in real-time based on proximity to fixed installations of other communication services. This dynamic approach allows the system to maintain high spectrum utilization while adaptively reducing interference when services operate in close proximity.
Solution Approach 2:
The patent applies local quality by making transmission characteristics spatially variable - different transmission parameters (power, antenna orientation, beamforming patterns) are used in different geographic locations. When a mobile unit approaches a fixed installation of another communication service, the transmission characteristics are locally adapted to minimize interference in that specific area while maintaining normal operation elsewhere.
2Reliability
If transmission power is increased to improve communication quality, then signal strength is improved, but interference with adjacent frequency bands increases
Solution Approach 1:
The patent changes transmission parameters (power level, antenna orientation, beamforming characteristics) based on the spatial relationship between mobile transmitting units and fixed installations of other communication services. By dynamically adjusting these parameters according to position and proximity, the system maintains reliable signal quality when needed while reducing interference parameters when operating near other services.
Solution Approach 2:
The system continuously monitors position data and dynamically adjusts transmission characteristics in real-time. This dynamic adaptation allows transmission power to be optimized for signal quality when interference risk is low, while automatically reducing power or modifying radiation patterns when proximity to other communication services is detected.
3Measurement precision
If additional sensors or hardware are added to detect fixed installations, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent makes existing multi-functional components serve additional purposes. Sensors originally designed for navigation or other communication functions are repurposed to detect fixed installations of other communication services. This universal approach allows the system to achieve accurate detection without adding dedicated hardware, as existing sensors can serve multiple detection functions.
Solution Approach 2:
The system uses its own existing sensors and receivers to detect fixed installations of other communication services, rather than requiring separate dedicated detection hardware. The mobile transmitting unit leverages its inherent sensing capabilities and available position information to perform interference detection and avoidance functions.
