Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication devices face interference issues when operating multiple radio access technologies simultaneously, such as LTE and Short Range or Metropolitan Area System technologies, due to overlapping frequency bands, leading to coexistence problems that affect signal quality and performance.
Innovation Solution
Incorporating a processor to synchronize and control the transmission and reception of signals across different transceivers, allowing for simultaneous or idle-period dependent operation of Cellular Wide Area, Short Range, and Satellite Positioning technologies, thereby mitigating interference through protocol synchronization and traffic arbitration mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple radio access technologies operate simultaneously in parallel, then connectivity versatility is improved, but interference between technologies worsens due to overlapping frequency bands
Solution Approach 1:
The patent implements time-synchronized periodic operation cycles where different radio access technologies are activated in coordinated time slots. The processor controls transceivers to transmit and receive signals in synchronized periods, creating periodic action patterns that prevent continuous interference while maintaining versatile connectivity capabilities across multiple technologies.
Solution Approach 2:
The system dynamically adjusts the operation timing of different radio access technologies based on real-time conditions. The processor monitors and controls transceiver activities, dynamically synchronizing transmission and reception periods to adapt to changing communication requirements while minimizing interference between concurrent technologies.
2Productivity
If different radio access technologies use overlapping frequency bands, then frequency resource utilization is improved, but signal quality deteriorates due to coexistence problems
Solution Approach 1:
The patent employs periodic time-synchronized operation patterns that allow different radio access technologies to share overlapping frequency bands. By coordinating transmission and reception in periodic time slots, the system maximizes frequency resource utilization while maintaining signal quality through temporal separation of concurrent operations.
Solution Approach 2:
The processor implements self-service coordination by autonomously managing the timing and synchronization of multiple transceivers. The system automatically adjusts operation periods and timing without external intervention, enabling efficient frequency resource sharing while protecting signal integrity through intelligent, self-regulated coexistence management.
