Dynamic Antenna Switching for Wireless Modems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication apparatuses with fixed corresponding relations between modems and antennas suffer from deteriorated information transceiving capability when the quality of one antenna's signal reduces, limiting overall device performance.
Innovation Solution
A wireless communication apparatus with a switch that allows antennas to be dynamically switched between modems based on the quality of received radio-frequency signals, using control signals generated by the modems to determine and improve communication quality by selecting the best antenna for signal processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed corresponding relation between modems and antennas is used, then the device structure is simple, but the information transceiving capability deteriorates when antenna signal quality reduces
Solution Approach 1:
The patent implements dynamic antenna switching where the correspondence between modems and antennas changes based on real-time signal quality conditions. The switch dynamically reconfigures connections based on quality determination, transforming the static fixed correspondence into a dynamic adaptive system that responds to changing environmental conditions.
Solution Approach 2:
The system incorporates feedback mechanisms where signal quality information is continuously monitored and fed back to the control logic. The quality determination unit evaluates antenna signal quality and feeds this information back to the switch, which then adjusts the modem-antenna correspondence accordingly, creating a closed-loop control system that improves reliability through adaptive response.
2Reliability
If signal quality monitoring and switching control are added, then communication quality improves, but the device complexity increases
Solution Approach 1:
The switch serves multiple functions: it acts as a signal routing component, a quality-based decision execution unit, and a reconfigurable connection manager. By making the switch multi-functional, the patent reduces the need for separate dedicated components for each function, thereby improving communication quality while minimizing the increase in device complexity.
Solution Approach 2:
The system implements self-service through automatic quality monitoring and autonomous switching decisions. The quality determination unit automatically evaluates signal conditions and the switch autonomously reconfigures connections without requiring external intervention or complex control mechanisms, allowing the system to improve its own performance through self-managed adaptation.
