Dynamic Radio Mode Selection for Wireless Interference Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless computing devices operating multiple radios for concurrent connections often experience local interference, leading to degraded link quality and reduced quality of service due to simultaneous voice and data transmissions on similar frequencies.
Innovation Solution
A computing device predicts and avoids local interference by dynamically switching or consolidating radio usage, such as using a single radio for both voice and non-voice data or moving transmissions to a different radio, to minimize interference between radios operating on similar frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple radios are operated concurrently for voice and data transmissions, then connectivity and communication capabilities are improved, but local interference between radios occurs leading to degraded link quality
Solution Approach 1:
The system dynamically switches between different radio combinations based on predicted interference conditions. The radio selection is not static but adapts in real-time to avoid local interference while maintaining connectivity, allowing the device to transition between using first and second radios or consolidating to a single radio as needed
Solution Approach 2:
The system changes the operational parameters of radio usage by predicting interference based on configuration settings and scheduling information, then adjusting which radios are active. This parameter change approach allows the system to maintain multiple connectivity options while avoiding the harmful interference states
2Productivity
If multiple radios are used simultaneously, then quality of service is enhanced through diverse communication channels, but local interference reduces the overall quality of service
Solution Approach 1:
The system takes preliminary action by predicting when local interference will occur based on radio configuration settings and scheduling information before the interference actually degrades performance. This allows the system to proactively switch to a different radio combination that avoids the predicted interference, preventing the harmful effect rather than merely reacting to it
Solution Approach 2:
The interference prediction mechanism acts as an intermediary between the multiple radios and the control system. It analyzes configuration and scheduling data to identify potential interference scenarios, enabling the system to mediate radio usage by selecting optimal combinations that maintain productivity while avoiding harmful interactions

AI summary
A computing device is described for performing local interference avoidance, when supporting concurrent voice and data transmissions, and with access to multiple radios. The computing device predicts when coexistence issues will occur from maintaining independent voice and data transmissions using separate radios. To avoid local interference issues, the computing device automatically switches to operating a different combination of radios, making local interference less likely to occur. In some cases, the computing device may consolidate the voice and non-voice data exchanges to occur using a single radio. In some cases, rather than consolidation, the computing device may move the voice or the non-voice data exchange to a different radio as a way to avoid the local interference.
