Communication Apparatus Channel Switching for Interference Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication apparatuses face challenges in efficiently switching between infrastructure connection and direct connection modes without causing radio wave interference, especially when operating in both modes concurrently.
Innovation Solution
The communication apparatus is configured to dynamically switch channels between infrastructure connection and direct connection modes using the Dynamic Rapid Channel Switching (DRCS) function, allowing it to maintain concurrent operation without interference by selecting different channels for each mode based on the frequency band set by the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the communication apparatus operates in both infrastructure connection mode and direct connection mode concurrently using the same channel, then the apparatus can maintain both connection modes, but radio wave interference occurs between the two modes
Solution Approach 1:
The communication apparatus divides the wireless communication resource by separating the channel used in infrastructure connection mode from the channel used in direct connection mode. This segmentation allows both modes to operate concurrently without interfering with each other, as each mode uses a dedicated frequency channel.
Solution Approach 2:
The apparatus applies different channel qualities (frequency channels) to different operational modes. The infrastructure connection uses one specific channel while the direct connection uses another channel, ensuring that each mode operates with optimized local characteristics without affecting the other mode's performance.
2Object-affected harmful factors
If the communication apparatus switches channels dynamically between modes, then radio wave interference is prevented, but the device complexity increases
Solution Approach 1:
The communication apparatus implements dynamic channel switching capability, allowing it to adaptively change channels based on the operational mode. This dynamic adjustment enables the apparatus to prevent radio wave interference by selecting appropriate channels for each mode while maintaining operational flexibility.
Solution Approach 2:
The apparatus employs feedback mechanisms to monitor the operational mode and automatically adjust the channel selection accordingly. When switching between infrastructure connection mode and direct connection mode, the system receives feedback about the current mode and automatically selects the appropriate channel to prevent interference.
3Stability of the object's composition
If the communication apparatus uses a fixed channel for infrastructure connection, then channel stability is maintained, but the apparatus cannot efficiently switch to direct connection mode without causing interference
Solution Approach 1:
The communication apparatus performs preliminary channel selection and preparation before mode switching occurs. By pre-configuring alternative channels and maintaining readiness for channel switching, the apparatus can transition between infrastructure connection mode and direct connection mode efficiently without causing radio wave interference.

AI summary
A specification unit is configured to, in a case where specific processing for operating a communication apparatus in a first mode is performed while the communication apparatus is operating in a second mode, specify a channel different from the channel used by the communication apparatus in the second mode during the specific processing, as a channel to be used by the communication apparatus in the second mode after the specific processing is performed, based on an agreement between a channel used by the communication apparatus in the second mode during the specific processing and a channel to be used by the communication apparatus in the first mode to be started by the specific processing.
