Dynamic QR Code Frequency Channel Sharing for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices connected to a wireless network may fail to communicate effectively with other devices providing information about a frequency channel due to differences in used frequency channels, especially when the providing device is already connected to another network.
Innovation Solution
A communication apparatus with a determination unit to check network connection, a generation unit to create images with frequency channel information, and a communication unit to facilitate communication using the generated images, ensuring that the frequency channel information is accurately shared and used for communication, whether the device is connected or not.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the apparatus presents a QR code with frequency channel information for easy connection, then communication setup becomes simpler, but communication fails when the apparatus is already connected to a different wireless network
Solution Approach 1:
The patent applies dynamics by making the frequency channel information in the QR code dynamic rather than static. The system detects whether the apparatus is currently connected to a wireless network and automatically updates the QR code to reflect the current operational frequency channel. This ensures the QR code always contains accurate, real-time frequency information that matches the apparatus's actual communication state, resolving the contradiction between ease of connection and connection reliability.
2Device complexity
If the apparatus uses a fixed frequency channel in the QR code, then the QR code structure remains simple, but the apparatus cannot communicate with devices on different networks
Solution Approach 1:
The patent applies parameter changes by modifying the frequency channel parameter in the QR code based on the apparatus's network connection state. Instead of using a fixed frequency channel, the system changes the frequency parameter dynamically to match the current network environment. This allows the QR code to adapt to different networks while maintaining its basic structure, thus resolving the contradiction between structural simplicity and network compatibility.

AI summary
A communication apparatus includes a generation unit that generates an image including information about a frequency channel used for executing wireless communication and a communication unit that communicates with another communication apparatus that has read the generated image using the frequency channel included in the image. When the communication apparatus is connected to the wireless network, an image including information about a frequency channel used for the connected wireless network is generated, and when the communication apparatus is not connected to the wireless network, an image including information about a predetermined frequency channel is generated.
