Wi-Fi Direct Parameter Exchange with Frequency-Based WPA3 Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies, such as Wi-Fi Direct, face challenges in efficiently setting communication parameters, particularly for high-frequency bands like 6 GHz, where authentication methods like WPA3 are required, and existing methods like WPS and WEC are not optimized for seamless parameter exchange.
Innovation Solution
A communication apparatus equipped with an acquisition unit to determine the frequency for Wi-Fi Direct communication and a providing unit to exchange communication parameters using Wi-Fi Easy Connect (WEC) for WPA3 authentication, or Wi-Fi Protected Setup (WPS) for WPA2, ensuring seamless network formation across different frequency bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Wi-Fi Protected Setup (WPS) is used for parameter exchange, then ease of operation is improved, but reliability deteriorates for 6 GHz frequency band communication
Solution Approach 1:
The patent dynamically selects between WPS and WEC authentication methods based on the frequency band. For 2.4 GHz and 5 GHz bands, WPS is used for ease of operation. For 6 GHz band, WEC is automatically selected to ensure reliability and security, as WPS is not supported or reliable in the 6 GHz band.
Solution Approach 2:
The patent changes the authentication parameter (method selection) based on the frequency band parameter. When the frequency is detected as 6 GHz, the system switches from WPS parameter set to WEC parameter set, ensuring appropriate authentication method is applied for each frequency band.
2Reliability
If Wi-Fi Easy Connect (WEC) is used for parameter exchange, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies different authentication qualities to different frequency bands. WEC with enhanced security is applied locally to the 6 GHz band where it is most needed, while maintaining simpler WPS operation for 2.4 GHz and 5 GHz bands where ease of operation is prioritized.
3Adaptability or versatility
If frequency band is expanded to include 6 GHz, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal authentication selection mechanism that handles multiple frequency bands (2.4 GHz, 5 GHz, 6 GHz) through a single decision framework. The system automatically detects the frequency band and selects the appropriate authentication method, providing multi-frequency adaptability without requiring separate complex handling for each band.
