Automatic Wireless LAN Pairing via MAC Address Credential Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for pairing devices with wireless LANs, such as Wi-Fi networks, are cumbersome, especially for large or immobile devices and those with restricted mobility, as they require manual entry of passwords or precise button presses within a short time frame, which can be impractical.
Innovation Solution
A method and device that automatically pair with a wireless LAN by using stored security credentials to establish a connection and securely transfer necessary credentials from an available access point, allowing for seamless integration without user intervention beyond powering on the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual password entry is required for device pairing, then security credentials can be securely transferred, but the pairing process becomes cumbersome and time-consuming
Solution Approach 1:
The access point stores the Wi-Fi password in advance and automatically provides it to new devices through the web portal, eliminating the need for manual password entry by the user. The password is prepared beforehand and delivered automatically when a device connects.
Solution Approach 2:
A web portal acts as an intermediary between the access point and the device. The web portal captures the device's MAC address, retrieves the corresponding password from the access point's stored credentials, and automatically transfers it to the device, eliminating direct manual password entry.
2Ease of operation
If WPS button pressing is used for pairing, then password entry is avoided, but precise timing within two minutes is required which is impractical for immobile devices
Solution Approach 1:
The system performs the pairing operation automatically without requiring user action. The device automatically connects to the access point's web portal, and the access point automatically provides the password based on the device's MAC address, eliminating the need for coordinated button pressing within a time window.
Solution Approach 2:
The mechanical button-pressing mechanism is replaced with an automated electronic process. Instead of requiring physical button presses within a time window, the system uses automatic MAC address recognition and credential delivery through the web portal, removing the time constraint entirely.
3Reliability
If complex passwords are used for security, then network security is improved, but the likelihood of mis-keying increases
Solution Approach 1:
Instead of requiring the user to manually type the complex password, the system automatically copies the password from the access point's stored credentials to the device. The exact password string is transferred without human intervention, eliminating transcription errors while maintaining security.
Solution Approach 2:
The web portal serves as an intermediary that handles the complex password transfer automatically. It retrieves the exact password string from the access point and delivers it to the device without requiring the user to see or type it, ensuring accurate transmission of complex credentials.

AI summary
A method for the automatic pairing of a device (401) wirelessly with a user's secure WLAN provided by an access point (403), the pairing access point (403), that provides the secure wireless LAN and a second wireless LAN (e.g. a public Wi-Fi hotspot). A connection is established automatically between the device (401) and a wireless LAN provided by an available access point (410) using security credentials stored on the device (401). If it is determined that the available access point (410) is also the pairing access point (403), using the established connection to securely transfer second security credentials from the available access point (410) to the device (401). The transferred second security credentials can then be used to establish a secure connection between the device (401) and the first secure wireless LAN provided by the pairing access point (403).
