Beacon-Based Wi-Fi Credential Delivery for Device Reassociation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices in a network may lack updated access credentials or fail to receive them due to factory resets or other issues, leading to difficulties in initial network association or reassociation, especially in environments where credentials are updated frequently.
Innovation Solution
A system where a first device broadcasts network credentials in a beacon message, allowing a second device to receive and access a second Wi-Fi network using these credentials, facilitating network association without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network credentials are updated frequently to maintain security, then network security is improved, but devices may fail to receive updated credentials and remain disconnected
Solution Approach 1:
The system performs preliminary action by embedding credentials in beacon frames in advance, so that when devices need to connect or reconnect, the credentials are already available in the broadcast environment. This eliminates the need for separate credential distribution steps and ensures devices receive updated credentials automatically when they broadcast their connection requests.
2Ease of operation
If devices perform factory reset to resolve connection issues, then device functionality is restored, but devices lose network credentials and require manual reconfiguration
Solution Approach 1:
The system enables self-service by allowing devices to automatically obtain credentials from beacon frames without human intervention. When a device performs factory reset or needs to reconnect, it simply broadcasts a connection request and receives the necessary credentials automatically from the environment, eliminating manual configuration steps and reducing reassociation time.
3Reliability
If manual credential distribution is used to ensure accurate delivery, then credential delivery reliability is improved, but the complexity of the association process increases
Solution Approach 1:
The system uses beacon frames as an intermediary mechanism to transfer credentials. Instead of direct device-to-device or device-to-server credential distribution, credentials are embedded in beacon frames that are naturally broadcast in the environment. Devices intercept these beacon frames to obtain credentials, simplifying the overall process while maintaining reliable delivery.
4Adaptability or versatility
If beacon frames are used to broadcast credentials to all devices, then credential distribution coverage is improved, but network security may be compromised by unauthorized access
Solution Approach 1:
The system applies local quality by making beacon frames with credentials visible only to devices that are physically or logically in the appropriate location or context. Credentials embedded in beacon frames are intended for specific networks and locations, so only devices that should have access can successfully authenticate and join the network, while others ignore the beacons or fail authentication.
Data Source
AI summary
Systems and methods for beacon-based network management are disclosed. A first device is configured to transmit a broadcast message indicating a presence of a first network. The broadcast message can include credentials for a second network. A second device is configured to receive the broadcast message, retrieve the credentials for the second network, and access, via provision of the credentials to a third device, the second network.
