Dual-Mode Wireless Device for Stable Roaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless Internet systems face challenges in providing reliable, fast, and secure connections for roaming devices, particularly in unmanaged networks, where handovers between WiFi access points are slow, resources are often exhausted, and configuration is complex, leading to poor coverage and security concerns.
Innovation Solution
A system that allows devices to function as both stations and access points, enabling simultaneous connections to multiple access points for improved stability and bandwidth, with a software solution that facilitates easy configuration and secure access, while reducing location updates and resource exhaustion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices function as both stations and access points with simultaneous connections to multiple access points, then connection stability and bandwidth are improved, but device complexity and power consumption increase
Solution Approach 1:
The patent implements dual-mode wireless communication capability where a single device can operate as both a station (STA) and an access point (AP) simultaneously. The wireless communication unit is configured to support multiple operational modes, allowing the device to connect to networks as a client while also providing access point functionality for other devices. This multi-functionality resolves the contradiction by enabling connection stability through multiple AP connections while using a unified device architecture rather than adding separate hardware components.
2Area of stationary object
If handover between WiFi access points is performed in unmanaged networks, then network coverage is extended, but handover latency increases
Solution Approach 1:
The patent implements connection establishment procedures that occur in advance of actual data transmission needs. When a station moves into the coverage area of a new access point, the connection is pre-established including authentication, association, and IP address allocation before the station actually needs to communicate through that AP. This preliminary action eliminates handover latency by ensuring the connection is ready before it is needed, while still extending network coverage through seamless transitions between access points.
3Reliability
If access points are locked for security reasons, then network security is improved, but accessibility for roaming devices deteriorates
Solution Approach 1:
The patent introduces a credential distribution mechanism that acts as an intermediary between locked access points and roaming devices. Instead of requiring direct authentication between each device and every access point, the system uses pre-distributed credentials and a centralized authentication framework that allows devices to access locked networks without compromising security. The intermediary layer verifies credentials and manages access rights, maintaining security while enabling broad accessibility for authorized roaming devices.
4Productivity
If software solutions are deployed in access points to enable pay-for-use functionality, then revenue generation is improved, but ease of deployment and configuration deteriorates
Solution Approach 1:
The patent implements automated software deployment and configuration mechanisms where access points automatically download, install, and configure billing and authentication software without requiring manual intervention. The system uses self-provisioning capabilities where devices automatically register with billing servers, receive appropriate credentials, and configure their own payment and access parameters. This self-service approach enables revenue generation through pay-for-use functionality while eliminating the complexity of manual software deployment and configuration.
Data Source
AI summary
A method, system, and apparatus, including a program encoded on computer-readable medium, for transmitting data to a server. A wireless communication connection is established between a first computing device and a second computing device. Data transmitted from the first computing device to the second computing device is received over the wireless communication connection and stored on the second computing device for uploading to a server on an IP based network. The wireless communication connection is disconnected. An IP communication connection is established between the second computing device and the server on the IP based network, and at least a portion of the stored data is transmitted from the second computing device to the server on the IP based network over the IP communication connection after the wireless communication connection between the first computing device and the second computing device is disconnected.
