Pay-Per-Connection Wi-Fi Access Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hotspot business models are costly, complex, and inefficient due to large-scale operations, overlapping Wi-Fi services, inadequate seamless handoff, and unnecessary AAA architecture, which are not tailored to Wi-Fi technology's characteristics and usage patterns.
Innovation Solution
A pay-per-connection (PPC) system that allows users to access Wi-Fi networks without subscription, using a device that requires payment and a passcode for connection, enabling small businesses to provide hotspot services with a low-cost, site-specific model, employing MAC address filtering and per-user encryption to manage access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a centralized subscription model with large-scale deployment is used, then customers can access multiple hotspots and roaming services are provided, but the business setup cost and operational complexity increase significantly
Solution Approach 1:
The patent divides the centralized AAA system into distributed authentication components at each hotspot. Each hotspot independently handles authentication using local credentials (credit cards, coupons, tokens), eliminating the need for a centralized subscription management infrastructure while maintaining multi-hotspot access capability.
Solution Approach 2:
The system enables hotspots to autonomously authenticate users through locally stored credential verification mechanisms. Each hotspot can independently validate user credentials and grant access without querying a central server, reducing system complexity while preserving roaming functionality.
2Adaptability or versatility
If multiple service providers deploy hotspots in the same area, then service coverage is expanded, but Wi-Fi channel congestion worsens due to limited bandwidth
Solution Approach 1:
The patent implements location-specific credential validation where each hotspot verifies user credentials locally rather than through centralized authentication. This distributed approach allows multiple providers to coexist in the same area without requiring coordination, as each hotspot independently manages its own authentication and bandwidth allocation.
3Adaptability or versatility
If a centralized AAA architecture is implemented, then roaming and seamless handoff are enabled, but the system becomes costly and unnecessary for typical hotspot usage patterns
Solution Approach 1:
The patent extracts the authentication function from the centralized AAA architecture and implements it as a standalone local credential verification mechanism at each hotspot. This removes the complex accounting and authorization components while retaining the essential authentication capability needed for roaming.
Solution Approach 2:
The system uses disposable credentials (single-use tokens, time-limited coupons, expiring credit card authorizations) that can be validated locally without requiring persistent centralized database connections. This eliminates the need for complex AAA infrastructure while enabling roaming through simple local verification.

AI summary
A pay-per-connection system is coupled to a network service provider and to a client computer. The pay-per-connection system receives payment and a passcode from a user, determines duration of use based on the payment, and provides access by the client computer to the network service provider based on the payment and the passcode without advance sign-up by the user with the network service provider.
