Dedicated-and-Dynamic Virtual Access Point for Network Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless local area networks (WLANs) with independent access points (APs) experience degraded user experience due to lengthy authentication and association processes, and poor management leads to suboptimal performance, especially in high-density scenarios.
Innovation Solution
Implementing a Dedicated-and-Dynamic Virtual Access Point (DD-VAP) system, where a server customizes and configures a DD-VAP on a Physical Access Point (PAP) for each station, optimizing network access by adjusting transmission profiles and reducing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If independent APs are manually managed with traditional authentication processes, then device complexity is reduced, but network access time increases significantly
Solution Approach 1:
The system performs preliminary actions by pre-establishing service profiles and VAP configurations on the server before stations need network access. When a station probes for network, the server has already prepared customized VAP settings, eliminating the need for lengthy traditional authentication and association processes.
Solution Approach 2:
The server acts as an intermediary between stations and APs, managing VAP creation and configuration centrally. This intermediary approach automates the complex authentication and association processes, reducing both user-perceived access time and operational complexity through centralized control.
2Adaptability or versatility
If high-density APs are distributed for ubiquitous network access, then network coverage is improved, but overall network performance deteriorates due to poor management
Solution Approach 1:
The server provides universal management capabilities across all APs in the network, implementing a unified VAP management system that works consistently regardless of AP density or location. This multi-functional approach allows centralized control over channel allocation, power settings, and service profiles across the entire network infrastructure.
Solution Approach 2:
The system dynamically adjusts VAP configurations based on real-time network conditions, station requirements, and AP capabilities. The server continuously optimizes channel assignments, transmission power, and service profiles for each VAP, enabling the network to adapt to changing conditions and maintain high performance even in high-density deployments.
3Ease of operation
If traditional public VAPs are used for network access, then ease of operation is improved, but network optimization and customization capability deteriorates
Solution Approach 1:
The system segments the network into multiple virtual access points (VAPs) with distinct service profiles, allowing different customization levels for different stations or station groups. Each VAP can have optimized parameters for specific applications or user types, while maintaining simple access procedures through automatic VAP selection based on station profiles.

AI summary
A wireless communication method comprises the following steps: a Static and Public Virtual Access Point (PS-VAP) on a Physical Access Point (PAP) receives a Probe Request from a station; the PS-VAP sends a Virtual Access Point (VAP) Setup Request to a server in response to the Probe Request; the PAP creates a Dedicated-and-Dynamic VAP (DD-VAP) having a Service Set Identifier (SSID) for the station according to a VAP Setup Response sent from the server; and the DD-VAP sends a Probe Reply including the SSID of the DD-VAP to the station.
