Electronic Device Access Point Selection Data Traffic Rate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless networks, devices often connect to access points with higher signal strength but lower data traffic rates, leading to suboptimal data services.
Innovation Solution
An electronic device scans access points with the same SSID, calculates data traffic rates based on beacon frames, and selects the access point with the highest data traffic rate for connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device connects to the access point with higher signal strength, then the connection stability is improved, but the data traffic rate deteriorates
Solution Approach 1:
The patent changes the selection parameter from signal strength alone to a composite criterion that includes both signal strength and data traffic rate. The processor calculates the data traffic rate based on beacon frame information and uses this additional parameter to make the AP selection, thereby resolving the contradiction between connection stability and data traffic rate.
2Ease of operation
If the electronic device selects access point based on signal strength only, then the selection process is simple, but the data service quality deteriorates
Solution Approach 1:
The system automatically calculates the data traffic rate using beacon frame information and performs the optimized AP selection without user intervention. The processor extracts relevant parameters from beacon frames, computes the data traffic rate, and autonomously selects the optimal AP, maintaining ease of operation while improving data service quality.
3Productivity
If the electronic device calculates data traffic rate for each access point, then the data service quality is improved, but the processing complexity increases
Solution Approach 1:
The patent performs preliminary extraction of necessary information from beacon frames before the actual AP selection process. By pre-calculating the data traffic rate using already-available beacon frame parameters (such as basic rate and extended rate information), the system avoids complex real-time calculations during the selection moment, thus reducing processing complexity while maintaining data service quality.
