Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional WLAN systems face challenges in real-time responsiveness and accuracy in selecting optimal antenna groups and transmission rates due to poor real-time capability and low accuracy in antenna scan processes, leading to suboptimal transmission performance.
Innovation Solution
A method that combines antenna group selection with real-time transmission rate adjustment using timers and statistical data analysis to dynamically switch between antenna groups and adjust transmission rates, eliminating the need for a fixed probe period and improving the efficiency of parameter selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed probe period is used for antenna scanning, then the system can perform periodic antenna group selection, but the real-time responsiveness deteriorates and the system cannot adapt to rapid wireless environment changes
Solution Approach 1:
The patent transforms the static fixed probe period into a dynamic mechanism where the scanning process is triggered by real-time events (data transmission failures, channel changes, or periodic intervals). The system dynamically adjusts the scanning frequency based on current network conditions, allowing faster response to environmental changes while maintaining accurate antenna group selection through continuous performance monitoring and adaptive reconfiguration.
2Productivity
If conventional antenna scanning methods are used, then the system can identify antenna groups, but the selection accuracy deteriorates due to lack of real-time adjustment
Solution Approach 1:
The patent implements a feedback mechanism where the access point continuously monitors transmission performance metrics (signal strength, error rates, throughput) and uses this information to evaluate antenna group performance. The system compares current antenna group performance against historical data and automatically adjusts selections based on real-time feedback, significantly improving both the accuracy and efficiency of parameter selection by eliminating guesswork and relying on measured performance data.
3Reliability
If multiple antenna groups are scanned periodically, then the system can find optimal antennas, but the resource consumption increases and real-time capability decreases
Solution Approach 1:
The patent applies partial action by scanning only the necessary subset of antenna groups based on current network conditions and historical performance data. Instead of periodically scanning all antenna groups regardless of usage patterns, the system identifies and scans only the most promising antenna groups according to real-time transmission success rates and signal quality metrics, reducing unnecessary resource consumption while maintaining reliable transmission performance through targeted optimization.

AI summary
A method for data transmission disclosed is applied to an access point for use in a wireless local area network. The access point has multiple antennas. The method comprises in response to transmitting a first message successfully to a station, determining a maximum transmitting rate at which a message can be transmitted successfully using a current antenna group by increasing the transmitting rate and transmitting a message repeatedly; and, transmitting further messages to the station at the determined maximum transmitting rate.
