Wi-Fi Aggregation Control for Low-Latency Packet Flows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data aggregation in wireless networks can inadvertently add latency for low-latency applications, such as gaming, by consolidating multiple packets into single units before transmission, which is detrimental to seamless user experiences.
Innovation Solution
Dynamically enabling and disabling data aggregation control based on the identification of low-latency applications, allowing devices to communicate this information to Wi-Fi drivers to adjust aggregation settings during connection setup and negotiation, and enabling/disabling aggregation as needed to optimize network efficiency.

Engineering Contradiction Analysis
1Productivity
If data aggregation is enabled to improve network efficiency, then network throughput is improved, but latency increases for low-latency applications
Solution Approach 1:
The patent implements dynamic aggregation control where the aggregation state (enabled/disabled) is adjusted in real-time based on application requirements. The system transitions from a static aggregation configuration to a dynamic one that adapts to different application needs, enabling aggregation for throughput-intensive applications while disabling it for low-latency applications.
Solution Approach 2:
The patent applies different aggregation settings to different data flows or applications based on their specific requirements. Instead of applying aggregation uniformly across all traffic, the system enables aggregation only for applications that benefit from high throughput while disabling it for applications sensitive to latency, creating localized optimization for each application.
2Productivity
If data aggregation is enabled to reduce overhead, then transmission efficiency is improved, but user experience deteriorates for real-time applications
Solution Approach 1:
The system dynamically adjusts aggregation settings based on real-time detection of application types. When a low-latency application is detected, the system disables aggregation to improve responsiveness and user experience. When throughput-intensive applications are detected, aggregation is enabled to maximize transmission efficiency.
Solution Approach 2:
The patent changes the aggregation parameter (enabled/disabled state) based on application characteristics. By monitoring application behavior and requirements, the system modifies the aggregation parameter to optimize both transmission efficiency and user experience for different application scenarios.
Data Source
AI summary
The disclosure describes systems and methods for dynamically enabling and disabling data aggregation control. A device can communicate with an access point or a station. A first wireless chip in the access point can establish a wireless connection with a second wireless chip in the station. The first wireless chip and second wireless chip can negotiate during setup of the wireless connection whether to enable aggregation of data via the wireless connection. The device can detect that a flow of packets traversing the wireless connection corresponds to a low-latency application. Upon detection, the device can communicate information to the first wireless chip and the second wireless chip to cause the first wireless chip and the second wireless chip to dynamically disable the aggregation of data being communicated by the low-latency application over the wireless connection.
