Dynamic Link Transition in Multi-Band Wi-Fi Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi technologies face challenges in efficiently managing and coordinating multiple frequency bands for simultaneous communication, particularly in supporting high-bandwidth and low-latency transmissions required for applications like video transmission, AR, and VR, which existing MAC mechanisms fail to address effectively.
Innovation Solution
A communication method and device that implement dynamic link transition by determining and sending message frames with information indicating link transitions, allowing devices to switch between multiple frequency bands such as 2.4 GHz, 5 GHz, and 6 GHz based on network conditions, load, and service requirements, optimizing link usage and power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple frequency bands are aggregated for simultaneous communication, then bandwidth and throughput are increased, but system complexity and coordination overhead increase
Solution Approach 1:
The patent segments the multi-band communication system into independent links, each with its own MAC layer. This allows each frequency band to operate autonomously while maintaining overall system coordination, reducing the complexity of managing multiple bands simultaneously while preserving the throughput benefits of aggregation.
2Productivity
If link transition is performed dynamically, then communication efficiency is improved, but switching latency and overhead increase
Solution Approach 1:
The patent establishes multiple links and prepares transition paths in advance before they are needed. By pre-configuring backup links and maintaining them in a ready state, the system can perform link transitions quickly when required, improving communication efficiency while minimizing switching latency through proactive preparation.
