Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi technologies face challenges in achieving high-speed and throughput data transmission across multiple frequency bands simultaneously, which is essential for applications like video transmission, augmented reality, and virtual reality.
Innovation Solution
The proposed solution involves generating a multi-band transmission connection establishment message frame to request simultaneous data transmission on at least two frequency bands, including 2.4GHz, 5.8GHz, and 6-7GHz bands, and sending this message frame to establish simultaneous data transmission across these bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional single-band Wi-Fi transmission is used, then device complexity is low, but transmission rate and throughput are insufficient for high-demand applications
Solution Approach 1:
The patent combines multiple frequency bands (2.4GHz, 5.8GHz, 6-7GHz) into a unified transmission system, allowing simultaneous data transmission across all bands. This merging of previously separate transmission channels enables aggregate throughput that exceeds the capacity of any single band, directly resolving the contradiction between transmission rate and system complexity.
Solution Approach 2:
The invention transitions from single-band transmission to multi-band transmission by adding the frequency band dimension to the transmission system. By utilizing multiple frequency bands simultaneously rather than sequentially, the system achieves higher throughput without requiring proportional increases in device complexity for each individual band.
2Productivity
If multi-band transmission is implemented, then throughput is improved, but channel access coordination becomes more complex
Solution Approach 1:
The patent segments the channel access coordination into distinct phases: first transmitting the connection establishment message frame on all bands, then transmitting data frames. This segmentation of the transmission process into coordination phase and data transmission phase simplifies the coordination mechanism while maintaining multi-band throughput benefits.
Solution Approach 2:
The invention performs preliminary channel access coordination by first transmitting the connection establishment message frame on all frequency bands before actual data transmission begins. This preliminary action establishes the transmission parameters and coordination protocol in advance, reducing the complexity of real-time coordination during data transmission.
3Productivity
If data frames are transmitted on multiple frequency bands simultaneously, then transmission rate increases, but interference between bands may increase
Solution Approach 1:
The patent applies different transmission parameters to different frequency bands, allowing each band to be optimized for its specific characteristics. By adjusting transmission parameters locally for each band rather than using uniform settings across all bands, the system achieves high transmission rates while minimizing interference between bands.
