Multi-Bandwidth Data Transmission in WLANs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems lack a concrete method for transmitting and receiving data in new frequency bands, particularly for supporting multi-bandwidth, which is essential for stable high-speed data transmission in wireless local area networks (WLANs).
Innovation Solution
A data transmission apparatus and method that configures a frame in a new frequency band to support multi-bandwidth modes, including ½×, basic, 2×, 4×, and 8× bandwidths of the basic frequency band, using a verification unit to identify suitable frequency bands and generate data packets for transmission and reception, and a recovery unit to recover data packets in these modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data transmission is performed in a new frequency band without a concrete frame configuration method, then high transmission rate can be achieved, but stable data transmission cannot be guaranteed
Solution Approach 1:
The frequency band is segmented into multiple bandwidth modes (1/2×, basic, 2×, 4×, 8× bandwidth of the basic frequency band), allowing the system to divide the new frequency band into manageable segments that can be configured with appropriate frame structures for stable transmission
Solution Approach 2:
The frame configuration parameters are changed to support multi-bandwidth modes in the new frequency band, including verifying basic frequency band capabilities and generating data packets with appropriate bandwidth mode indicators to ensure stable transmission at high rates
2Ease of manufacture
If a fixed frame configuration is used in the new frequency band, then implementation is simplified, but adaptability to different bandwidth requirements is reduced
Solution Approach 1:
The frame configuration is made dynamic by introducing multiple bandwidth modes (1/2×, basic, 2×, 4×, 8× bandwidth) that can be selected and verified based on channel conditions and terminal capabilities, allowing the system to adapt between simplicity and versatility as needed
Solution Approach 2:
The frame structure is designed with universal multi-functionality to support multiple bandwidth modes within the new frequency band, where a single frame configuration method can handle various bandwidth requirements through verification of basic frequency band capabilities and appropriate mode selection
