Wireless Frame Segmentation for Multi-Protocol Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently transmitting high-data-rate signals across multiple channels, particularly in the 60 GHz range, due to limitations in compatibility between different communication protocols and the need for flexible frame formats that can be decoded by various devices.
Innovation Solution
The development of a wireless communication apparatus and method that generates frames comprising a preamble, header, and data payload, where the preamble and header are decodable by multiple protocols, while the data payload is specific to a first protocol, enabling efficient transmission across different communication standards and channel configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is transmitted using a protocol-specific frame format, then data transmission efficiency is improved, but compatibility with devices operating under different protocols deteriorates
Solution Approach 1:
The frame is divided into distinct segments: a universal preamble and header that are decodable by multiple protocols, and a protocol-specific data payload. This segmentation allows different protocol layers to operate independently, with the universal portion ensuring compatibility and the specific portion optimizing transmission efficiency for the target protocol.
Solution Approach 2:
The preamble and header are designed with universal functionality to be decodable by devices operating under multiple different protocols. This multi-functionality enables a single frame structure to serve multiple protocol types simultaneously, ensuring broad compatibility while maintaining efficient data transmission capabilities.
2Adaptability or versatility
If a universal frame format is used for multi-protocol compatibility, then adaptability across protocols is improved, but data transmission efficiency for specific protocols deteriorates
Solution Approach 1:
Different portions of the frame have different quality characteristics optimized for their specific functions. The preamble and header use a universal format with broad compatibility qualities, while the data payload uses protocol-specific formatting with optimized transmission efficiency qualities. This local differentiation resolves the contradiction by allowing each section to excel at its primary function.
3Measurement precision
If protocol-specific data payload is transmitted, then data transmission precision is improved, but decodability by devices operating under different protocols deteriorates
Solution Approach 1:
The protocol-specific data payload is extracted and separated from the universal preamble and header. This extraction allows the data payload to maintain high transmission precision for its specific protocol while the universal portions remain intact for multi-protocol decodability. Devices can decode the universal portions regardless of protocol, while full precision is achieved for the specific protocol data.
