Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio communication systems in the 60 GHz band using directional antennas face communication failures due to obstacles, leading to interruptions in high-speed data exchange, which are not effectively addressed by conventional diversity technologies, especially in systems without feedback signals or in open-loop systems.
Innovation Solution
An apparatus and method for transmitting and receiving streaming data using multiple paths, which includes a path managing module to maintain sequence information, a data transmitting module to frame and transmit data, a data receiving module to verify data integrity, and a restoring module to correct corrupted data, allowing continuous data exchange without separate control signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If diversity technologies using multiple paths are employed, then communication reliability is improved, but the system complexity increases and requires feedback signals that are not available in open-loop systems
Solution Approach 1:
The transmission path is segmented into multiple independent paths (direct path and reflected paths). Data is divided and transmitted through these separate paths simultaneously, allowing the receiver to combine them for improved reliability without requiring complex feedback mechanisms
Solution Approach 2:
The system pre-establishes multiple transmission paths including direct and reflected paths before communication begins. Path selection and combination strategies are predetermined, eliminating the need for real-time feedback and complex dynamic path management
2Reliability
If conventional multiple path diversity technologies are used, then path interruption is detected, but the detection requires data receiving-acknowledgement control signals that are not available in high-speed real-time systems
Solution Approach 1:
The system uses the transmitted data itself as the verification mechanism. By transmitting identical or redundant data through multiple paths and comparing received data across paths, the system self-verifies path integrity without requiring separate acknowledgment signals
Solution Approach 2:
Data transmission and path verification occur continuously and simultaneously. The useful action of data transmission serves dual purposes: delivering information and verifying path status, eliminating idle time for separate control signal exchange
3Productivity
If directional antennas are used in 60 GHz band, then data exchange speed is improved to about 3 Gbps, but communication failures occur when obstacles interrupt the path
Solution Approach 1:
The system transitions from a single-dimensional direct path to multi-dimensional paths by utilizing reflected waves off surfaces such as walls and ceilings. This adds spatial dimensions to the transmission paths, maintaining high-speed directional communication while providing alternative routes when obstacles block the direct path
