Engineering Contradiction Analysis
1Productivity
If millimeter wave frequencies (e.g., 60 GHz) are used for high throughput wireless communication, then data throughput is improved (up to 6 Gbits/s), but propagation loss increases significantly
Solution Approach 1:
The patent divides the communication system into multiple distributed transceivers instead of using a single transceiver. Each transceiver operates at millimeter wave frequencies to provide high throughput while the distributed architecture allows for spatial diversity and cooperative communication, mitigating the high propagation loss through multiple transmission paths and signal combining techniques.
2Reliability
If distributed transceivers are deployed to mitigate propagation loss, then link reliability is improved, but system complexity increases
Solution Approach 1:
The patent combines multiple distributed transceivers into a coordinated network where they work together as a unified system. The transceivers share channel information and coordinate their transmission and reception operations, allowing the system to achieve improved link reliability through diversity while managing complexity through centralized coordination and information sharing protocols.
3Reliability
If adaptive displacement of transceivers is implemented to optimize channel response, then link capacity is improved, but device mobility requirements and system control complexity increase
Solution Approach 1:
The patent implements a feedback mechanism where transceivers continuously monitor channel response matrices and exchange this information with the coordinating entity. Based on the feedback about channel conditions, the system dynamically adjusts transceiver positions and beamforming parameters to optimize link capacity, ensuring that the adaptive displacement is guided by real-time channel state information.
4Productivity
If phase conditions are adjusted to improve channel response matrices, then communication efficiency is improved, but signal processing complexity increases
Solution Approach 1:
The patent performs preliminary channel characterization by having transceivers exchange training signals and measure channel response matrices before actual data transmission. Based on these preliminary measurements, the system pre-calculates optimal phase conditions and beamforming weights, which are then applied during data transmission to improve communication efficiency without requiring complex real-time signal processing.
