Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If millimeter wave technology is used in 5G networks, then communication speed and bandwidth are improved, but path transmission loss and wall attenuation increase
Solution Approach 1:
The patent introduces optical fiber networks as intermediary transmission channels between the core network and remote antenna units. The optical-fiber-based distribution system carries radio frequency signals over long distances with minimal loss, enabling millimeter wave technology to achieve high communication speeds while overcoming the inherent path transmission loss through the use of optical fiber as a low-loss transmission medium.
Solution Approach 2:
The patent divides the 5G network into multiple remote antenna units (RAUs) distributed across different locations, each serving specific coverage areas. This segmentation allows the system to deploy antennas on different sides of buildings and obstacles, thereby avoiding direct line-of-sight blockages and reducing the impact of wall attenuation on overall network performance.
2Device complexity
If traditional centralized network disposition is used, then system control is simplified, but deployment flexibility and adaptability to different locations decrease
Solution Approach 1:
The patent segments the traditionally centralized base station into multiple distributed remote antenna units (RAUs), each capable of independent operation and local signal processing. This segmentation enables flexible deployment in various locations without requiring complex centralized control infrastructure, as each RAU can be independently configured and managed through simplified protocols.
Solution Approach 2:
The patent designs universal remote antenna units that can be deployed in multiple configurations and locations. Each RAU is equipped with universal interfaces and standardized protocols that enable them to function in different roles (transmission, reception, relay) and be integrated into various network architectures, thereby providing deployment flexibility while maintaining relatively simple system control through standardized management.
3Reliability
If optical-electrical conversion and one-to-many conversion devices are deployed, then signal transmission quality is improved, but system component complexity increases
Solution Approach 1:
The patent combines multiple conversion functions (optical-to-electrical conversion, electrical-to-optical conversion, and one-to-many signal distribution) into integrated remote antenna units. By merging these functions into unified devices rather than using separate components, the system achieves high signal transmission quality through proper conversion while reducing the overall number of discrete components and simplifying system architecture.
