Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional private 5G networks use significant bandwidth for control channels, then network reliability is improved, but throughput is reduced
Solution Approach 1:
The patent segments the network into distinct control channels and data channels, separating their bandwidth requirements. Control channels use dedicated bandwidth for reliability, while data channels utilize remaining bandwidth for throughput, resolving the contradiction between these two performance aspects
Solution Approach 2:
The patent introduces a mesh network topology that adds spatial dimensionality to bandwidth utilization. By creating multiple routing paths through mesh architecture, the system can distribute data traffic across different routes, improving throughput without compromising control channel reliability
2Adaptability or versatility
If access point devices use mesh network topology with multiple frequency bands, then network adaptability is improved, but device complexity increases
Solution Approach 1:
The access point devices are designed with multi-functionality, supporting multiple frequency bands (licensed and unlicensed) and multiple communication protocols (5G NR and Wi-Fi 6). This universal design enables the same device to adapt to various network conditions and scenarios, improving network adaptability
Solution Approach 2:
The mesh network implements self-optimizing capabilities where access point devices automatically discover neighboring nodes, select optimal frequency bands, and establish routing paths without manual configuration. This self-service approach simplifies deployment and operation, managing device complexity through automation
