Engineering Contradiction Analysis
1Productivity
If mmWave communication is used for backhaul link, then higher data rates are achieved, but stability deteriorates due to low permeability and environmental susceptibility
Solution Approach 1:
The system dynamically switches between mmWave and LTE backhaul links based on real-time channel conditions. The network providing device monitors channel quality and automatically transitions between communication technologies to maintain stable service, making the backhaul link adaptive rather than static.
Solution Approach 2:
The invention changes the communication technology parameter from fixed mmWave to variable selection between mmWave and LTE. By adjusting the backhaul link technology parameter according to environmental conditions, the system achieves both high data rates when possible and stability when needed.
2Productivity
If mmWave backhaul link is deployed, then higher data rates are achieved, but installation flexibility deteriorates due to environmental constraints
Solution Approach 1:
The network providing device is designed to support multiple backhaul technologies (mmWave and LTE) universally. This multi-functionality allows the system to adapt to different installation environments and conditions, making the deployment more versatile and less constrained by environmental factors.
Solution Approach 2:
The system dynamically selects between mmWave and LTE backhaul links based on real-time channel conditions. The network providing device monitors channel quality and automatically transitions between communication technologies to maintain stable service, making the backhaul link adaptive rather than static.
3Reliability
If adaptive backhaul link configuration is implemented, then service stability is improved, but device complexity increases
Solution Approach 1:
The network providing device autonomously monitors channel conditions and performs automatic switching between mmWave and LTE backhaul links without requiring manual configuration or user intervention. The system serves itself by making intelligent decisions based on real-time environmental feedback.
Solution Approach 2:
The system implements a feedback mechanism where the network providing device continuously monitors channel quality and uses this information to automatically adjust the backhaul link configuration. This closed-loop control maintains service stability while minimizing the need for complex manual configuration.
