1Ease of manufacture
If fixed wireless technologies are used to reduce build costs and build times, then installation cost and time are reduced, but network performance and coverage quality may deteriorate
Solution Approach 1:
The system performs preliminary analysis and optimization of network topology before actual deployment. It evaluates multiple topology combinations and selects optimal configurations that balance cost and performance requirements, thereby ensuring network performance is maintained while reducing installation costs.
Solution Approach 2:
The system changes key parameters such as signal strength thresholds, bandwidth requirements, and coverage area specifications to optimize the balance between installation cost and network performance. By adjusting these parameters, the system identifies optimal fixed-wireless configurations that meet performance criteria while minimizing deployment costs.
2Reliability
If numerous topology combinations are evaluated to ensure coverage, then coverage quality is improved, but complexity of network design increases
Solution Approach 1:
The system segments the network design process into distinct evaluation stages, analyzing topology combinations systematically. It divides the complex design space into manageable components such as coverage analysis, cost evaluation, and performance assessment, making the overall design process more tractable while ensuring comprehensive coverage quality.
Solution Approach 2:
The system uses computational models and simulations to create virtual copies of network topologies for evaluation. By analyzing simulated network behaviors rather than physical deployments, it can assess numerous topology combinations for coverage quality without proportionally increasing actual design complexity.
3Ease of manufacture
If optimal topology selection is performed to minimize installation cost, then installation cost is reduced, but coverage quality and signal strength may deteriorate
Solution Approach 1:
The system adjusts coverage quality parameters such as minimum signal strength thresholds, bandwidth requirements, and coverage area specifications during optimization. By dynamically changing these parameters, it identifies topology configurations that achieve acceptable coverage quality at minimized installation costs.
Solution Approach 2:
The system performs preliminary evaluation of cost-performance trade-offs before final topology selection. It pre-assesses how different topology configurations affect both installation cost and coverage quality, enabling selection of optimal configurations that balance these competing requirements.
