Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless networks are set up in high-density areas to accommodate increasing wireless devices, then network coverage and device connectivity are improved, but wireless interference between overlapping coverage areas increases
Solution Approach 1:
The system dynamically adjusts channel assignments and transmission power levels based on real-time interference measurements and network conditions. Access points can switch between different channels and modify their power levels adaptively to maintain optimal performance while minimizing interference to other networks.
Solution Approach 2:
The system changes key operating parameters including channel frequency, transmission power level, and timing synchronization offsets to resolve interference. By monitoring interference levels and adjusting these parameters dynamically, the system maintains network coverage while reducing harmful interference effects.
2Area of stationary object
If access points increase transmission power to extend coverage area, then network coverage is improved, but interference to other wireless networks increases
Solution Approach 1:
Transmission power levels are dynamically adjusted based on real-time measurements of interference impact on neighboring networks. The system continuously monitors channel conditions and adapts power levels to extend coverage when possible while preventing excessive interference to other access points.
Solution Approach 2:
The system implements feedback mechanisms where access points monitor interference levels caused by their transmissions and adjust their power levels accordingly. This closed-loop control allows the system to optimize coverage area while maintaining acceptable interference thresholds for surrounding networks.
3Productivity
If multiple access points operate on the same channel to improve network capacity, then network throughput is improved, but interference between access points increases
Solution Approach 1:
The system segments the wireless spectrum by assigning different channels to different access points based on spatial distribution and interference measurements. This segmentation allows multiple access points to operate simultaneously with minimal interference, maintaining overall network throughput capacity.
Solution Approach 2:
Different regions of the network are assigned different channel configurations based on local interference conditions. Access points in areas with high interference are assigned different channels than those in low-interference areas, optimizing local throughput while minimizing overall network interference.
