Wi-Fi Mesh Signal Coverage Control with Adaptive Power and MCS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Wi-Fi mesh systems suffer from excess signal interference due to devices transmitting data at inappropriate transmission powers and using the same modulation and coding schemes (MCS), which do not account for signal travel distance or interference from other devices, leading to reduced effectiveness of MCS in reducing interference.
Innovation Solution
A network configuration system determines a client device's coverage and data requirements by analyzing throughput and throughput margins, adjusting transmission power and MCS to optimize Wi-Fi configurations, using machine learning models to predict data transmission needs and minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If devices transmit data at high transmission power to extend coverage, then coverage area is improved, but signal interference increases
Solution Approach 1:
The system assigns different transmission powers to different client devices based on their specific coverage requirements and locations. Each device operates at an optimized transmission power level tailored to its local needs rather than using a uniform high power setting, thereby extending coverage where needed while minimizing unnecessary interference in other areas.
Solution Approach 2:
The system dynamically adjusts the transmission power parameter for each client device based on real-time network conditions, coverage requirements, and interference levels. This parameter optimization allows the network to achieve adequate coverage while reducing overall signal interference by preventing excessive transmission power usage.
2Adaptability or versatility
If all devices use the same MCS, then device compatibility is improved, but interference reduction effectiveness deteriorates
Solution Approach 1:
The system assigns different MCS values to different client devices based on their specific channel conditions, data requirements, and interference environments. This localized optimization allows each device to use the most appropriate MCS for its situation, improving interference reduction effectiveness while maintaining compatibility through support for multiple MCS levels.
Solution Approach 2:
The system enables dynamic MCS selection that can change over time based on varying network conditions, device requirements, and interference levels. This dynamic adaptation allows the network to optimize interference reduction while maintaining device compatibility through flexible MCS assignment rather than static uniform MCS usage.
3Productivity
If transmission power is increased to meet data requirements, then data throughput is improved, but energy consumption increases
Solution Approach 1:
The system optimizes transmission power parameters to achieve the minimum necessary power levels required to meet each client device's data throughput requirements. By precisely tuning transmission power rather than using high fixed power settings, the system maintains adequate data throughput while minimizing energy consumption.
Solution Approach 2:
The system enables client devices to self-adjust their transmission power based on their specific data requirements, network conditions, and power availability. This self-service approach allows devices to use higher power when data throughput is critical and lower power when adequate throughput is achieved, optimizing the trade-off between productivity and energy consumption autonomously.
