Engineering Contradiction Analysis
1Measurement precision
If traditional direct measurement methods are used for channel utilization, then measurement simplicity is maintained, but measurement precision deteriorates because devices unable to decode signals or operating outside channels cannot provide accurate data
Solution Approach 1:
The patent introduces an estimation engine as an intermediary component that receives channel utilization values from multiple wireless devices and applies mathematical relationships to estimate the channel utilization for target devices. This mediator enables accurate estimation for devices that cannot directly provide measurements, resolving the contradiction between measurement precision and device complexity by adding a centralized estimation function rather than requiring complex modifications to each device
Solution Approach 2:
The system pre-establishes mathematical relationships between different wireless devices during a calibration phase, storing these relationships for later use in estimation. This preliminary action allows the estimation engine to quickly compute accurate channel utilization values without real-time complex calculations, improving measurement precision while keeping the operational system complexity manageable
2Measurement precision
If channel scanning is performed frequently to improve accuracy, then measurement precision improves, but productivity deteriorates due to increased time consumption and network overhead
Solution Approach 1:
The patent merges channel utilization measurements from multiple wireless devices operating on different channels into a unified estimation for the target device. By combining data from multiple sources and applying mathematical relationships, the system achieves high measurement precision without requiring any single device to perform frequent exhaustive scanning, thus maintaining network productivity
Solution Approach 2:
Instead of requiring the target device to directly measure channel utilization on channels it is not operating on, the system copies measurement data from other devices that are operating on those channels and applies transformation relationships to estimate the target device's channel utilization. This copying approach provides accurate measurements without the productivity cost of frequent scanning

AI summary
Operations include estimating a channel utilization, for a target wireless device, corresponding to a set of wireless signals that are received and/or transmitted by another wireless device. One or more relationships between detected signal strength values, measured channel utilization values, and/or actual channel utilization values are determined. The estimation is made based on applying detected signal strength values received at other wireless devices, measured channel utilization values at other wireless devices, and/or actual channel utilization values at other wireless devices to the relationships.
