A system comprising sensor devices with radiofrequency radio receivers operating in the 2-6 GHz range and a data server that captures, processes, and analyzes WiFi protocol management transmissions from mobile devices to determine device quantity, type, transmission quality, and visit data, using statistical analysis of signal strengths to locate devices within a venue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor devices capture and record WiFi protocol management transmissions from mobile devices, then measurement precision of device quantity and transmission quality is improved, but device complexity of the system increases
Solution Approach 1:
The system divides the measurement function into multiple sensor devices distributed throughout the geographical area, each independently capturing WiFi transmissions. This segmentation allows precise local measurements while distributing system complexity across multiple simple units rather than requiring one complex centralized device.
Solution Approach 2:
The sensor devices are designed to perform multiple functions: capturing WiFi protocol management transmissions, recording transmission data, determining device quantity, and assessing transmission quality. This multi-functionality reduces the need for separate specialized devices, thereby managing device complexity while maintaining measurement precision.
2Loss of information
If the system analyzes transmission data from multiple sensor devices to determine venue visit data, then information completeness is improved, but loss of time in data processing increases
Solution Approach 1:
Sensor devices continuously capture and pre-process WiFi transmission data, maintaining ready-to-analyze records of transmission signal strength, device identifiers, and timestamps. This preliminary action ensures that when venue visit data analysis is needed, the information is already organized and available, reducing processing time while maintaining information completeness.
3Measurement precision
If radiofrequency radio receivers operate in the 2-6 GHz range to capture WiFi transmissions, then measurement precision of transmission quality is improved, but use of energy by sensor devices increases
Solution Approach 1:
The system operates radiofrequency receivers in the 2-6 GHz range, which covers WiFi transmission frequencies. By tuning receivers to this specific parameter range, the system achieves precise measurement of transmission quality while energy consumption is managed through selective frequency monitoring rather than continuous full-spectrum scanning.
