1Area of stationary object
If range-extending devices are deployed to increase network range, then connectivity coverage is improved, but device placement optimization becomes more complex
Solution Approach 1:
The system continuously monitors signal quality metrics (RSSI, SNR) from wireless devices and uses this feedback to automatically adjust range-extending device locations. The controller receives signal quality information, compares it against thresholds, and modifies device positions to optimize connectivity while reducing placement complexity through automation.
Solution Approach 2:
The range-extending devices perform self-optimization by automatically adjusting their own locations based on monitored signal quality. The devices independently respond to connectivity needs without requiring manual intervention, allowing the system to self-adjust and optimize network coverage dynamically.
2Measurement precision
If multiple signal quality measurements are taken during extended time periods, then measurement precision is improved, but time consumption increases
Solution Approach 1:
The system performs signal quality measurements at strategically selected intervals rather than continuously, taking partial measurements that are sufficient to detect connectivity changes. The controller determines appropriate measurement frequencies based on network conditions, avoiding excessive measurements while maintaining adequate precision to trigger optimizations when needed.

AI summary
Systems, apparatuses, and methods are described for determining locations for range-extending devices. Signal strength between devices within an area may be measured one or more times over a time period. Based on the measurements, signal loss over fronthaul links and backhaul links may be determined for each range-extending device in the area. A predicted improvement in signal quality may be determined. A direction and distance to move each range-extending device may be determined based on a comparison with the fronthaul and backhaul signal qualities and the predicted improvement in signal quality. The direction, improvement in signal quality, and/or user preferences for devices may be used to determine an improvement associated with moving one or more range-extending devices.
