Beacon Systems Using Radio Waves TRIZ Cases
- Sidelink Positioning With Dynamic UE Reference Management
Fixed radio deployments can limit positioning accuracy; this case manages capable UEs as dynamic reference nodes through activation and capability data.
- Dynamic Sidelink Anchor Groups for On-Demand UE Positioning
Preconfigured anchor UEs select proximity-based PRS resources for on-demand positioning, improving reliability when base-station access is limited.
- Narrowband Beacon Circuit for Low-Power Electronic Locks
Battery-powered electronic locks use a narrowband beacon to announce timed wideband communication, reducing radio and processing demand.
- GNSS Signal Power Analysis for Urban Building Height Estimation
Comparing received with expected signal power helps estimate building height and correct GNSS errors from urban multipath and obstructions.
- Fine-Time Indoor Positioning With Strobe-Synchronized Sensors
Strobe signals capture sensor data at packet arrival times, improving indoor positioning precision through synchronized timing.
