摘要

We present a 2.4 GHz narrowband multi-lateration-based RF positioning system that achieves sub-meter 2D positioning accuracy when tested across multiple environments (both indoor and outdoor) with varying levels of multipath. The comprehensive multi-environment experimental evaluation demonstrates the system’s robustness to variations in the wireless environment. Additionally, practical considerat...
