An Adaptive Segmental Model for Accurate Signal Propagation and RSS Prediction

International Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.
Received signal strength (RSS) is a key metric for assessing the strength of a received signal. However, indoor signal stability is affected by multiple factors, leading to RSS fluctuations even at fixed locations. These variations necessitate a more adaptive calculation method for complex scenarios.
