Development of an empirical path-loss model for street-light telemetry at 868 and 915 MHz

This paper presents an initial empirical path-loss propagation model for communication links operating at streetlight/ roof-top heights over the ranges of 100 m to 10 km in urban and suburban environments. The statistical path-loss model presented uses data taken from a significant number of deployed street-light telemetry systems transmitting in the licence exempt/ ISM bands at 868 and 915 MHz. This propagation model provides a valuable tool for network planning where typical cellular propagation models might not be appropriate.
