Abstract
A method and system for predicting radio frequency (RF) coverage in a multi-level wireless network is described herein. The multi-level wireless network includes the network management server and a plurality of wireless devices, where each of the wireless devices includes an RF transmitter. A two-dimensional wireless network configuration model of a vertical level of the multi-level wireless network is determined. A path loss in a propagation path of an RF signal from an RF transmitter of a wireless device to a grid point in the vertical level is determined. The path loss may be based on a plurality of path loss exponents. A signal strength loss due to one or more obstacles that intersect the propagation path is determined. A strength of the RF signal is predicted based on the path loss and the signal strength loss.
