Patent Images
1. A method of constructing a map of a physical environment for radio signal propagation comprising:
- determining a wireless signal propagation model;
receiving at a receiver unit a wireless communication signal from a transmitter unit;
storing a strength of said received wireless communication signal and associated locations of said receiver unit and said transmitter unit;
modifying said wireless signal propagation model based at least on said stored strength of said wireless communication signal and said associated locations of said receiver unit and said transmitter unit;
constructing a map comprising locations of one or more obstacles based on said modified wireless signal propagation model.
