Abstract:
Disclosed is a method of determining a distance between a first device and a second device in a wireless environment. The method includes steps of obtaining environmental parameters in a LOS propagation environment; determining whether the environment between the first device and the second device is the LOS propagation environment or a NLOS propagation environment; and calculating, based on the determination result of the determining step, the distance between the first device and the second device by utilizing the environmental parameters in the LOS or NLOS propagation environment as well as a path loss model.
