1. A location verification device, comprising:
one or more receivers, configured to receive a wireless signal from a transmitting device, wherein the wireless signal represents data from the transmitting device;
wherein the data comprise position coordinates that correspond to a reported position of the transmitting device; and
one or more processors, configured to:
determine using the received wireless signal an actual signal characteristic of the received wireless signal, wherein the actual signal characteristic of the received wireless signal comprises an actual angle of arrival, an actual received power, an actual path loss, or an actual time of flight of the received wireless signal;
determine an expected signal characteristic of the received wireless signal, wherein the expected signal characteristic of the received wireless signal comprises an expected angle of arrival, an expected received power, or an expected time of flight of a signal from the reported position to a current position of the location verification device;
compare the actual signal characteristic with the expected signal characteristic; and
accept the reported position if the comparison of the actual signal characteristic and the expected signal characteristic is within a predetermined range; and
reject the reported position if the comparison between the actual signal characteristic and the expected signal characteristic is outside the predetermined range.
