Abstract
A method for determining a location of a device in a wireless network includes transmitting a digital transmit signal from a digital transmitter including a first antenna. The first antenna is configured to transmit the digital transmit signal to two or more receivers. A first receiver including a second antenna and a second receiver including a third antenna receive the digital transmit signal from the digital transmitter. The digital transmit signal arrives at the receivers at two different time instances as a first digital signal and a second digital signal. A comparison of the digital signals is performed at the processor. A time difference of arrival of the digital signals is determined at the processor based on the performed comparison. The direction of travel of the digital transmit signal is estimated at the processor. A bearing to the digital transmitter is determined.
