Patent ID: 8031121

Claim:
An apparatus comprises: a transmitter coupled to transmit a high carrier frequency signal; a receiver device that includes: a receiver section that includes: a first antenna operable to receive the high carrier frequency signal to produce a first received high carrier frequency signal; a second antenna operable to receive the high carrier frequency signal to produce a second received high carrier frequency signal, wherein the first and second antennas have an antenna radiation relationship; a receiver module coupled to: determine first signal properties of the first received high carrier frequency signal; and determine second signal properties of the second received high carrier frequency signal; and a processing module coupled to: determine a position of the receiver device with respect to the transmitter based on the first and second signal properties; and map the position to a coordinate system; determine a first distance between the first antenna and the transmitter by: determining a first receive power of the high carrier frequency signal received via the first antenna; determining a first path loss between the first antenna and the transmitter based on the first receive power and a transmit power; determining the first distance based on the first path loss, wherein the first signal properties includes the first receive power and the first path loss; determining a first phase rotation of the high carrier frequency signal received via the first antenna; determining a first number of cycles of the high carrier frequency signal received via the first antenna based on the first distance; and adjusting the first distance based on the first number of cycles and the first phase rotation; and determine a second distance between the second antenna and the transmitter by: determining a second receive power of the high carrier frequency signal received via the second antenna; determining a second path loss between the second antenna and the transmitter based on the second receive power and the transmit power; determining the second distance based on the second path loss, wherein the second signal properties includes the second receive power and the second path loss; determining a second phase rotation of the high carrier frequency signal received via the second antenna; determining a second number of cycles of the high carrier frequency signal received via the second antenna based on the second distance; and adjusting the second distance based on the second number of cycles and the second phase rotation; and determine a beam angle of the high carrier frequency signal with respect to the first and second antennas; and determine the position of the receiver device based on the beam angle and the first and second distances, wherein the first and second signal properties includes the beam angle.
