1. A system comprising:

  • a computer processor;

    a three dimensional antenna coupled to the computer processor, the three dimensional antenna comprising a transmitter and a receiver; and

    a mobile device comprising a receiver and a transmitter;

    wherein the three dimensional antenna and the mobile device are configured to wirelessly communicate;

    wherein the computer processor is configured to calculate one or more of a phase of arrival and a phase difference of arrival as a function of the wireless communication between the three dimensional antenna and the mobile device, and is further configured to calculate a distance between the three dimensional antenna and the mobile device as a function of one or more of the phase of arrival and the phase difference of arrival and the signal strength;

    wherein the computer processor is configured to calculate a direction between the three dimensional antenna and the mobile device;

    wherein the direction calculation comprises calculating an angular spread function of multipath scattering in the communication between the three dimensional antenna and the mobile device; and

    wherein the direction calculation comprises an estimation of a propagation delay and an angle in the communication between the three dimensional antenna and the mobile device.
