Abstract

A method and apparatus for focused communication is disclosed. The method includes a base transmitter array in communication with at least one client device at the same frequency. The base transmitter array provides a focused data communication to the client device.

Claims

1. A wireless communication system comprising:

a first subset of a plurality of antenna elements, wherein the first subset form a plurality of directional lobes that are monitored for a new client device;

a second subset of the plurality of antenna elements;

an array controller that is communicatively coupled to the plurality of antenna elements;

wherein the array controller;

detects, using the first subset of the plurality of antenna elements, a first signal from the new client device,

determines a first location of the new client device in three-dimensional space based on a reverse timing, wherein the reverse timing is a difference between a time when the first signal is received by a first antenna element and a second antenna element of the first subset of the plurality of antenna elements,

tunes the second subset of the plurality of antenna elements to generate constructive interference of an electromagnetic wave at the first location; and

transmits, using the second subset of the plurality of antenna elements, the electromagnetic wave to the new client device.

2. The wireless communication system of claim 1, wherein the reverse timing for each of the plurality of antennae elements is further calculated by:

recording a respective input time offset of the first signal for each respective antennae element; and

calculating the reverse timing for each of the plurality of antennae elements based on the respective input time offset.

3. The wireless communication system of claim 1, wherein the array controller further:

detects, using the first subset of the plurality of antenna elements, a second signal from the new client device;

determines a second location of the new device in three-dimensional space based on a reverse timing of the second signal; and

generates, using the second subset of the plurality of antenna elements, constructive interference of an electromagnetic wave at the second location.

4. The wireless communication system of claim 1, wherein the plurality of directional lobes include a plurality of overlap areas.

5. The wireless communication system of claim 1, wherein the array controller further:

demuxes the first signal into multiple data signals, each corresponding to one of the new client device;

prepares responsive data signals for each of the new client device;

generates an output data signal by muxing the responsive data signals; and

transmits, using the second subset of the plurality of antenna elements, the output data signal to the new client device.

6. The wireless communication system of claim 1, wherein the first location includes a height component.

7. The wireless communication system of claim 1, wherein the array controller further:

determines a motion vector for the new client device based upon the first location
