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 method for wirelessly transmitting focused data, comprising:

tuning a first subset of a plurality of antenna array elements to form a plurality of coverage lobes in 3-dimensional space, wherein the plurality of antenna array elements receive electromagnetic radiation;

detecting one or more first new client devices in at least one of the plurality of coverage lobes;

receiving, by the first subset, a first message from the one or more first new client devices;

determining a first location of the one or more first new client devices in three-dimensional space based on the first message based upon a reverse timing offset for one or more of the plurality of antenna array elements, the reverse timing offset calculated by recording input time offsets of the first message received by the first subset and calculating the reverse timing offset based on the input time offsets;

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

transmitting, by the first subset and second subset, the electromagnetic wave to the one or more first devices.

2. The method of claim 1, further comprising:

detecting one or more second new client devices in at least one of the plurality of coverage lobes;

receiving a second message from the one or more second new client devices;

determining a second location of the one or more first new client devices in three-dimensional space based on the second message based upon a reverse timing offset for one or more of the plurality of antenna array elements, the reverse timing offset calculated by recording input time offsets of the second message received by the first subset and calculating the reverse timing offset based on the input time offsets; and

tuning a third subset of the plurality of antenna array elements to generate constructive interference at the second location.

3. The method of claim 2, further comprising:

transmitting the electromagnetic wave at a first frequency to the one or more first client devices and a second frequency to the one or more second client devices.

4. The method of claim 1, wherein the first location includes a height component.

5. The method of claim 1, further comprising:

determining a motion vector for the one or more first new client devices based upon the first location.

6. A base transmitter array comprising:

a plurality of transceivers and a plurality of antenna elements, wherein the antenna elements receives electromagnetic radiation,

wherein the base transmitter array is configured to;

tune a first subset of the plurality of antenna elements to form a plurality of coverage lobes in three-dimensional space;

detect one or more first new client devices in at least one of the plurality of coverage lobes;

receive a first message from the one or more first new client devices;

determine a first location of the one or more first new client devices in three-dimensional space based on the first message based on a reverse timing offset for one or more of the plurality of antenna array elements is calculated by the base transmitter array recording input time offsets of the first message received by the first subset and calculating the reverse timing offset based on the input time offsets by subtracting the input time offsets from a maximum time offset;

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

transmit the electromagnetic wave to the one or more first devices.

7. The transmitter of claim 6, wherein the base transmitter array is further configured to:

detect one or more second new client devices in at least one of the plurality of coverage lobes;

receive a second message from the one or more second new client devices;

determine a second location of the one or more first new client devices in three-dimensional space based on the second message based upon a reverse timing offset for one or more of the plurality of antenna array elements, the reverse timing offset calculated by recording input time offsets of the second message received by the first subset and calculating the reverse timing offset based on the input time offsets; and

tune a third subset of the plurality of antenna array elements to generate constructive interference at the second location.

8. The transmitter of claim 7, wherein the base transmitter array is further configured to:

transmit the electromagnetic wave at a first frequency to the one or more first client devices and a second frequency to the one or more second client devices.

9. The transmitter of claim 6, wherein the first location includes a height component.

10. The transmitter of claim 6, wherein the base transmitter array is further configured to:

determine a motion vector for the one or more first new client devices based upon the first location.
