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 transmitting data to one or more client devices, comprising:

providing a plurality of transceivers and antenna elements in a base transmitter array;

establishing known tuned directions in the array, each tuned direction corresponding to a particular subset of the antenna elements;

receiving encoded data from one of the client devices;

tracking input time offsets of the data traversing the antenna elements;

determining a best known tuned direction in the array for one of the client devices based upon the received encoded data;

retuning the antenna elements in the other known tuned directions until they optimally receive the encoded data;

recording the input time offsets of the data traversing the transceivers in these tuned directions;

calculating a reverse timing offset based on the recorded input time offsets; and

transmitting data to the client device in response to the encoded data, wherein the plurality of antenna elements transmit based on the calculated reverse timing offset.

2. The method of claim 1, further comprising:

receiving data from multiple client devices simultaneously as a single data input signal;

demuxing the single data input signal into multiple data signals, each corresponding to one of the multiple client devices;

preparing a responsive data signal for each of the multiple client devices;

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

transmitting the output data signal to the multiple client devices.
