Claim:
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.
