1. A method comprising:

  • using tropospheric scatter to transmit a training signal from each antenna of a base station to each of a plurality of client devices, each of the client devices analyzing each training signal to generate channel characterization data, and transmitting the channel characterization data back to the base station;

    storing the channel characterization data for each of the plurality of client devices;

    receiving data to be transmitted to each of the client devices; and

    precoding the data using the channel characterization data associated with each respective client device to generate precoded data signals for each antenna of the base station; and

    using tropospheric scatter to transmit the precoded data signals through each antenna of the base station to each respective client device.
