1. A method of wireless communication, comprising:
receiving communication signals on multiple input feeds;
precoding the communication signals to generate precoded signals, and
transmitting the precoded signals using an antenna sub-system to multiple wireless stations using multiple beams,
wherein the antenna sub-system comprises a Luneburg antenna of a hemispherical shape formed by a plurality of tiles,
wherein a beamwidth of at least one of the multiple beams transmitted from the Luneburg antenna is smaller than a width of a tile of the plurality of tiles,
wherein the precoding maximizes a desired signal level to interference ratio of transmissions to the multiple wireless stations.
