1. A method of wireless communication, comprising:
at a transmitter including an array of transmit antennas arranged in a focal region of a transmit lens, amplifying a plurality of first modulated RF signals through a plurality of power amplifiers according to a default gain to produce a corresponding plurality of first amplified modulated RF signals;
transmitting from each transmit antenna a respective first amplified modulated RF signal from the plurality of first amplified modulated RF signals to form a plurality of first transmitted RF signals, each first transmitted RF signal refracting through the transmit lens and near-field propagating to a receiver;
adjusting the default gain for each power amplifier responsive to a first signal quality determination for the plurality of first transmitted RF signals to form a plurality of adjusted gains; and
amplifying a plurality of second modulated RF signals through the plurality of power amplifiers according to the plurality of adjusted gains to produce a corresponding plurality of second amplified modulated RF signals.
