Abstract: A method and apparatus for implementing host-centric antenna control. An apparatus may include a plurality of antennas for wireless transmission and reception, a wireless modem for processing a signal for wireless transmission and reception via the antennas, a processor (host), and an antenna tuner circuitry. The processor is configured to run an antenna tuner software module configured to generate a control signal to configure at least one antenna. The antenna tuner circuitry is configured to switch or tune the at least one antenna based on the control signal. The apparatus may include at least one sensor coupled to the processor. The antenna tuner software module may be configured to generate the control signal based on inputs from the at least one sensor. The antenna tuner software module may be configured to receive RF parameters from the wireless modem and generate the control signal based on the RF parameters.
