ABSTRACT:
A wireless terminal includes an RF transceiver, an auto tuner, and an antenna. When a remote signal is received at the wireless terminal, the auto tuner is adjusted in accordance with the received signal to optimize OTA performance of the wireless terminal. As further remote signals are received by the wireless terminal, the tuner is readjusted. As a user inputs information to be transmitted, the tuner is also readjusted in accordance with the transmission signals to optimize OTA performance of the wireless terminal, and a best compromise between the TX OTA performance and the RX OTA performance is calculated. Current/temperature information may also be obtained for readjusting the tuner.
