Abstract
An embodiment of the present invention provides an apparatus, comprising a transceiver, an antenna tuner connecting the transceiver to an antenna, a power sensor adapted to acquire measurements about transmit power, a receive signal strength indicator (RSSI) adapted to acquire measurements about receive power and wherein the tuner tunes the antenna based upon the transmit and receive measurements to optimize the antenna in both the receive and transmit bands.
Claim 1
A method, comprising: using a power sensor adapted to acquire measurements about transmit power during a first burst transmission; using a receive signal strengthindicator (RSSI) adapted to acquire measurements about receive power; and tuning an antenna coupled with a transceiver using a tuner once per frame prior to a second burst transmission based upon said transmit and receive measurements to improve saidantenna in both the receive and transmit bands, wherein both the transmit and receive measurements are simultaneously utilized in determining the tuning, and wherein the second burst transmission follows the first burst transmission in time.
