Antenna noise temperature is determined for a handheld wireless communication device which typically includes a radio, e.g. having a wireless transceiver and associated circuitry connected thereto, and an antenna connected to the radio. The method includes measuring an antenna thermal noise component, measuring a radio noise component, measuring an environmental background noise component, and determining the antenna noise temperature based upon the measured antenna thermal noise, radio noise, and environmental background noise components. The method may include measuring antenna efficiency, and determining further includes weighting at least one of the measured antenna thermal noise, radio noise and environmental background noise components based upon the measured antenna efficiency.
