ABSTRACT:
A wireless terminal is disclosed that functions as both a telecommunications device and as a wireless test tool. Illustratively, the terminal comprises a first electro-acoustic transducer for converting a first acoustic signal into an outgoing signal; a wireless transmitter capable of transmitting the outgoing signal to a remote base station; a wireless receiver capable of receiving a plurality of incoming signals from the base station; a second electro-acoustic transducer for converting one of the plurality of incoming signals into a second acoustic signal; a visual display; and a terminal processor for determining a power level for each of the plurality of incoming signals and for contemporaneously displaying an indicium of the power level for each of the plurality of incoming signals onto the visual display.
