ABSTRACT:
An apparatus (135), method and computer program are provided for determining and indicating a quality of a signal received by a first wireless communication device (105) from a second wireless communication device (110). In one embodiment, the apparatus (135) includes a bit-error-rate (BER) circuit (215) for measuring a BER of the signal, a comparator (145) for comparing the BER with a predetermined value to determine a relative signal quality, and an indicator (160) for indicating the quality of the signal to a user of the first device (105). Alternatively, the apparatus (135) includes a circuit for measuring the strength of the signal (230), a calculator (235) for calculating a signal-to-noise ratio (SNR) of the signal using the strength of the signal and a predetermined noise value, and a comparator (145) for comparing the SNR with a predetermined value to determine a relative signal quality. Signal quality is indicated by activating a number of characters (210) corresponding to the relative signal quality.
