RADIO SIGNAL LOSS TRACKER

摘要

A mobile telephone is described. The mobile telephone includes a radio transceiver for transmitting a radio signal based on a measured signal strength of a cellular signal received from a remote transceiver. A processor is coupled to the radio transceiver. The processor monitors the measured signal strength over time and determines when the measured signal strength decreases to a predetermined threshold. A memory is coupled to the radio transceiver for storing the measured signal strength. A display indicates a time when the measured signal strength decreases to the predetermined threshold.
