ABSTRACT:
A system and method for invoking one or more features of a wireless device when a signal strength of a channel approaches or drops below an RSSI threshold of the channel is disclosed. An embodiment of the invention includes the steps of (1) obtaining the RSSI threshold for the channel; (2) monitoring the signal strength during an operation mode of the wireless device; and (3) invoking the feature when the signal strength approaches a predetermined limit of the RSSI threshold. In an implementation on a cordless telephone, the feature can include playing a warning, switching to a different channel, or returning a telephone line to an idle state.
