The cordless telephone is a device consisting of two units as follows: A) a base unit physically connected to the public utility (telecommunications network) with the ability to relay electronic signals from a handset not physically connected to the public utility; B) a handset unit with the capability to send and receive electronic signals to the base unit. The characteristics of this device allow the holder of the handset to move about without the inconvenience of being physically attached to the public utility telecommunications netwok while being in communication. Also, the cordless telephone has the capability of remaining in a standby mode, i.e. waiting for or placing telephone calls. |
