How do cordless phones work?
Answers: A cordless phone (handset) is a radio transceiver (transmitter/receiver) that operates on two radio frequency nouns carriers (RF carriers) simultaneously. It simultaneously receive and transmits at different frequencies, so you can carry on a conversation near someone, where respectively of you can always hear what the other is motto.
The handset communicates by RF signals beside the base station (where you set the phone down to charge). The transmit concentrate from the handset is received by the stub station and is turned into an audio signal (your voice). The base station converts the voice of the personage on the other end of the phone into the RF receive focus, which you then hear on your phone.
The phone line that plugs into the put money on of the base station is afterwards how the system is connected to the regular phone lines.
BTW - if you didn't have two RF channel (one for transmit and one for receive) that could operate simultaneously, only one creature could transmit (talk) at a time. You would then hold the equivalent of a walkie-talkie.
