How Do Cell Phones Work? Basically, a cell phone is a radio. A sophisticated one, indeed, but a radio nonetheless. When you make a call, your voice is transformed into a radio wave, sent out through the antenna on your cell phone, to a base antenna. Base antennas cover an area of approximately ten miles. As you travel, your radio signal is transferred from one tower to the next. If you've placed a call to a regular (not cell) phone, your call is transferred to a Mobile Telephone Switching Office, where it connects to the regular telephone network.
