Bluetooth, different higher-frequency wavelengths are responsible for allowing us to talk on the phone with our friends and loved ones. A smartphone operates just like a two-way radio. When we talk face to face with someone, we hear what is called an analog sound . Smartphones work by converting these analog sounds into electric signals and transmitting them over wavelengths to mobile network towers and satellites. These signals travel at the speed of light across the mobile network until the designated device receives them. Physics comes into play during this transfer of information. Smartphones convert signals from a global positioning system (GPS) and Wi-Fi networks as well, translating radio waves into understandable information.

Smartphones transmit and receive signals to and from networks of cell phone towers.
