What does a base station do?

The base station is a fixed transceiver that acts as the primary transmission and reception communication hub for wireless devices. The base station modulates baseband information and transmits it to mobile devices. Base stations also receive mobile device transmissions, modulate them, and send them to the wireline infrastructure.

Do mobile phones need a base station?

Mobile phones and other mobile devices require a network of base stations in order to function. The base station antennas transmit and receive RF (radio frequency) signals, or radio waves, to and from mobile phones near the base station. Without these radio waves, mobile communications would not be possible.
