## Do cell phones use radio waves?

Cell phones send signals to (and receive them from) nearby cell towers (base stations) using RF waves. This is a form of energy in the electromagnetic spectrum that falls between FM radio waves and microwaves. Like FM radio waves, microwaves, visible light, and heat, RF waves are a form of non-ionizing radiation.

## How does cell phone signal travel?

Cell phones use radio waves to communicate. Radio waves transport digitized voice or data in the form of oscillating electric and magnetic fields, called the electromagnetic field (EMF). … Radio waves carry the information and travel in air at the speed of light. Cell phones transmit radio waves in all directions.

## Do cell phones send signals when off?
