The Phone in Your Hand: How ECE Builds the Ultimate Device

What is really happening inside your smartphone when you press a button? In this lecture, Professor Jennifer Graham, reveals the hardware and wireless magic that makes it all work. We journey deep inside the phone to explore the tiny, powerful computer chips that act as its brain, along with the screen, camera, and other components. Then, we talk about how your phone stays connected to the world wirelessly. We explain how your phone's built-in antennas send out invisible radio signals that talk to cell towers for calls and messages.

Learn how electrical and computer engineers combine all this technology to create the powerful device you use every day.
