How does my tiny phone communicate with a cell tower so far away? How does it transmit my data to the cell tower?

The key point is that the tower is **NOT** far away. A **”cell”** is the area that each tower covers, and there are many, many towers everywhere. As you travel around, you’re moving from cell to cell, and your cellular phone switches its connection to the closest tower that covers each cell. That’s the #1 reason why your cell phone doesn’t need a large antenna. A CB/walkie-talkie two-way radio, on the other hand, **does** need a large antenna because it broadcasts directly from device to device.
