The science behind how WiFi internet connectivity works


Our Telegraph video series, How It Works, breaks down the basics of everyday technology, revealing how the products we use on a daily basis actually work.

The video above reveals how WiFi internet connectivity works, connecting to a computer by converting electronic data into digital signals via an internet router.

The basis of wireless internet technology is much like a traditional radio transmission, where an electronic current is passed from one antenna to another via an electro magnetic wave. However, WiFi uses a digital signal with a much more complex pattern of modulation to transmit the data in binary code.

This is the final episode in our How It Works series. Previous episodes have focused on how GPS connectivity works, the science behind how a battery works and exactly how a touchscreen works.
