How does wireless internet works?

Answer 1

They work preety much like any other wireless device. They transfer a signal at a specific frequency in which both the transmiters and recivers are tuned to. The signals are digital though, which means they are a bunch of 0s and 1s, not literally though, they are ons or offs, ups or downs: two different types of signaling which the receiver then interprets into data.

Answer 2

Your computer has a built-in wireless adapter. That will be used to connect to the internet wirelessly. The adapter will connect to an access-point, a device called a "wireless router." It works by exchanging data back and forth and communicating with the wireless router. This is how your computer access the internet.

Answer 3

Wireless internet works by "broadcasting" the signal over a local area. For example, if your internet comes through cable, the cable would plug into a wireless router which would then transmit the signal wirelessly allowing you to utilize it without being directly plugged into the cable.
