Wi-fi

What is wi-fi? I used it all the time, but never really knew what it was. Wi-fi uses radio waves and sends out these waves to different devices to give them the power of the internet.  They send out around 2.2GHz - 2.4 GHz, These waves have similar frequencies as mircowaves.  These waves travel through the air, undetectable by the blind eye and they send out "information" to other devices.  The reason why people lose connection to their wi-fi after traveling some distance is that waves can only travel a certain distance.  Also the reason why wi-fi can be slow is because they can be blocked by interference by other waves crossing them. Additionally, there are certain amount of waves available, so the more devices connected on the wi-fi, the slow the connection will be.
