How WiFi Technology Works | Wireless Communication Explained

In this video, We will Discover how wifi and wireless communication actually works.
I am not going to talk history here, everything history related is mentioned in the video.
Basically, WiFi works because of radio waves signals, sent and receives by devices. Our Phones can send radio waves signals to the router, WHY? because they are wifi enabled devices, or devices capable of sending and receiving radio wave signals and converting these signals to machine language or binary, then converting this data to meaningful information for the user.
How does this process works? Basically, if you send a message to your friend, your phone will first convert Your "Hello Friend" Message to binary, then this data will be added to a radio wave signal, This process is called modulation. Once added to the radio wave signal, it will be transmitted into thin air and will be captured by your router's antenna. The router demodulates the signal and using TCP/IP protocol, to send data to the receiver.
WiFi bandwidth like 2.4GHZ and 5GHZ vary in terms of distance, interference and speed. A 2.4 GHZ frequency band is more likely to interfere with objects like microwaves then 5GHZ, because these machines also use 2.4GHZ. However 5GHZ Have shorter distance compared to 2.4 GHZ because they tend to interfere more with objects like Walls.
