How Wi-Fi actually Works?

Do you ever wonder how you can connect to your Wi-Fi router and start streaming Youtube videos with just a few touches on your mobile phone? More than 4,000 people want answer to this question every month.

It’s very easy to understand. In this article, I will try to explain you the same thing in a best possible way. First of all, let me make it clear that Wi-Fi does not mean internet connection. It is because, when we think about Wi-Fi, we think about accessing the internet.

You can also create Wi-Fi network with 4-5 connected devices to share information without using internet connection. Also, You can create Wi-Fi network to play games with your friends in the same room without the internet connection.

So, Wi-Fi (also known as Wireless fidelity) does not mean internet connection. The Wi-Fi is a technology that uses radio signals to provide network connectivity not only the internet but also with the other devices in the same Wi-Fi network.

When your Wi-Fi router is properly configured and the hotspot is active, it will provide wireless connectivity to other devices by emitting frequencies between 2.4GHz to 5GHz based on the usage of the network.

You can customize your Wi-Fi network and make it more secure by accessing from your browser.

Like cellular phones, a WiFi system uses radio waves to transmit data across a system. The pc must include a wireless adapter which will interpret data sent to your wireless signal. The exact same signal is going to be sent, through an antenna, into some decoder referred to as the router. Once deciphered, the information will be transmitted into the Internet via a wired Ethernet link.


Since the wireless system functions as a two-way site traffic, the information obtained from the net will even pass through the router to be categorized to a radio signal which will be obtained from your computer’s wireless adapter.

Types of frequencies

There are few different types of frequencies used in Wi-Fi. Here are they:

The 802.11a will transmit data in a frequency level of 5GHz. The Orthogonal Frequency-Division Multiplexing (OFDM) used enhances reception by dividing the radio signals into smaller signs before hitting the router. You may transmit a maximum of 54 megabits of information per minute.

Even the 802.11b will transmit information in an increased amount of 2.4GHz, and it can be a relatively slow rate. You may transmit a maximum of 11 megabits of data per minute.

The 802.11gram will transmit data at 2.4GHz but has the potential to transmit a maximum of 54 megabits of information per minute as it also uses an OFDM coding.

The more innovative 802.11n can transmit a maximum of 140 megabits of information per second and uses a frequency level of 5GHz.


So, this is how basically Wi-Fi works. If you have questions regarding this, you can comment them down in the comment section and we will help you solve your queries as soon as possible.
