How Does WIFI work
How Does WIFI work- Have you ever wondered how exactly streaming video or email can be accessed so fast, easily, and in real time on your tablet or smartphone? Wi-fi is being used there. Tech Talker explores the technologies underlying wireless devices this week.
What Is WiFi?
Let’s start by going over some fundamentals. WLAN, which stands for “Wireless Local Area Network,” is the same as WiFi, which stands for “Wireless Fidelity.”
Similar to other wireless technology, WiFi transmits signals between devices using radio waves. When compared to walkie-talkies, vehicle radios, cell phones, and weather radios, the radio frequencies are radically different. In contrast to WiFi, which transmits and receives data as in Gigahertz range, your car audio, for instance, receives frequencies in the Kilohertz as well as Megahertz range (AM and FM stations).

Even more simply put, a Hertz (Hz) is a frequency measurement unit. Imagine that you are watching the waves crest while perched on a pier. The peak of each wave may be seen as you glance down at the waves. The frequency of the waves can be determined by counting the number of secs between each wave crest. The frequency of the wave would therefore be 1 hertz, or one cycle per sec, if the interval between each peak was 1 sec.
When compared to sea waves, Mhz as well as Ghz move through the air at 1 million as well as 1 billion cycles per second! Your radio receiver also needs to be tuned to a specific frequency if you want to be able to hear the information carried by these waves.
This frequency occurs to be 2.4 and 5 GHz for WiFi. The frequency of these waves is extremely similar to that of your microwave. While your network uses 2.412 GHz to 2.472 GHz to send data over WiFi, your microwave uses 2.450 GHz to heat food. This is why some users who attempt to make popcorn in outdated or malfunctioning microwaves encounter a WiFi signal issue.
Just to dispel a common misunderstanding, these microwaves do not emit ionising radiation. As a result, they cannot cause cancer. Yes, microwaves won’t turn you radioactive and shine in the dark.

People May Ask
How does WiFi get internet?
Instead of using cables, a wireless or WiFi network connects your devices, including computers, printers, and cellphones, to the Internet and one another. Within a given range in all directions, any wirelessly capable device, including a laptop or tablet, can obtain the WiFi signal.
Do I need a landline for WiFi?
Simply sign up with a provider that offers residential internet service using a cable, fibre, fixed wireless, satellite, or 5G network. All of these connections don’t need a phone line running into your house.
Can you get rid of landline and keep internet?
Broadband only enables you to have the broadband you want without the landline you don’t use if you don’t use your landline phone. On your landline phone, however, you won’t be able to place or accept any incoming calls. Calls to the emergency services are included in this.
Who has the fastest WiFi?
The fastest internet service provider in the country is Google Fiber, which consistently offers its clients the fastest average speeds. The fibre provider receives an integrated speed score (ISS) of 185.2 with advertised maximum speeds of up to 2,000 Mbps and 12-month average download speeds of 167.1 Mbps.
How fast should my internet be?
It is advised to use 25 Mbps while using four or more devices. A good internet speed of 12 to 25 Mbps makes the most sense for two or more users who frequently stream high definition or 4K video, utilize videoconferencing, play online games, or work from home.
