What is WiFi and how it works?

Wi-Fi is the wireless technology used to connect computers, tablets, smartphones and other devices to the internet. Wi-Fi is the radio signal sent from a wireless router to a nearby device, which translates the signal into data you can see and use.

How does WiFi work step by step?

WiFi works in three simple steps:

1. The modem needs to have a cable or wired connection to access the internet.
2. The router is connected to the modem.

Does Wi-Fi go through walls?

Wi-Fi signals are most weakened by having to go through thick walls, especially reinforced concrete. See also: Wi-Fi Signal Loss by Building Material.

Is Wi-Fi a microwave?

Wi-Fi transmits data using microwaves, which are high-energy radio waves. Wi-Fi is more complicated than FM radio, but the basic underlying technology is the same.

What is 4×4 WiFi?

Just for background, 4×4 means four transmitters and four receivers, required under the 802.11n standard to get the full 600 Mbps possible. As I have said many times, throughput on wireless isn’t really about throughput – it’s about capacity.

How does Wi-Fi work?

WiFi works off of the same principal as other wireless devices – it uses radio frequencies to send signals between devices. The radio frequencies are completely different say from walky talkies, car radios, cell phones, and weather radios.

What are Wi-Fi’s two frequencies and why do they matter?

That’s where Wi-Fi’s two frequencies, 2.4 gigahertz and 5 gigahertz, come in. Wi-Fi can broadcast on both frequencies, a benefit that helps its signal cut through all the noise and deliver a fast, strong signal from your wireless router to your computer. “Essentially these frequencies are like two different FM radio stations,” says Figueroa.

What is WiFi and WLAN?

First, let’s cover some of the basics. WiFi stands for Wireless Fidelity and is the same thing as saying WLAN which stands for “Wireless Local Area Network.”. WiFi works off of the same principal as other wireless devices – it uses radio frequencies to send signals between devices.

How does a wireless router work?

The router sends the information to the internet using a physical, wired ethernet connection. The process also works in reverse, with the router receiving information from the internet, translating it into a radio signal and sending it to the computer’s wireless adapter.
