WiFi (Wireless Fidelity) is a wireless network protocol that
devices use to communicate without direct wired connections. This technology is
a type of wireless local area network (WLAN) protocol based on the IEEE 802.11
standards. Wlan Marketingmediaweb
Networks allow computers to connect through wireless radio
connections exchanging data and accessing external networks. You can connect
multiple devices that are turned on and within range of the WLAN. In short,
Wi-Fi is accessing the Internet from a wireless device.
like a phone, tablet or laptop. Most modern devices support
Wi-Fi, allowing you to connect to the network and thus access the Internet and
share resources Divinebeautytips

How does Wi-Fi technology work?
It's like listening to the radio, but with two-way traffic.
Instead of just receiving sound, as we do with AM (amplitude modulation) or FM
(frequency modulation) wavelengths, WiFi also allows you to send data, such as
emails or social media messages.
Wi-Fi transmits data over radio waves quickly and reliably,
so what you're trying to do, the video you want to stream, or the game you're
about to play, is transparent to you.
WiFi works on radio frequencies of 2.4 and 5 GHz (if you see
a wireless network with a 5 at the end). Think of these numbers as tuning your
car radio to 91.0FM to listen to your favorite music station. Except you don't
really need to configure anything. Your WiFi router decides which radio to set
your device so you can watch YouTube videos on your smartphone or make video
calls while on the go.

The 5 GHz Wi-Fi connection is best for devices that require
faster connection speeds, while the 2.4 GHz is ideal for those devices that
require range or coverage.
There can be multiple Wi-Fi networks on the same
frequencies, so you can see your neighbors' networks when you try to connect
your device.
Your Wi-Fi network may be slower at times. If you have
multiple Wi-Fi networks operating simultaneously in the same area, they all use
the same frequency bands.
Also, in some parts of your home, the Wi-Fi signal may be
better. It depends on the router. A single router is like a light bulb in the
sense that one light bulb has a limited light range and a router has a limited
signal range. Nanobiztech
Placing your router in the right place can help you
dramatically improve your signal range. Try to place it in the center of the
area you are going to cover and try to make it clear to get the maximum range.
If that's not enough, you can purchase a WiFi repeater, PLC
(power line communication), or mesh system to improve your network coverage
throughout your home.
Advantages and disadvantages of wireless networks
One of the main benefits is the ease with which they allow
people to share information.
The most important benefit of using Wi-Fi is the ability to
use your Internet connection to connect to various services. These services
include, but are not limited to, television, high-speed Internet access,
Bluetooth, and VoIP.
Advantage
Accessibility - No cables are required for wireless
technology, so users can communicate even on the go.
Flexibility: allows users to do their work efficiently, even
when they are out of the office.
Cost-effective - Wireless networks are cost-effective
because they are easy to install and inexpensive.
Great opportunities: with its use, companies can bring new
products and / or services to the market. Many train stations, cafes, airport
lounges, and hotels have Wi-Fi services so you can connect your devices on the
go.
