WiFi (Wireless Fidelity) is a wireless network protocol that devices use to communicate without a direct cable connection. This technology represents a type of wireless local area network (WLAN) protocol based on the IEEE 802.11 standards. Wlan  bacobolts

Networks allow computers to connect through wireless radio connections by sharing data and accessing external networks. You can connect multiple enabled devices that are within range of the WLAN. Simply put, WiFi is access to the Internet from a wireless-capable device.

like a phone, tablet or laptop. Most modern devices support WiFi, allowing you to join a network and thus access the Internet and share resources.

How does WiFi technology work?

It's like listening to the radio, but both ways. Instead of just receiving sound like we do with AM (amplitude modulation) or FM (frequency modulation) wavelengths, WiFi also allows you to send data, such as an email or social media post.

WiFi sends data over radio waves quickly and reliably so that whatever you are trying to do, the video you want to stream or the game you are going to play, it runs smoothly for you.

WiFi works on radio frequencies of 2.4 GHz and 5 GHz (if you see a wireless network with the number 5 at the end). Think of these numbers as setting your car stereo to 91.0 FM to listen to your favorite music station. Except you don't really need to configure anything. Your WiFi router decides which radio station to put your device on so you can watch YouTube videos on your smartphone or make a video call while on the go.

5 GHz WiFi is more optimal for devices that need a higher connection speed, while 2.4 GHz will be ideal for devices where the range or coverage is greater.

There can be multiple WiFi networks on the same frequencies, so you can see your neighbors' networks when you try to connect your device.

Your WiFi network can slow down at times. If you have multiple Wi-Fi networks running at the same time in the same area, they all use the same frequency ranges.

Also, some parts of your home may have a better WiFi signal. 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.

Placing the router in the correct location can help you dramatically improve your signal range. Try to place it in the center of the area you want to cover and try to make it an area free of obstacles to get the maximum range.

If that is not enough, you can choose to buy a WiFi repeater, a CPL (Power Line Communication) or a Mesh system to improve the coverage of your network throughout the house.

 

Advantages and disadvantages of wireless networks.

 

One of the main advantages is the ease with which they allow people to share information.

The most important advantage of using WiFi is the ability to use the Internet connection to connect to various services. These services include television, broadband Internet access, Bluetooth, and VoIP, among others.

 

Advantage

 

Accessibility - Wireless technology does not require cables so users can communicate even when they are on the go.

Flexibility - Allows users to do their work productively even when they are away from their desks.

Cost-effective - Wireless networks are cost-effective solutions because they are easy to install and inexpensive.

Greater opportunities: with its use, companies can introduce new products and / or services to the market. Many train stations, cafes, airports, and hotel waiting rooms have installed WiFi services so you can connect your devices on the go.
