The modernization of society has led us to use digital media as tools to interact, work and carry out banking or institutional activities. In turn, smartphones are capable of serving as tools for fast transactions… But are they enough? No, they must have an Internet connection in order to have access to the online spaces.
What is a Wi-Fi Network? What are its Characteristics, Components and How it Works?
That is why the need for latent connectivity has arisen; becoming obsolete the keys and the system that operates through a central source typical of LAN networks. So, and as a result of a way of life that handles the web environment as the core of all operations, access to it regardless of geographic location led to the creation of a wireless line that transmits the Internet … Exactly, the WiFi Do you want know more?

What is a WiFi network and what are its main characteristics?
Wireless Fidelity , or also known in its abbreviation as WiFi, is a type of wireless connection that uses radio frequency to make data communication possible. In this case, its objective is to provide a type of signal to various devices, which are in spaces close to a device that generates the access (distances that vary depending on the reception of the device).
- They are individual networksthat have an access limit.
- It can be private free of intruders,but it will also be possible to generate a general public network that is enabled for certain geographical areas.
- It is created under a type of IEEE 802.11 computer systemthat establishes communication based on electromagnetic waves, which remain available at a specific distance; which depending on the type of wireless network may be higher or lower.
- It works through a hotspot, providing the signal depending on the number of antennas it has and the type of band it uses; which will inevitably generate the coverage radius.
- Its objective is to allow users who use its network to access the Internetfrom cell phones, Smart TVs , computers or others; and can communicate without the need to use any wiring.
- To enter , you must enter your PIN, if you have one, and you will immediately be part of an information exchange system.
- It is the way to replace mobile data as Internet generators; which makes you dispense with the telephone companies to navigate, if one of these networks is being actively used.
- Those who have devices that handle the Wi-Fi optionin their configuration as a way to access cyberspace may choose to connect to a Wi-Fi network .
What are the components that allow the operation of a WiFi network?
As we have already mentioned, these waves need a device that acts as the center where the data transmission takes place ; however, it is not a single piece of equipment that operates independently, but rather requires a set of accessories that together make up the Wi-Fi assembly:
- Access points:It is a type of equipment or network service, which supports a WLAN system from which different computers and equipment are connected; regardless of whether they are wired or wireless. This is the source that makes it possible to relate a computer and the components that follow.
- Routers or Router: It serves as the best known part, since it is the center of operations; and one that emits electromagnetic or infrared waves. Also, it is to this device that users connect to be able to establish wireless communication.
- Modem: Another fundamental product is this, since it is what produces the Internet (it can be a cell phone as a modem or a computer connected to a data line). Previously, both computers were independent and connected to each other to work; but currently they are integrated: You usually buy modems with routers when you hire companies that provide these services.
- Adapters: They are responsible for expanding the signal, adding antennas with greater reception or serving as a second router so that the connection expands in other nearby areas: Depending on the case, they will be necessary.
It is through this set of elements that the synchronization of the Internet occurs, the wireless mechanism and the source that makes the operation of both possible. With all this operating, you will only have to access and navigate.
