It is a network that works wirelessly and shares the internet , connecting multiple devices through a router. It is not necessary to use a cable or connectors in our cell phones, for example, since it works through radio waves. These allow electronic devices easier handling. In this way, a device does not need to be attached to the router.
The WIFI network is characterized by its easy access, because it allows us to communicate in different applications and offers us security and privacy. Knowledge of network operating systems is essential . Now a wireless network adapter is frequently used in order to connect and favor your computer to the network.
The components of the WIFI are what give it a good operation, allowing to change and improve the performance in each device. Next, you will be able to understand in more detail what WiFi networks are about and what they have to do with this topic.

What is a Wi-Fi network?
It is a type of wireless network that works in order to reach the internet connection on mobile devices, making our coverage with the web more efficient and durable.
The WIFI network is controlled in different ways and from various devices, and in some cases it can change its management, depending on the place where it is located. The WIFI amplifier or adapter is a device that is used to reasonably improve and change your coverage at home .
Who invented the technology of WiFi networks?
Hedy Lamarr and her partner George Antheil together came up with frequency hopping. This technology was the initiator of the first Wi-Fi connection standard . Before this advanced radio wave transmission system came into existence , many steps were taken to achieve the result we enjoy today.
It has been studied that the technology appeared due to the need to implement a type of wireless connection mechanism that would be compatible with different devices.
In 1999 some companies came together to create the Wireless Ethernet Compatibility Alliance , today called WIFI. The objective of this was to design a brand that would agree to promote wireless science and strengthen the unity of the team.
What are Wireless standards?
The model 802.11 family of wireless standards. It was originated by the Institute of Electrical Engineers (IEEE) . The superior mode of calling such WIFI technology is 802.11 e.
It grew from earlier versions of wireless with multiple radios, advanced receiving and transmitting techniques, and the right to use the 5 GHz spectrum.
This IEEE 802.11 standard was designed to supplant the equivalent physical and MAC layers. An 802.11 wireless local area network supports all local area network (LAN) services .
What are the fundamental elements of a WiFi network?
The crucial and necessary elements to build an educational or home WiFi network are the following.
- Router
- Modem
- Extensor de red
- Switch de red
Among all the elements, the most important of any network is the router , since it is the one that provides connection to all our devices. The other devices will be necessary or not depending on the function of characteristics and particularities.
Access point
It is a type of device that generates a wireless local area WLAN network. The WLAN network can also switch and connect various types of computers to a central information system. An access point is used to connect to the router through an Ethernet cable, projecting a WIFI signal in a certain area.
Through radio waves, the signal reaches our equipment without the need to be so close to the marker. The switch is the type of digital device that is responsible for the interconnection of equipment in a single network, thus forming the local area network LAN.
Providing a certain movement in networks, which avoids the use of cables that are difficult to connect. WLAN allows switching to improve data communications.
wireless bridge
They are a way for your wireless router to connect to a secondary access point . Its function allows to extend the scope of the broadcast network.
A bridge joins network fragments composing a single subnet. It works by means of a table of MAC addresses displayed on each segment to which it connects.
Router
The router is a device that offers a WIFI connection linked to a modem. It is an element that allows interconnecting networks with different prefixes in its IP address, thus being the most necessary piece because through it the LAN network is assembled.
It is a device that sends information from the Internet to personal computers . It establishes the most favorable route for each data packet in order to improve and reach the network. Reinforcing the security of our router is always important, just as knowing the IP address of our router is essential, knowing what type of networks it connects to, since in this way, the signal will have much more speed or coverage.
When choosing a router we must take into account which one we can choose. There are two bands, between the two, the 5 GHz offers up to 2,167 Mbps each, however, its disadvantage is that it has 4 antennas instead of 8. There is also another band model, the 2.4 GHz, which is the frequency of radio. There are so far five types of router based on their application. Wired, wireless, core, edge, and VPN. This equipment is a valuable element to have a WIFI network.
