What is Wi-Fi? – Uses, Types, How does Work, and More

What is Wi-Fi?

Wi-Fi (derived from the Wi-Fi product) a telecommunications technology.

It lets wireless interconnection between computers and electronic systems, such as computers, video game cabinets, televisions, cell phones, players, pointers, and so on.

What are the Uses of Wi-Fi?

Wi-Fi is used to connect plans or an Internet access opinion over short distances, in-home, inside a vehicle, or on each minor building floor.

Thus, cables and other devices distribute with since it is enough that each computer or device has a receiving antenna and has the safety password to access the point.

In this way, local networks can also conveniently establish, and information can even share between dissimilar types of plans, such as cell phones, televisions, and computers.

Types of Wi-Fi


Different kinds of Wi-Fi are known, rendering to the standards they use for their identification, and that can distinguish into two categories:

1. 2.4 GHz Band

  • Now are the IEEE 802.11b, IEEE 802.11g, and IEEE 802.11n standards, whose management is global and lets hurry of 11 Mbit / s, 54 Mbit / s 300 Mbit / s, correspondingly.
  • However, it is the kind that sums the most meddling since Bluetooth and other wireless systems also use the 2.4 GHz band.

2. 5GHz Band

  • The new type of Wi-Fi, known as WIFI 5, applies the IEEE 802.11ac standard and handles an utterly new channel that allows for interference.
  • So, despite the existence of new technology and having difficulty 10% Less throw coldness, it is incredibly convenient, given its constancy and speed.

How does Wi-Fi Work?

  • The modem sends it to decipher signal to a router, and this way, it transmits radio waves.
  • Wi-Fi operates in a much similar way as cell phones or radio transmitters. Initially, the information on an Ethernet connection decodes by an ordinary modem, which transmits. Its deciphered sign to a wireless router or router, which directs it as radio waves around it.
  • In many cases, both devices previously contain one device, which fulfils both functions: it gets the broadband sign and interprets it as radio breakers.
  • Then, the Wi-Fi device on our computer or cell phone, to quote an instance, interprets these radio signals and vicissitudes them into data again.
  • The cycle then recurrences itself when our device directs in its place of receiving information, and so on and simultaneously.

How does Wi-Fi Connectivity Work?


  1. The  Wi-Fi dishonourable on radio waves, just like the radio itself, mobile phone, or television. Therefore, Wi-Fi networks transmit info over the air using radio waves.
  2. However, the incidences cast-off for this wireless connectivity technology are dissimilar, specifically 2.4 GHz up to the 802.11 n normal and  5 GHz in  802.11 ac.
  3. Although 5 GHz delivers superior performance, both frequencies use. And, also, in higher performance equipment, data transmission on both bands is combined.
  4. Therefore, when we download a file or appeal certain information through a Wi-Fi network, our router obtains the Internet through our connection and later changes it into radio waves.
  5. In this way, the router releases these waves, and the wireless device that has requested the download of that file or info captures and decodes them.
  6. These waves can be interrupted by specific interferences caused by other Wi-Fi networks or dissimilar electronic plans such as microwave ovens, refrigerators, televisions, or battery telephones.
  7. Hence, we always claim on analyzing where we will home our router at home to have the best possible wireless connection and evade specific interferences.

What is a Wi-Fi Access Point?

  • An access opinion is an area with wireless connectivity over this technology. This area or admission point makes a local wireless network (WLAN) to connect from other devices.
  • Our router is a Wi-Fi access point, for example, as extended as it has this technology. And community networks in coffee shops, airports, and other formations are too.
  • However, a wide diversity of wireless network connecters can share Wi-Fi connect to another network that allows them access to the Internet.
  • Smartphones can advantage wireless connectivity with mobile networks in this way. And, therefore, we can share Wi-Fi with Android and iPhone.

Advantages and Disadvantages of Wi-Fi Networks

Wireless connectivity is becoming wider and wider, and it has undoubtedly made our life completely changed.

We live in a technological age, predominant that we live connected. That is mostly due to the significant number of Wi-Fi connections that we can access wherever we go.

However, although these categories of connections proposal certain compensations, we container also find certain disadvantages.

Among the main compensations that WIFI proposals us, it is worth stress:

1. Wireless Connectivity

  • One of the main compensations that Wi-Fi offers us is that it is a type of wireless connectivity.
  • Therefore, cables’ physical joining is unnecessary, so we avoid filling our house or office with all flanks’ appearances.

2. Convenience

  • The part that it is wireless connectivity does not provide the proposal of great ease and freedom.
  • That is, we can drive from one home to another with our processer, tablet, or mobile and continue connected deprived of this affectation any problem.
  • The range is typically more than sufficient in most homes, although there are numerous options to spread the Wi-Fi range if necessary.

3. Cost

  • Not having to usage wiring and devices makes a Wi-Fi net have a much lower charge than wired networks.

4. Compatibility

  • The Wi-Fi Alliance safeguards full compatibility between devices. Therefore, it lets us use Wi-Fi technology with full compatibility wherever in the world.

5. Speed

  • Numerous factors can touch our relationship’s speed in the relationship’s device in using a Wi-Fi connection. The cable is much less likely if we use overstated detachments or short lines excellence.

6. Latency

  • It is additional of the main problems that we can discover in this type of wireless connection.
  • Wi-Fi connections are more disposed to certain lags, especially when we want to stream high-resolution hypermedia content or play online.
  • Also, some individual external go-betweens can negatively affect our connection in this way.

7. Interferences

  • Wi-Fi networks can be affected by specific interferences, which will mean a lower presentation of them.
  • Specific electronic plans and appliances can generate waves that delay with those of this kind of wireless network. Still, certain rudiments such as walls or doors can also cause the sign to reach certain house corners.

8. Micro- Cuts

  • These aspects that can negatively influence a Wi-Fi network can cause individual cuts in our connection. On certain occasions, they may not touch what we are doing, but it can be problematic in some instances.


We can appreciate an examination of traffic and clients connected to the Wi-Fi network in this previous one with detailed graphs. Again, we are talking about professional-oriented purposes.

In any case, the selection proposed by TP-Link is reminiscent of Google software, another exciting opportunity for managing a wireless network.
