What is Wi-Fi?
Wi-Fi (derived from the Wi-Fi brand) a telecommunications technology.
It allows wireless interconnection between computers and electronic systems, such as computers, video game consoles, televisions, cell phones, players, pointers, etc.
What are the Uses of Wi-Fi?
Wi-Fi is used to connect devices or an Internet access point over short distances, in-home, inside a vehicle, or on each small building floor.
Thus, cables and other devices dispense with since it is enough that each computer or device has a getting antenna and has the safety password to access the point.
In this method, local networks can also conveniently establish, and data can even share between different kinds of devices, such as cell phones, televisions, and computers.
What are the Types of Wi-Fi?
Different kinds of Wi-Fi are known, according 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 values, whose handling is international and lets hurry of 11 Mbit / s, 54 Mbit / s 300 Mbit / s, correspondingly.
However, it is the type that totals 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 is handled entirely new channel allowed for interference.
So, despite being a new technology and having difficulty 10% Less throw distance, it is incredibly convenient, given its stability and speed.
How does Wi-Fi Work?
The modem sends it to decode signal to a router, and this way, it transmits radio waves.
Wi-Fi operates in much the same way as cell phones or radio transmitters. Initially, the information on an Ethernet connection is decoded by an ordinary modem, which transmits its signal to a wireless router or router, which sends it as radio waves around it.
In many cases, both devices previously consist of one device, which fulfills both functions: it obtains the broadband sign and interprets it as radio rollers.
Then, the Wi-Fi device on our computer or cell phone, to cite an example, interprets these radio signals and changes them into data again.
The cycle then repeats itself when our device sends in its place of receiving information, and so on and simultaneously.
How does Wi-Fi Connectivity Work?
The Wi-Fi base on radio waves, just like the radio itself, mobile phone, or television. Therefore, Wi-Fi networks transmit information over the air using radio waves.
However, the incidences used for this wireless connectivity technology are dissimilar, specifically 2.4 GHz up to the 802.11 n standard and 5 GHz in 802.11 ac.
Although 5 GHz provides superior performance, both frequencies use, and, also, in higher performance equipment, data transfer on both bands is combined.
Therefore, when we download a file or request certain information through a WiFi network, our router receives the Internet through our connection and later converts it into radio waves.
In this way, the router emits these waves, and the wireless device that has requested the download of that file or information captures and decodes them.
These waves can interrupt by specific interferences caused by other WiFi networks or by different electronic devices such as microwave ovens, refrigerators, televisions, or cordless telephones.
Hence, we always insist on analyzing where we will place our router at home to have the best possible wireless connection and avoid specific interferences.
Access Point of Wi-Fi
An access point is an area with wireless connectivity finished this technology. This area or access point creates a local wireless network (WLAN) to connect from other devices.
Our router is a WiFi access point, for example, as long as it has this technology. And public networks in coffee shops, airports, and other establishments are too.
However, a wide diversity of wireless network adapters can share WiFi connect to another network that allows them access to the Internet.
Smartphones can benefit from wireless connectivity with mobile networks in this way. And, therefore, we can share WiFi with Android and iPhone.
Advantages and Disadvantages of Wi-Fi Networks
Wireless connectivity is becoming more and more extensive, and it has undoubtedly made our life completely changed.
We live in a technological age prevalent that we live connected. It is mostly due to the significant number of WiFi connections that we can access wherever we go. However, although these categories of connections offer certain compensations, we can also find sure disadvantages.
Among the main advantages that WIFI proposals us, it is worth stress:
1. Wireless Connectivity
One of the main compensations that WiFi offers us is that it is a type of wireless connectivity.
Therefore, cables’ physical connection is unnecessary, so we avoid filling our house or office with lines from all flanks.
The detail that it is wireless connectivity does not support the proposal of great ease and freedom.
That is, we can drive from one place to another with our processer, tablet, or mobile. And continue connected deprived of this posing any problem.
The range is usually more than sufficient in most homes. However, there are numerous options to spread the WiFi range if necessary.
Not having to use wiring and devices makes a WiFi net have a much lower charge than wired networks.
The WiFi Alliance safeguards full compatibility between devices. Therefore, it lets us use WiFi technology with full compatibility wherever in the world.
Numerous factors can affect our relationship’s speed in the relationship’s device in using a WiFi connection. The cable is much less likely unless we use overstated distances or short lines quality.
It is another of the main problems that we can find in this type of wireless connection. WiFi connections are more disposed to certain lags, especially when we want to stream high-resolution hypermedia content or play online.
Also, some individual external agents can negatively affect our connection in this way.
WiFi networks can affect by specific interferences, which will mean a lower performance of them.
Specific electronic devices and appliances can generate waves that interfere with those of this type of wireless network. Still, certain elements such as walls or doors can also cause the signal to reach certain house corners.
8. Micro- Cuts
All these types of aspects that can negatively influence a WiFi network can cause individual cuts in our connection.
On certain occasions, they may not affect what we are doing, but it can be a big problem in some instances.
We can appreciate an analysis of traffic and clients connected to the WiFi network in this previous one with detailed graphs. Again, we are talking about professional-oriented functions.
In any case, the option proposed by TP-Link is reminiscent of Google software, another exciting opportunity for managing a wireless network.
