Wi-Fi It's something we arguably all know, but have you ever taken a moment and wondered where it came from? In 2019, our dear and beloved Wi-Fi turns 20 and this date cannot be left blank. 1a4om
In this special, we tell you a little about the origin story of this invention that today connects us and surrounds us wherever we go, and of course, all kinds of Wi-Fi and how it has evolved over the years.
The origin of the unexpected 456kd
In 1999, a company called Wi-Fi Alliance announcement for which he was responsible for selling equipment frequently IEEE 802.11, that is, equipment that used wireless frequencies to exchange data and information.
Over time, the same company noticed that the name “Equipment with IEEE 802.11 frequency and an algorithm for exchanging data” was not such a good name for its product that was already starting to become successful. So they decided to hire a marketing and branding team from Interbrand to help the company decide on a better name for its product.
Wi-Fi devices and adapters
Phil Belanger, one of the founding of the Wi-Fi Alliance announcement was present during his company's product naming selection, and said that the term "Wi-Fi” was used as a joke among colleagues because it sounded similar to the American term “Hi-Fi" what does it mean High Fidelity, a term used to identify and point to top, reliable equipment. And so, the term was born. Wi-Fi!
showing the Ying-Yang, balance and perfection with greatness
Like many products that you can only distinguish by color or branding, the classic Wi-Fi logo is unmistakable anywhere. But do you know what it means?
O ying-yang present not only in the colors but also in the logo of the Wi-Fi, symbolize the interpolation of technology with third-party devices, that is, a complete harmony between them. And that's not some sort of general knowledge, that's facts. O Wi-Fi completes us, surrounds us and connects us every day.
Have you ever stopped to notice how connected you are? Whether through social networks, media, information, news, games, whatever, you are connected wherever you are, and a frequency and responsible for that, the Wi-Fi.
Evolution of Wi-Fi over the years 6sw5h
Just like technology and even development, connection has been adapting and evolving over the years, and wireless connection is no exception to this evolution. Gradually growing and learning from its mistakes, the connection and its algorithm became bigger and bigger, and along with them, its frequency rate and data exchange as well.
Initially in 1997, equipment with the IEEE 802.11 technology and algorithm that is now obsolete, network distribution equipment managed to reach a frequency of 2.4 GHz (gigahertz), which functioned as the frequency range of the Wi-Fi in the zone you were in, varying between 15~20 meters with that frequency and also with a data exchange of 1 to 2 mbp/s (megabits per second), which was considered quite fast for the time.
As previously mentioned, the algorithm has undergone several changes and, of course, everything that changes, evolves. We briefly quote here the evolution of the algorithm Wi-Fi over the years:
- 802.11b (1999) it was the mark of the first change in the algorithm, where it was now able to work with a larger data exchange, going from 1, 2, 5.5, up to 11Mbp/s but keeping the frequency at 2.4Ghz;
- 802.11a (1999) in the same year, changing its data exchange rate to a larger scale, raising it to up to 54Mbp/s. Also counting on a higher frequency rate, reaching 5.5Ghz;
- 802.11g (2003) still maintaining the same standards, the algorithm only increases the range of its transmission rate, thus making it cover up to 38 meters, 18 meters more than initially developed;
- 802.11 (2007) several versions have been released to fix minor problems with connection and data exchange on the wireless network, identified by the letters d,e,g,h,i,j but with little relevance when cataloged. They all ended up unifying and became the version IEEE 802.11-2007 of the algorithm;
- 802.11n (2009) now adding the function of connection and adaptation of multiple antennas in the equipment with the algorithm, the Wi-Fi starts to get stronger. Being able to use rates now of 2.4 and 5.0Ghz on the same device, the algorithm also adapts to a new data exchange, ranging from 72.2 to 150 Mbps/s. Also increasing its maximum range capacity, up to 70 meters;
- 802.11 (2012) as in 2007, this year the versions that corrected minor problems in the previous algorithms were cataloged, named k,r,y,n,w,p,z,v,u,s, all were combined as IEEE 802.11-2012.
- 802.11ac (2013) without modification in its total range, this is the last version already released of the algorithm, which manages to work in different sizes in its data exchange, ranging from 200 Mbps/s with a maximum limit of up to 1.73Gbp/s in some equipment, keeping of course, its 5.0Ghz frequency for all current devices.
This nomenclature of the algorithm, however, was discarded, and in its place the algorithms together received versions accompanied by the name of the technology. Here's how it looks now:
- 802.11b Wi-Fi has become Wi-Fi 1;
- Wi-Fi 802.11a is now Wi-Fi 2;
- Wi-Fi 802.11g turned Wi-Fi 3;
- Wi-Fi 802.11n switched to Wi-Fi 4;
- 802.11ac Wi-Fi is now Wi-Fi 5.
This year 2019 also marks the beginning of the new algorithm that Wi-Fi will start to adopt, being the 802.11ax, which will be called Wi-Fi 6, Despite being new, routers and smartphones are already ed by new technology, such as the LG, Among others.
O Wi-Fi 6 promises to be faster, safer, more economical and also promises to much more connected devices. Coming later this year, the new algorithm should a 9,6GB/s connection and will work on 2,4Ghz and 5Ghz frequencies.
Importance of Wi-Fi in our daily lives 1h426a
Not only to send files or access social networks, the Wi-Fi plays an important role in our daily lives as well as in the technology that surrounds us. Whether it's simply being a vehicle for exchanging data over a wireless network connection and going up to security means as well.
Several companies like Microsoft, Apple , AT&T, Dell and even himself Google use data exchange frequency for security purposes, either in monitoring or for exchanging data from one location to another.
Using the technology of WEP (Wired Equivalent Privacy, equivalent wireless privacy) initially, a security algorithm that allowed the to only connect to the network if he fulfilled the necessary requirements, such as the name of the network itself and, of course, a , which should contain between 10 and 24 digits hexadecimal.
However, in 2003, the Wi-Fi Alliance announcement announced that the security method WEP was obsolete and would be replaced by WPA (Wi-Fi Protected Access, protected access from the wireless network) that started the security system that after a few years became the WPA2 and WPA3, the same security system but in its improved forms. It is generally used by security standards on devices with security functions. Wi-Fi nowadays.
In 2018, a security system called TKIP (Temporal Key Integrity Protocol, something like integration protocol of key security), plus, of course, the default WPA3, which hides the key encryption of the device, thus making the device with the new algorithm and security protocols practically inaccessible through third parties, other than physically.
The net Wi-Fi as much as it is “on the air” and in a way free to go wherever you want, it is as strong as a in your computer's operating system. So don't worry, thanks to Wi-Fi, your data is safe wherever it is and wherever it is sent!
Of course, we also need to mention companies that use frequency and its algorithm to sell their own customized equipment, such as Cisco, D-Link, Ea HP. And obviously we're talking about wireless network transmitters, the Routers.
Routers are devices that have become as commonplace as cell phones or computers but are definitely not getting the attention they deserve. Having an important role in a network environment, these hardwares are responsible for propagating the technology of the Wi-Fi everywhere we go, no matter the size.
Connectivity is the key to growth and Wi-Fi is the bridge that connects us 4w6h3k
for years the Wi-Fi was present in our lives, growing and evolving, just like ourselves. Through connectivity, we connect to each other, we are part of each other's lives and we owe a part of it to him.
Not only does it provide us with a wireless network connection and cutting-edge security that is always evolving, but it also keeps us connected no matter where we are. Whether for exchanging files or data, the Wi-Fi It's everywhere, wherever you go. Congratulations on 20 years!
