High technology has become a part of everyday life. Wireless Internet, which previously could only be dreamed of, is now commonplace and commonplace. Rarely does anyone have questions about the principle of a wireless connection or how the abbreviation Wi-Fi stands and what it means.
What is Wi-Fi
Wi-Fi is a trademark of the Wi-Fi Alliance for wireless networking. The abbreviation Wi-Fi itself was derived from the English phrase "Wireless Fidelity", which literally means "wireless quality" or "wireless accuracy" and was used for advertising purposes to draw attention to the new product. At the moment, this wording has been abandoned, and now "Wi-Fi" is not decrypted in any way.
Today, under the Wi-Fi Alliance trademark, many standards for the transmission of digital streams are being developed.
Wi-Fi was established in 1991 in the city of Nieuwegein, the Netherlands. Its creator, Vic Hayes, was then at NCR Corporation / AT&T, later renamed Agere Systems.
Initially, Wi-Fi was developed for checkout systems in stores and provided information transfer at a speed of 1 to 2 Mbps.
The standard in which the Wi-Fi connection works is called IEEE 802.11n. In 2009, it was officially approved. The use of Wi-Fi has made it possible to transfer data up to four times faster than devices operating in earlier standards. In theory, the IEEE 802.11n standard is capable of delivering data rates up to 600 Mbps.
Benefits of Wi-Fi
Wi-Fi is a very convenient way to transfer data because it has a number of advantages. One of them is the absence of cables, which significantly reduces the cost of network deployment. In addition, it provides Internet access in places where it is prohibited to lay cables, for example, in places of historical value.
Based on the same lack of wires, the user is no longer tied to one Internet access point. Wi-Fi also allows mobile devices to access the network.
Given the wide coverage of one Wi-Fi point, it should be mentioned that within the Wi-Fi zone, several users can access the Internet at once from computers, laptops and phones.
In addition, at the time of Wi-Fi data transmission, devices emit radiation 10 times lower than cell phones.
Well, since today Wi-Fi devices are widespread in the market, there is a guarantee of compatibility between any equipment marked with the Wi-Fi logo. This became possible due to the mandatory certification of devices working with the specified data transfer standard.
