Today it is difficult to imagine our life without the Internet.
It helps you find any information, video or audio in seconds at work, at home, in public, while traveling. Wi-Fi, which works on the basis of radio waves, is one of the most common technologies in the world and is used in smartphones, laptops, televisions, video surveillance systems and a number of other places, and it allows you to move freely and connect many devices at the same time.
Wi-Fi technology first
It is called "IEEE 802.11". This is the first protocol that served to launch the wireless Internet. In 1999, Interbrand proposed to name the technology as "Wi-Fi", which is easy to pronounce.
* Wi-Fi logo is the official logo based on the In-Yan symbol. It is a symbol of compatibility of all devices that support the technology.
* Wi-Fi actually originated in Hawaii. An innovative computer network called ALOHAnet has been created at the University of Hawaii. With its help, in 1971, the first public demonstration of wireless transmission of packet data was held. 20 years later, WaveLAN technology was discovered by NCR and AT&T corporations. In 1997, the first version of IEEE 802.11(+r) wireless protocol was presented.
* At that time, the "farthest" Wi-Fi signal was transmitted at a distance of 420 meters. With the help of 6-watt amplifiers, the Swedish Space Agency managed to transmit information to a space probe located at a distance of more than 400 meters.
