Who Invented WiFi?

The Great Hawaiin islands were connected in 1971 by a wireless network known as ALOHAnet. That's where Ethernet and WiFi have some of their historical roots.

However, the forerunner to WiFi, known as WaveLAN, was developed in 1991 as a means of connecting cash registers by NCR Corporation, a business that started as a cash register company, and AT&T, a company that started as a phone company.

The Institute of Electrical and Electronics Engineers (IEEE) finally developed the 802.11 standard, which is now known as WiFi, as a result of its widespread popularity. To manage the WiFi trademark, the WiFi Alliance was established in 1999 as a trade association.

How Does WiFi Work? 

WiFi networks use radio waves, a type of electromagnetic radiation with wavelengths, to transport data over the air.

The frequency of WiFi radio waves is usually 2.4 GHz or 5 GHz. These two WiFi frequency bands include different channels. 

When you download a file over a WiFi network, a wireless router gets the data from the Internet via your broadband Internet connection and converts it to radio waves. 

The wireless router broadcasts the radio waves to the surrounding area, captured and decoded by the wireless device that originated the download request.
