When was wifi discovered?
"The precursor to Wi-Fi was invented in 1991 by NCR
Corporation/AT&T (later Lucent & Agere Systems) in
Nieuwegein, the Netherlands. It was initially intended for cashier
systems; the first wireless products were brought on the market
under the name WaveLAN with speeds of 1 Mbit/s to 2 Mbit/s. Vic
Hayes, who held the chair of IEEE 802.11 for 10 years and has been
named the 'father of Wi-Fi,' was involved in designing standards
such as IEEE 802.11b, and 802.11a."
So, Vic Hayes was the "main guy." As for when...?
