They are the ones credited with inventing Wi-Fi. The first wireless products were under the name WaveLAN. In 1991, NCR Corporation with AT&T Corporation invented the precursor to 802.11, intended for use in cashier systems. These frequency bands are the same ones used by equipment such as microwave ovens and are subject to interference. Federal Communications Commission released the ISM band for unlicensed use – these are frequencies in the 2.4GHz band. Vic Hayes is often regarded as the “father of Wi-Fi.” He started such work in 1974 when he joined NCR Corp., now part of semiconductor components maker Agere Systems.Ī 1985 ruling by the U.S. ALOHAnet and the ALOHA protocol were early forerunners to Ethernet, and later the IEEE 802.11 protocols, respectively. In 1971, ALOHAnet connected the Hawaiian Islands with a UHF wireless packet network. The history of WiFi is long and interesting.
