Big picture

Time period Development summary
<1997 Pre-Wi-Fi era
1997 Wi-Fi is introduced when a committee called IEEE 802.11 is set up.[1][2]
1999 1st generation: The 802.11a standard is released.[3][4] The release of routers sparks the beginning of the wide use of Wi-Fi in homes.
1999 2nd generation: The 802.11b standard is released, facilitating the first widespread implementation of WLAN technology.[5][6] 802.11b features wireless speeds of 11 Mbps.[7]
2003 3rd generation: Faster speeds and distance coverage of earlier versions combine to make the 802.11g standard. Routers get better, with higher power and further coverage.[2][8] 802.11g lets consumers stream music at 54 Mbps.[7]
2009 4th generation: The 802.11n standard is released.[5][9] Faster and more reliable than before, it is built with more antennas and multiple streams of data.[2]
2013 Wi-Fi significantly improves with the emergence of the 802.11ac standard, which packs almost triple the speed of its predecessor, 802.11n. 802.11ac breaks the gigabit per second barrier.[7][10]
2015 Wi-Fi accelerates once again with the MU-MIMO standard.[7]

Year Month and date Event type Details
1941 Technology A spread spectrum technology is patented by composer George Antheil and actress Hedy Lamarr for use in guiding naval torpedoes. It consists in a signal which is spread over multiple frequencies in order to reduce interference. Spread spectrum improves wireless signals, however it does not resolve all interference.[11]
1971 Technology The University of Hawaii, led by engineer and computer scientist Norman Abramson, completes the first wireless data packet transfer ever attempted without a satellite or connected cables, using a new technology called Ultra High Frequency radio waves (UHF) to successfully connect seven computers, spread across different Hawaiian islands.[12]
1985 October 15 Technology IBM introduces Token Ring LAN, running at 4 Mbps.[13][14]
1985 Network The Federal Communications Commission (FCC), the telecoms regulator in the United States, opens the wireless frequencies 900Mhz, 2.4Ghz, and 5.8Ghz to be used without the need for a government license. These radio bands are used by household appliances such as microwaves, and are assumed to have no practical application in communications due to interference.[15][11][12]
1987 Security American cryptographer Ron Rivest working at RSA Security develops the RC4 Cipher, a security cipher (Key size: 40-2048 bits).[16]
1988 The NCR Corporation, in hopes of adopting a wireless local area network (WLAN) standard for use in their wireless cash registers, turns to Victor Hayes, author of many of their data transfer standards, who, along with Bell Labs engineer Bruce Tuch, ask the Institute of Electrical and Electronic Engineers (IEEE) for assistance in utilizing these frequencies for a WLAN standard. A committee is created with the catchy title “802.11”. The standard would be published nine years later, named after the committee, and Victor Hayes would be called the "father of Wi-Fi".[11][14]
1989 The NCR Corporation submits the WaveLAN design (a brand name for a family of wireless networking technology) to the IEEE (​Institute of Electrical and Electronics Engineers)​ 802 LAN/MAN Standards Committee.[14]

1993 ​Henrik Sjödin proposes the creation of publicly accessible local area networks (LANs) at the NetWorld+Interop conference in The Moscone Center in San Francisco. While Sjödin does not use the term “hotspot”, this is considered the first mention of the concept.[14][17]
1994 Carnegie Mellon University begins installing the first campus-wide wireless network.[12] The largescale installation is completed by AT&T.[14]
1994 Carnegie Mellon University builds the first campus-wide wireless Internet network, "Wireless Andrew" (named for university benefactors Andrew Carnegie and Andrew Mellon).[14] Started as a National Science Foundation-funded research network to support Carnegie Mellon's wireless research initiative, Wireless Andrew originally provides coverage in seven campus buildings. In 1999, it would expand to serve all 65 residential, academic and administrative buildings on the campus — covering approximately 3 million square feet as well as outside areas.[18]
1996 Technology Australian electrical engineer John O'Sullivan, working at the Australia’s Commonwealth Scientific and Industrial Research Organization (CSIRO), develops a technique for reducing multipath interference of radio signals transmitted for computer networking. This technique would eventually find its way into the 802.11a (and later) standards.[14][19][20]
1997 Wi-Fi is first released for consumers.[21] The Institute of Electrical and Electronics Engineers, chaired by Victor Hayes, releases the first wireless local area network (WLAN) standard, the IEEE 802.11, only supporting a maximum network bandwidth of 2 Mbps – too slow for most applications.[22][23]
1997 June 26 Wi-Fi security The Wired Equivalent Privacy (WEP) is introduced as a security algorithm for IEEE 802.11 wireless networks.[16]
1998 Organization Wireless Internet Service Provider MobileStar is founded by Mark Goode and Greg Jackson. MobileStar becomes the first company to provide Wi­Fi hotspots (Mark Goode coined the term “hotspot”) in airports, hotels, or coffee shops, signing contracts with American Airlines, Hilton Hotels, and Starbucks.[14][24]
1999 July Service Apple Corporation introduces Wi-Fi as an option on its new iBook computers, under the brand name AirPort.[15]
