In the 1970s ALOHA random access was employed in the nascent [[Ethernet]] cable based network<ref>{{Cite journal |last1=Metcalfe |first1=Robert M. |author-link=Robert M.

In the early 1980s frequencies for mobile networks became available, and in 1985 frequencies suitable for what became known as [[Wi-Fi]] were allocated in the US.<ref>{{Cite web |date=June 18, 1985 |title=Authorization of Spread Spectrum Systems Under Parts 15 and 90 of the FCC Rules and Regulations |url=http://www.marcus-spectrum.com/documents/81413RO.txt |url-status=dead |archive-url=https://web.archive.org/web/20070928054826/http://www.marcus-spectrum.com/documents/81413RO.txt |archive-date=2007-09-28 |access-date=2007-08-31 |publisher=Federal Communications Commission |format=TXT}}</ref>  These regulatory developments made it possible to use the ALOHA random-access techniques in both Wi-Fi and in mobile telephone networks.

ALOHA channels were used in a limited way in the 1980s in [[1G]] mobile phones for [[signaling protocol|signaling]] and control purposes.<ref>{{Cite conference |last=Stavenow |first=B. |year=1984 |title=Throughput-Delay Characteristics and Stability Considerations of the Access Channel in a Mobile Telephone System |conference=Proceedings of the 1984 ACM SIGMETRICS Conference on Measurement and Modeling of Computer Systems |pages=105–112}}</ref>  In the late 1980s, the European standardization group [[GSM]] who worked on the Pan-European Digital mobile communication system GSM greatly expanded the use of ALOHA channels for access to radio channels in mobile telephony. In addition, [[SMS]] message texting was implemented in 2G mobile phones.  In the early 2000s additional ALOHA channels were added to 2.5G and 3G mobile phones with the widespread introduction of [[General Packet Radio Service]] (GPRS), using a slotted-ALOHA random-access channel combined with a version of the Reservation ALOHA scheme first analyzed by a group at [[BBN Technologies]].<ref>{{Cite conference |last=Crowther |first=Will |author-link=Will Crowther |date=January 1973 |title=A System for Broadcast Communication: Reservation-ALOHA |conference=Proceedings of the 6th Hawaii International Conference on Systems Sciences |pages=371–374 |place=Honolulu}}</ref>
