Alohanet, an early wireless data network conceived and birthed in Hawaii, is one such landmark innovation, acting as a precursor to the modern wireless networks .Norm Abramson started ALOHAnet at the University of Hawaii in the early 1970s. The first packet-switched wireless digital network, it inspired Ethernet and is an ancestor of GSM, Wi-Fi, 3G and Bluetooth. While the ALOHAnet on its own was a revolutionary invention, the connection of ALOHAnet to ARPANET via satellite is considered by many to be even more meaningful by signifying the birth .

ALOHAnet entrou em operação em 1971, conectando os computadores das ilhas do Havaí através de rádio. Uma das características revolucionárias da ALOHAnet foi sua capacidade de permitir que vários usuários transmitissem dados simultaneamente, sem a necessidade de um coordenador centralizado. Isso foi possível graças ao protocolo .

ALOHAnet is an important part of telecommunication development because it demonstrated the viability of random access protocols. Unlike existing protocols at the time in which users directly communicated to one another to avoid collisions between user traffics, ALOHAnet proposed the wild idea of letting all the client nodes communicate .
