Nhoroondo neMhando dze Wi-Fi
Muma1980, teknolojia yakagadzirirwa mabhadhari emari asingasviki ainzi WaveLAN yakagadzirwa uye yakagoverwa neIsimba reMagetsi neElectronic Engineers (IEEE) boka rinotarisirwa kuita mitemo, inozivikanwa sekomiti 802. Iyi teknolojia yakawedzerwa mberi muma 1990 kusvika komiti yakabudiswa muzinga 802.11 muna 1997.
Fomu yekutanga ye Wi-Fi kubva munharaunda iyoyo ya 1997 yakatsigirwa 2 Mbps chete . Iyi teknolojia yakange isina kuzivikanwa se "Wi-Fi" kubvira pakutanga; iyo izwi rakagadzirwa makore mashomanana chete sezvo kupararira kwaro kuwedzera. Imwe maitiro emabhizimisi eboka akaramba achichinja mhando kubva ipapo, zvichiita mhuri yezvitsva zveWi-Fi zvinonzi dzinotevera 802.11b, 802.11g, 802.11n, 802.11ac, nezvimwe zvakadaro. Chimwe nechimwe chezvinhu izvi zvakabatana zvinogona kutaurirana, kunyange zvazvo shanduro itsva dzichipa hutano hwakanaka uye nezvimwe zvinhu.
