2.4G WiFi o loʻo galue i le 2.4GHz faʻatasi ma le faʻaogaina o le tele o taimi ole 2400 ~ 2483.5MHz. O le faʻataʻitaʻiga autu e mulimulitaʻia o le IEEE802.11b / g / n tulaga faʻatulagaina e le IEEE (Association of Electrical and Electronics Engineers). auiliili:
- O le IEEE802.11 o se laina fa'asalalau LAN uaealesi na fa'avae muamua e le IEEE.E masani ona faʻaaogaina e foia ai le fesoʻotaʻiga uaealesi i tagata faʻaoga ma faʻaoga faʻaoga i le ofisa LAN ma le lotoa.Au'aunaga e fa'atapula'a lava i le mauaina o fa'amatalaga, ma le maualuga maualuga o le 2Mb / s.O lenei tekonolosi ua tuai ona o le IEEE802.11 e le'o lelei i fua fa'atatau ma felauaiga mamao.
- O le tulaga IEEE802.11b, e lauiloa foi o tekinolosi faʻamaoni uaealesi, faʻaaogaina le faʻasalalauga faʻavaomalo 2.4GHz faʻasalalau faʻasalalau saoloto mo le faʻalauteleina o le faʻasologa tuusaʻo, ma le 83.5MHz lautele ma le maualuga o le faʻasalalauga faʻamatalaga o le 11Mbps. O le maualuga o le faʻasalalauga faʻasalalau e 300 mita i fafo ma 100 mita i totonu e aunoa ma le fa'aogaina i totonu, o le fa'aogaina o feso'ota'iga uaealesi i le taimi nei.
- IEEE802.11g o se faʻataʻitaʻiga tuʻufaʻatasia e fetaui ma le masani masani 802.11b ma tuʻuina atu faʻamatalaga faʻaliliuga fua faatatau o le 11Mbps i le sekone i le 2.4GHz. E faʻaaogaina tekinolosi faʻaleleia e pei o le faʻapipiʻi lua-auala, lea e faʻaleleia ai le bandwidth transmission channel wireless i le 108Mbps ma mafai. tuʻuina atu se TCP / IP moni faʻaogaina i le va o le 80 ma le 90Mbps.
- IEEE802.11n faʻaaogaina le MIMO (tele-in ma multi-out) ma le OFDM (orthogonal frequency division multiplexing) tekinolosi, lea e mafai ona faʻaleleia le saoasaoa o le WLAN mai le 54Mbps o loʻo iai nei e 802.11a ma le 802.11g i le 108Mbps, e oʻo lava ile 600Mbps. , ma e mafai ona lagolagoina leo maualuga ma le fa'asalalauga vitio.
