2.4GWiFi o lo'o fa'agaoioia i le 2.4GHz frequency band, fa'atasi ai ma le fa'asologa ole 2400-2483.5MHz. O le tulaga autu o loʻo mulimulitaʻia o le IEEE802.11b/g/n faʻataʻatiaina e le Inisetiute o Eletise ma Eletise Inisinia (IEEE). Lalo, o le a matou tuʻuina atu se faʻamatalaga auiliili i nei tulaga:
• O le IEEE802.11 ose tulaga fa'apitonu'u fa'apitonu'u uaealesi na fa'avaeina e le IEEE, e masani ona fa'aoga e foia ai le fa'aogaina o feso'ota'iga uaealesi mo tagata fa'aoga ma fa'aoga fa'aoga ile ofisa ma le lotoa. Ole pisinisi e fa'atapula'a ile mauaina o fa'amatalaga, ma ole saoasaoa maualuga e mafai ona o'o ile 2Mb/s. Ona o le le mafai e le IEEE 802.11 ona faʻafetaui manaʻoga o tagata i tulaga o le saoasaoa ma le mamao o le felauaiga, o lenei tekinolosi ua tuai.
• O le tulaga IEEE802.11b, e taʻua foi o tekinolosi faʻamaoni uaealesi, faʻaaogaina le faʻasalalauga faʻasalalau faʻavaomalo 2.4GHz mo le faʻasologa saʻo o alaleo faʻasalalau, faʻatasi ai ma le bandwidth o le 83.5MHz ma le maualuga o faʻasalalauga faʻamatalaga o le 11Mbps. O le laina fa'asalalau e aunoa ma le fa'asalalauina laina e o'o atu i le 300 mita i fafo ma e o'o atu i le 100 mita i totonu e aunoa ma ni fa'alavelave, ma avea ai ma fa'aoga fa'aoga uaealesi i aso nei.
• IEEE802.11g o se fa'asologa tu'ufa'atasi e fa'afetaui i le fa'aleaganu'u masani 802.11b ma tu'uina atu le fa'aliliuga o fa'amatalaga o le 11Mbps i le sekone i le 2.4GHz taimi. Na te faʻaaogaina tekinolosi faʻaleleia e pei o le faʻapipiʻiina o alalaupapa lua, lea e faʻateleina ai le bandwidth faʻasalalau alalaupapa i le 108Mbps ma e mafai ona maua ai le TCP/IP moni ole 80 i le 90Mbps.
• IEEE802.11n faʻaaogaina MIMO (Multiple In Multiple Out) ma OFDM (Orthogonal Frequency Division Multiplexing) tekinolosi, lea e mafai ona faʻateleina le saoasaoa o le WLAN mai le 54Mbps e tuʻuina atu e le 802.11a ma le 802.11g i le taimi nei i le 108Mbps, pe oʻo lava i le 600Mbps, ma e mafai ona lagolagoina leo maualuga ma felauaiga vitio.

Shenzhen Haidiwei Optoelectronics o se gaosiga faʻapolofesa oONUmasini pusi opitika ma fesootaiga atamaiONUpusi opitika module. O la matou kamupani o loʻo faʻatau atu nei masini fesoʻotaʻiga eseese ma luga ma lalo fesoʻotaʻiga, e pei o fiber optic transceivers, Ethernet switch,OLTmeafaigaluega pusi mata,ONUmeafaigaluega pusi mata, ma isi. Afai e te manaʻo e aʻoaʻo atili e uiga i fesoʻotaʻiga tekonolosi malamalama, faʻamolemole lagona le saoloto e faʻafesoʻotaʻi la matou kamupani.
