2.4GWiFi wuxuu ku shaqeeyaa xadhkaha soo noqnoqda ee 2.4GHz, oo leh xaddi soo noqnoqda oo ah 2400-2483.5MHz. Halbeegga ugu weyn ee la raacay waa IEEE802.11b/g/n heerka uu soo saaray Machadka Injineerada Korontada iyo Elektarooniga (IEEE). Hoosta, waxaan ku siin doonaa horudhac faahfaahsan heerarkan:
• IEEE802.11 waa halbeeg shabakad degaanka wirelesska ah oo asal ahaan ay samaysay IEEE, inta badan loo isticmaalo in lagu xalliyo marin-u-helka wireless-ka ee isticmaalayaasha iyo marinnada isticmaalaha ee xafiisyada iyo shabakadaha kambaska. Ganacsigu inta badan waxa uu ku xaddidan yahay helitaanka xogta, iyo xawaaraha ugu badan waxa uu gaari karaa oo keliya 2Mb/s. Sababtoo ah awood la'aanta IEEE 802.11 si loo daboolo baahiyaha dadka ee xawaaraha iyo fogaanta gudbinta, tignoolajiyadani waa duugowday.
• Heerka IEEE802.11b, oo sidoo kale loo yaqaano tignoolajiyada daacadnimada wireless, waxay isticmaashaa 2.4GHz band soo noqnoqoshada bilaashka ah ee caalami ahaan la aqoonsan yahay oo loogu talagalay faafinta isku xigxiga tooska ah, oo leh xajmigu yahay 83.5MHz iyo heerka gudbinta xogta ugu badan ee 11Mbps. Baaxadda gudbinta ee aan fidin toosan lahayn ayaa ah ilaa 300 mitir oo bannaanka ah iyo ilaa 100 mitir gudaha gudaha iyada oo aan carqaladayn, taas oo ka dhigaysa borotokoolka gudbinta wireless-ka ee inta badan la isticmaalo maanta.
• IEEE802.11g waa halbeeg isku-dhafan oo la qabsanaya heerka caadiga ah ee 802.11b wuxuuna bixiyaa xawilaadda xogta ee 11Mbps ilbiriqsi kasta 2.4GHz. Waxay qabataa tignoolajiyada la xoojiyey sida xidhitaanka laba kanaal, taas oo kordhisa xawaaraha gudbinta kanaalka wireless ilaa 108Mbps waxayna bixin kartaa wax soo saarka TCP/IP dhabta ah ee 80 ilaa 90Mbps.
• IEEE802.11n waxay qabataa tignoolajiyada MIMO (Multiple In Multiple Out) iyo OFDM (Orthogonal Frequency Division Multiplexing), taas oo kordhin karta heerka gudbinta WLAN 54Mbps ee ay bixiso 802.11a iyo 802.11g ilaa 108Mbps, ama xataa ilaa 600Mbps waxay taageeri kartaa gudbinta codka iyo muuqaalka tayada sare leh.
