2.4G WiFi waxa uu ku shaqeeyaa xawaaladaha 2.4GHz oo leh kala duwanaansho shaqo oo kala duwan oo ah 2400~2483.5Mhz.Heerka ugu wayn ee raacaya waa heerka IEEE802.11b/g/n oo ay dejisay IEEE (Ururka Injineerada Korontada iyo Elektarooniga) si faahfaahsan:
- IEEE802.11 waa halbeega LAN-ka bilaa-waayirka ah oo asal ahaan ay samaysay IEEE.Inta badan waxaa loo isticmaalaa in lagu xalliyo marin-u-helka bilaa-waayirka ee isticmaalayaasha iyo marinnada isticmaalaha ee xafiiska LAN iyo shabakadaha kambaska.Adeeggu inta badan waxa uu ku kooban yahay helitaanka xogta, oo leh ugu badnaan 2Mb / s. Farsamadani waa duugowday sababtoo ah IEEE802.11 kuma filna heerka iyo fogaanta gudbinta labadaba.
- Heerka IEEE802.11b, oo sidoo kale loo yaqaano tikniyoolajiyadda daacadnimada wireless, waxay isticmaashaa 2.4GHz band caalami ah oo lacag la'aan ah oo loogu talagalay ballaarinta isku xigxiga tooska ah, oo leh ballac 83.5MHz iyo heerka ugu sarreeya ee gudbinta xogta ee 11Mbps. Xadka gudbinta ugu badan waa 300 mitir dibadda iyo 100 mitir gudaha gudaha iyada oo aan la geli karin gudaha gudaha, taas oo ah borotokoolka gudbinta wireless-ka ugu isticmaalka badan hadda.
- IEEE802.11g waa halbeeg isku-dhafan oo la qabsanaya heerka caadiga ah ee 802.11b wuxuuna bixiyaa xogta xawilaadda xogta ee 11Mbps ilbiriqsi kasta 2.4GHz.Waxay adeegsataa tignoolajiyada kor u qaadida sida xidhmooyinka dual-channel, taas oo wanaajisa xawaaraha gudbinta kanaalka wireless ilaa 108Mbps oo awood u leh Bixi wax soo saarka TCP / IP dhabta ah oo u dhexeeya 80 iyo 90Mbps.
- IEEE802.11n waxa ay isticmaashaa MIMO (multi-in and multi-out) iyo OFDM (orthogonal frequency division multiplexing) tignoolajiyada, taas oo wanaajin karta heerka gudbinta WLAN ee hadda 54Mbps ee ay bixiso 802.11a iyo 802.11g ilaa 108Mbps, xataa ilaa 600Mbps , oo taageeri kara gudbinta codka iyo muuqaalka tayada sare leh.
