PHY, lakabka jireed ee IEEE 802.11, ayaa leh taariikhda soo socota ee horumarinta tignoolajiyada iyo heerarka farsamada:
IEEE 802 (1997)
Farsamada wax-ka-beddelka: gudbinta infrared ee FHSS iyo DSSS
Band soo noqnoqda Operating: ka shaqeeya band soo noqnoqda 2.4GHz (2.42.4835GHz, 83.5MHZ wadar ahaan, qaybsan 13 channels (5MHZ inta u dhaxaysa channels ku xiga), channel kasta xisaabin 22MHz. Marka kanaalada la isticmaalo isku mar, waxaa jira saddex non- kanaalada is-dul-saaran [1 6 11 ama 2 7 12 ama 3 8 13])
Heerka gudbinta: Waqtigan, heerka gudbintu waa yara gaabis ah xogtuna waa xadidan tahay. Waxa kaliya oo loo isticmaali karaa adeegyada helitaanka xogta, iyo heerka gudbinta ugu badan waa 2 Mbps.
Waafaqid: ma socon karto.
IEEE 802.11a (1999)
Farsamada wax-ka-beddelka: tignoolajiyada si rasmi ah loo soo bandhigay (OFDM), kuwaas oo kala qaybinta soo noqnoqda orthogonal multiplexing (OFDM).
Xaddiga soo noqnoqda: wakhtigan, waxa uu ku shaqeeyaa xadiga soo noqnoqda ee 5.8GHz (5.725G5.85GHz, 125Mhz guud ahaan, waxa loo qaybiyaa shan kanaal, kanaalkasta waxa uu xisaabiyaa 20MHz, kanaalka ku xigana isma dulsaaran yihiin, waa marka. Kanaalka ayaa isku mar la wada isticmaalaa, shantan kanaal isma dul saaran yihiin).
Heerka gudbinta: marka heerka gudbintu kordho, waa 54, 48, 36, 24, 18, 12, 9, iyo 6. Halbeegyada kala duwanaanshiyahan waa Mbps.
Waafaqid: ma socon karto.
IEEE 802.11b (1999)
Farsamada wax-ka-beddelka: balaadhi qaabka IEEE 802.11 DSSS oo qaado habka habaynta CCK
band inta jeer ee shaqaynaysa: 2.4GHz
Heerka gudbinta: taageer heerarka kala duwan ee 11 Mbps, 4.5 Mbps, 2 Mbps, iyo 1 Mbps
Waafaqsanaan: Ka biloow hoos u waafaqid IEEE 802.11
IEEE 802.11g (2003)
Farsamada wax-ka-beddelka: soo bandhigida tignoolajiyada kala qaybinta soo noqnoqda orthogonal multiplexing (OFDM).
band inta jeer ee shaqaynaysa: 2.4GHz
Heerka gudbinta: ogow heerka gudbinta xogta ugu badan ee 54 Mbps
Waafaqid: Waafaqsan IEEE 802.11/IEEE 802.11b
IEEE 802.11n (2009)
Farsamada wax-ka-beddelka: soo bandhigida teknoolojiyadda kala qaybinta soo noqnoqoshada orthogonal-ka (OFDM) + tignoolajiyada wax-soo-saarka badan/wax-soo-saarka badan (MIMO)
Xaddidaadda inta jeer ee shaqaynaysa: 2.4G ama 5.8GHz
Heerka gudbinta: Xawaaraha gudbinta xogta wuxuu noqon karaa ilaa 300 ~ 600Mbps
Waafaqid: Waafaqsan IEEE 802.11/IEEE 802.11b/IEEE 802.11a
Kuwa kore waa habka taariikhiga ah ee borotokoolka IEEE802, taas oo aan dhib lahayn in la helo. Hab-maamuuska waxa ku jira labada xabbo ee 2.4G iyo 5G. Waxaa intaa dheer, horumarinta taariikhda iyo dib u eegista joogtada ah ee borotokoolka, heerka ayaa kor u kacaya. Waqtigan xaadirka ah, xawaaraha ugu sarreeya aragtida ee band 2.4G wuxuu gaari karaa 300Mbps, iyo duubista xawaaraha ugu badan ee band 5G wuxuu gaari karaa 866Mbps.
Soo koobid: Xeerarka uu taageeray 2.4GWiFi waa: 11, 11b, 11g, iyo 11n.
Hab-maamuusyada uu taageeray 5GWiFi waa 11a, 11n, iyo 11ac.
