PHY, gawo lakuthupi la IEEE 802.11, lili ndi mbiri yotsatira ya chitukuko chaukadaulo ndi miyezo yaukadaulo:
IEEE 802 (1997)
Tekinoloje yosinthira: kutumiza kwa infrared kwa FHSS ndi DSSS
Gulu la ma frequency ogwiritsira ntchito: likugwira ntchito mu 2.4GHz frequency band (2.42.4835GHz, 83.5MHZ yonse, yogawidwa m'makanema 13 (5MHZ pakati pa mayendedwe oyandikana), njira iliyonse imawerengera 22MHz. mayendedwe odutsana [1 6 11 kapena 2 7 12 kapena 3 8 13])
Mlingo wotumizira: Pakalipano, kuchuluka kwa kutumizira kumakhala pang'onopang'ono ndipo deta ndi yochepa.Itha kugwiritsidwa ntchito pazithandizo zopezera deta, ndipo kuchuluka kwapanthawi yotumizira ndi 2 Mbps.
Kugwirizana: sikugwirizana.
IEEE 802.11a (1999)
Tekinoloje yosinthira: ukadaulo wodziwika bwino (OFDM), womwe ndi orthogonal frequency division multiplexing (OFDM).
Gulu la ma frequency ogwiritsira ntchito: pakadali pano, limagwira ntchito mu band ya 5.8GHz (5.725G5.85GHz, 125MHz yonse, yogawidwa m'njira zisanu, njira iliyonse imakhala ndi 20MHz, ndipo mayendedwe oyandikana samalumikizana, ndiye kuti, pamene njirazi zimagwiritsidwa ntchito nthawi imodzi, njira zisanuzi sizimayenderana).
Mlingo wotumizira: pamene kuchuluka kwapatsirana kumawonjezeka, ndi 54, 48, 36, 24, 18, 12, 9, ndi 6. Magawo omwe ali mumtundu uwu ndi Mbps.
Kugwirizana: sikugwirizana.
IEEE 802.11b (1999)
Tekinoloje yosinthira: kulitsa mawonekedwe a IEEE 802.11 DSSS ndikutengera njira yosinthira ya CCK
Ma frequency band: 2.4GHz
Mlingo wotumizira: thandizirani mitengo yosiyanasiyana ya 11 Mbps, 4.5 Mbps, 2 Mbps, ndi 1 Mbps
Kugwirizana: Yambitsani kutsika pansi ndi IEEE 802.11
IEEE 802.11g (2003)
Tekinoloje yosinthira: kuyambitsa ukadaulo wa orthogonal frequency division multiplexing (OFDM).
Ma frequency band: 2.4GHz
Mlingo wotumizira: zindikirani kuchuluka kwa kutumizira kwa data kwa 54 Mbps
Kugwirizana: Yogwirizana ndi IEEE 802.11/IEEE 802.11b
IEEE 802.11n (2009)
Tekinoloje yosinthira: kuyambitsa ukadaulo wa orthogonal frequency division multiplexing (OFDM) + matekinoloje angapo / zotulutsa zingapo (MIMO)
Ma frequency band: 2.4G kapena 5.8GHz
Kufala mlingo: liwiro kufala deta akhoza kufika 300 ~ 600Mbps
Kugwirizana: Yogwirizana ndi IEEE 802.11/IEEE 802.11b/IEEE 802.11a
Zomwe zili pamwambazi ndi mbiri yakale ya protocol ya IEEE802, yomwe sizovuta kupeza.Protocol iyi imaphatikizapo magulu onse a 2.4G ndi 5G.Komanso, ndi chitukuko cha mbiriyakale ndi kusinthidwa kosalekeza kwa protocol, mlingo ukukwera mmwamba.Pakalipano, kuthamanga kwapamwamba kwa gulu la 2.4G kumatha kufika 300Mbps, ndipo kujambula kwapamwamba kwa gulu la 5G kumatha kufika 866Mbps.
Mwachidule: Njira zothandizidwa ndi 2.4GWiFi ndi: 11, 11b, 11g, ndi 11n.
Ma protocol omwe amathandizidwa ndi 5GWiFi ndi 11a, 11n, ndi 11ac.
Zomwe zili pamwambazi ndizofotokozera za WLAN Physical Layer PHY zomwe zabweretsedwa kwa inu ndi Shenzhen Haidwiwei Optoelectronics Technology Co., Ltd. Shenzhen Haidiwei Optoelectronics Technology Co., Ltd.mankhwala
