PHY, urwego rwumubiri rwa IEEE 802.11, rufite amateka akurikira yiterambere ryikoranabuhanga hamwe nubuziranenge bwa tekiniki:
IEEE 802 (1997)
Ikoreshwa rya modulasi: kwanduza infragre ya FHSS na DSSS
Gukoresha imirongo yumurongo: ikorera mumurongo wa 2.4GHz (2.42.4835GHz, 83.5MHZ yose hamwe, igabanijwemo imiyoboro 13 (5MHZ hagati yimiyoboro yegeranye), buri muyoboro uhwanye na 22MHz. Iyo imiyoboro ikoreshwa icyarimwe, hariho eshatu zitari- imiyoboro irenga [1 6 11 cyangwa 2 7 12 cyangwa 3 8 13])
Igipimo cyo kohereza: Muri iki gihe, igipimo cyo kohereza kiratinda kandi amakuru ni make. Irashobora gukoreshwa gusa muri serivisi zo kubona amakuru, kandi igipimo ntarengwa cyo kohereza ni 2 Mbps.
Guhuza: ntabwo bihuye.
IEEE 802.11a (1999)
Tekinoroji yo guhinduranya: tekinoroji yatangijwe kumugaragaro (OFDM), aribyo orthogonal frequency division multiplexing (OFDM).
Gukoresha imirongo yumurongo: muriki gihe, ikorera mumurongo wa 5.8GHz (5.725G5.85GHz, 125MHz yose hamwe, igabanijwemo imiyoboro itanu, buri muyoboro ubarirwa kuri 20MHz, kandi imiyoboro yegeranye ntabwo ihuzagurika, ni ukuvuga, iyo imiyoboro ikoreshwa icyarimwe, iyi miyoboro itanu ntabwo ihuzagurika).
Igipimo cyo kohereza: iyo igipimo cyo kohereza cyiyongereye, ni 54, 48, 36, 24, 18, 12, 9, na 6. Ibice biri muriki cyiciro ni Mbps.
Guhuza: ntabwo bihuye.
IEEE 802.11b (1999)
Tekinoroji yo guhindura: kwagura uburyo bwa IEEE 802.11 DSSS hanyuma ukoreshe uburyo bwo guhindura CCK
Gukoresha imirongo yumurongo: 2.4GHz
Igipimo cyo kohereza: shyigikira ibiciro bitandukanye bya 11 Mbps, 4.5 Mbps, 2 Mbps, na 1 Mbps
Guhuza: Tangira guhuza hasi na IEEE 802.11
IEEE 802.11g (2003)
Ikoreshwa rya modulasiyo: gutangiza orthogonal frequency frequency kugabana Multlexing (OFDM) tekinoroji
Gukoresha imirongo yumurongo: 2.4GHz
Igipimo cyo kohereza: menya igipimo ntarengwa cyo kohereza amakuru ya 54 Mbps
Guhuza: Bihujwe na IEEE 802.11 / IEEE 802.11b
IEEE 802.11n (2009)
Tekinoroji yo guhinduranya: kumenyekanisha uburyo bwa orthogonal frequency kugabana Multlexing (OFDM) tekinoroji + ibyinjijwe byinshi / ibisubizo byinshi (MIMO)
Gukoresha imirongo yumurongo: 2.4G cyangwa 5.8GHz
Igipimo cyo kohereza: umuvuduko wo kohereza amakuru urashobora kugera kuri 300 ~ 600Mbps
Guhuza: Bihujwe na IEEE 802.11 / IEEE 802.11b / IEEE 802.11a
Ibyavuzwe haruguru ninzira yamateka ya protocole ya IEEE802, ntabwo bigoye kuyibona. Iyi protocole ikubiyemo imirongo ya 2.4G na 5G. Byongeye kandi, hamwe niterambere ryamateka no guhora dusubiramo protocole, igipimo kigenda gitera imbere. Kugeza ubu, theoretical maximum umuvuduko wa bande ya 2.4G irashobora kugera kuri 300Mbps, naho umuvuduko mwinshi wo gufata amajwi ya 5G urashobora kugera kuri 866Mbps.
Incamake: Porotokole ishyigikiwe na 2.4GWiFi ni: 11, 11b, 11g, na 11n.
Porotokole ishyigikiwe na 5GWiFi ni 11a, 11n, na 11ac.
