IEEE 802 (1997)
Teknụzụ mgbanwe mgbanwe: nnyefe infrared nke FHSS na DSSS
Arụ ọrụ ugboro band: arụ ọrụ na 2.4GHz ugboro band (2.42.4835GHz, 83.5MHZ na ngụkọta, kewara 13 ọwa (5MHZ n'etiti n'akụkụ ọwa), onye ọ bụla ọwa aza ajụjụ maka 22MHz. Mgbe a na-eji ọwa n'out oge, e nwere atọ ndị na-abụghị. ọwa na-ejikọta ọnụ [1 6 11 ma ọ bụ 2 7 12 ma ọ bụ 3 8 13])
Ọnụọgụ nnyefe: N'oge a, ọnụego nnyefe na-adị nwayọọ na data dị ntakịrị.Enwere ike iji ya naanị maka ọrụ ịnweta data, yana ọnụego nnyefe kacha bụ 2 Mbps.
Ndakọrịta: adịghị dakọtara.
IEEE 802.11a (1999)
Teknụzụ mgbanwe mgbanwe: teknụzụ ewebatara (OFDM), ya bụ nkewa ugboro ugboro ugboro ugboro (OFDM).
Ugboro ugboro na-arụ ọrụ: n'oge a, ọ na-arụ ọrụ na 5.8GHz band band (5.725G5.85GHz, 125MHz na mkpokọta, kewara n'ime ise ọwa, onye ọ bụla ọwa akaụntụ maka 20MHz, na n'akụkụ ọwa adịghị overlack ibe ha, ya bụ, mgbe. A na-eji ọwa ndị ahụ eme ihe n'otu oge, ọwa ise ndị a anaghị ekpuchi ibe ha).
Ọnụego nnyefe: mgbe ọnụego nnyefe na-abawanye, ọ bụ 54, 48, 36, 24, 18, 12, 9, na 6. Nkeji dị na nso a bụ Mbps.
Ndakọrịta: adịghị dakọtara.
IEEE 802.11b (1999)
Teknụzụ mgbanwe: gbasaa ọnọdụ IEEE 802.11 DSSS wee nara usoro mgbanwe CCK
Ugboro ugboro na-arụ ọrụ: 2.4GHz
Ọnụego nnyefe: na-akwado ọnụego dị iche iche nke 11 Mbps, 4.5 Mbps, 2 Mbps, na 1 Mbps
ndakọrịta: Malite ndakọrịta ala na IEEE 802.11
IEEE 802.11g (2003)
Teknụzụ mgbanwe mgbanwe: na-ewebata teknụzụ ugboro ugboro orthogonal multiplexing (OFDM).
Ugboro ugboro na-arụ ọrụ: 2.4GHz
Ọnụego nnyefe: ghọta oke nnyefe data nke 54 Mbps
Ndakọrịta: dakọtara na IEEE 802.11/IEEE 802.11b
IEEE 802.11n (2009)
Teknụzụ mgbanwe mgbanwe: na-ewebata teknụzụ orthogonal nkewa multiplexing (OFDM) teknụzụ + ọtụtụ ntinye / ọtụtụ mmepụta (MIMO) teknụzụ.
Ugboro ugboro na-arụ ọrụ: 2.4G ma ọ bụ 5.8GHz
Nzipu ọnụego: data nnyefe ọsọ nwere ike ruo 300 ~ 600Mbps
Ndakọrịta: dakọtara na IEEE 802.11/IEEE 802.11b/IEEE 802.11a
Ihe dị n'elu bụ usoro akụkọ ihe mere eme nke IEEE802 protocol, nke na-esighị ike ịchọta.Usoro a gụnyere ma 2.4G na 5G band band.Ọzọkwa, site na mmepe nke akụkọ ihe mere eme na nhazigharị nke usoro ahụ mgbe nile, ọnụ ọgụgụ ahụ na-etolite elu.Ugbu a, usoro kachasị ọsọ nke band 2.4G nwere ike iru 300Mbps, na ndekọ ọsọ ọsọ nke band 5G nwere ike iru 866Mbps.
Nchịkọta: Usoro ndị 2.4GWiFi kwadoro bụ: 11, 11b, 11g, na 11n.
Usoro 5GWiFi kwadoro bụ 11a, 11n na 11ac.
