Ibyiza bya WIFI 6 ONT

Ugereranije n'ibisekuru byabanjirije ikoranabuhanga rya WiFi, ibintu by'ingenzi biranga igisekuru gishya cya WiFi 6 ni:
Ugereranije n'ibisekuru byabanjirije 802.11ac WiFi 5, umuvuduko ntarengwa wa WiFi 6 wongerewe kuva kuri 3.5Gbps ya mbere ugera kuri 9.6Gbps, kandi umuvuduko w'amahame wiyongereyeho hafi inshuro 3.
Kubijyanye na bande ya frequency, WiFi 5 irimo 5GHz gusa, mugihe WiFi 6 ikubiyemo 2.4 / 5GHz, ikubiyemo ibikoresho byihuta kandi byihuta.
Kubijyanye nuburyo bwo guhindura, WiFi 6 ishyigikira 1024-QAM, irenga 256-QAM ya WiFi 5, kandi ifite ubushobozi bwamakuru menshi, bivuze ko amakuru yihuta yo kohereza amakuru.

Ubukererwe buke
WiFi 6 ntabwo yiyongera gusa kubiciro byo gukuramo no gukuramo gusa, ahubwo ni iterambere ryinshi mubibazo byurusobe, bituma ibikoresho byinshi bihuza numuyoboro utagira umurongo kandi bifite uburambe buhoraho bwihuse, biterwa ahanini na MU- MIMO na OFDMA ikoranabuhanga rishya.
Igipimo cya WiFi 5 gishyigikira tekinoroji ya MU-MIMO (abakoresha benshi-binjiza byinshi-binjiza byinshi-bisohoka), ifasha gusa kumanura, kandi irashobora kubona ubwo buhanga gusa mugihe cyo gukuramo ibirimo.WiFi 6 ishyigikira kuzamura no kumanura MU-MIMO, bivuze ko MU-MIMO ishobora kuba inararibonye mugihe cyo kohereza no gukuramo amakuru hagati yibikoresho bigendanwa na router idafite umugozi, bikarushaho kunoza imikoreshereze yumurongo wa interineti idafite insinga.
Umubare ntarengwa wimibare yimibare ishyigikiwe na WiFi 6 wongerewe kuva kuri 4 muri WiFi 5 kugeza 8, ni ukuvuga ko ishobora gushyigikira ntarengwa 8 × 8 MU-MIMO, nimwe mumpamvu zingenzi zitera kwiyongera gukomeye muri igipimo cya WiFi 6.
WiFi 6 ikoresha tekinoroji ya OFDMA (Orthogonal Frequency Division Multiple Access), ikaba ari verisiyo ihindagurika ya tekinoroji ya OFDM ikoreshwa muri WiFi 5. Ihuza ikoranabuhanga rya OFDM na FDMA.Nyuma yo gukoresha OFDM kugirango uhindure umuyoboro mubitwara byababyeyi, subcarrier zimwe Ikoranabuhanga ryo kohereza no kohereza amakuru ryemerera abakoresha batandukanye gusangira umuyoboro umwe, bigatuma ibikoresho byinshi bigerwaho, hamwe nigihe gito cyo gusubiza no gutinda kugabanuka.

Byongeye kandi, WiFi 6 ikoresha uburyo bwo kohereza ibimenyetso birebire bya DFDM kugirango yongere igihe cyo kohereza kuri buri cyuma gitwara ibimenyetso kiva kuri 3.2 μs muri WiFi 5 kugeza kuri 12.8 μs, kugabanya igipimo cyo gutakaza paki nigipimo cyo kohereza, kandi bigatuma itumanaho rihagarara neza.

Ubushobozi bunini
WiFi 6 itangiza uburyo bwo gusiga amabara ya BSS, kuranga buri gikoresho gihujwe numuyoboro, no kongeramo ibirango bijyanye namakuru yacyo icyarimwe.Iyo wohereza amakuru, hari adresse ihuye, kandi irashobora koherezwa muburyo butaziguye.

Abakoresha benshi MU-MIMO tekinoroji yemerera ama terefone menshi gusangira umuyoboro wigihe cya mudasobwa, kugirango terefone / mudasobwa nyinshi zigendanwa kuri interineti icyarimwe.Hamwe na tekinoroji ya OFDMA, buri muyoboro uri munsi yumuyoboro wa WiFi 6 urashobora gukora amakuru yihuse yohereza amakuru, guteza imbere abakoresha benshi Ubunararibonye bwurusobekerane muribwo bushobora guhuza neza ibisabwa n’ahantu hotspot ya WiFi, gukoresha abakoresha benshi, kandi ntibyoroshye. gukonjesha, kandi ubushobozi ni bunini.

Umutekano
Niba igikoresho cya WiFi 6 (router idafite umugozi) gikeneye kwemezwa na WiFi Alliance, kigomba kwemeza protocole yumutekano WPA 3, ifite umutekano kurushaho.
Mu ntangiriro za 2018, WiFi Alliance yasohoye igisekuru gishya cya enterineti ya enterineti ya enterineti WPA 3, ikaba ari verisiyo yazamuye porotokole ya WPA 2 ikoreshwa cyane.Umutekano urarushijeho kunozwa, kandi birashobora kurushaho gukumira ibitero byingufu zikaze no gukomera kwingufu.
kuzigama imbaraga nyinshi
WiFi 6 itangiza tekinoroji ya TARget Wake Time (TWT), itanga igenamigambi ryigihe cyitumanaho hagati yibikoresho na router zitagikoreshwa, kugabanya ikoreshwa rya antenne y'urusobemiyoboro hamwe nigihe cyo gushakisha ibimenyetso, bishobora kugabanya gukoresha amashanyarazi kurwego runaka no kuzamura bateri yibikoresho ubuzima.

HUANET itanga WIFI 6 ONT, niba ubishaka, tubwire.
