Akamaro ka WIFI 6 ONT

Ugereranyije n'ikoranabuhanga rya WiFi ryakozwe mu bihe byashize, ibintu by'ingenzi bigize WiFi 6 ni ibi bikurikira:
Ugereranyije n'igihe cyashize cya 802.11ac WiFi 5, igipimo ntarengwa cyo kohereza WiFi 6 cyazamutse kiva kuri 3.5Gbps ugereranyije n'icya mbere kigera kuri 9.6Gbps, kandi umuvuduko w'ibitekerezo wiyongereyeho hafi inshuro 3.
Ku bijyanye n'imirongo y'itumanaho, WiFi 5 ikoresha 5GHz gusa, mu gihe WiFi 6 ikoresha 2.4/5GHz, ikoresha ibikoresho byihuta cyane kandi byihuta cyane.
Ku bijyanye n'uburyo bwo guhindura amakuru, WiFi 6 ishyigikira 1024-QAM, iri hejuru ya 256-QAM ya WiFi 5, kandi ifite ubushobozi bwo gukoresha amakuru menshi, bivuze ko umuvuduko wo kohereza amakuru uri hejuru.

Gutinda guke
WiFi 6 ntabwo ari ukwiyongera kw'ibipimo byo gushyira no gukuramo amakuru gusa, ahubwo ni no kunoza cyane ubucucike bw'imiyoboro ya interineti, bigatuma ibikoresho byinshi bihuzwa n'umuyoboro wa interineti utagira umugozi kandi bikagira uburambe buhoraho bwo guhuza amakuru ku muvuduko mwinshi, ibi ahanini biterwa n'ikoranabuhanga rishya rya MU-MIMO na OFDMA.
Uburyo bwa WiFi 5 bukoreshwa mu ikoranabuhanga rya MU-MIMO (multi-user multi-input multi-output), rikoreshwa gusa mu gushyira amakuru kuri interineti, kandi rishobora gukoresha iri koranabuhanga gusa iyo umuntu akura amakuru kuri interineti. WiFi 6 ikoreshwa mu gushyira amakuru kuri interineti ndetse no kuyashyira kuri interineti kuri interineti, bivuze ko MU-MIMO ishobora gukoreshwa iyo umuntu akura amakuru hagati y’ibikoresho bya telefoni zigendanwa na za router zitagira umugozi, birushaho kunoza imikoreshereze y’umurongo wa interineti w’itumanaho ritagira umugozi.
Umubare ntarengwa w'amakuru akoreshwa na WiFi 6 wongerewe uva kuri 4 muri WiFi 5 ugera kuri 8, ni ukuvuga ko ushobora gushyigikira MU-MIMO ntarengwa ya 8×8, iyi ikaba ari imwe mu mpamvu zikomeye z'izamuka rikomeye ry'umuvuduko wa WiFi 6.
WiFi 6 ikoresha ikoranabuhanga rya OFDMA (Orthogonal Frequency Division Multiple Access), rikaba ari verisiyo yavuguruye y’ikoranabuhanga rya OFDM rikoreshwa muri WiFi 5. Ihuza ikoranabuhanga rya OFDM na FDMA. Nyuma yo gukoresha OFDM guhindura umuyoboro ukaba umuyoboro mukuru, zimwe mu modoka ntoya Ikoranabuhanga ryo kohereza no kohereza amakuru ryemerera abakoresha batandukanye gusangira umuyoboro umwe, bigatuma ibikoresho byinshi bigerwaho, hamwe n’igihe gito cyo gusubiza no gutinda kugabanuka.

Byongeye kandi, WiFi 6 ikoresha uburyo bwo kohereza ikimenyetso cya Long DFDM kugira ngo yongere igihe cyo kohereza cya buri mashini itwara ibimenyetso kuva kuri 3.2 μs muri WiFi 5 kugera kuri 12.8 μs, bigabanya igipimo cyo gutakaza paki n'igipimo cyo kongera kohereza, kandi bigatuma kohereza birushaho kuba bihamye.

Ubushobozi bunini
WiFi 6 ishyiramo uburyo bwa BSS Coloring, ikaranga buri gikoresho gihujwe n'umuyoboro w'itumanaho, kandi ikongeraho ibirango bihuye nacyo icyarimwe. Mu kohereza amakuru, hari aderesi ijyanye nayo, kandi ishobora koherezwa mu buryo butaziguye nta rujijo.

Ikoranabuhanga rya MU-MIMO rikoresha abantu benshi ryemerera terminals nyinshi gusangira umuyoboro w'igihe cy'umuyoboro wa mudasobwa, kugira ngo telefoni zigendanwa/mudasobwa nyinshi zishobore gukoresha interineti icyarimwe. Hamwe n'ikoranabuhanga rya OFDMA, buri muyoboro uri munsi ya WiFi 6 ushobora kohereza amakuru neza, bikanoza abakoresha benshi. Ubunararibonye bwa network muri ako gace bushobora kuzuza neza ibisabwa n'ahantu hazwi cyane ho WiFi, ikoreshwa ry'abakoresha benshi, kandi ntabwo byoroshye kuyihagarika, kandi ubushobozi bwayo ni bwinshi.

Umutekano
Niba igikoresho cya WiFi 6 (router idafite umugozi) gikeneye kwemezwa na WiFi Alliance, kigomba gukoresha protocole y'umutekano ya WPA 3, ikaba ifite umutekano mwinshi.
Mu ntangiriro za 2018, WiFi Alliance yasohoye protocole nshya ya WiFi encryption WPA 3, ikaba ari verisiyo ivuguruye ya protocole ya WPA 2 ikoreshwa cyane. Umutekano urushaho kunozwa, kandi ushobora gukumira neza ibitero by’ingabo z’abagizi ba nabi n’ingufu z’abagizi ba nabi.
kuzigama ingufu nyinshi
WiFi 6 ishyira ahagaragara ikoranabuhanga rya TARget Wake Time (TWT), rituma habaho igenamigambi ry’igihe cy’itumanaho hagati y’ibikoresho na router zidafite insinga, rigabanya ikoreshwa rya antene z’umuyoboro udafite insinga n’igihe cyo gushakisha ibimenyetso, ibi bikaba bishobora kugabanya ikoreshwa ry’amashanyarazi ku rugero runaka no kunoza ubuzima bwa bateri y’ibikoresho.

HUANET itanga WIFI 6 ONT, niba ubyifuza, turagusaba kutwandikira.
