1.Porotokole y'umutekano
Mu miyoboro idafite insinga, akamaro k'umutekano wurusobe ntigashobora gushimangirwa.Wifi numuyoboro udafite umugozi wemerera ibikoresho byinshi nabakoresha guhuza interineti binyuze mumwanya umwe.Wifi nayo ikoreshwa mubisanzwe ahantu hahurira abantu benshi, aho usanga hari kugenzura gake ushobora guhuza umuyoboro.Mu nyubako zamasosiyete, amakuru akenewe agomba kurindwa mugihe hackers mbi zagerageje gusenya cyangwa kwiba amakuru.
Wifi 5 ishyigikira protocole ya WPA na WPA2 kugirango uhuze neza.Izi ningenzi zumutekano wogutezimbere protocole ya WEP itajyanye n'igihe, ariko ubu ifite intege nke nintege nke.Imwe muri izo ntege nke nigitero cyamagambo, aho abanyabyaha ba cyber bashobora guhanura ijambo ryibanga ryibanga hamwe kugerageza hamwe.
Wifi 6 ifite ibikoresho byumutekano bigezweho WPA3.Kubwibyo, ibikoresho bishyigikira Wifi 6 bikoresha protocole ya WPA, WPA2, na WPA3 icyarimwe.Wifi Irinzwe Kwinjira 3 Yateje imbere ibintu byinshi byo kwemeza no kugenzura.Ifite tekinoroji ya OWE ikumira ibanga ryikora, hanyuma, amaherezo, scan ya OR code ihujwe neza nigikoresho.
2.Umuvuduko wo kohereza amakuru
Umuvuduko ni ikintu cyingenzi kandi gishimishije tekinolojiya mishya igomba gukemura mbere yuko isohoka.Umuvuduko ningirakamaro kubintu byose bibaho kuri enterineti nubwoko bwose bwurusobe.Ibiciro byihuse bisobanura igihe gito cyo gukuramo, gutembera neza, kohereza amakuru byihuse, videwo nziza nijwi ryinama, gushakisha byihuse nibindi byinshi.
Wifi 5 ifite theoretic ntarengwa yo kohereza amakuru yihuta ya 6.9 Gbps.Mubuzima busanzwe, impuzandengo yo kohereza amakuru yihuta ya 802.11ac isanzwe ni 200Mbps.Igipimo igipimo cya Wifi gikora giterwa na QAM (quadrature amplitude modulation) numubare wibikoresho bihujwe nokugera cyangwa inzira.Wifi 5 ikoresha modulasi ya 256-QAM, iri munsi cyane ya Wifi 6. Byongeye kandi, tekinoroji ya Wifi 5 MU-MIMO yemerera guhuza icyarimwe ibikoresho bine.Ibikoresho byinshi bisobanura ubwinshi no kugabana umurongo, bigatuma umuvuduko utinda kuri buri gikoresho.
Ibinyuranye, Wifi 6 ni amahitamo meza mubijyanye n'umuvuduko, cyane cyane iyo umuyoboro wuzuye.Ikoresha modulasiyo 1024-QAM kuri theoretique ntarengwa yohereza kugeza kuri 9.6Gbps.wi-fi 5 na wi-fi 6 umuvuduko ntutandukana cyane kubikoresho.Wifi 6 ihora yihuta, ariko inyungu yukuri nyayo nigihe ibikoresho byinshi bihujwe numuyoboro wa Wifi.Umubare nyawo wibikoresho byahujwe bitera kugabanuka cyane mumuvuduko nimbaraga za interineti yibikoresho bya Wifi 5 na router mugihe ukoresheje Wifi 6 ntibizagaragara.
3. Uburyo bwo gushiraho ibiti
Gukora ibiti ni tekinike yo kohereza ibimenyetso biyobora ikimenyetso kitagira umugozi kubakira runaka, aho gukwirakwiza ibimenyetso bivuye mu bundi buryo.Ukoresheje urumuri, aho rugera rushobora kohereza amakuru kubikoresho aho gutangaza ibimenyetso mubyerekezo byose.Gukora ibiti ntabwo ari tekinolojiya mishya kandi ifite porogaramu muri Wifi 4 na Wifi 5. Mubisanzwe bya Wifi 5, hakoreshwa antene enye gusa.Wifi 6, ariko, ikoresha antene umunani.Nibyiza bya Wifi ya router yo gukoresha tekinoroji ikora ibiti, nibyiza igipimo cyamakuru hamwe nurwego rwibimenyetso.
4. Orthogonal Frequency Division Igice Cyinshi (OFDMA)
Wifi 5 ikoresha tekinoroji yitwa orthogonal frequency division multiplexing (OFDM) mugucunga imiyoboro.Nubuhanga bwo kugenzura umubare wabakoresha bagera kuri subcarrier mugihe runaka.Muburyo bwa 802.11ac, 20mhz, 40mhz, 80mhz na 160mhz bande zifite 64 zo munsi, 128 munsi ya 256, 256 subcarrier na 512.Ibi bigabanya cyane umubare wabakoresha bashobora guhuza no gukoresha umuyoboro wa Wifi mugihe runaka.
Wifi 6, kurundi ruhande, ikoresha OFDMA (orthogonal frequency division igabana inshuro nyinshi).Tekinoroji ya OFDMA igwiza umwanya uhari munsi yumurongo umwe.Mugukora ibi, abakoresha ntibagomba gutegereza umurongo kubatwara-kubuntu, ariko barashobora kubona byoroshye.
OFDMA igenera ibikoresho bitandukanye kubakoresha benshi.OFDMA isaba inshuro enye subcarrier kuri buri murongo wa tekinoroji nka tekinoroji yabanjirije.Ibi bivuze ko mumiyoboro ya 20mhz, 40mhz, 80mhz, na 160mhz, 802.11ax isanzwe ifite 256, 512, 1024, na 2048.Ibi bigabanya ubukana nubukererwe, nubwo uhuza ibikoresho byinshi.OFDMA itezimbere imikorere kandi igabanya ubukererwe, bigatuma iba nziza kubikorwa bito.
5. Umukoresha Winshi Yinjiza Byinshi Ibisohoka (MU-MIMO)
MU MIMO bisobanura “umukoresha benshi, ibyinjijwe byinshi, ibisohoka byinshi”.Nikoranabuhanga ridafite umugozi ryemerera abakoresha benshi kuvugana na router icyarimwe.Kuva kuri Wifi 5 kugeza Wifi 6, ubushobozi bwa MU MIMO buratandukanye cyane.
Wifi 5 ikoresha hasi, inzira imwe 4 × 4 MU-MIMO.Ibi bivuze ko abakoresha benshi bafite aho bagarukira barashobora kugera kuri router hamwe na Wifi ihamye.Iyo imipaka ya 4 icyarimwe icyarimwe irenze, Wifi iba yuzuye kandi igatangira kwerekana ibimenyetso byubucucike, nko gutinda kwinshi, gutakaza paki, nibindi.
Wifi 6 ikoresha tekinoroji ya 8 × 8 MU MIMO.Ibi birashobora gukoresha ibikoresho bigera kuri 8 byahujwe no gukoresha cyane LAN idafite umugozi nta nkomyi.Icyiza kurushaho, kuzamura Wifi 6 MU MIMO ni byerekezo byombi, bivuze ko periferique ishobora guhuza na router kumirongo myinshi yumurongo.Ibi bivuze ubushobozi bunoze bwo kohereza amakuru kuri enterineti, mubindi bikoreshwa.
6. Amatsinda yumurongo
Itandukaniro rigaragara hagati ya Wifi 5 na Wifi 6 ni imirongo yumurongo wa tekinoroji ebyiri.Wifi 5 ikoresha gusa 5GHz bande kandi ifite intervention nke.Ikibi ni uko ibimenyetso byerekana ko ari bigufi kandi ubushobozi bwo kwinjira mu rukuta nizindi nzitizi bikagabanuka.
Ku rundi ruhande, Wifi 6, ikoresha imirongo ibiri ya bande, isanzwe 2.4Ghz na 5Ghz.Muri Wifi 6e, abitezimbere bazongera bande 6ghz mumuryango Wifi 6.Wifi 6 ikoresha imirongo ya 2.4Ghz na 5Ghz, bivuze ko ibikoresho bishobora guhita bisikana kandi bigakoresha iyi bande bitavangiye kandi bikoreshwa neza.Ubu buryo, abakoresha babona ibyiza byurusobe rwombi, hamwe n'umuvuduko wihuse kurwego rwegereye kandi mugari mugihe mugihe peripheri itari ahantu hamwe.
7. Kuboneka amabara ya BSS
BSS ibara ni ikindi kintu kiranga Wifi 6 itandukanya ibisekuruza byabanje.Nibintu bishya biranga Wifi 6.BSS, cyangwa serivisi yibanze yashizweho, ubwayo iranga buri rezo ya 802.11.Nyamara, Wifi 6 gusa nibisekuruza bizaza bazashobora gusobanura amabara ya BSS mubindi bikoresho ukoresheje ibara rya BSS.Iyi mikorere ningirakamaro kuko ifasha gukumira ibimenyetso kurenga.
8. Itandukaniro ryigihe cyubushakashatsi
Ubukererwe bivuga gutinda kohereza paki kuva ahantu hamwe bijya ahandi.Umuvuduko muto wo gutinda hafi ya zeru nibyiza, byerekana bike cyangwa nta gutinda.Ugereranije na Wifi 5, Wifi 6 ifite ubukererwe bugufi, bigatuma biba byiza mubucuruzi nubucuruzi bwimishinga.Abakoresha urugo nabo bazakunda iyi mikorere kuri moderi ya Wifi iheruka, kuko bivuze byihuse Muriternet.
