Alangizidwa: Kodi Router ndi chiyani ndipo imagwira ntchito bwanji?
Komabe, chinthu chimodzi chomwe mungagule pakali pano ndi rauta ya Wi-Fi 6. Phindu limodzi lomwe mukuliwona pano ndikuti ngati mutha kulumikiza zida zambiri (Wi-Fi 5) ku rauta yanu yatsopano. Kuti mupeze zabwino zonse, dikirani zida zofananira za Wi-Fi 6 kuti zilowe pamsika.
Zowoneka bwino za Wi-Fi 6
Ngati makampani apamwamba atulutsa kale mafoni a Wi-Fi 6 ndipo akuti makampani ena atsatira, payenera kukhala phindu lalikulu. Apa, tiwona zomwe zatsopano za mtundu waposachedwa ndi.
1. Zowonjezera zambiri
Wi-Fi 6 ili ndi njira yotakata. Gulu la Wi-Fi lomwe linali 80 MHz limawirikiza kawiri mpaka 160 MHz. Izi zimathandiza kugwirizana mofulumira pakati pa rauta ndi chipangizo chanu. Ndi Wi-Fi 6, wosuta amatha kutsitsa/kukweza mafayilo akulu mosavuta, kuwonera makanema a 8k. Zida zonse zanzeru m'nyumba zimayenda bwino popanda kusungidwa.
2. Kugwiritsa ntchito mphamvu zamagetsi
Ntchito ya Target Wake Time imapangitsa kuti dongosolo likhale logwira ntchito bwino. Zipangizo zimatha kukambirana nthawi yomwe zimakhala maso komanso nthawi yotumiza/kulandira deta. Moyo wa batri wa Zida za IoT ndi zida zina zotsika mphamvu zimasinthidwa kwambiri mukawonjezera nthawi yogona ya chipangizocho.
3. Palibenso mikangano ndi ma routers ena pafupi
Chizindikiro chanu chopanda zingwe chimakhala ndi vuto chifukwa chakusokonezedwa ndi maukonde ena omwe ali pafupi. Wi-Fi 6's Base Service Station (BSS) ndi yamitundu. Mafelemu amalembedwa kuti rauta isanyalanyaze maukonde oyandikana nawo. Ndi mtundu, tikunena za mtengo pakati pa 0 mpaka 7 womwe umaperekedwa kumalo ofikira.
4. Kukhazikika kokhazikika m'malo odzaza anthu
Tonse tawona kuchepa kwa liwiro tikamayesa kupeza Wi-Fi m'malo odzaza anthu. Yakwana nthawi yoti tisiyane ndi nkhaniyi! The 8X8 MU-MIMO mu Wi-Fi 6 imagwira ntchito ndikutsitsa ndikutsitsa. Mpaka mtundu wam'mbuyomu, MU-MIMO idagwira ntchito ndikutsitsa kokha. Tsopano, ogwiritsa ntchito amatha kusankha kuchokera pamitsinje yopitilira 8. Chifukwa chake, ngakhale ogwiritsa ntchito angapo atapeza rauta nthawi imodzi, palibe kutsika kwakukulu kwamtundu wa bandwidth. Mutha kutsitsa, kutsitsa, komanso kusewera masewera a pa intaneti ambiri osakumana ndi zovuta.
Kodi dongosololi limatha bwanji kusokonekera?
Apa tiyenera kudziwa zaukadaulo wotchedwa OFDMA - Orthogonal Frequency Division Multiple Access . Mwa izi, malo ofikira a Wi-Fi amatha kuyankhula ndi zida zingapo nthawi imodzi. Njira ya Wi-Fi imagawidwa m'magulu angapo. Ndiko kuti, njirayo imagawidwa m'malo ang'onoang'ono. Iliyonse mwa njira yaying'onoyi imatchedwa a gawo lothandizira (RU) . Zomwe zimapangidwira zida zosiyanasiyana zimanyamulidwa ndi ma subchannel. OFDMA ikuyesera kuthetsa vuto la latency, lomwe liri lofala masiku ano pa Wi-Fi.
OFDMA imagwira ntchito mosinthika. Tinene kuti pali zida ziwiri - PC ndi foni yolumikizana ndi tchanelo. Router imatha kugawa magawo awiri azinthu zothandizira pazida izi kapena kugawa zomwe zimafunikira pa chipangizo chilichonse pakati pa zida zingapo.
Makina omwe utoto wa BSS umagwirira ntchito amatchedwa spatial frequency reuse. Izi zimathandizanso kuthetsa kusokonekera chifukwa cha zida zingapo zolumikizira nthawi imodzi.
Chifukwa chiyani izi?
Wi-Fi 5 itatulutsidwa, anthu ambiri aku US anali ndi zida za Wi-Fi pafupifupi 5. Masiku ano, chawonjezeka pafupifupi 9 zipangizo. Akuti chiŵerengerochi chikungowonjezereka. Chifukwa chake, zikuwonekeratu kuti pakufunika kufunikira kokhala ndi zida zambiri za Wi-Fi. Apo ayi, rauta sangathe kutenga katunduyo. Idzachepetsa mofulumira.
Kumbukirani kuti, ngati mulumikiza chipangizo chimodzi cha Wi-Fi 6 ku rauta ya Wi-Fi 6, simungazindikire kusintha kulikonse kwa liwiro. Cholinga chachikulu cha Wi-Fi 6 ndikupereka kulumikizana kokhazikika pazida zingapo nthawi imodzi.
5. Chitetezo chabwino
Tonse tikudziwa bwino kuti WPA3 inali kusintha kwakukulu m'zaka khumi izi. Ndi WPA3, obera amakhala ndi nthawi yovuta mosalekeza kulosera mapasiwedi. Ngakhale atakwanitsa kusokoneza mawu achinsinsi, zomwe amapeza sizingakhale zothandiza. Pofika pano, WPA3 ndiyosankha pazida zonse za Wi-Fi. Koma pa chipangizo cha Wi-Fi 6, WPA 3 ndiyofunika, kuti mupeze chiphaso cha Wi-Fi Alliance. Pulogalamu yopereka ziphaso ikangokhazikitsidwa, zikuyembekezeka kuti njira zolimba zachitetezo zidzakhazikitsidwa. Chifukwa chake, kukweza ku Wi-Fi 6 kumatanthauzanso kuti muli ndi chitetezo chabwinoko.

6. Kuchedwa kwafupika
Latency imatanthawuza kuchedwa kwa kutumiza kwa data. Ngakhale latency ndi vuto palokha, imayambitsanso mavuto ena monga kulumikizidwa pafupipafupi komanso nthawi yolemetsa. Wi-Fi 6 imayika data mu siginecha bwino kwambiri kuposa mtundu wakale. Chifukwa chake, latency imatsitsidwa.
7. Liwiro lalikulu
Chizindikiro chomwe chimatumiza deta chimadziwika kuti orthogonal frequency-division multiplexing (OFDM). Deta imagawidwa pakati pa zonyamulira zazing'ono kuti pakhale liwiro lalikulu (ndi 11% mwachangu). Pachifukwa ichi, kuphimba kumakulanso. Zida zonse zomwe zili m'nyumba mwanu, mosasamala kanthu za komwe zayikidwa, zidzalandira zizindikiro zamphamvu chifukwa cha kufalikira kwakukulu.
Beamforming
Beamforming ndi njira yomwe rauta imayang'ana chizindikiro pa chipangizo china ngati ipeza kuti chipangizocho chikukumana ndi zovuta. Ngakhale ma routers onse amachita bwino, rauta ya Wi-Fi 6 imakhala ndi mawonekedwe ochulukirapo. Chifukwa cha kuthekera kokuliraku, sipadzakhala malo akufa mnyumba mwanu. Izi limodzi ndi ODFM zimakupangitsani kuti mulumikizane ndi rauta kuchokera kulikonse mnyumba mwanu.
Kodi Wi-Fi 6 imathamanga bwanji?
Wi-Fi 5 inali ndi liwiro la 3.5 Gbps. Wi-Fi 6 imatengera ma notche angapo - liwiro loyembekezeka lamalingaliro limakhala pa 9.6 Gbps. Ndizodziwika bwino kuti kuthamanga kwamalingaliro sikufikira pakugwiritsa ntchito. Nthawi zambiri, liwiro lotsitsa ndi 72 Mbps / 1% ya liwiro lapamwamba kwambiri. Popeza 9.6 Gbps imatha kugawidwa pazida zamtaneti, liwiro la chipangizo chilichonse cholumikizidwa limakwera.
Chinthu chinanso choyenera kukumbukira ponena za liwiro lake ndi chakuti zimatengeranso zinthu zina. Kumalo komwe kuli zida zazikulu zolumikizira zida, kusintha kwa liwiro kumatha kuwonedwa mosavuta. M'kati mwa nyumba yanu, ndi zipangizo zochepa, zimakhala zovuta kuzindikira kusiyana kwake. Liwiro lochokera ku Internet Service Provider (ISP) limachepetsa rauta kuti isagwire ntchito mwachangu kwambiri. Ngati liwiro lanu likuchedwa chifukwa cha ISP yanu, rauta ya Wi-Fi 6 siyingakonze izi.
