Wi-fi 6E ndi njira yatsopano yogwiritsira ntchito ukadaulo wa Wi-Fi 6. “E” imayimira “Extended,” ndikuwonjezera gulu latsopano la 6GHz ku magulu oyambilira a 2.4ghz ndi 5Ghz. Mu kotala yoyamba ya 2020, Broadcom idatulutsa zotsatira zoyeserera zoyambirira za Wi-Fi 6E ndikutulutsa chipset yoyamba padziko lonse ya wi-fi 6E BCM4389. Pa Meyi 29, Qualcomm idalengeza chip ya Wi-Fi 6E yomwe imathandizira ma rauta ndi mafoni.
Wi-fi Fi6 ikutanthauza ukadaulo wa netiweki yopanda zingwe wa m'badwo wachisanu ndi chimodzi, womwe uli ndi liwiro lolumikizana ndi intaneti nthawi 1.4 kuposa m'badwo wachisanu. Kachiwiri, kupanga zatsopano zaukadaulo, kugwiritsa ntchito ukadaulo wa OFDM orthogonal Frequency division multiplexing ndi ukadaulo wa MU-MIMO, zimathandiza Wi-Fi 6 kupereka chidziwitso chokhazikika cha kulumikizana ndi netiweki pazida ngakhale pazida zambiri zolumikizirana ndikusunga ntchito ya netiweki yosalala.
Zizindikiro zopanda zingwe zimatumizidwa mkati mwa sipekitiramu yosadziwika bwino yomwe yaperekedwa ndi lamulo. Mibadwo itatu yoyamba ya ukadaulo wopanda zingwe, WiFi 4, WiFi 5 ndi WiFi 6, imagwiritsa ntchito ma band awiri a zizindikiro, monga momwe chithunzi chili pansipa. Chimodzi ndi band ya 2.4ghz, yomwe ili pachiwopsezo chosokonezedwa ndi zida zambiri, kuphatikiza ma baby monitors ndi ma microwave ovens. Wina, band ya 5GHz, tsopano yatsekedwa ndi zida ndi ma network achikhalidwe a Wi-Fi.
Njira yosungira mphamvu ya TWT (TargetWakeTime) yomwe idayambitsidwa ndi protocol ya WiFi 6 802.11ax ili ndi kusinthasintha kwakukulu, zomwe zimathandiza kuti magetsi azigwiritsidwa ntchito nthawi yayitali, komanso nthawi yogona pazida zambiri. Nthawi zambiri, ili ndi zabwino izi:
1. AP imakambirana ndi chipangizocho ndipo imasankha nthawi yeniyeni yolumikizirana ndi media.
2. Kuchepetsa mikangano ndi kusagwirizana pakati pa makasitomala;
3. Wonjezerani kwambiri nthawi yogona ya chipangizochi kuti muchepetse kugwiritsa ntchito mphamvu.
Momwe Wi-Fi 6 imagwirira ntchito ndi yofanana ndi ya 5G. Ndi yoyenera kugwiritsa ntchito liwiro lapamwamba, mphamvu zambiri, komanso nthawi yochepa yochedwetsa, kuphatikizapo zinthu monga mafoni anzeru, mapiritsi, malo atsopano anzeru monga nyumba zanzeru, mapulogalamu apamwamba kwambiri, ndi VR/AR. Zinthu monga chithandizo chamankhwala chakutali cha 3D; Zinthu zokhala ndi anthu ambiri monga ma eyapoti, mahotela, malo akuluakulu, ndi zina zotero. Zinthu monga mafakitale anzeru, nyumba zosungiramo zinthu zopanda anthu, ndi zina zotero.
Popangidwa kuti igwirizane ndi dziko lomwe chilichonse chikugwirizana, Wi-Fi 6 imawonjezera mphamvu yotumizira mauthenga ndi liwiro poganizira kuchuluka kwa ma uplink ndi downlink. Malinga ndi lipoti la Wi-Fi Alliance, mtengo wa WiFi padziko lonse lapansi unali madola 19.6 thililiyoni aku US mu 2018, ndipo akuti mtengo wa WiFi padziko lonse lapansi pazachuma cha mafakitale udzafika madola 34.7 thililiyoni aku US pofika chaka cha 2023.
Gawo la mabizinesi pamsika wa WLAN linakula kwambiri mu kotala lachiwiri la 2021, likukula ndi 22.4 peresenti pachaka kufika pa $1.7 biliyoni, malinga ndi lipoti la IDC la padziko lonse la Wireless Local Area Networks (WLAN) lotsata kotala. Mu gawo la ogula pamsika wa WLAN, ndalama zinatsika ndi 5.7% mu kotala kufika pa $2.3 biliyoni, zomwe zinapangitsa kuti ndalama zonse zomwe amapeza ziwonjezeke ndi 4.6% chaka ndi chaka mu kotala lachiwiri la 2021.
Pakati pa izi, zinthu za Wi-Fi 6 zinapitiliza kukula pamsika wa ogula, zomwe zinapanga 24.5 peresenti ya ndalama zonse zomwe ogula amapeza, kuchokera pa 20.3 peresenti mu kotala loyamba la 2021. Malo olowera a WiFi 5 adapangabe ndalama zambiri (64.1%) ndi kutumiza mayunitsi (64.0%).
Wi-fi 6 ili kale ndi mphamvu, koma chifukwa cha kufalikira kwa nyumba zanzeru, chiwerengero cha zipangizo zomwe zili m'nyumba zomwe zimalumikizidwa ndi opanda zingwe chikuwonjezeka kwambiri, zomwe zingayambitse kuchulukana kwa ma band a 2.4ghz ndi 5GHz, zomwe zimapangitsa kuti Wi-Fi ikhale yovuta kufika pamlingo wake wonse.
Kuneneratu kwa IDC kwa kukula kwa maulumikizidwe a intaneti ku China m'zaka zisanu kukuwonetsa kuti maulumikizidwe a waya ndi WiFi ndi omwe ali ndi gawo lalikulu kwambiri la maulumikizidwe amitundu yonse. Chiwerengero cha maulumikizidwe a waya ndi WiFi chinafika 2.49 biliyoni mu 2020, chomwe chimapanga 55.1 peresenti ya zonse, ndipo chikuyembekezeka kufika 4.68 biliyoni pofika chaka cha 2025. Pakuwunika makanema, iot yamafakitale, nyumba zanzeru ndi zina zambiri, maulumikizidwe a waya ndi WiFi adzagwirabe ntchito yofunika kwambiri. Chifukwa chake, kukwezedwa ndi kugwiritsidwa ntchito kwa WiFi 6E ndikofunikira kwambiri.
Bandi yatsopano ya 6Ghz ndi yopanda ntchito, zomwe zimapangitsa kuti magetsi aziyenda bwino. Mwachitsanzo, msewu wodziwika bwino ukhoza kugawidwa m'njira zinayi, njira zisanu ndi chimodzi, njira zisanu ndi zitatu, ndi zina zotero, ndipo magetsi ali ngati "njira" yomwe imagwiritsidwa ntchito potumiza ma signali. Zinthu zambiri zogwiritsa ntchito magetsi zimatanthauza "njira" zambiri, ndipo mphamvu yotumizira magetsi idzawonjezeka moyenerera.
Nthawi yomweyo, gulu la 6GHz limawonjezedwa, lomwe lili ngati mtsinje wodutsa msewu womwe uli kale wodzaza anthu, zomwe zimapangitsa kuti kuyenda bwino kwa msewu wonse kuwonjezeke. Chifukwa chake, pambuyo poti gulu la 6GHz layamba kugwiritsa ntchito, njira zosiyanasiyana zoyendetsera ma spectrum a Wi-Fi 6 zitha kukhazikitsidwa bwino komanso mokwanira, ndipo kulumikizana kumakhala kokwera, motero kumapereka magwiridwe antchito apamwamba, mphamvu yogwira ntchito bwino komanso kuchedwa kochepa.
Pa mlingo wa ntchito, WiFi 6E imathetsa vuto la kuchulukana kwa ma band a 2.4ghz ndi 5GHz. Kupatula apo, pali zida zambiri zopanda zingwe m'nyumba tsopano. Ndi 6GHz, zida zomwe zimafuna intaneti zimatha kulumikizana ndi band iyi, ndipo ndi 2.4ghz ndi 5GHz, kuthekera kwakukulu kwa WiFi kumatha kuchitika.
Si zokhazo, komanso WiFi 6E ilinso ndi mphamvu yaikulu pa chip ya foni, yokhala ndi liwiro la 3.6Gbps, kuwirikiza kawiri kuposa chip ya WiFi 6. Kuphatikiza apo, WiFi 6E ili ndi kuchedwa kochepa kwa zosakwana ma millisecond atatu, komwe ndi kocheperako nthawi zoposa 8 kuposa mbadwo wakale m'malo odzaza. Itha kupereka chidziwitso chabwino pamasewera, makanema apamwamba, mawu ndi zina.
