WiFi 6 vs WiFi 5 liwiro: Chabwino n'chiti?

Mu 2018, WiFi Alliance idalengeza WiFi 6, m'badwo watsopano, wachangu wa WiFi womwe umapangidwa kuchokera kumapangidwe akale (ukadaulo wa 802.11ac).Tsopano, titayamba kutsimikizira zida mu Seputembala wa 2019, yafika ndi njira yatsopano yopangira mayina yomwe ndiyosavuta kumvetsetsa kuposa dzina lakale.

Tsiku lina posachedwa, zida zathu zambiri zolumikizidwa zidzathandizidwa ndi WiFi 6.Mwachitsanzo, Apple iPhone 11 ndi Samsung Galaxy Notes zimathandizira kale WiFi 6, ndipo tawonapo ma routers a Wi-Fi CERTIFIED 6™ akutuluka posachedwa.Kodi tingayembekezere chiyani ndi muyezo watsopano?

 

Ukadaulo watsopanowu umapereka zosintha zamalumikizidwe pazida zoyatsidwa ndi WiFi 6 ndikusunga zobwerera kumbuyo kwa zida zakale.Zimagwira ntchito bwino m'malo okhala ndi kachulukidwe kwambiri, zimathandizira kuchuluka kwa zida, zimathandizira moyo wa batri pazida zomwe zimagwirizana, ndipo imadzitamandira ndi mitengo yotumizira ma data kuposa yomwe idayamba kale.

Pano pali kufotokozedwa kwa miyezo yam'mbuyomu.Zindikirani kuti matembenuzidwe akale adasankhidwa ndi masinthidwe osinthidwa, komabe, sagwiritsidwanso ntchito kwambiri:

WiFi 6kuzindikira zida zomwe zimathandizira 802.11ax (yotulutsidwa 2019)

WiFi 5kuzindikira zida zomwe zimathandizira 802.11ac (yotulutsidwa 2014)

WiFi 4kuzindikira zida zomwe zimathandizira 802.11n (yotulutsidwa 2009)

WiFi 3kuzindikira zida zomwe zimathandizira 802.11g (yotulutsidwa 2003)

WiFi 2kuzindikira zida zomwe zimathandizira 802.11a (yotulutsidwa 1999)

WiFi 1kuzindikira zida zomwe zimathandizira 802.11b (yotulutsidwa 1999)

WiFi 6 vs WiFi 5 liwiro

Choyamba, tiyeni tilankhule zongoyerekeza.Monga momwe Intel ananenera, "Wi-Fi 6 imatha kutulutsa 9.6 Gbps kudutsa njira zingapo, poyerekeza ndi 3.5 Gbps pa Wi-Fi 5."Mwachidziwitso, rauta ya WiFi 6 imatha kugunda mwachangu kuposa 250% mwachangu kuposa zida zaposachedwa za WiFi 5.

Kutha kwa liwiro la WiFi 6 ndi chifukwa chaukadaulo monga orthogonal frequency division multiple access (OFDMA);MU-MIMO;beamforming, yomwe imapangitsa kuti mitengo ikuluikulu ya data pamitundu yoperekedwa iwonjezere kuchuluka kwa maukonde;ndi 1024 quadrature amplitude modulation (QAM), yomwe imawonjezera kutulutsa kwazomwe zikubwera, zogwiritsa ntchito kwambiri bandwidth mwa encoding zambiri mu kuchuluka komweko kwa sipekitiramu.

Ndipo pali WiFi 6E, nkhani yabwino ya kuchulukana kwa maukonde

Kuwonjezera kwina kwa WiFi "kusintha" ndi WiFi 6E.Pa Epulo 23, FCC idapanga chisankho chambiri chololeza kuwulutsa popanda chilolezo pagulu la 6GHz.Izi zimagwira ntchito mofanana ndi momwe rauta yanu kunyumba ingawululire pamagulu a 2.4GHz ndi 5GHz.Tsopano, zida za WiFi 6E zili ndi gulu latsopano lokhala ndi njira zatsopano za WiFi kuti muchepetse kuchuluka kwa maukonde ndi ma siginecha otsika:

"6 GHz imayankhira kusowa kwa ma Wi-Fi popereka zotchingira zowoneka bwino kuti zizikhala ndi ma tchanelo 14 owonjezera a 80 MHz ndi ma tchanelo 7 owonjezera a 160 MHz omwe amafunikira pakugwiritsa ntchito ma bandwidth apamwamba omwe amafunikira kutulutsa kwa data mwachangu monga kutsatsira makanema otanthauzira komanso zenizeni zenizeni. . Zida za Wi-Fi 6E zithandizira ma tchanelo okulirapo komanso mphamvu zowonjezera kuti zithandizire kwambiri pamanetiweki."- WiFi Alliance

Lingaliroli limachulukitsa pafupifupi kanayi kuchuluka kwa bandwidth yomwe ikupezeka pakugwiritsa ntchito kwa WiFi ndi zida za IoT—1,200MHz ya sipekitiramu mu bandi ya 6GHz yomwe ikupezeka kuti igwiritsidwe ntchito popanda chilolezo.Kuti izi zitheke, magulu a 2.4GHz ndi 5GHz ophatikizidwa pakali pano akugwira ntchito mkati mwa 400MHz ya sipekitiramu yopanda chilolezo.
