802.11ax Kuchaziwe

I-WiFi6 entsha isekela imodi engu-802.11ax, ngakho-ke yini umehluko phakathi kwemodi engu-802.11ax ne-802.11ac?

Uma kuqhathaniswa ne-802.11ac, i-802.11ax iphakamisa ubuchwepheshe obusha bokuphindaphinda kwendawo, obungakwazi ukuhlonza nokuhlehlisa izingxabano zokusebenzelana komoya. Ngaleso sikhathi, ingakwazi ukuhlonza amasignali okuphazamisa ngendlela ephumelela kakhudlwana futhi inciphise ukuphazamiseka komsindo ofanayo ngokuhlolwa kwesiteshi okungenzi lutho nokulawula amandla ashukumisayo. Ngakho-ke, okuhlangenwe nakho okungenantambo eziteshini, ezikhumulweni zezindiza, emapaki, ezinkundleni zemidlalo nakwezinye izigcawu ezinabantu abaningi kuthuthukiswa kakhulu, futhi isilinganiso sokuphuma kuthiwa sifinyelela izikhathi ezingu-4 kunezinga le-802.11ac. Yethula isikimu sekhodi sokushintshwa kwe-oda eliphezulu 1024QAM. Uma kuqhathaniswa ne-256QAM ephakeme kakhulu ku-802.11ac, ukusebenza kahle kokuguqulwa kombhalo wekhodi kuphezulu. Izinga lokuhlobana lokusakaza kwesikhala somkhawulokudonsa ongu-80M ngamunye liyakhuphuka lisuka ku-433Mbps liye ku-600.4Mbps. 8 imifudlana yendawo) inyuke isuka ku-6.9Gbps ​​yaya ku-9.6Gbps, futhi izinga eliphezulu lokuhlobana lenyuke cishe ngo-40%. I-802.11ax isebenzisa ubuchwepheshe be-MU-MIMO obukhuphuka nobuya phansi nomfula ngokulandelana ukuze ithwale ukudluliswa kwabasebenzisi abaningi ngesikhathi esisodwa ngokusakaza okunezikhala eziningi kanye nama-subcarrier amaningi, okwandisa ukusebenza kahle kwesixhumi esibonakalayo somoya, kunciphisa ukubambezeleka kohlelo lokusebenza, futhi kunciphisa ukugwema ukungqubuzana kwabasebenzisi, kunikeze isiqinisekiso esingcono sokudlulisela ezimeni zabasebenzisi abaningi.
