802.11ax Icacisiwe

I-WiFi6 entsha isekela imodi ye-802.11ax, ngoko yintoni umehluko phakathi kwe-802.11ax kunye ne-802.11ac mode?

Xa kuthelekiswa ne-802.11ac, i-802.11ax iphakamisa iteknoloji entsha ye-multiplexing yendawo, enokuchonga ngokukhawuleza kwaye ibuyise iingxabano zomoya. Ngeli xesha, inokuchonga imiqondiso yongenelelo ngempumelelo ngakumbi kwaye inciphise ukuphazamiseka kwengxolo efanayo ngovavanyo oluguquguqukayo lwesiteshi esingasebenziyo kunye nolawulo lwamandla aguqukayo. Ngaloo ndlela, amava angenazintambo kwizikhululo, kwizikhululo zeenqwelo-moya, kwiipaki, kwibala lezemidlalo nakwezinye iindawo ezinoxinano oluphezulu ziphuculwe kakhulu, kwaye umyinge ophakathi kuthiwa ufikelela kumaxesha e-4 kumgangatho we-802.11ac. Yazisa iskimu sokumodareyitha somyalelo ophezulu we-1024QAM. Xa kuthelekiswa neyona 256QAM iphezulu kwi-802.11ac, ukusebenza kakuhle kwe-encoding modulation kuphezulu. Izinga lokulungelelaniswa kwendawo nganye ye-80M ye-bandwidth yokwandisa ukusuka kwi-433Mbps ukuya kwi-600.4Mbps. I-8 imilambo yendawo) inyuke ukusuka kwi-6.9Gbps ​​ukuya kwi-9.6Gbps, kwaye izinga eliphezulu lokulungelelanisa linyuke phantse nge-40%. I-802.11ax isebenzisa i-MU-MIMO enyukayo nasezantsi kunye ne-teknoloji ye-OFDMA enyukayo nasezantsi ngokulandelelana ukuthwala ukuhanjiswa kwabasebenzisi abaninzi kunye nemijelo yeendawo ezininzi kunye ne-multi-subcarriers, eyandisa ukusebenza kakuhle kwe-interface yomoya, ukunciphisa ukulibaziseka kwesicelo, kwaye kwakhona. kunciphisa ukuphepha ukungqubana kwabasebenzisi, ukubonelela ngesiqinisekiso esingcono sothumelo kwiimeko zabasebenzisi abaninzi.
