WIFI5, okanyeIEEE 802.11ac, sisizukulwana sesihlanu iteknoloji yeLAN engenazingcingo. Yacetywa ngo-2013 kwaye isetyenziswe ngokubanzi kwiminyaka elandelayo. I-WIFI6, eyaziwa ngokubaIEEE 802.11ax(ekwaziwa ngokuba yi-WLAN Esebenzayo), ngumgangatho wesithandathu we-LAN engenazingcingo eqaliswe yi-WIFI Alliance ngo-2019. Xa kuthelekiswa ne-WIFI5, i-WIFI6 iye yafumana izinto ezininzi ezintsha zobuchwepheshe kunye nokuphuculwa.
2. Ukuphuculwa komsebenzi
2.1 Izinga eliphezulu lokudluliselwa kwedatha: I-WIFI6 isebenzisa iteknoloji yekhowudi ephezulu (efana ne-1024-QAM) kunye namajelo abanzi (ukuya kwi-160MHz), okwenza izinga eliphezulu lokudluliselwa kwethiyori liphezulu kakhulu kune-WIFI5, lifikelela kwi-9.6Gbps ngaphezulu.
2.2 I-latency ephantsi: I-WIFI6 iyanciphisa kakhulu i-latency yenethiwekhi ngokuzisa iteknoloji efana ne-TWT (i-Target Wake Time) kunye ne-OFDMA (i-Orthogonal Frequency Division Multiple Access), eyenza ukuba ifaneleke ngakumbi kwizicelo zonxibelelwano lwexesha langempela.
I-3.3 Ukusebenza kwe-concurrency ephezulu: I-WIFI6 isekela izixhobo ezininzi ukufikelela kunye nokunxibelelana ngexesha elinye. Ngokusebenzisa i-MU-MIMO (i-Multi-User Multiple Input Multiple Output) iteknoloji, idatha inokudluliselwa kwizixhobo ezininzi ngexesha elinye, ukuphucula ukugqithiswa ngokubanzi kwenethiwekhi. .
3. Ukuhambelana kwezixhobo
Izixhobo ze-WIFI6 zenza umsebenzi olungileyo ngokuhambelana ngasemva kwaye zinokuxhasa i-WIFI5 kunye nezixhobo zangaphambili. Nangona kunjalo, kufuneka kuqatshelwe ukuba izixhobo ze-WIFI5 azikwazi ukonwabela ukuphuculwa komsebenzi kunye neempawu ezintsha eziziswa yi-WIFI6.
4. Ukomelezwa kokhuseleko
I-WIFI6 yomeleze ukhuseleko, yazisa iprothokholi yoguqulelo lwe-WPA3, kwaye ibonelele ngokhuseleko oluluqilima lwegama lokugqitha kunye neendlela zokuqinisekisa. Ukongeza, i-WIFI6 ikwaxhasa izakhelo zolawulo ezifihliweyo, ngakumbi ukuphucula ukhuseleko lwenethiwekhi.
5. Iimpawu ezikrelekrele
I-WIFI6 yazisa iimpawu ezikrelekrele ngakumbi, njenge-BSS Coloring (i-Basic Service Set Coloring) iteknoloji, enokunciphisa ngokufanelekileyo ukuphazamiseka phakathi kwezibonakaliso ezingenazintambo kunye nokuphucula ukuzinza kwenethiwekhi. Ngelo xesha, i-WIFI6 iphinde ixhase izicwangciso zokulawula amandla ezikrelekrele ngakumbi, njengeXesha leThagethi yokuVuka (TWT), enokunciphisa ukusetyenziswa kwamandla kwesixhobo.
6. Ukusetyenziswa kakuhle kwamandla
I-WIFI6 iphinde yenze uphuculo ekusebenziseni amandla. Ngokuzisa ukumodareyitha okusebenzayo ngakumbi kunye nobuchwepheshe beekhowudi (ezifana ne-1024-QAM) kunye nezicwangciso zokulawula amandla ahlakaniphile (ezifana ne-TWT), izixhobo ze-WIFI6 zinokulawula ngcono ukusetyenziswa kwamandla kunye nokwandisa ubomi bebhetri yesixhobo ngelixa ugcina ukusebenza okuphezulu.
Isishwankathelo: Xa kuthelekiswa ne-WIFI5, i-WIFI6 inokuphuculwa okubalulekileyo kwiinkalo ezininzi, kubandakanywa izinga eliphezulu lokudluliselwa kwedatha, i-latency ephantsi, ukusebenza kwe-concurrency ephezulu, ukhuseleko olunamandla, iimpawu ezikrelekrele ngakumbi kunye nokuSebenzisa kakuhle kwamandla. Olu phuculo lwenza ukuba i-WIFI6 ifaneleke ngakumbi kwiindawo zale mihla ze-LAN ezingenazingcingo, ngakumbi kwiimeko ezixinzelelekileyo kunye ne-high-concurrency application.
