Umahluko phakathi kwe-WIFI5 kunye ne-WIFI6

 1.IProtokholi yoKhuseleko lweNethiwekhi

Kwinethiwekhi engenazingcingo, ukubaluleka kokhuseleko lwenethiwekhi akunakugxininiswa kakhulu.I-Wifi yinethiwekhi engenazingcingo evumela izixhobo ezininzi kunye nabasebenzisi ukuba baqhagamshele kwi-Intanethi ngendawo yokufikelela enye.I-Wifi ikwasetyenziswa kwiindawo zikawonke-wonke, apho kunolawulo oluncinci kulowo unokuqhagamshela kwinethiwekhi.Kwizakhiwo ezihlangeneyo, ulwazi oluyimfuneko kufuneka lukhuselwe kwimeko yokubambisa ii-hackers ezinobuchule bazama ukutshabalalisa okanye ukweba idatha.

I-Wifi 5 ixhasa iiprotocol zeWPA ne-WPA2 zonxibelelwano olukhuselekileyo.Olu luphuculo oluthile lokomeleza kulo mgaqo-nkqubo we-WEP ngoku, kodwa ngoku unengozi kunye nobuthathaka.Esona siguli sikuhlasele isichazi-magama, apho i-cybercritis inokuxela iphasiwedi yakho efihliweyo enemizamo emininzi kunye nendibaniselwano.

I-Wifi 6 ixhotywe ngenkqubo yokhuseleko lokhuseleko WPA3.Ke ngoko, izixhobo ezixhasa uWifi 6 Sebenzisa i-WPA, WPA2, kunye neeprotocols ze-WPA3 ngaxeshanye.I-Wifi iKhuselela ukufikelela kwi-3 ephuculweyo yokuqinisekiswa kweenkqubo ezininzi zokuqinisekisa kunye neenkqubo zokufihla.I-one iteknoloji ethintela ngokuzenzekelayo i-opection ngokuzenzekelayo, kwaye ekugqibeleni, iskeyikhi okanye iikhowudi ziqhagamshelwe ngqo kwisixhobo.

2.Isantya sokuhambisa idatha

Isantya sisibonisi esibalulekileyo nenomdla kuba itekhnoloji entsha kufuneka idilesi ngaphambi kokuba ikhutshwe.Isantya sibalulekile kuyo yonke into eyenzekayo kwi-Intanethi nakuluphi uhlobo lwenethiwekhi.Amaxabiso akhawulezayo athetha amaxesha amafutshane wokukhuphela, ukusasaza okungcono, ukutshintshelwa kwedatha ngokukhawuleza, ividiyo engcono kunye nengqungquthela yevidiyo, ukukhangela ngokukhawuleza okukhawulezileyo nangaphezulu.

I-wifi 5 inesantya esiphezulu sedatha ye-6.9 ye-GBPS.Kubomi bokwenyani, isantya sokudlulisela idatha yedatha ye-802.11AC imalunga ne-200bps.Ixabiso apho i-WiFi esemgangathweni isebenza khona kwi-QAM (i-QuadetutyAtux imodyuli) kunye nenani lezixhobo ezinxulumene nendawo yokufikelela okanye i-router.I-wifi 5 isebenzisa i-256-Quid yolawulo lwe-256, ephantsi kakhulu kune-wifi 6. Ukongeza, i-WiFi 5 i-WU-MU-MU-MU-MUIM ivumela unxibelelwano ngaxeshanye lwezixhobo ezine.Izixhobo ezingakumbi zithetha ukuxinana kunye ne-bandwidth yokwabelana, okukhokelela kwisantya esicothayo kwisixhobo ngasinye.

Ngokwahlukileyo, i-Wifi 6 yeyona ndlela ilungileyo malunga nesantya, ngakumbi ukuba inethiwekhi izele.Isebenzisa i-1024-Quarty Modration yenqanaba eliphezulu lokuhambisa i-theoretical elona liphezulu ukuya kwi-9.6GBps.I-Wi-Fi 5 kunye ne-I-SI-FI 6 SI-6 AKUFUNI UKUVUNYELWA KUSETYENZISIWEYO KWISITHUBA.I-Wifi 6 ihlala ikhawuleza, kodwa intsingiselo yokwenyani ixakile xa izixhobo ezininzi ziqhagamshelwe kwinethiwekhi ye-WIFI.Inani elichanekileyo lezixhobo ezixhunyiweyo ezibangela ukuba kwenziwe isantya kwisantya kunye namandla e-Intanethi yezixhobo ezi-5 ze-Wifi, kunye neendlela xa usebenzisa i-WiFi 6 akunakuqatshelwa.

3. Indlela yeBeam

I-Beam Forting yindlela yokuhambisa umqondiso esalathisa uphawu olungenazingcingo kumsebenzi othile, kunokuba usasaze umqondiso ukusuka kwicala elahlukileyo.Ukusebenzisa umbane, indawo yokufikelela inokuthumela idatha ngqo kwisixhobo endaweni yokusasaza umqondiso kuwo onke umkhombandlela.I-Beam Eyokwakhiwa ayisiyo itekhnoloji entsha kwaye inezicelo zombini i-wifi 4 kunye ne-wifi 5. Kwimigangatho emi-5 ye-WiFi, i-antennas ezine isetyenziswa.I-Wifi 6, nangona kunjalo, isebenzisa i-eriyali esibhozo.Okungcono ukukwazi ukusebenzisa itekhnoloji yokwakha i-Bheam, kungcono kwinqanaba ledatha kunye noluhlu lomqondiso.

4. I-Orthodonal Frequety iCandelo lofikelelo oluninzi (lwe-Ofdma)

I-wifi 5 isebenzisa itekhnoloji ebizwa ngokuba yi-Orthogonal ye-Orthogon ye-Orthodoning Counting (ye-OFDM) yolawulo lokufikelela kwinethiwekhi.Yindlela yokulawula inani labasebenzisi abafikelela kwisiseko esithile ngexesha elithile.Kumgangatho we-802.11AC, i-20mhz, i-40mhz, i-80mhz kunye ne-160mhz kunye ne-160mhz kunye ne-120mhz, i-128 ye-Subarchriers, i-512 ngokwahlukeneyo kunye ne-512.Oku kuthintela kakhulu inani labasebenzisi abanokuqhagamshela kwaye basebenzise inethiwekhi ye-WIFI ngexesha elinikiweyo.

I-Wifi 6, kwelinye icala, isebenzisa i-Ordma (i-Orthogonal ye-Orthogonal iCandelo lokufikelela).Itekhnoloji ye-Ordma ikhulisa indawo ekhoyo ye-suricarve kwibhendi engaphakathi.Ngokwenza oku, abasebenzisi akufuneki balinde emgceni womntu ophetheyo simahla, kodwa unokufumana ngokulula.

I-Ordma yabelana ngeeyunithi ezahlukeneyo zezixhobo kubasebenzisi abaninzi.I-Ordma ifuna izihlandlo ezine njengamazantsi e-sublenerd nganye nganye yejelo njengetekhnoloji yangaphambili.Oku kuthetha ukuba kwi-20mhz, i-40mhz, i-80mhz, kunye ne-160mhz, i-160mhz, i-802 ye-802.11ax ine-256, i-548, kunye ne-2048.Oku kunciphisa ukuxinana kunye nolwazelelo, nokuba uqhagamshela izixhobo ezininzi.I-Ordma iphucula ukusebenza ngempumelelo kwaye inciphisa i-tency, iyenza ilungele imisebenzi yebhendi ephantsi.

5. I-5 yeendlela ezininzi zokungenisa izinto ezininzi (i-mu-mimo)

I-mu mimo imela "umsebenzisi oninzi, igalelo elininzi, iziphumo ezininzi".Itekhnoloji engenazingcingo evumela abasebenzisi abaninzi ukuba banxibelelane ne-router ngaxeshanye.Ukusuka kwi-wifi 5 ukuya kwi-Wifi 6, amandla e-mu mimo ukwahluke kakhulu.

I-wifi 5 isebenzisa i-DOPLICK, indlela enye 4 × 4 mu-mimo.Oku kuthetha ukuba abasebenzisi abaninzi abanemida ethile banokufikelela kwi-router kunye nonxibelelwano oluzinzileyo lwe-wifi.Nje ukuba kubekho umda we-4 Uhlangulo ngaxeshanye, i-wifi idityanisiwe kwaye iqala ukubonisa iimpawu zokuxinana, njengokulahleka kwendlela, ilahleko yepakethi, njl.

I-Wifi 6 isebenzisa i-8 × 8 mu mimo teknoloji.Oku kungasingatha izixhobo ezi-8 ezinxulumene nokusetyenziswa okusebenzayo kwe-lan engenazingcingo ngaphandle kokuphazamiseka.Kungcono, i-WiFi 6 MU Mimo Pidirectialal, intsingiselo ye-PAIPheloral iyakwazi ukuqhagamshela kwi-router kwi-router yamaxesha amaninzi.Oku kuthetha ukuba amandla okuphuculwa kokufaka ulwazi kwi-Intanethi, phakathi kwezinye izinto.

6. Iibhendi ezi-8

Umahluko omnye ocacileyo phakathi kwe-wifi 5 kunye ne-Wifi 6 ngamanqanaba ashushu eetekhnoloji ezimbini.I-Wifi 5 isebenzisa kuphela i-5Ghz band kwaye iphazamisane.Ukungancedi kakuhle kukuba uluhlu lomqondiso lumfutshane kwaye amandla okuvula iindonga kunye neminye imiqobo incitshisiwe.

I-Wifi 6, kwelinye icala, isebenzisa i-frequeges ezimbini, umgangatho we-2.4gz kunye ne-5Ghz.Kwi-Wifi 6e, abaphuhlisi baya kongeza iqela le-6gz ukuya kwi-Wifi 6.I-Wifi 6 isebenzisa zombini i-2.4gz kunye ne-5gzbos, okuthetha ukuba izixhobo zinokusondela ngokuzenzekelayo kwaye zisebenzise eli bandi ngophazamiso oluncinci kunye nokusetyenziswa okungcono.Ngale ndlela, abasebenzisi bafumana ezona thuna zilungileyo, kunye nezantya ezikhawulezayo ezikuluhlu olusondeleyo kunye noluhlu olubanzi xa ii-Piapherals azikho kwindawo enye.

7. Ukufumaneka kwemibala ye-BSS

I-BSS Imibala yenye into ye-wifi 6 eyayibeka ngaphandle kwezizukulwana ezidlulileyo.Le yinto entsha yomgangatho we-WiFi 6.I-BSS, okanye iseti yenkonzo esisiseko, ngokwayo iyinxalenye yenethiwekhi nganye ye-802.11.Nangona kunjalo, izizukulwane kuphela ze-wifi ezi-6 kunye nezazi ezizayo ziya kuba nakho ukuthathela ingqalelo imibala yeBSS kwezinye izixhobo ezisebenzisa izikhombisi zombala we-BSS.Eli nqaku libalulekile kuba liyanceda ukukhusela imiqondiso ekubeni igqunywe.

8. Umahluko wexesha le-Incubation

U-Latency ubhekisa kulibaziseko kusulelo lweepakethi ukusuka kwenye indawo ukuya kwenye.Isantya sokulibaziseka esisezantsi esikufutshane ne-zero silungile okanye sibonisa ukulibaziseka kancinci.Xa kuthelekiswa ne-wifi 5, i-Wifi 6 inomsindo omkhulu, iyenza ilungele ishishini kunye neshishini.Abasebenzisi basekhaya baya kuthanda le nqaku kwiimodeli ze-wifi zamva nje, njengoko zithetha ngokukhawulezaUnxibelelwano lwe-ternet.
