Umehluko phakathi kwe-WIFI5 ne-WIFI6

 1.Iphrothokholi Yokuphepha Kwenethiwekhi

Kumanethiwekhi angenantambo, ukubaluleka kokuphepha kwenethiwekhi akunakugcizelelwa.I-Wifi inethiwekhi engenantambo evumela amadivayisi nabasebenzisi abaningi ukuthi baxhume ku-inthanethi ngendawo eyodwa yokufinyelela.I-WiFi nayo isetshenziswa kaningi ezindaweni zomphakathi, lapho kulawulwa khona okuncane ukuthi ngubani ongaxhuma kwinethiwekhi.Ezakhiweni ezihlanganisiwe, imininingwane edingekayo idinga ukuvikeleka kubaduni abanonya bazama ukucekela phansi noma ukweba idatha.

I-WiFi 5 isekela amaphrothokholi we-WPA ne-WPA2 ukuze uxhumane ophephile.Lokhu kungukuthuthuka okubalulekile kwezokuphepha ngaphezulu kwephrothokholi ye-WeP ephelelwe yisikhathi esedlule, kepha manje kunekhono eziningana nobuthakathaka.Elinye isengozini elinjalo kungukuhlaselwa kwesichazamazwi, lapho ama-cybercriminals angabikezela iphasiwedi yakho ebhalwe ngemfihlo ngemizamo eminingi kanye nezinhlanganisela.

I-WiFi 6 ifakwe nge-WPA3 yezokuphepha yakamuva.Ngakho-ke, amadivayisi axhasa i-WiFi 6 Sebenzisa ama-protocol e-WPA, WPA2, kanye ne-WPA3 ngasikhathi sinye.Ukufinyelela okuvikelwe i-WiFi okungu-3 okuthuthukisiwe kokuqinisekiswa kwe-multi-factor kanye nezinqubo zokubethela.Kune-Ole Technology evimbela ukubethelwa okuzenzakalelayo, futhi ekugcineni, ukuskena noma amakhodi axhunyiwe ngqo kudivayisi.

2.Ijubane lokuhambisa idatha

Ijubane liyisici esibalulekile futhi esijabulisayo sokuthi ubuchwepheshe obusha okufanele bubhebhetheke ngaphambi kokuthi bakhishwe.Ijubane libalulekile kukho konke okwenzeka kwi-Intanethi nanoma yiluphi uhlobo lwenethiwekhi.Amanani asheshayo asho izikhathi zokulanda ezimfishane, ukusakazwa okungcono, ukudluliswa kwedatha okusheshayo, ividiyo engcono kanye nokungqubuzana kwezwi, ukuphequlula okusheshayo nokuningi.

I-WiFi 5 inesivinini esikhulu sokudlulisa idatha ye-theoretical of 6.9 GBPS.Empilweni yangempela, ijubane lokudlulisa idatha eliphakathi kwe-802.11AC Standard cishe ngo-200MBPS.Izinga elijwayelekile lapho i-WiFi lisebenza ngalo lincike ku-Qam (Quadrature Amplitude Modulant) kanye nenombolo yamadivayisi axhunywe endaweni yokufinyelela noma i-router.I-WiFi 5 isebenzisa ukuguquguquka kwe-256-Qam, okuphansi kakhulu kune-WiFi 6. Ngaphezu, ubuchwepheshe be-WiFi 5 Mu-Mimo buvumela ukuxhumeka kwamadivayisi amane.Amadivaysi amaningi asho ukuxubana kanye nokwabelana nge-bandwidth, okuholela ekushiseni okuhamba kancane kwedivayisi ngayinye.

Ngokuphambene, i-WiFi 6 iyisinqumo esingcono ngokwesivinini, ikakhulukazi uma inethiwekhi igcwele.Isebenzisa ukuguquguquka kwe-1024-Qam kokushintshana kwe-theor tooretical ration ration kufinyelela ku-9.6GBPS.I-Wi-Fi 5 ne-Wi-Fi 6 isivinini asiyeki okuningi kusuka kudivayisi kuya kudivayisi.I-WiFi 6 ihlala ishesha, kepha inzuzo yangempela yejubane yilapho amadivayisi amaningi exhunywe kwinethiwekhi ye-WiFi.Inani eliqondile lamadivayisi axhunyiwe abangela ukwehla okubalulekile kusivinini nangamandla e-Intanethi amadivaysi ama-WiFi ama-5 lapho usebenzisa i-WIFI 6 ngeke kuqashelwe.

3. Indlela yokwehla kwakhiwa

I-Beam Ezakhemeni inqubo yokuhambisa isiginali eqondisa isiginali engenantambo esivumelwaneni esithile, kunokuba isatshalaliswe isiginali kusuka endaweni ehlukile.Usebenzisa i-Beangforming, indawo yokufinyelela ingathumela idatha ngqo kudivayisi esikhundleni sokusakaza isinali kuzo zonke izinkomba.U-Beam Ukwenza ubuchwepheshe obusha futhi unezicelo ku-WiFi 4 ne-WiFi 5. Ku-WiFi 5 ejwayelekile, kusetshenziswa kuphela izimpondo ezine.I-WiFi 6, nokho, isebenzisa izimpondo eziyisishiyagalombili.Ikhono le-WiFi router lokusebenzisa ubuchwepheshe be-beam ekwakheni, okungcono inani ledatha nobubanzi besiginali.

4. I-Orthogonal Frequency Division Division Multiple Access (ofdma)

I-WiFi 5 isebenzisa ubuchwepheshe obubizwa nge-Orthogonal Frequency Divising MultenityXing Multiplexing (ofdm) ngokulawulwa kokufinyelela kwenethiwekhi.Kuyindlela yokulawula inani labasebenzisi abangena endaweni ethile engaphansi ngesikhathi esithile.Ku-802.11AC ejwayelekile, i-20mhz, 40mhz, 80mhz band banama-subcardier angama-64, ama-subcarriers angama-256 kanye nama-subcarrier angama-512 ngokulandelana.Lokhu kukhawulela kakhulu inani labasebenzisi abangakwazi ukuxhumana nokusebenzisa inethiwekhi ye-wifi ngesikhathi esithile.

I-WiFi 6, ngakolunye uhlangothi, isebenzisa i-Ordma (i-Orthogonal Frequency Division Ukufinyelela Multiple).Ubuchwepheshe be-Ofdma buningi isikhala esikhona esisezingeni eliphansi kubhendi efanayo yemvamisa.Ngokwenza lokhu, abasebenzisi akudingeki balinde emgqeni we-Free Sub-Carriers, kepha bangathola kalula.

I-Ofdma arocates amayunithi ehlukene izinsiza kubasebenzisi abaningi.I-OFMA idinga amahlandla amane ama-subcarriers amaningi ngokuvama kwesiteshi njengobuchwepheshe bangaphambilini.Lokhu kusho ukuthi ku-20mhz, 40mhz, 80mhz, neziteshi eziyi-160mhz, i-802.111 standard inama-256, 512, 1024, kanye nama-2048 subcarriers ngokulandelana.Lokhu kunciphisa ukugcwala kanye ne-latency, noma ngabe kuxhuma amadivayisi amaningi.I-OftMA ithuthukisa ukusebenza kahle futhi yehlise i-latency, okwenza kube kuhle ngokusebenza komkhawulokudonsa okuphansi.

5. Umsebenzisi Multiple Out Multiple Output Multiple Output (Mu-Mimo)

UMu Mimo umele "umsebenzisi omningi, okokufaka okuningi, okukhipha okuningi".Kuwubuchwepheshe obungenawaya obuvumela abasebenzisi abaningi ukuthi bakwazi ukuxhumana ne-router ngasikhathi sinye.Ukusuka kwi-WiFi 5 kuya ku-WiFi 6, umthamo we-MU MIMO uhlukile kakhulu.

I-WiFi 5 isebenzisa ukwehla kwe-Downlink, ngandlela thile 4 × 4 4 mu-mimo.Lokhu kusho ukuthi abasebenzisi abaningi abanemikhawulo ethile bangafinyelela i-router kanye nokuxhumeka kwe-wifi ezinzile.Lapho umkhawulo we-4 ukuhanjiswa kanyekanye udluliwe, i-WiFi iyaqhubeka, iqala ukukhombisa izimpawu zokuxinana, njengokukhuphuka kwe-latency, ukulahleka kwephakethe, njll.

I-WiFi 6 isebenzisa ubuchwepheshe be-8 × 8 Mu Mimo.Lokhu kungaphatha amadivaysi afinyelela ku-8 axhunyiwe futhi asetshenziswe ngokusebenzayo we-LAN engenantambo ngaphandle kokuphazamiseka.Kungcono nokho, i-WiFi 6 Mu Mimo Thuthukisa i-BIDIREctival, okusho ukuthini okuqondile kungaxhuma kwi-router kumabhendi wemvamisa amaningi.Lokhu kusho amandla athuthukisiwe wokulayisha imininingwane kwi-Intanethi, phakathi kokunye ukusetshenziswa.

6. Ama-Frequency band

Umehluko owodwa osobala phakathi kweWiFi 5 ne-WiFi 6 amabhendi wemvamisa walobu buchwepheshe bobabili.I-WiFi 5 isebenzisa kuphela i-5hghtz band futhi inokuphazamiseka okuncane.Okubi ukuthi uhla lwesiginali lufushane futhi amandla okungena ezindongeni nezinye izingqinamba zincishiswa.

I-WiFi 6, ngakolunye uhlangothi, isebenzisa ama-band bandKu-WiFi 6e, abathuthukisi bazokwengeza i-6GHz band emndenini we-WiFi 6.I-WiFi 6 isebenzisa bobabili ama-2.4GHz nama-5GHz band, okusho ukuthi amadivaysi angakwazi ukuskena futhi asebenzise leli bhendi ngokuphazanyiswa okuncane kanye nokusebenza okungcono.Ngale ndlela, abasebenzisi bathola okungcono kakhulu kuwo womabili amanethiwekhi, ngesivinini esisheshayo ebangeni elisondelene nobubanzi obubanzi lapho izinalo zingekho endaweni efanayo.

7. Ukutholakala kombala we-BSS

I-BSS Umbala kungenye into ye-WiFi 6 ebeka ngaphandle kwezizukulwane ezedlule.Lesi yisici esisha se-WiFi 6 ejwayelekile.I-BSS, noma isethi yensizakalo eyisisekelo, yona uqobo isici senethiwekhi ngayinye 802.11.Kodwa-ke, izizukulwane ezingama-WIFI 6 kuphela nezesikhathi esizayo ezizokwazi ukuguqula imibala ye-BSS kwamanye amadivayisi asebenzisa izikhombi zombala we-BSS.Lesi sici sibalulekile ngoba kusiza ukuvikela amasiginali ekugqekezweni.

8. Umehluko wesikhathi sokufakwa

I-Latency isho ukubambezeleka ekudluliseleni amaphakethe kusuka endaweni eyodwa kuya kwenye.Ijubane lokulibaziseka eliphansi eliseduze ne-zero likuhle, okukhombisa ukubambezeleka okuncane noma akukho.Uma kuqhathaniswa ne-WiFi 5, i-WiFi 6 inesikebhe esifushane se-latency, okwenza kube kuhle ngezinhlangano zebhizinisi nezamabhizinisi.Abasebenzisi basekhaya nabo bazosithanda lesi sici kumamodeli wakamuva we-WiFi, njengoba kusho ngokushesha phakathiukuxhumana kwe-terner.
