Informatec Digital » Izinsiza » Umehluko phakathi kwe-Wi-Fi 6E ne-Wi-Fi 7: iyiphi ekufanele

Uma ubulokhu uzwa nge- Wi-Fi 6E kanye ne-Wi-Fi 7 isikhathi esithile manje futhi ungasaqiniseki ukuthi ngayinye inikeza ini, awuwedwa. Eminyakeni embalwa nje, sisuke ekuhluphekeni nge-Wi-Fi ku-router "enikezwe" ngumhlinzeki we-inthanethi ( umhlahlandlela wokubuyekezwa kwe-router kanye ne-access point ) saya ekuphileni ngezindinganiso ezikwazi ukuphatha amashumi ama-gigabits ngomzuzwana, into esanda kuzwakala njengenganekwane yesayensi ekhaya elijwayelekile.

Umbuzo manje awusekho nje ukuthi iyiphi indinganiso esheshayo, kodwa ukuthi iyiphi ewusizo ngempela kuye ngokuxhumeka kwakho kwe-fiber optic , inani lamadivayisi axhunyiwe, ukuthi udlala imidlalo eku-inthanethi, usebenza ekhaya, noma ufuna nje i-Netflix iyeke ukufometha ama-pixel uma wonke umuntu eku-inthanethi ngesikhathi esifanayo. Ake sihlukanise ngokuthula kodwa ngokuqondile umehluko wangempela phakathi kwe-Wi-Fi 6E ne-Wi-Fi 7 , ukuthi kufanele ithuthukiswe nini, nokuthi imane ilahle imali.

Izindinganiso ze-Wi-Fi 6E kanye ne-Wi-Fi 7: 802.11ax vs 802.11be

I-Wi-Fi 6E akuyona indinganiso entsha ngokuphelele , kodwa isandiso se-Wi-Fi 6 ngokusekelwe ku-IEEE 802.11ax specification . Ihlanganyela cishe sonke isisekelo sayo sobuchwepheshe ne-Wi-Fi 6, kodwa inezela ikhono lokusebenza ebhendini le-6 GHz, elivula ibhlogo le-spectrum elihlanzekile nelingenamsindo kakhulu kune-2,4 GHz egcwele noma amabhendi e-5 GHz agcwele.

Ngokuphambene nalokho, i-Wi-Fi 7 yakhelwe phezu kwe-IEEE 802.11be standard , eyaziwa nangokuthi i-EHT (Extremely High Throughput). Lokhu "ukufinyelela okuphezulu kakhulu" akuyona nje ilebula yokumaketha: kuhilela izinguquko ezinkulu endleleni iziteshi ezisetshenziswa ngayo, ukuguqulwa kwesignali, ukuphathwa kwama-band amaningi ngesikhathi esisodwa, kanye nendlela i-hertz ngayinye ye-spectrum etholakalayo esetshenziswa ngayo.

Uma ubheka imininingwane yobuchwepheshe bama-router , omakhalekhukhwini, noma ama-laptop, uzobona ikhodi ethi 802.11ax noma 802.11be kuphela , ngaphandle kokucaciswa kokuthi ngabe yi-Wi-Fi 6, 6E, noma 7. Kubalulekile ukwazi ukuthi i-802.11ax ingaba yi-Wi-Fi 6 noma i-Wi-Fi 6E kuye ngokuthi ifaka ibhendi ye-6 GHz noma cha, kuyilapho i-802.11be ikhomba ngqo amadivayisi e-Wi-Fi 7.

Ngokusho komugqa wesikhathi, i-Wi-Fi 6E yaqala ukufinyelela emakethe ngo-2021 , kuyilapho i-Wi-Fi 7 yethulwa ngokuthengisa ngo-2024 ( ukukhishwa okusha kwe-Wi-Fi 7 router ). Umehluko weminyaka emithathu kumanethiwekhi angenantambo ubalulekile: ngenkathi i-6E isivele isakazeke kakhulu kuma-router aphakathi nendawo kanye nasezingeni eliphezulu, i-Wi-Fi 7 isesezigabeni zokuqala zokusetshenziswa futhi itholakala kakhulu emikhiqizweni ebiza kakhulu.

Amabhendi emvamisa atholakalayo: 2,4, 5 kanye no-6 GHz

Kokubili i-Wi-Fi 6E kanye ne-Wi-Fi 7 zingasebenzisa wonke amabhendi amathathu amakhulu emvamisa: 2,4 GHz, 5 GHz, kanye ne-6 GHz . Ibhendi ye-2,4 GHz inikeza ububanzi obukhulu kodwa isivinini esiphansi futhi ivame ukuminyana namanethiwekhi angomakhelwane namadivayisi amadala. Ibhendi ye-5 GHz ithuthukisa kakhulu isivinini futhi inciphisa ukuphazamiseka, ngezindleko zokunciphisa ukumbozwa lapho kungena ezindongeni.

Ubuchwepheshe obukhulu beminyaka yamuva nje yi- 6 GHz band . Lapha sithola isikhala esiningi kakhulu seziteshi ezibanzi kakhulu, futhi ngaphezu kwakho konke, indawo enamanethiwekhi ambalwa ancintisana ngengxenye efanayo ye-spectrum. Lokhu kuholela ekukhulisweni okukhulu kanye nokuminyana okuncane emafulethini noma ezakhiweni ezinezindawo eziningi zokufinyelela eziseduze.

Kodwa-ke, ukuthi nje i-router yakho ikhangisa i-6 GHz akusho ukuthi konke kuzoshesha. Amadivayisi amaklayenti (amafoni, ama-laptop, ama-TV, njll.) nawo kudingeka ahambisane ne-6 GHz ukuze asebenzise lowo "mzila osheshayo." Ama-smartphone amaningi aphezulu kanye namanye ama-laptop akamuva asevele ayawusekela, kodwa ingxenye enkulu yamadivayisi isasebenza ku-2,4 kanye ne-5 GHz.

Empeleni, amakhaya amaningi asasebenzisa kakhulu i-Wi-Fi engu-2,4 kanye ne-5 GHz , kanye ne-Wi-Fi 6 njengendinganiso evelele (nezindlela zokuthuthukisa ukumbozwa kwakho ). Ibhendi engu-6 GHz kanye nezinzuzo ze-Wi-Fi 6E kanye ne-Wi-Fi 7 ziyabonakala ngempela ezindaweni ezinamadivayisi amaningi axhunyiwe, ukuxhumeka kwefayibha okusheshayo kakhulu, noma amanethiwekhi ezinkampani adinga kakhulu.

Ububanzi kanye nomthamo wesiteshi: 160 MHz vs. 320 MHz

Omunye wemehluko omkhulu phakathi kwe-Wi-Fi 6E ne-Wi-Fi 7 ububanzi besiteshi esiphezulu , okungukuthi, ukuthi "umgwaqo omkhulu" ongakanani ongagcinelwa i-spectrum yokudlulisela okuthile. Uma isiteshi sibanzi, kulapho idatha eningi ingahamba khona ngesikhathi esisodwa.

I-Wi-Fi 6E, ezuzwe njengefa ku-Wi-Fi 6, ingasebenza ngama-bandwidth angu- 20, 40, 80, 80+80, kanye nafinyelela ku-160 MHz . Lokhu sekuvele kubonise intuthuko enkulu phambili uma kuqhathaniswa ne-Wi-Fi 5 ngokwezinga lomthamo kanye nesivinini, ikakhulukazi ku-5 GHz futhi, manje, ku-6 GHz.

I-Wi-Fi 7 ithatha isinyathelo esiqhubekayo, iphakamisa ibha iye kububanzi besiteshi esingu-320 MHz . Ngaphezu kokuvumela iziteshi ezingu-240 MHz ezihambisanayo kanye nokulungiselelwa okungahambisani njenge-160+80 MHz noma i-160+160 MHz, indinganiso yethula izindlela eziguquguqukayo zokuhlanganisa nokwabela izingxenye ze-spectrum kumadivayisi ahlukene , okuthuthukisa ukusebenza kahle okuphelele.

Lokhu kwandiswa kwesiteshi, kuhlanganiswe nokuguqulwa kwesignali okusha, kungenye yezinto ezibalulekile ezichaza ukuthi kungani i-Wi-Fi 7 ingaphinda kane isivinini esiphezulu sethiyori uma kuqhathaniswa ne-Wi-Fi 6E. Kodwa-ke, ukuze kufezwe lezi zivinini, i-router kanye neklayenti kumele basekele lezi ziteshi ezibanzi, futhi indawo yomsakazo kumele ifaneleke—into engavamile ukwenzeka ezimweni zansuku zonke.

Isivinini esiphezulu sethiyori: 9,6 Gbps kuya ku-46 Gbps

Uma kukhulunywa ngezindinganiso ze-Wi-Fi, kukhulunywa njalo ngezibalo zesivinini esiphezulu sethiyori , empeleni eziyimingcele ephezulu efanelekile esingayifinyeleli emhlabeni wangempela. Noma kunjalo, zisebenza ukunikeza umbono wamakhono enguqulo ngayinye.

Endabeni ye-Wi-Fi 6 kanye ne-Wi-Fi 6E, isivinini esiphezulu sethiyori sicishe sibe ngu -9,6 Gbps . Kumsebenzisi wasekhaya, lesi sibalo sesivele sikhulu: ngisho noma kunokuxhumeka kwefayibha engu-1 Gbps, indinganiso yanele futhi ishiya isikhala esanele sokusingatha ithrafikhi yangaphakathi kunethiwekhi yendawo ngaphandle kokuzikhandla.

I-Wi-Fi 7 inyusa lelo jubane eliphezulu libe cishe yi -46 Gbps kuklayenti elilodwa , ngokusho kwezilinganiso ezivela kubakhiqizi abanjengo-Intel no-Qualcomm. Lokhu kungaphezu kwamandla e-Wi-Fi 6E ngokuphindwe kane futhi kufezwa ngokuhlanganiswa kweziteshi ezingu-320 MHz kanye nokuguqulwa okusha kwe-4096-QAM.

Kubalulekile ukugcizelela ukuthi lezi zibalo ziyinkolelo-mbono futhi kunzima ukuzifinyelela ngaphandle kwamalebhu noma ezindaweni ezilawulwa kakhulu. Ukuze ufinyelele ku-46 Gbps, kuzodingeka uhlangabezane nohlu olude lwezimo: ukusakazwa kwendawo okuningi, umthamo omkhulu wesiteshi, amandla esignali amahle kakhulu, ukuphazamiseka okungekho, ihadiwe ephezulu kakhulu kuzo zombili izinhlangothi, njalo njalo.

Empeleni, ngokuxhumeka kwefayibha engu-600 Mbps noma engu-1 Gbps , i-Wi-Fi 6E isivele ihlanganisa i-bandwidth etholakalayo. I-Wi-Fi 7 iqala ukuba nengqondo uma unokuxhumeka okungu-10 Gbps noma ngaphezulu , uma usebenza namaseva okugcina inethiwekhi ashesha kakhulu, noma uma amafayela amakhulu ehanjiswa njalo kunethiwekhi yakho yangaphakathi, njengasezindaweni zamavidiyo zobungcweti, i-VR/AR, noma izikhungo zedatha ezikhethekile kakhulu.

Ukuguqulwa kwesiginali: 1024-QAM vs 4096-QAM

Enye indawo lapho i-Wi-Fi 7 ithuthuka khona kune-Wi-Fi 6E yi- quadrature amplitude modulation (QAM) , inqubo esetshenziswa ukufaka ama-bits olwazi ku-radio wave.

I-Wi-Fi 6E isekelwe ku -1024-QAM ehlanganiswe ne-OFDMA, esevele ivumele ukwenyuka kwamandla nokusebenza kahle uma kuqhathaniswa ne-Wi-Fi 5. Uphawu ngalunye oludlulisiwe lungathwala amabhithi ayi-10 olwazi, olufakwe eziteshini ezifinyelela ku-160 MHz, oluvumela lawo mazinga asondele ku-9,6 Gbps ngaphansi kwezimo ezifanele.

I-Wi-Fi 7 iphakamisa izinga layo libe yi- 4096-QAM , eyaziwa nangokuthi i-4K-QAM. Ngalesi sikimu, uphawu ngalunye lungathwala ama-bits ayi-12 esikhundleni se-10 , okuchaza ukwanda okungokwengqondo okungaba ngu-20% kwisilinganiso sedatha ngaphansi kwazo zonke ezinye izimo. Abakhiqizi abanjengo-Wi-Fi Alliance babika ukuthuthuka okungaba ngu-11-20% kuye ngokucushwa okuthile.

Isibonelo, ngokuhlanganisa i-4096-QAM nesiteshi esingu-56 MHz, isivinini esingaba ngu -575 Mbps singafinyelelwa kuleyo ngxenye ye-spectrum kuphela . Uma sineziteshi ezifika ku-320 MHz, kulula ukubona ukuthi isivinini esiphezulu esishicilelwe sezinga le-802.11be sifinyelelwa kanjani.

Ububi bokwandisa i-modulation order ukuthi iba nzima kakhulu ngekhwalithi yesignali : kudingeka isilinganiso esihle kakhulu sesignali kuya kumsindo, futhi ububanzi obusebenzayo buyancishiswa. Ngakho-ke, i-4096-QAM izophumelela kakhulu emabangeni amafushane nasezindaweni ezingenakuphazamiseka okuningi , kuyilapho ezindaweni eziyinselele uhlelo luzokwehlisa ngokuzenzakalelayo izinga le-modulation ukuze lubeke phambili ukuzinza.

Ikhono le-MU-MIMO kanye namadivayisi amaningi

Kumanethiwekhi asekhaya nasehhovisi, asisaxhumanisi idivayisi eyodwa noma ezimbili kuphela: sikhuluma ngokuxhumana okuningi ngasikhathi sinye, okuhlanganisa omakhalekhukhwini, ama-laptop, amathelevishini, ama-consoles emidlalo, amathebhulethi, nazo zonke izinhlobo zamagajethi e-IoT. Yilapho ubuchwepheshe obufana ne-MIMO ne-MU-MIMO buqala khona ukusebenza.

Umqondo we- MIMO (Multiple Input Multiple Output) usekelwe ekusebenziseni ama-antenna amaningi ukudlulisa nokwamukela idatha, ukwandisa umthamo wesixhumanisi, ububanzi obusebenzayo, kanye nokuthuthukisa isilinganiso sesiginali kuya komsindo. Uma besine-antenna eyodwa ngaphambilini, ukushintshela ku-2x2 noma i-4x4 kusenza sikwazi ukuphindaphinda isivinini ngokusebenzisa imifudlana eminingi yendawo.

Isinyathelo esilandelayo yi -MU-MIMO (Multi-User MIMO) , evumela indawo yokufinyelela ukuthi idlulisele idatha kumadivayisi amaningi ngasikhathi sinye, esikhundleni sokuwasebenzisa ngayinye ngokulandelana okuqinile. Lokhu kubalulekile emakhaya nasemahhovisi anamadivayisi amaningi axhunyiwe ngoba kunciphisa imigqa yangaphakathi ye-router futhi kusebenzisa kangcono isikhathi somoya esitholakalayo.

Nge-Wi-Fi 6E, sesivele sijabulela ukucushwa okufika ku-8x8 UL/DL MU-MIMO , okusho ukuthi indawo yokufinyelela ingaphatha ukulayishwa okungu-8 kanye nokulandwa okungu-8 ngesikhathi esisodwa. Lokhu kuyindawo enamandla kakhulu ezindaweni zokuhlala, lapho ingavamile ukusunduzwa khona.

I-Wi-Fi 7 inyusa lesi sibalo sibe yi- 16x16 UL/DL MU-MIMO , iphinda kabili inani elingaba khona lemifudlana efanayo. Lokhu kuhambisana kahle nesimo lapho indinganiso yaklanywa khona: amanethiwekhi aminyene kakhulu anenani elikhulu lamakhasimende asebenzayo ngesikhathi esisodwa , njengamahhovisi amakhulu, izikhala zomphakathi, izinkundla zemidlalo, noma amakhaya asebenza ngokuzenzakalelayo.

Ukusebenza Kwezixhumanisi Eziningi (i-MLO): ukusebenzisa amabhendi amaningi ngasikhathi sinye

Esinye sezici eziphawuleka kakhulu ze-Wi-Fi 7 yi -Multi-Link Operation (MLO) , umsebenzi wezinga le-MAC oshintsha indlela idivayisi exhuma ngayo endaweni yokufinyelela. Kuze kube manje, noma ngabe i-router ingasakaza kuma-band amaningi (2,4, 5, kanye ne-6 GHz), iklayenti lizoxhuma kuphela ku-band eyodwa ngesikhathi.

Nge-MLO, idivayisi ye-Wi-Fi 7 ingasebenzisa izixhumanisi eziningi kuma-band ahlukene ngasikhathi sinye , ihlanganise umthamo wazo noma ishintshe phakathi kwazo ngokuguquguqukayo kuye ngekhwalithi yesiginali kanye nokuminyana. Kunjengokungathi, esikhundleni sokukhetha umgwaqo omkhulu owodwa, ifoni yakho ingahamba emigwaqweni emibili noma ngaphezulu ngesikhathi esisodwa, isabalalise ithrafikhi njengoba kudingeka.

Empeleni, i-MLO ivumela ukusebenza okuthuthukisiwe, ukubambezeleka okuncishisiwe, kanye nokwethenjelwa okwandisiwe ngoba uhlelo lungaphambukisa ithrafikhi kusuka ebhendini eliminyene liye kwelingaminyene kangako ngaphandle kokuthi umsebenzisi aqaphele noma yikuphi ukuphazamiseka. Abakhiqizi abanjengoBroadcom no-Aruba baqokomisa ukuthi, ngokuhlanganisa i-MLO neziteshi ezingu-320 MHz, umthamo wenethiwekhi omkhulu ngokuphindwe kahlanu kanye nokubambezeleka okuphansi ngokuphindwe kane uma kuqhathaniswa ne-Wi-Fi 6E kungafinyelelwa ezimweni ezigcwele kakhulu.

Izinhlelo zenethiwekhi ye-Mesh (i-Wi-Fi Mesh) zizozuza kakhulu kwi-MLO: ukuxhumana phakathi kwe-router eyinhloko nama-node e-satellite kuzokwazi ukusebenzisa ama-band amaningi ngesikhathi esisodwa, kuthuthukiswe i-backhaul futhi kugwenywe izithiyo, ikakhulukazi lapho i-backhaul enezintambo ingatholakali.

Kodwa-ke, kubalulekile ukukhumbula ukuthi i-MLO isebenza kuphela uma zombili iziphetho ziyi-Wi-Fi 7. Uma uhlangothi olulodwa luyi-Wi-Fi 6E noma ngaphambili, uxhumano luzosebenza njengobudlelwano bendabuko bebhendi eyodwa, ngaphandle kwamandla okuhlanganisa izixhumanisi.

Ukusebenza kahle kwe-Spectral, i-RU kanye nokuphathwa kokuphazamiseka

I-Wi-Fi 6 yethule ushintsho olubalulekile nge -OFDMA (Orthogonal Frequency Division Multiple Access) , evumela isiteshi ukuthi sihlukaniswe sibe amayunithi amancane ezinsizakusebenza (ama-RU) futhi sinikezwe amadivayisi ahlukene ngokwezidingo zawo. Lokhu kuvimbela iklayenti elilodwa ukuthi lilawule isiteshi sonke ukuze sithumele idatha encane kuphela futhi kuthuthukisa ukusebenza kahle okuphelele lapho amadivayisi amaningi esebenza.

I-Wi-Fi 6E igcina lolu hlelo lokwabiwa kwe-RU kudivayisi ngayinye , obekuvele kuyintuthuko enkulu kune-Wi-Fi 5, ikakhulukazi ezindaweni ezinabasebenzisi abaningi abancane (i-IoT, iselula, njll.). Kodwa-ke, ukwabiwa kwahlala kuqinile futhi kwanikeza amathuba ambalwa okuhlanganisa.

I-Wi-Fi 7 ithuthukisa lo mbono ngokuvumela ama-RU amaningi ukuthi anikezwe kudivayisi eyodwa , okunikeza indawo yokufinyelela ukuguquguquka okukhulu ekwabeni i-spectrum ngokwezidingo zeklayenti ngalinye. Ngaphezu kwalokho, kufakiwe ukuthuthukiswa okufana ne- 512 compressed block-back , okunciphisa izindleko zokwamukelwa futhi kuthuthukisa ukusetshenziswa komoya.

Esinye isici esisha esibalulekile ukusetshenziswa kwesiteshi okuguquguqukayo ngokusebenzisa "ukubhoboza ." Ezinguqulweni zangaphambilini, uma ingxenye yesiteshi esibanzi iphazamiseke (isibonelo, kusuka kunethiwekhi eseduze), ingafaka engcupheni isiteshi sonke. Nge-Wi-Fi 7, ingxenye eyinkinga kuphela "ebhobozwa," kanti ingxenye esele yesiteshi ingasetshenziswa ngaphandle kokulahlekelwa okukhulu kokusebenza.

Uma sibuyela esifanisweni somgwaqo omkhulu, kunjengokungathi imbobo emzileni owodwa ayisaphoqi ukuthi wonke umzila uvalwe, kodwa indawo eyonakele kuphela ephawuliwe futhi izimoto zingaqhubeka nokuhamba kusetshenziswa yonke i-asphalt etholakalayo.

Ukubambezeleka, ukuzinza, kanye nokuhlangenwe nakho okujulile

Ngale kwesivinini esingakaphethwa, abantu abaningi baqaphela umehluko kakhulu lapho ukubambezeleka kuncipha futhi ukuguquguquka kwempendulo kuncipha . Ngamanye amazwi, lapho izingcingo zevidiyo zingenazo izikhawu ezincane, imidlalo eku-inthanethi isebenza kahle, futhi ikhwalithi yokusakaza ividiyo ayiguquguquki njalo.

I-Wi-Fi 6 kanye ne-6E sezivele zithathe isinyathelo esikhulu kulokhu ngenxa ye -OFDMA, i-MU-MIMO ethuthukisiwe, kanye nokulawula okungcono kokushayisana . Isilinganiso sokubambezeleka sehle kakhulu uma kuqhathaniswa ne-Wi-Fi 5, ikakhulukazi lapho amadivayisi amaningi abelana ngenethiwekhi.

I-Wi-Fi 7 yakhelwe ngqo ukuhlangabezana nesidingo esikhulayo sokuhlangenwe nakho okusebenzisanayo nokujulile : i-virtual ne-augmented reality, i-extended reality, ukuqeqeshwa kwe-3D, ukusakaza ividiyo ye-4K ne-8K, imidlalo yamafu, kanye nezinhlelo zokusebenza ze-telepresence ezithuthukisiwe. Kuzo zonke lezi zinhlelo zokusebenza, i-bandwidth ephezulu yodwa ayanele; inethiwekhi ebikezelwayo ene-latency ephansi kakhulu futhi ezinzile ibalulekile.

Ngokuhlanganisa i-MLO, iziteshi ezibanzi, i-4K-QAM, kanye nokuphathwa kwe-RU okuguquguqukayo, i-Wi-Fi 7 ingaletha amanethiwekhi azinzile ngisho nangaphansi kwethrafikhi enkulu . Kubasebenzisi basekhaya abafuna izinto eziningi, lokhu kuholela ekudlaleni imidlalo eku-inthanethi okunezikhawu ezimbalwa zokulibaziseka, izingcingo zevidiyo ezibushelelezi, kanye nokusakaza okunesinqumo esiphezulu okungenazithiyo, uma nje yonke ingqalasizinda (umqhubi, iseva ekude, njll.) ifinyelela ezingeni elifanele.

Ububanzi besignali kanye namanethiwekhi e-mesh emakhaya ayinkimbinkimbi

Ngokuphathelene nobubanzi obuphathekayo besiginali , i-Wi-Fi 6E kanye ne-Wi-Fi 7 azishintshi imithetho yefiziksi. Ibhendi ye-2,4 GHz isangena kangcono ezindongeni naseziphahleni, ngezindleko zesivinini kanye nokwabelana nge-spectrum namanye amadivayisi amaningi. Amabhendi e-5 kanye ne-6 GHz anikeza amandla amakhulu kodwa ancipha kakhulu uma edlula ezindongeni zezitini noma zekhonkrithi.

Uma uhlala efulethini elinezindonga ezijiyile kakhulu noma isakhiwo sikakhonkolo , kunzima ukumboza yonke indlu nge-router eyodwa nje, kungakhathaliseki ukuthi ingeyesimanje kangakanani. Kulezi zimo, ikhambi elingokoqobo lihlala liwukukhetha amanethiwekhi e-mesh noma izindawo zokufinyelela ezengeziwe (noma usethe i-Wi-Fi repeater ), okungcono kakhulu ukuthi ixhunywe ngekhebula le-Ethernet ukuze ibuyisele emuva noma nini lapho kungenzeka.

Izinhlelo ze-Wi-Fi 6E mesh sezivele zivumela ibhendi ye-6 GHz ukuthi isetshenziswe "njengomzila ozinikele" phakathi kwama-node, okunciphisa ukuphazamiseka kwamadivayisi abasebenzisi. Nge-Wi-Fi 7, lo mbono uthuthukiswa nge-MLO kanye nomthamo omkhulu jikelele, okwenza kube lula izixhumanisi zangaphakathi eziqinile nezisheshayo ngisho nalapho ithrafikhi ikhula.

Kunoma ikuphi, iphuzu elibalulekile kumsebenzisi ukuthi i-router ebuyekeziwe futhi elungiselelwe kahle ene-WPA3 , okwamanje, iyindlela ephephile kakhulu kokubili i-Wi-Fi 6E kanye ne-Wi-Fi 7. Into ebalulekile kuzoba ukugcina i-firmware isesikhathini futhi usebenzise amaphasiwedi aqinile, kungakhathaliseki ukuthi iyiphi indinganiso ethile.

Ukuhambisana kwedivayisi kanye nokuvuthwa kohlelo lwe-ecosystem

Enye yezinkinga eziphindaphindayo ngendinganiso ngayinye entsha ukuthi inethiwekhi ingeyesimanje kuphela njengesixhumanisi sayo esibuthakathaka . Akusizi kakhulu ukuba ne-router yesimanje uma iningi lamadivayisi akho lingakhulumi ulimi olufanayo.

Njengamanje, i-Wi-Fi 6 (kanye nohlobo lwayo lwe-6E) isibe yindinganiso esakazeke kakhulu kumafoni aphathekayo asezingeni eliphakathi kanye nasezingeni eliphezulu, ama-laptop akamuva, kanye nama-router anikezwa yizinkampani eziningi zenethiwekhi. Amanye amamodeli e-smartphone aphezulu asevele esekela i-6 GHz, kanti amanye, njengezizukulwane ezithile zama-iPhone, asasekela i-Wi-Fi 6 kuphela ku-2,4 kanye ne-5 GHz.

I-Wi-Fi 7 isanda kufika futhi okwamanje ikhawulelwe emishinini ebiza kakhulu nesezingeni eliphezulu : ama-router aphezulu avela kubakhiqizi abanjengo-TP-Link, i-NETGEAR, kanye nemikhiqizo efanayo, ama-laptop okuqala anama-chipset ahambisanayo, kanye namakhadi athile enethiwekhi azinikele. Lokhu kuyaqondakala: njengoba kunjalo nge-Wi-Fi 6E, kuzothatha iminyaka embalwa ukuthi abakhiqizi bahlanganise kabanzi indinganiso entsha emigqeni yabo yemikhiqizo.

Lokhu kusho ukuthi, eminyakeni ezayo, sizophila ngenhlanganisela yamadivayisi e-Wi-Fi 5, Wi-Fi 6, Wi-Fi 6E, kanye ne-Wi-Fi 7. Izindaba ezinhle ukuthi amazinga agcina ukuhambisana okungemuva: i-router ye-Wi-Fi 7 izokwazi ukuxhumana nemishini emidala, yize, ngokwemvelo, la madivayisi azokwazi ukusizakala kuphela ngamakhono enqubo yawo.

Uma ucabanga ngokuthuthukisa ingqalasizinda yakho, kufanelekile ukucabangela ukuthi ukuphi emjikelezweni wakho wokuthuthukisa idivayisi . Uma ungahleli ukushintsha ifoni yakho, i-laptop, noma i-smart TV maduze nje, kungase kungabi nangqondo ukushintshela ku-Wi-Fi 7 okwamanje.

Intengo, imakethe, nokuthi kufanele nini ukuthuthukiswa

Esinye isici esithonya kakhulu isinqumo yintengo yemishini . Ama-router kanye nezinhlelo ze-Mesh ezine-Wi-Fi 6 noma i-6E sezithengeka kakhulu, futhi kulezi zinsuku kulula kakhulu ukuthola amamodeli anesilinganiso esihle kakhulu sentengo nokusebenza.

Ngokuphambene nalokho, ama-router nama-kit okuqala e-Wi-Fi 7 Mesh eza namanani aphezulu , aqinisekiswa ubusha bezinga, ubunzima bezingxenye zalo kanye neqiniso lokuthi, okwamanje, ahloselwe abasebenzisi abathuthukile, izinkampani kanye nabathandi abafuna okwakamuva ngisho noma bengeke bakusebenzise ngokugcwele kusukela ngosuku lokuqala.

Uma, isibonelo, unoxhumano lwe-fiber optic lwe-1 Gbps kanye nokwakheka kwekhaya okuyinkimbinkimbi , uhlelo lwe-Wi-Fi 6E Mesh luvame ukwanele ukuthola ukumbozwa okuhle nokusebenzisa kahle uxhumano lwakho. Kulowo mongo, ukukhokha iprimiyamu enkulu ye-Wi-Fi 7 kungase kungahumushi ukuthuthuka okubonakalayo ekusebenziseni kwakho kwansuku zonke, ngaphandle kokuthi uhlela ukwenza isivumelwano se-bandwidth eyengeziwe noma ukusebenzisa izinsizakalo zasendaweni ezidinga kakhulu.

Kumabhizinisi anesabelomali esincane se-IT , inethiwekhi eklanywe kahle esebenzisa i-Wi-Fi 6 noma i-6E ingahlala iyisisombululo esihle iminyaka eminingi. Uma umjikelezo wakho wokuthuthukisa useminyakeni engu-2-3, kungaba ngcono ukulinda i-Wi-Fi 7 ukuthi ikhule , amanani ehle, kanye namadivayisi amaningi amakhasimende ukuze ayisebenzise.

Ngakolunye uhlangothi, uma ukhetha ukuba phambili kwezobuchwepheshe , ngaphandle kwemikhawulo eminingi yesabelomali, ungakhetha ukugxumela ku-Wi-Fi 6E ngezikhathi ezithile uye ku-Wi-Fi 7 uma isikhathi sifika, noma uye ngqo ku-router ye-Wi-Fi 7 ukuze ulungiselele inethiwekhi yakho yasekhaya amadivayisi ahambisanayo esikhathini esizayo.

I-Wi-Fi 6E vs Wi-Fi 7: Ukubuka Konke kanye Nezimo Zokusetshenziswa

Uma umgomo wakho kuyinethiwekhi yasekhaya ezinzile enokusibekela okuhle okungaphatha kalula izingcingo eziningi zevidiyo, ukusakaza kwe-4K, kanye nokudlala imidlalo ethile ku-inthanethi, i-Wi-Fi 6E ngokuvamile iyindlela elinganiselayo kakhulu etholakalayo namuhla. Isebenzisa ibhendi engu-6 GHz uma kutholakala amadivayisi ahambisanayo, inikeza isivinini esingaphezu kwesanele, futhi isivele inesistimu evuthiwe.

Okwamanje, i-Wi-Fi 7 ihloselwe izimo ezidinga kakhulu : imicu ye-multi-gigabit, amahhovisi anabasebenzisi abaningi ngesikhathi esisodwa, amanethiwekhi anethrafikhi yangaphakathi enamandla kakhulu, izinhlelo zokusebenza ze-virtual noma ze-augmented reality, ukusakaza kwe-8K, imidlalo yokuncintisana, noma izindawo zokusebenza ezinamafayela amakhulu evidiyo namamodeli e-3D.

Ekhaya elijwayelekile eline-fiber engu-1 Gbps kanye nenani elifanele lamadivayisi, abasebenzisi abaningi bazobona izinzuzo zokuhlela inethiwekhi okuhle (indawo ye-router, ukusetshenziswa kwe-mesh, ukuxhuma izintambo lapho kungenzeka khona) ngaphezu kokugxuma kusuka ku-6E kuya ku-7. Inkinga ivame ukuba sekuxhumaneni kwe-inthanethi, amaseva akude, noma ukwakheka kwendlu uqobo.

Ngakho-ke, ngaphambi kokunquma ngendinganiso ethile noma enye, kufanelekile ukuzibuza umbuzo olula kakhulu: "Yini engiyidingayo ngempela kunethiwekhi yami, futhi iyini inhloso yenhlangano yami noma ikhaya lami?" Ukusuka lapho, ungahlola ukuthi useqenjini elihlala lifuna ubuchwepheshe bamuva, noma ngabe bungasetshenziswa ngokugcwele, noma ngabe ukhetha ubuchwepheshe obuqinisekisiwe, obuzinzile obunesilinganiso esingcono sezindleko nezinzuzo.

Uma sibheka wonke umehluko wezobuchwepheshe—okujwayelekile, amabhendi, ububanzi besiteshi, ukuguqulwa kwezwi, i-MU-MIMO, i-MLO, ukubambezeleka, ukuphepha, ukuhambisana, kanye nentengo—kusobala ukuthi i-Wi-Fi 7 ingcono kakhulu kune-Wi-Fi 6E ephepheni, kodwa futhi empilweni yansuku zonke yabasebenzisi abaningi, i-Wi-Fi 6E izoqhubeka nokuba wusizo isikhathi eside futhi, uma isetshenziswa kahle, yanele izidingo zamanje zokuphequlula, ukusakaza, ukusebenza ngocingo, kanye nokuzijabulisa kwedijithali.
