Ezimpilweni zansuku zonke, wonke umuntu ujwayelene negama elithi WiFi, futhi singase sibhekane nesimo esilandelayo: Uma abantu abaningi bexhunywe ku-Wi-Fi efanayo ngesikhathi esisodwa, abanye abantu bayaxoxa bebuka amavidiyo, futhi inethiwekhi iba bushelelezi kakhulu. , okwamanje, ufuna ukuvula ikhasi lewebhu, kodwa kuthatha isikhathi eside ukulayisha.
Lokhu kuwukushiyeka kobuchwepheshe bamanje bokudlulisa i-WiFi. Ngokombono wezobuchwepheshe, owedlule Imodyuli ye-WiFi Ubuchwepheshe bokudlulisa obusetshenzisiwe bekuyi-SU-MIMO, obungabangela izinga lokudlulisela ledivayisi ngayinye exhunywe kwi-WiFi ukuthi lihluke kakhulu. Ubuchwepheshe bokudlulisa be-WiFi 6 yi-OFDMA+8x8 MU-MIMO. Amarutha asebenzisa i-WiFi 6 ngeke abe nale nkinga, futhi ukubuka amavidiyo abanye ngeke kuphazamise ukulanda noma ukuphequlula kwakho iwebhu. Lesi futhi ngesinye sezizathu zokuthi kungani i-WiFi iqhathaniswa nobuchwepheshe be-5G futhi ithuthuka ngokushesha.
Yini i-WiFi 6?
I-WiFi 6 ibhekisela esizukulwaneni sesithupha sobuchwepheshe benethiwekhi engenantambo. Esikhathini esidlule, sasisebenzisa i-WiFi 6, futhi akunzima ukuyiqonda. Phambilini bekukhona i-WiFi 5/1/2/3, futhi ubuchwepheshe babunganqamuki. Ukubuyekezwa kwe-WiFi 4 kusebenzisa ubuchwepheshe obubizwa nge-MU-MIMO, obuvumela irutha ukuthi ixhumane namadivayisi amaningi ngesikhathi esisodwa esikhundleni sokulandelana. I-MU-MIMO ivumela irutha ukuthi ixhumane namadivayisi amane ngesikhathi, futhi i-WiFi 6 izovumela ukuxhumana namadivayisi angafinyelela kwangu-6. I-WiFi 8 iphinde isebenzisa obunye ubuchwepheshe, obufana ne-OFDMA futhi budlulise ukwakheka kwe-beamform, kokubili okuthuthukisa ukusebenza kahle namandla enethiwekhi ngokulandelana. Isivinini se-WiFi 6 ngu-6 Gbps. Ubuchwepheshe obusha ku-WiFi 9.6 buvumela idivayisi ukuthi ihlele ukuxhumana nerutha, inciphise isikhathi esidingekayo ukuze igcine i-antenna ivuliwe ukuze idlulise futhi iseshe amasignali, okusho ukunciphisa ukusetshenziswa kwamandla ebhethri nokuthuthukisa impilo yebhethri.
Ukuze amadivayisi we-WiFi 6 agunyazwe yi-WiFi Alliance, kufanele asebenzise i-WPA3, ngakho-ke uma uhlelo lokunikeza izitifiketi seluqalisiwe, amadivayisi amaningi e-WiFi 6 azoba nokuvikeleka okuqinile. Ngokuvamile, i-WiFi 6 inezici ezintathu ezinkulu, okungukuthi, isivinini esisheshayo, ephephile, nokonga amandla okwengeziwe.
Ishesha kangakanani i-WiFi 6 kunangaphambili?
I-WiFi 6 izikhathi ezingama-872 kune-WiFi 1.
Izinga le-WiFi 6 liphezulu kakhulu, ikakhulukazi ngoba kusetshenziswa i-OFDMA entsha. Irutha engenantambo ingaxhunywa kumadivayisi amaningi ngesikhathi esisodwa, ixazulule ngempumelelo ukuminyana kwedatha nokubambezeleka. Njenge-WiFi yangaphambilini bekuwumzila owodwa, imoto eyodwa kuphela engadlula ngesikhathi, nezinye izimoto zidinga ukulinda emgqeni futhi zihambe ngayinye ngayinye, kodwa i-OFDMA ifana nemizila eminingi, futhi izimoto eziningi zihamba ngesikhathi esisodwa ngaphandle ulayini.
Kungani ukuphepha kwe-WiFi 6 kuzokwanda?
Isizathu esiyinhloko ukuthi i-WiFi 6 isebenzisa isizukulwane esisha sephrothokholi yokubethela ye-WPA3, futhi amadivayisi asebenzisa isizukulwane esisha sephrothokholi yokubethela ye-WPA3 angaphasisa isitifiketi se-WiFi Alliance. Lokhu kungavimbela ukuhlasela kwe-brute force futhi kukwenze kuphephe futhi kuvikeleke kakhulu.
Kungani i-WiFi 6 igcina amandla engeziwe?
I-Wi-Fi 6 isebenzisa ubuchwepheshe be-Target Wake Time. Lobu buchwepheshe bungaxhumeka kumzila ongenantambo kuphela uma buthola imiyalelo yokudlulisela, futhi buhlala busesimweni sokulala ngezinye izikhathi. Ngemuva kokuhlola, ukusetshenziswa kwamandla kwehliswa cishe ngo-30% uma kuqhathaniswa nangaphambili, okunweba kakhulu impilo yebhethri, ehambisana kakhulu nemakethe yasekhaya ehlakaniphile yamanje.
Yiziphi izimboni ezinezinguquko ezinkulu ezibangelwa i-WiFi 6?
Indawo Yehhovisi Lasekhaya/Ibhizinisi
Kulo mkhakha, i-WiFi idinga ukuncintisana nobuchwepheshe benethiwekhi yeselula obuvamile nobunye ubuchwepheshe obungenawaya obufana ne-LoRa. Kungabonakala ukuthi, ngokusekelwe ku-broadband yeselula enhle kakhulu yasekhaya, i-WiFi 6 inezinzuzo ezisobala ekudumeni nasekuqhudelaneni ezimeni zasekhaya. Okwamanje, kungakhathaliseki ukuthi imishini yehhovisi yebhizinisi noma okokuzijabulisa kwasekhaya, kuvame ukuthuthukiswa ngokudluliswa kwe-5G CPE ukuze kutholwe isignali ye-WiFi. Isizukulwane esisha se-WiFi 6 sinciphisa ukuphazamiseka kwemvamisa futhi sithuthukisa ukusebenza kahle kwenethiwekhi namandla, siqinisekisa amasignali e-5G kubasebenzisi abaningi ngesikhathi esisodwa, nokuqinisekisa ukuzinza kwenethiwekhi lapho ukuguqulwa kwanda.
Izimo zesidingo somkhawulokudonsa ophezulu njenge-VR/AR
Eminyakeni yakamuva, i-VR/AR, 4K/8K nezinye izinhlelo zokusebenza zinezidingo eziphezulu zomkhawulokudonsa. I-bandwidth yangaphambili idinga ngaphezu kwe-100Mbps, futhi umkhawulokudonsa wakamuva udinga okungaphezu kuka-50Mbps. Uma ucabangela umthelela wendawo yangempela yenethiwekhi ku-WiFi 6, Engase ilingane namakhulu e-Mbps kuya ku-1Gbps noma ngaphezulu ku-5G yokuhlola kwangempela kwezohwebo, futhi ingahlangabezana ngokugcwele nezimo zohlelo lokusebenza lomkhawulokudonsa ophezulu.
3. Indawo yokukhiqiza izimboni
Umkhawulokudonsa omkhulu nokubambezeleka okuphansi kwe-WiFi 6 kunweba izimo zohlelo lokusebenza lwe-WiFi kusukela kunethiwekhi yamahhovisi ezinkampani kuya ezimweni zokukhiqiza ezimbonini, njengokuqinisekisa ukuzulazula okungenazihibe kwama-AGV asefekthri, ukusekela ukuthwebula ividiyo ngesikhathi sangempela samakhamera ezimboni, njll. I-plug-in yangaphandle. indlela isekela ukuxhumana okwengeziwe kwephrothokholi ye-IoT, ibona ukuhlanganiswa kwe-IoT ne-WiFi, futhi yonga izindleko.
Ikusasa le-WiFi 6
Isidingo semakethe esizayo nesikali somsebenzisi we-WiFi 6 sizoba sikhulu kakhulu. Eminyakeni emibili edlule, isidingo sama-chips e-Wi-Fi ku-inthanethi Yezinto njengezindlu ezihlakaniphile namadolobha ahlakaniphile sikhulile, futhi ukuthunyelwa kwe-chip ye-WiFi kuye kwaphindeka futhi. Ngokungeziwe kumatheminali kagesi omthengi wendabuko kanye nezinhlelo zokusebenza ze-IoT, ubuchwepheshe be-WiFi buphinde busebenze kakhulu ezimeni ezintsha zohlelo lokusebenza ezinesivinini esikhulu njenge-VR/AR, ividiyo enencazelo ephezulu kakhulu, ukukhiqizwa kwezimboni kanye nokukhiqiza, nama-chips e-WiFi alezi zinhlelo zokusebenza kulindeleke. ukuqhubeka nokukhula eminyakeni emihlanu ezayo, futhi kulinganiselwa ukuthi yonke imakethe ye-WiFi chip yaseChina izofinyelela kuma-yuan ayizigidi eziyizinkulungwane ezingama-27 ngo-2023.
Njengoba kushiwo ngaphambili, izimo zohlelo lokusebenza lwe-WiFi 6 ziba ngcono. Imakethe ye-WiFi 6 kulindeleke ukuthi ifinyelele kuma-yuan ayizigidi eziyizinkulungwane ezingu-24 ngo-2023. Lokhu kusho ukuthi ama-chips asekela i-akhawunti evamile ye-WiFi 6 cishe cishe u-90% wawo wonke ama-chip we-WiFi.
Inhlanganisela yegolide yozakwethu "ye-5G eyinhloko yangaphandle, i-WiFi 6 main internal" edalwe ama-opharetha izothuthukisa kakhulu ulwazi lwabasebenzisi abaku-inthanethi. Ukusetshenziswa okusakazekile kwenkathi ye-5G ngesikhathi esisodwa kukhuthaza ukusabalala okugcwele kwe-WiFi 6. Ngakolunye uhlangothi, i-WiFi 6 iyisisombululo esingabizi kakhulu esingenza ukukhubazeka kwe-5G; ngakolunye uhlangothi, i-WiFi 6 inikeza ulwazi olufana ne-5G kanye nokusebenza. Ubuchwepheshe obungenawaya endlini buzogqugquzela ukuthuthukiswa kwezinhlelo zokusebenza emadolobheni ahlakaniphile, i-inthanethi Yezinto, kanye ne-VR/AR. Ekugcineni, kuzothuthukiswa imikhiqizo eminingi ye-WiFi 6.
I-WiFi 6 Amamojula ahlobene
