Uyafuna ukwazi ukuthi isoka lakho liyathanda ukudlala imidlalo yekhompyutha? Ake ngibelane nawe ithiphu, ungabheka ikhompuyutha yakhe ukuthi ixhunywe ikhebula lenethiwekhi noma cha. Ngoba abafana banezidingo eziphezulu ngesivinini senethiwekhi nokubambezeleka lapho bedlala imidlalo, futhi iningi le-WiFi yasekhaya yamanje ayikwazi ukwenza lokhu ngisho noma isivinini senethiwekhi ye-broadband sishesha ngokwanele, ngakho abafana abavame ukudlala imidlalo bavame ukukhetha ukufinyelela kwezintambo ku-broadband qinisekisa indawo yenethiwekhi ezinzile futhi esheshayo.
Lokhu futhi kubonisa izinkinga zokuxhuma kwe-WiFi: ukubambezeleka okuphezulu nokungazinzi, okusobala kakhulu esimweni sabasebenzisi abaningi ngesikhathi esisodwa, kodwa lesi simo sizothuthukiswa kakhulu ngokufika kwe-WiFi 6. Lokhu kungenxa yokuthi i-WiFi 5, okuyinto isetshenziswa abantu abaningi, isebenzisa ubuchwepheshe be-OFDM, kuyilapho i-WiFi 6 isebenzisa ubuchwepheshe be-OFDMA. Umehluko phakathi kwalezi zindlela ezimbili ungaboniswa ngezithombe:
Emgwaqweni ONGAthwala imoto eyodwa kuphela, i-OFDMA ingadlulisa ngesikhathi esisodwa amatheminali amaningi ngokuhambisana, isuse olayini nokuminyana, ITHUTHUKISE UKUSEBENZA KANYE NOkunciphisa ukubambezeleka. I-OFDMA ihlukanisa isiteshi esingenantambo sibe iziteshi ezingaphansi eziningi kusizinda samafrikhwensi, ukuze abasebenzisi abaningi bakwazi ukudlulisa idatha ngesikhathi esisodwa ngokufana esikhathini ngasinye, okuthuthukisa ukusebenza kahle nokunciphisa ukubambezeleka komugqa.
I-WIFI 6 ibilokhu iphambili kusukela yethulwa, njengoba abantu befuna ukwanda kwamanethiwekhi asekhaya angenazintambo. Ngaphezulu kwezigidigidi ezi-2 zamatheminali e-Wi-Fi 6 athunyelwe ekupheleni kuka-2021, okubalelwa ngaphezu kuka-50% wakho konke ukuthunyelwa kwe-Wi-Fi, futhi lelo nani lizokhula lifinyelele ezigidini eziyizinkulungwane ezingu-5.2 ngo-2025, ngokusho kwenkampani ehlaziya i-IDC.
Nakuba i-Wi-Fi 6 igxile ekuhlangenwe nakho komsebenzisi ezimeni zokuminyana okuphezulu, izinhlelo zokusebenza ezintsha ziye zavela eminyakeni yamuva nje ezidinga ukudlula okuphezulu nokubambezeleka, njengamavidiyo e-ultra-high-definition afana namavidiyo angu-4K kanye ne-8K, ukusebenza kude, ividiyo eku-inthanethi. inkomfa, nemidlalo ye-VR/AR. Ama-Tech giants nawo abona lezi zinkinga, futhi i-Wi-Fi 7, enikeza isivinini esidlulele, umthamo ophezulu kanye ne-latency ephansi, igibela igagasi. Ake sithathe i-Wi-Fi 7 ye-Qualcomm njengesibonelo futhi sikhulume ngalokho i-Wi-Fi 7 ethuthukisiwe.
I-Wi-fi 7: Konke Ngekubambezeleka Okuphansi
1. Umkhawulokudonsa Ophakeme
Futhi, thatha imigwaqo. I-Wi-fi 6 isekela ngokuyinhloko amabhendi e-2.4ghz ne-5ghz, kodwa umgwaqo ongu-2.4ghz wabelwe i-Wi-Fi yakuqala nobunye ubuchwepheshe obungenawaya obufana ne-Bluetooth, ngakho uba nesiminyaminya kakhulu. Imigwaqo eku-5GHz ibanzi futhi ayiminyene kakhulu kunaku-2.4ghz, okuhumushela kuzivinini ezisheshayo nomthamo owengeziwe. I-Wi-fi 7 isekela ngisho nebhendi engu-6GHz phezu kwalawa mabhendi amabili, inweba ububanzi besiteshi esisodwa ukusuka ku-Wi-Fi 6′s 160MHz kuya ku-320MHz (engathwala izinto eziningi ngesikhathi). Ngaleso sikhathi, i-Wi-Fi 7 izoba nenani eliphakeme lokudlulisela elingaphezu kuka-40Gbps, eliphindwe kane kune-Wi-Fi 6E.
2. Ukufinyelela kwezixhumanisi eziningi
Ngaphambi kwe-Wi-Fi 7, abasebenzisi bebengasebenzisa kuphela umgwaqo owodwa ozifanele kangcono izidingo zabo, kodwa isisombululo se-Qualcomm's Wi-Fi 7 siphusha imikhawulo ye-Wi-Fi nakakhulu: ngokuzayo, womathathu amabhendi azokwazi ukusebenza ngesikhathi esisodwa, ukunciphisa ukuminyana. Ukwengeza, ngokusekelwe emsebenzini we-multi-link, abasebenzisi bangaxhuma ngokusebenzisa iziteshi eziningi, basebenzise lokhu ukuze bagweme ukuminyana. Isibonelo, uma kukhona ithrafikhi kwelinye lamashaneli, idivayisi ingasebenzisa esinye isiteshi, okuholela ekubambezelekeni okuphansi. Ngaleso sikhathi, kuye ngokutholakala kwezifunda ezihlukene, izixhumanisi eziningi zingasebenzisa iziteshi ezimbili kubhendi ye-5GHz noma inhlanganisela yamashaneli amabili kumabhendi we-5GHz kanye ne-6GHz.
3. Hlanganisa Isiteshi
Njengoba kushiwo ngenhla, umkhawulokudonsa we-Wi-Fi 7 unyusiwe waba ngu-320MHz (ububanzi bemoto). Kubhendi ye-5GHz, alikho ibhendi ye-320MHz eqhubekayo, ngakho-ke yisifunda esingu-6GHz kuphela esingasekela le modi eqhubekayo. Ngokusebenza komkhawulokudonsa ophezulu ngasikhathi sinye we-multi-link, amabhendi amabili okuvama angahlanganiswa ngesikhathi esisodwa ukuze kuqoqwe ukuphuma kweziteshi ezimbili, okungukuthi, amasiginali amabili we-160MHz angahlanganiswa akhe isiteshi esisebenzayo esingu-320MHz (ububanzi obandisiwe). Ngale ndlela, izwe elifana nelethu, elingakawabi ama-spectrum angu-6GHz, linganikeza neshaneli ephumelelayo ebanzi ngokwanele ukuze kuzuzwe ukusebenza okuphezulu kakhulu ezimeni eziminyene.
4. 4K QAM
Ukushintshwa kwe-oda okuphezulu kakhulu kwe-Wi-Fi 6 kungu-1024-QAM, kuyilapho i-Wi-Fi 7 ingafinyelela ku-4K QAM. Ngale ndlela, izinga eliphakeme linganyuswa ukuze kwandiswe amandla okuphuma kanye nedatha, futhi isivinini sokugcina singafinyelela ku-30Gbps, okuyisivinini esiphindwe kathathu se-9.6Gbps WiFi 6 yamanje.
Ngamafuphi, i-Wi-Fi 7 iklanyelwe ukuhlinzeka ngesivinini esiphezulu kakhulu, umthamo ophezulu, kanye nokudluliswa kwedatha yokubambezeleka okuphansi ngokwandisa inani lemizila etholakalayo, ububanzi bedatha yokuthutha imoto ngayinye, nobubanzi bomzila ohambayo.
I-Wi-fi 7 Isula Indlela Ye-IoT Exhumeke Ngesivinini Eningi
Ngokombono wombhali, umnyombo wobuchwepheshe obusha be-Wi-Fi 7 awukona nje ukuthuthukisa izinga eliphakeme ledivayisi eyodwa, kodwa futhi ukunaka kakhulu ukudluliselwa okuhambisanayo okuphezulu ngaphansi kokusetshenziswa kwabasebenzisi abaningi (abasebenzisi abaningi. -Lane access) izimo, ngokungangabazeki ezihambisana nenkathi ezayo ye-inthanethi Yezinto. Okulandelayo, umbhali uzokhuluma ngezimo ze-iot ezizuzisa kakhulu:
1. I-inthanethi Yezimboni Yezinto
Enye yezingqinamba ezinkulu zobuchwepheshe be-iot ekukhiqizeni umkhawulokudonsa. Idatha eyengeziwe engakhulunywa ngesikhathi esisodwa, i-Iiot izoshesha futhi isebenze kahle. Endabeni yokuqapha ukuqinisekiswa kwekhwalithi ku-inthanethi Yezimboni Yezinto, isivinini senethiwekhi sibalulekile empumelelweni yezinhlelo zokusebenza zesikhathi sangempela. Ngosizo lwenethiwekhi ye-Iiot esheshayo, izexwayiso zesikhathi sangempela zingathunyelwa ngesikhathi ukuze kuphenduleke ngokushesha ezinkingeni ezifana nokuhluleka komshini okungalindelekile nokunye ukuphazamiseka, ukuthuthukisa kakhulu ukukhiqiza nokusebenza kahle kwamabhizinisi okukhiqiza nokunciphisa izindleko ezingadingekile.
2. I-Edge Computing
Njengoba isidingo sabantu sokusabela ngokushesha kwemishini ehlakaniphile nokuvikeleka kwedatha ye-inthanethi Yezinto siya ngokuya sikhuphuka, i-cloud computing izovama ukubandlululwa esikhathini esizayo. I-Edge computing imane ibhekisela ekwenzeni ikhompuyutha ohlangothini lomsebenzisi, okungadingi nje kuphela amandla aphezulu e-computing ohlangothini lomsebenzisi, kodwa futhi nesivinini sokudlulisa idatha esiphezulu esanele ngasohlangothini lomsebenzisi.
3. I-AR/VR egxilile
I-Immersive VR idinga ukwenza impendulo esheshayo efanayo ngokuya ngezenzo zesikhathi sangempela zabadlali, okudinga ukubambezeleka okuphansi kakhulu kwenethiwekhi. Uma uhlezi unikeza abadlali impendulo enokunensa yebhithi elilodwa, kusho ukuthi ukucwiliswa emanzini kuwumbumbulu. I-Wi-fi 7 kulindeleke ukuthi ixazulule le nkinga futhi isheshise ukwamukelwa kwe-AR/VR egxilile.
4. Ukuvikeleka okuhlakaniphile
Ngokuthuthuka kokuvikeleka okuhlakaniphile, isithombe esidluliswa amakhamera ahlakaniphile siya ngokuya sicaca, okusho ukuthi idatha eguquguqukayo edluliswayo iya iba nkudlwana, futhi izidingo zomkhawulokudonsa nesivinini senethiwekhi nazo ziya ngokuya ziphakama. Ku-LAN, i-WIFI 7 cishe iyindlela engcono kakhulu.
Ekugcineni
I-Wi-fi 7 yinhle, kodwa okwamanje, amazwe abonisa izimo zengqondo ezihlukene zokuthi avumele ukufinyelela kwe-WiFi ebhendini ye-6GHz (5925-7125mhz) njengebhendi engenalayisense. Izwe kusamele linikeze inqubomgomo ecacile ku-6GHz, kodwa noma ngabe ibhendi ye-5GHz kuphela itholakala, i-Wi-Fi 7 isengahlinzeka ngezinga eliphezulu lokudlulisela elingu-4.3Gbps, kuyilapho i-Wi-Fi 6 isekela kuphela isivinini sokulanda esiphezulu esingu-3Gbps. uma ibhendi ye-6GHz itholakala. Ngakho-ke, kulindeleke ukuthi i-Wi-Fi 7 izodlala indima ebaluleke kakhulu kuma-Lans anesivinini esikhulu ngokuzayo, isize amadivayisi ahlakaniphile ngokwengeziwe ukuthi agweme ukubanjwa ikhebula.
