Uyafuna ukwazi ukuthi isoka lakho liyakuthanda ukudlala imidlalo yekhompyutha? Ake ngikwabelane ngecebiso, ungahlola ukuthi ikhompyutha yalo ixhumene ngekhebula lenethiwekhi noma cha. Ngoba abafana banezidingo eziphezulu zesivinini senethiwekhi kanye nokubambezeleka lapho bedlala imidlalo, futhi iningi le-WiFi yasekhaya yamanje alikwazi ukwenza lokhu noma ngabe isivinini senethiwekhi ye-broadband sishesha ngokwanele, ngakho abafana abavame ukudlala imidlalo bavame ukukhetha ukufinyelela okunezintambo ku-broadband ukuqinisekisa indawo yenethiwekhi ezinzile nesheshayo.
Lokhu futhi kukhombisa izinkinga zokuxhumeka kwe-WiFi: ukubambezeleka okuphezulu kanye nokungazinzi, okusobala kakhulu uma kwenzeka kubasebenzisi abaningi ngesikhathi esisodwa, kodwa lesi simo sizothuthuka kakhulu ngokufika kwe-WiFi 6. Lokhu kungenxa yokuthi i-WiFi 5, esetshenziswa abantu abaningi, isebenzisa ubuchwepheshe be-OFDM, kuyilapho i-WiFi 6 isebenzisa ubuchwepheshe be-OFDMA. Umehluko phakathi kwalezi zindlela ezimbili ungaboniswa ngemidwebo:
Emgwaqweni ONGAKWAZI ukwamukela imoto eyodwa kuphela, i-OFDMA ingadlulisela ama-terminal amaningi ngasikhathi sinye, isuse imigqa nokuminyana, ITHUTHUKISA UKUSEBENZA KAHLE FUTHI IYEHLISE ukubambezeleka. I-OFDMA ihlukanisa isiteshi esingenantambo sibe yiziteshi eziningi ezincane kusizinda semvamisa, ukuze abasebenzisi abaningi bakwazi ukudlulisa idatha ngasikhathi sinye ngesikhathi ngasinye, okuthuthukisa ukusebenza kahle futhi kunciphisa ukubambezeleka kokumiswa komugqa.
I-WIFI 6 ibilokhu ithandwa kakhulu selokhu yasungulwa, njengoba abantu befuna amanethiwekhi asekhaya angenantambo amaningi. Ama-terminal e-Wi-Fi 6 angaphezu kwezigidigidi ezimbili athunyelwe ekupheleni kuka-2021, okwenza kube ngaphezu kuka-50% wazo zonke izimpahla ze-Wi-Fi, futhi lelo nani lizokhula lifinyelele ku-5.2 billion ngo-2025, ngokusho kwenkampani yokuhlaziya i-IDC.
Nakuba i-Wi-Fi 6 igxile kokuhlangenwe nakho komsebenzisi ezimweni ezinabantu abaningi, kuye kwavela izinhlelo zokusebenza ezintsha eminyakeni yamuva nje ezidinga i-throughput ephezulu kanye nokubambezeleka, njengevidiyo ye-ultra-high-definition efana namavidiyo e-4K kanye ne-8K, ukusebenza kude, i-video conferencing eku-inthanethi, kanye nemidlalo ye-VR/AR. Izinkampani ezinkulu zobuchwepheshe nazo ziyazibona lezi zinkinga, kanti i-Wi-Fi 7, enikeza isivinini esikhulu, umthamo ophezulu kanye nokubambezeleka okuphansi, iyaqhubeka. Ake sithathe i-Wi-Fi 7 ye-Qualcomm njengesibonelo futhi sixoxe ngalokho i-Wi-Fi 7 ekuthuthukisile.
I-Wi-fi 7: Konke ngenxa ye-Low Latency
1. I-bandwidth Ephakeme
Futhi, thatha imigwaqo. I-Wi-fi 6 isekela kakhulu amabhendi angu-2.4ghz kanye no-5ghz, kodwa umgwaqo ongu-2.4ghz wabelwa yi-Wi-Fi yakuqala kanye nezinye ubuchwepheshe obungenantambo njenge-Bluetooth, ngakho-ke uba matasa kakhulu. Imigwaqo engu-5GHz ibanzi futhi ayixinene kakhulu kune-2.4ghz, okuhunyushwa ngesivinini esisheshayo kanye nomthamo owengeziwe. I-Wi-fi 7 isekela ngisho nebhendi engu-6GHz phezu kwala mabhendi amabili, yandisa ububanzi besiteshi esisodwa kusukela ku-Wi-Fi 6's 160MHz kuya ku-320MHz (engathwala izinto eziningi ngesikhathi). Ngaleso sikhathi, i-Wi-Fi 7 izoba nesilinganiso sokudlulisa esiphezulu esingaphezu kuka-40Gbps, esiphindwe kane kune-Wi-Fi 6E.
2. Ukufinyelela kwezixhumanisi eziningi
Ngaphambi kwe-Wi-Fi 7, abasebenzisi babesebenzisa umgwaqo owodwa kuphela ofanela izidingo zabo, kodwa isixazululo se-Qualcomm's Wi-Fi 7 sidlula imingcele ye-Wi-Fi nakakhulu: esikhathini esizayo, wonke ama-band amathathu azokwazi ukusebenza ngesikhathi esisodwa, okunciphisa ukuminyana. Ngaphezu kwalokho, ngokusekelwe kumsebenzi we-multi-link, abasebenzisi bangaxhuma ngeziteshi eziningi, besebenzisa lokhu ukuze bagweme ukuminyana. Isibonelo, uma kukhona ithrafikhi kwesinye seziteshi, idivayisi ingasebenzisa esinye isiteshi, okuholela ekubambezelekeni okuphansi. Okwamanje, kuye ngokutholakala kwezifunda ezahlukene, i-multi-link ingasebenzisa iziteshi ezimbili kubhendi ye-5GHz noma inhlanganisela yeziteshi ezimbili kubhendi ye-5GHz ne-6GHz.
3. Isiteshi Esihlanganisiwe
Njengoba kushiwo ngenhla, i-bandwidth ye-Wi-Fi 7 inyuswe yaba yi-320MHz (ububanzi bemoto). Ku-band ye-5GHz, ayikho i-band eqhubekayo ye-320MHz, ngakho-ke yisifunda se-6GHz kuphela esingasekela le modi eqhubekayo. Ngomsebenzi we-multi-link ohambisanayo we-bandwidth ephezulu, ama-frequency band amabili angahlanganiswa ngesikhathi esisodwa ukuze kuqoqwe i-throughput yeziteshi ezimbili, okungukuthi, amasignali amabili e-160MHz angahlanganiswa ukuze kwakhiwe isiteshi esisebenzayo se-320MHz (ububanzi obunwetshiwe). Ngale ndlela, izwe elifana nelethu, elingakabelani i-spectrum ye-6GHz, lingahlinzeka nangesiteshi esibanzi ngokwanele esisebenzayo ukuze kufezwe i-throughput ephezulu kakhulu ezimweni ezixinene.
4. 4K QAM
Ukuguqulwa kwe-oda okuphezulu kakhulu kwe-Wi-Fi 6 yi-1024-QAM, kanti i-Wi-Fi 7 ingafinyelela ku-4K QAM. Ngale ndlela, izinga eliphakeme kakhulu lingakhushulwa ukuze kwandiswe umthamo wokudlulisa kanye nedatha, futhi ijubane lokugcina lingafinyelela ku-30Gbps, okuyisivinini esiphindwe kathathu kune-9.6Gbps WiFi 6 yamanje.
Ngamafuphi, i-Wi-Fi 7 yenzelwe ukuhlinzeka ngesivinini esikhulu kakhulu, umthamo ophezulu, kanye nokudluliswa kwedatha okuphansi ngokwandisa inani lemizila etholakalayo, ububanzi bemoto ngayinye ethutha idatha, kanye nobubanzi bomzila ohambayo.
I-Wi-fi 7 Ivula Indlela Ye-IoT Enesivinini Esikhulu Exhunywe Kaningi
Ngokombono wombhali, ingqikithi yobuchwepheshe obusha be-Wi-Fi 7 akukhona nje ukuthuthukisa izinga eliphezulu ledivayisi eyodwa, kodwa futhi nokunaka kakhulu ukudluliswa kwejubane eliphezulu ngesikhathi esisodwa ngaphansi kokusetshenziswa kwezimo zabasebenzisi abaningi (ukufinyelela kwemizila eminingi), okungangabazeki ukuthi kuhambisana nenkathi ezayo ye-Internet of Things. Okulandelayo, umbhali uzokhuluma ngezimo ze-iot ezizuzisa kakhulu:
1. I-inthanethi Yezinto Zezimboni
Enye yezingqinamba ezinkulu zobuchwepheshe be-iot ekukhiqizeni i-bandwidth. Uma idatha eminingi ingadluliselwa ngesikhathi esisodwa, i-Iiot izoba ngokushesha futhi isebenze kahle kakhulu. Endabeni yokuqapha ikhwalithi ku-Industrial Internet of Things, isivinini senethiwekhi sibalulekile empumelelweni yezinhlelo zokusebenza zesikhathi sangempela. Ngosizo lwenethiwekhi ye-Iiot esheshayo, izexwayiso zesikhathi sangempela zingathunyelwa ngesikhathi ukuze kuphendulwe ngokushesha ezinkingeni ezifana nokwehluleka kwemishini okungalindelekile nokunye ukuphazamiseka, okuthuthukisa kakhulu umkhiqizo kanye nokusebenza kahle kwamabhizinisi okukhiqiza kanye nokunciphisa izindleko ezingadingekile.
2. Ikhompyutha Yomphetho
Njengoba isidingo sabantu sokuphendula okusheshayo kwemishini ehlakaniphile kanye nokuphepha kwedatha kwe-Intanethi Yezinto kukhuphuka kakhulu, i-cloud computing izothambekela ekuncishweni isikhathi esizayo. I-Edge computing imane ibhekisela ekubaleni ohlangothini lomsebenzisi, okudinga hhayi nje amandla aphezulu ekubaleni ohlangothini lomsebenzisi, kodwa futhi nesivinini sokudlulisa idatha esiphezulu ngokwanele ohlangothini lomsebenzisi.
3. I-AR/VR ejulile
I-VR ejulile idinga ukwenza impendulo esheshayo ehambisanayo ngokwezenzo zabadlali ngesikhathi sangempela, okudinga ukubambezeleka okuphansi kakhulu kwenethiwekhi. Uma uhlala unikeza abadlali impendulo emfushane, khona-ke ukucwilisa kuyinkohliso. I-Wi-fi 7 kulindeleke ukuthi ixazulule le nkinga futhi isheshise ukwamukelwa kwe-AR/VR ejulile.
4. Ukuphepha okuhlakaniphile
Ngokuthuthuka kokuphepha okuhlakaniphile, isithombe esidluliselwa ngamakhamera ahlakaniphile siya ngokuya siba nencazelo ephezulu, okusho ukuthi idatha enamandla edluliselwayo iya ngokuya iba nkulu, kanti nezidingo ze-bandwidth kanye nesivinini senethiwekhi nazo ziya ngokuya ziphakama. Ku-LAN, i-WIFI 7 cishe iyindlela engcono kakhulu.
Ekugcineni
I-Wi-fi 7 ilungile, kodwa okwamanje, amazwe abonisa imibono ehlukene yokuthi kufanele yini avumele ukufinyelela kwe-WiFi kubhendi ye-6GHz (5925-7125mhz) njengebhendi engenalayisensi. Izwe alikakanikezi inqubomgomo ecacile ku-6GHz, kodwa noma ngabe kutholakala ibhendi ye-5GHz kuphela, i-Wi-Fi 7 isengakwazi ukunikeza izinga eliphezulu lokudlulisa 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 asheshayo esikhathini esizayo, isize amadivayisi amaningi ahlakaniphile ukuthi agweme ukubanjwa yikhebula.
