Ngo-2018, i-WiFi Alliance yamemezela i-WiFi 6, isizukulwane esisha, esisheshayo se-WiFi esakha ngohlaka oludala (ubuchwepheshe be-802.11ac).Manje, ngemva kokuqala ukuqinisekisa amadivayisi ngo-September ka-2019, isifikile nohlelo olusha lokuqamba amagama okulula ukuluqonda kunegama elidala.
Ngolunye usuku esikhathini esizayo esiseduze, eziningi zemishini yethu exhunyiwe izonikwa amandla i-WiFi 6.Isibonelo, i-Apple iPhone 11 ne-Samsung Galaxy Notes isivele isekela i-WiFi 6, futhi sibone amarutha e-Wi-Fi CERTIFIED 6™ ephuma kamuva nje.Yini esingayilindela ngezinga elisha?
Ubuchwepheshe obusha bunikeza ukuthuthukiswa kokuxhumeka kumadivayisi anikwe amandla we-WiFi 6 kuyilapho kugcinwa ukuhambisana okubuyela emuva kumadivayisi amadala.Isebenza kangcono ezindaweni eziminyana kakhulu, isekela umthamo owengeziwe wamadivayisi, ithuthukisa impilo yebhethri yamadivayisi ahambisanayo, futhi iziqhayisa ngezilinganiso eziphakeme zokudluliswa kwedatha kunangaphambi kwayo.
Nakhu ukuhlukaniswa kwezindinganiso zangaphambilini.Qaphela ukuthi izinguqulo ezindala ziqokwe ngezikimu zokuqamba ezibuyekeziwe, nokho, azisasetshenziswa kabanzi:
WiFi 6ukukhomba amadivayisi asekela i-802.11ax (ekhishwe ngo-2019)
WiFi 5ukuhlonza amadivayisi asekela i-802.11ac (ekhishwe ngo-2014)
WiFi 4ukukhomba amadivayisi asekela i-802.11n (ekhishwe ngo-2009)
WiFi 3ukuhlonza amadivayisi asekela i-802.11g (ekhishwe ngo-2003)
WiFi 2ukukhomba amadivayisi asekela i-802.11a (ekhishwe ngo-1999)
I-WiFi 1ukukhomba amadivayisi asekela i-802.11b (ekhishwe ngo-1999)
Isivinini se-WiFi 6 vs WiFi 5
Okokuqala, ake sikhulume nge-throughput yetiyori.Njengoba i-Intel yakubeka, "i-Wi-Fi 6 iyakwazi ukuphumela ngaphandle okungu-9.6 Gbps eziteshini eziningi, uma kuqhathaniswa no-3.5 Gbps ku-Wi-Fi 5."Ngokombono, irutha enekhono ye-WiFi 6 ingashaya isivinini esingaphezu kuka-250% ngokushesha kunamadivayisi amanje e-WiFi 5.
Amandla esivinini esiphezulu se-WiFi 6 sibonga ubuchwepheshe obufana ne-orthogonal frequency division multiple access (OFDMA);MU-MIMO;i-beamforming, eyenza amanani edatha aphezulu ebangeni elinikeziwe ukuze kukhuliswe umthamo wenethiwekhi;kanye ne-1024 quadrature amplitude modulation (QAM), okwandisa ukudlula kokusetshenziswa okukhulayo, komkhawulokudonsa ngokufaka ikhodi idatha eyengeziwe ngenani elifanayo le-spectrum.
Bese kuba khona i-WiFi 6E, izindaba ezinhle zokuminyana kwenethiwekhi
Okunye okungeziwe ku-WiFi "ukuthuthukiswa" yi-WiFi 6E.Ngomhla zingama-23 kuMbasa, i-FCC yenza isinqumo esiyingqopha-mlando sokuvumela ukusakazwa ngaphandle kwelayisense ngebhendi ye-6GHz.Lokhu kusebenza ngendlela efanayo nendlela umzila wakho osekhaya ongasakaza ngayo ngamabhendi angu-2.4GHz kanye no-5GHz.Manje, amadivayisi anamandla e-WiFi 6E anebhendi entsha enesethi entsha yeziteshi ze-WiFi ukuze kuncishiswe ukuminyana kwenethiwekhi namasiginali awehlile:
"I-6 GHz ibhekana nokushoda kwe-Wi-Fi spectrum ngokunikeza ama-spectrum blocks ukuze kufakwe iziteshi ezingu-14 ezengeziwe ezingu-80 MHz kanye neziteshi ezingu-7 ezengeziwe ezingu-160 MHz ezidingekayo ezinhlelweni zokusebenza ezinomkhawulokudonsa ophezulu ezidinga ukudluliswa kwedatha okusheshayo njengokusakazwa kwevidiyo enencazelo ephezulu kanye neqiniso elibonakalayo. . Amadivayisi e-Wi-Fi 6E azosebenzisa iziteshi ezibanzi namandla angeziwe ukuze alethe ukusebenza kwenethiwekhi okukhulu."- I-WiFi Alliance
Lesi sinqumo sicishe siphindaphinde kane inani lomkhawulokudonsa elitholakalayo ukuze lisetshenziswe i-WiFi kanye namadivayisi e-IoT—1,200MHz yesibonisi kubhendi ye-6GHz etholakalayo ukuze isetshenziswe ngaphandle kwelayisensi.Ukubeka lokhu ngombono ofanele, amabhendi e-2.4GHz kanye ne-5GHz ehlanganisiwe njengamanje asebenza ngaphakathi kwe-spectrum engaba ngu-400MHz engagunyaziwe.
