Ekuqaleni kuka-Okthoba, i-Wi-Fi Alliance yamemezela inguqulo entsha yezinga le-Wi-Fi - Wi-Fi 6. Ukukhishwa kwayo kuhlelelwe ukuphela kuka-2019. Abathuthukisi bashintshe indlela yabo yokuqamba amagama - esikhundleni semiklamo evamile efana ne-802.11ax ngezinombolo ezizodwa. Ake sithole ukuthi yini enye entsha.

Kungani beshintshe igama
Ngu abathuthukisi abajwayelekile, indlela entsha yokuqamba izokwenza amagama wamazinga e-Wi-Fi aqondakale kubabukeli abaningi.
I-Wi-Fi Alliance iphawula ukuthi sekuyinsakavukela umchilo wesidwaba ukuthi abasebenzisi bathenge amakhompyutha aphathekayo asekela izinga umzila wabo wasekhaya ongakwazi ukusebenza ngalo. Ngenxa yalokho, idivayisi entsha iphendukela ezindleleni ezihambisanayo ezibuyela emuva - ukushintshaniswa kwedatha kwenziwa kusetshenziswa izinga elidala. Kwezinye izimo, lokhu kungehlisa izinga lokudluliswa kwedatha ngo-50–80%.
Ukukhombisa ngokucacile ukuthi iyiphi indinganiso lena noma leyo gajethi esekelayo, i-Alliance ithuthukise ukumaka okusha - isithonjana se-Wi-Fi, phezu kwalokho inombolo ehambisanayo ekhonjisiwe.
Yimiphi imisebenzi ehlinzekwe yi-Wi-Fi 6?
Incazelo enemininingwane yazo zonke izici nezici ze-Wi-Fi 6 ingatholakala ku (ukuze uyithole, udinga ukugcwalisa ifomu) noma . Okulandelayo, sizokhuluma ngezinqubo ezintsha eziyinhloko.
Isekela amabhendi angu-2,4 no-5 GHz. Ngokufanelekile, ukusekelwa ngasikhathi sinye kwe-2,4 kanye ne-5 GHz kuzosiza ukwandisa inani lezimo zamadivayisi amaningi. Nokho, ekusebenzeni le nzuzo ingase ingabi wusizo. Kunamadivayisi amaningi kakhulu efa emakethe (asekela i-2,4 GHz), ngakho-ke amadivayisi amasha azosebenza njalo kumodi ehambelanayo.
Ukusekelwa kwe-OFDMA. Sikhuluma nge-Orthogonal Frequency Division Multiple Access (OFDMA). Empeleni, lobu buchwepheshe buyinguqulo "yabasebenzisi abaningi". . Ikuvumela ukuthi uhlukanise isignali ibe yizinkampani ezincanyana zefrikhwensi bese ukhetha amaqembu azo ukuze kucutshungulwe imifudlana yedatha ngayinye.
Lokhu kuzokuvumela ukuthi usakaze idatha ngokuhambisanayo kumaklayenti amaningana e-Wi-Fi 6 ngesikhathi esisodwa ngesivinini esimaphakathi. Kodwa kune-caveat eyodwa: wonke lawa maklayenti kufanele asekele i-Wi-Fi 6. Ngakho-ke, amagajethi "amadala", futhi, ashiywe ngemuva.
Ukusebenzisana kanye ne-OFDMA. Ku-Wi-Fi 5 (lokhu ekuqokweni amadala, okwavunywa ngo-2014) ubuchwepheshe (I-Multiple Input Multiple Output) ivumele idatha ukuthi isakazwe kumaklayenti amane kusetshenziswa izinkampani zenethiwekhi ezihlukile. Ku-Wi-Fi 6, inani loxhumo lwedivayisi okungenzeka liphindwe kabili ukuze libe yisishiyagalombili.
I-Wi-Fi Alliance ithi izinhlelo ze-MU-MIMO ezihlanganiswe ne-OFDMA zizosiza ukuhlela ukudluliswa kwedatha yabasebenzisi abaningi ngesivinini esingafika ku-11 Gbit/s ngaphezulu. . Lo mphumela ukuhlola amadivayisi CES 2018. Nokho, izakhamuzi Hacker News ukuthi amagajethi ajwayelekile (ama-laptops, ama-smartphone) ngeke abone isivinini esinjalo.
Ngesikhathi sokuhlolwa e-CES Irutha ye-tri-band D-Link DIR-X9000, kanye ne-11 Gbps iyisamba samazinga aphezulu okudlulisa idatha eziteshini ezintathu. Izakhamuzi ze-Hacker News ziphawula ukuthi ngokuvamile amadivayisi asebenzisa isiteshi esisodwa kuphela, ngakho-ke idatha izosakazwa ngesivinini esingafika ku-4804 Mbit/s.
Umsebenzi we-Target Wake Time. Izovumela amadivayisi ukuthi angene kumodi yokulala futhi "avuke" ngokuya ngeshejuli. Isikhathi Sokuvuka Okuqondiwe sinquma isikhathi lapho idivayisi ingasebenzi nalapho isebenza. Uma igajethi ingadluliseli idatha phakathi nenkathi ethile yesikhathi (isibonelo, ebusuku), uxhumo lwayo lwe-Wi-Fi “lulala,” okonga amandla ebhethri futhi kunciphisa ukuminyana kwenethiwekhi.
Kudivayisi ngayinye, “isikhathi sokuvuka esiqondiwe” siyasethwa - isikhathi lapho ikhompuyutha ephathekayo enemibandela ihlezi ithumela idatha (isibonelo, phakathi namahora ebhizinisi kumanethiwekhi ezinkampani). Phakathi nezikhathi ezinjalo, imodi yokulala ngeke yenziwe isebenze.

Izosetshenziswa kuphi i-Wi-Fi 6?
Ngokusho kwabathuthukisi, ubuchwepheshe buzoba usizo lapho kuthunyelwa amanethiwekhi we-Wi-Fi asondelene kakhulu. Izixazululo ezikhethiwe ezifana ne-MU-MIMO kanye ne-OFDMA zizothuthukisa ikhwalithi yokuxhumana kwezokuthutha zomphakathi, izindawo zezinkampani, izitolo ezinkulu, amahhotela noma izinkundla.
Nokho, amalungu omphakathi IT I-Wi-Fi 6 inokungalungi okukhulu kumongo wokusetshenziswa kobuchwepheshe. Umphumela obambekayo wokushintshela ku-Wi-Fi 6 uzobonakala kuphela uma wonke amadivaysi enethiwekhi esekela izinga elisha. Futhi nakanjani kuzoba nezinkinga ngalokhu.
Ake sikukhumbuze ukuthi ukukhishwa kwe-Wi-Fi 6 kuzokwenzeka ekupheleni kuka-2019.
