Ekuqaleni kuka-Oktobha, i-Wi-Fi Alliance yazisa inguqu entsha yomgangatho we-Wi-Fi - i-Wi-Fi 6. Ukukhutshwa kwayo kucwangciselwe ukuphela kwe-2019. Abaphuhlisi batshintshe indlela yabo yokubiza amagama-ukutshintsha iindlela zoyilo eziqhelekileyo ezifana ne-802.11ax ngamanani omnye. Makhe sibone ukuba yeyiphi enye into entsha.

Kwakutheni ukuze balitshintshe igama
Ngu abaphuhlisi abasemgangathweni, indlela entsha yokubiza amagama iya kwenza amagama emigangatho ye-Wi-Fi aqondeke kubaphulaphuli ababanzi.
I-Wi-Fi Alliance iphawula ukuba iqhelekile ngoku kubasebenzisi ukuba bathenge iilaptops ezixhasa umgangatho irutha yasekhaya engenakusebenza ngawo. Ngenxa yoko, isixhobo esitsha sibhenela kwiindlela zokubuyela ngasemva - utshintshiselwano lwedatha lwenziwa kusetyenziswa umgangatho omdala. Kwezinye iimeko, oku kunokunciphisa amazinga okudluliselwa kwedatha ngama-50-80%.
Ukubonisa ngokucacileyo ukuba yiyiphi umgangatho le okanye igajethi exhasayo, i-Alliance iphuhlise ukumakisha okutsha - i-icon ye-Wi-Fi, phezu kwayo inombolo ehambelanayo ibonakaliswe.
Yeyiphi imisebenzi ebonelelwe yiWi-Fi 6?
Inkcazo eneenkcukacha yazo zonke iimpawu kunye neempawu ze-Wi-Fi 6 inokufumaneka (ukuyifumana, kufuneka ugcwalise ifomu) okanye . Okulandelayo, siza kuthetha ngezinto ezintsha eziphambili.
Ixhasa iibhendi ze-2,4 kunye ne-5 GHz. Ngokufanelekileyo, inkxaso ngaxeshanye ye-2,4 kunye ne-5 GHz iya kunceda ukwandisa inani leemeko zezixhobo ezininzi. Nangona kunjalo, ekusebenzeni le nzuzo isenokungabi luncedo. Kukho izixhobo ezininzi zelifa kwimarike (exhasa i-2,4 GHz), ngoko ke izixhobo ezitsha ziya kusebenza rhoqo kwimodi yokuhambelana.
Inkxaso ye-OFDMA. Sithetha nge-Orthogonal Frequency Division Multiple Access (OFDMA). Ngokusisiseko, le teknoloji yinguqulelo "yabasebenzisi abaninzi". . Ikuvumela ukuba wahlule isiginali ibe yi-frequency subcarriers kwaye ukhethe amaqela abo ukusetyenzwa kwemijelo yedatha nganye.
Oku kuya kukuvumela ukuba usasaze idatha nge-synchronously kubathengi abaninzi be-Wi-Fi 6 kanye ngesantya esiphakathi. Kodwa kukho i-caveat enye: bonke aba bathengi kufuneka baxhase i-Wi-Fi 6. Ngoko ke, iigajethi "ezindala", kwakhona, zishiywe ngasemva.
Ukudibana kunye ne-OFDMA. Kwi-Wi-Fi 5 (le kwizikhundla zakudala, ezavunywa ngo-2014) iteknoloji (IiPhumo eziNyezo eziNinzi) zivumele idatha ukuba isasazwe kubathengi abane kusetyenziswa ii-subcarriers ezahlukeneyo. Kwi-Wi-Fi 6, inani loqhagamshelo lwesixhobo esinokwenzeka liphindwe kabini ukuya kwisibhozo.
I-Wi-Fi Alliance ithi iinkqubo ze-MU-MIMO ezidityaniswa ne-OFDMA ziya kunceda ukuququzelela ukuhanjiswa kwedatha yabasebenzisi abaninzi ngesantya ukuya kuthi ga kwi-11 Gbit/s ngaphezulu. . Esi siphumo izixhobo uvavanyo CES 2018. Noko ke, abahlali Hacker News ukuba izixhobo eziqhelekileyo (iilaptops, ii-smartphones) aziyi kubona isantya esinjalo.
Ngexesha lovavanyo kwi-CES i-tri-band router D-Link DIR-X9000, kunye ne-11 Gbps isixa sezinga eliphezulu lokudluliswa kwedatha kumajelo amathathu. Abahlali beendaba zeHacker baqaphela ukuba izixhobo ezininzi zihlala zisebenzisa itshaneli enye kuphela, ngoko ke idatha iya kusasazwa ngesantya ukuya kuthi ga kwi-4804 Mbit / s.
Injongo yokuVusa ixesha lomsebenzi. Iya kuvumela izixhobo ukuba zingene kwimodi yokulala kwaye "zivuke" ngokweshedyuli. Ixesha ekujoliswe kulo limisela ixesha apho isixhobo singasebenzi kwaye sisebenza nini. Ukuba igajethi ayihambisi idatha ngexesha elithile (umzekelo, ebusuku), uxhumano lwayo lwe-Wi-Fi "lulala," olugcina amandla ebhetri kwaye lunciphisa ukuxinana kwenethiwekhi.
Kwisixhobo ngasinye, "ixesha lokuvuka ekujoliswe kulo" lisetiwe - ixesha apho ilaptop enemiqathango ihlala ithumela idatha (umzekelo, ngexesha leeyure zomsebenzi kuthungelwano lweshishini). Ngamaxesha anjalo, imo yokulala ayizukwenziwa isebenze.

Iza kusetyenziswa phi i-Wi-Fi 6?
Ngokutsho kwabaphuhlisi, iteknoloji iya kuba luncedo xa uhambisa amanethiwekhi e-Wi-Fi aphezulu. Izisombululo ezikhethiweyo ezifana ne-MU-MIMO kunye ne-OFDMA ziya kuphucula umgangatho wonxibelelwano kwizithuthi zikawonke-wonke, iindawo zenkampani, iindawo zokuthenga, iihotele okanye amabala emidlalo.
Nangona kunjalo, amalungu oluntu lwe-IT I-Wi-Fi 6 inomngcipheko omkhulu kumxholo wokuphunyezwa kweteknoloji. Umphumo obonakalayo wenguqu kwi-Wi-Fi 6 iya kubonakala kuphela ukuba zonke izixhobo zenethiwekhi zixhasa umgangatho omtsha. Kwaye ngokuqinisekileyo kuya kubakho iingxaki kule nto.
Masikukhumbuze ukuba ukukhutshwa kwe-Wi-Fi 6 kuya kwenzeka ekupheleni kwe-2019.
