Pakutanga kwaOctober, Wi-Fi Alliance yakazivisa shanduro itsva ye Wi-Fi standard - Wi-Fi 6. Kusunungurwa kwayo kwakarongerwa kupera kwe2019. Vagadziri vakachinja maitiro avo ekutumidza mazita - kutsiva akajairwa magadzirirwo se802.11ax nenhamba imwechete. Ngatione kuti chii chimwe chitsva.

Sei vakachinja zita
By vagadziri vakajairwa, nzira nyowani yekupa mazita ichaita kuti mazita eWi-Fi zviyero anzwisiswe kune vakawanda vateereri.
Iyo Wi-Fi Alliance inocherekedza kuti ikozvino zvakajairika kuti vashandisi vatenge malaptops anotsigira chiyero icho router yavo yekumba isingashande nayo. Nekuda kweizvozvo, mudziyo mutsva unoenda kunzira dzekudzokera kumashure - kuchinjanisa data kunoitwa uchishandisa chiyero chekare. Mune zvimwe zviitiko, izvi zvinogona kuderedza mitengo yekufambisa data ne50-80%.
Kuti uratidze zvakajeka kuti ndeupi chiyero ichi kana iyo gadget inotsigira, iyo Alliance yakagadzira chiratidzo chitsva - chiratidzo cheWi-Fi, pamusoro payo nhamba inoenderana inoratidzwa.
Ndeapi mabasa akapihwa neWi-Fi 6?
Tsanangudzo yakadzama yezvese maficha uye maitiro eWi-Fi 6 anogona kuwanikwa mukati (kuigamuchira, unofanirwa kuzadza fomu) kana . Zvadaro, tichataura pamusoro pezvitsva zvikuru.
Inotsigira 2,4 uye 5 GHz mabhendi. Nenzira yakanaka, kutsigirwa panguva imwe chete ye2,4 uye 5 GHz kuchabatsira kuwedzera nhamba yezviitiko zve-multi-device. Zvisinei, mukuita izvi zvakanakira zvingasava zvinobatsira. Kune akawanda akawandisa enhaka midziyo pamusika (iyo inotsigira 2,4 GHz), saka zvishandiso zvitsva zvinogara zvichishanda mukuenderana modhi.
OFDMA rutsigiro. Tiri kutaura nezve Orthogonal Frequency Division Multiple Access (OFDMA). Chaizvoizvo, tekinoroji iyi i "multi-user" vhezheni . Iyo inokutendera iwe kugovera iyo chiratidzo mu frequency subcarriers uye sarudza mapoka avo ekugadzirisa ega ega data hova.
Izvi zvinokutendera kuti utepfenyure data kune akati wandei Wi-Fi 6 vatengi kamwechete paavhareji yekumhanya. Asi pane imwe caveat: vese vatengi ava vanofanira kutsigira Wi-Fi 6. Nokudaro, "yekare" gadget, zvakare, inosara shure.
Kubatana uye OFDMA. MuWi-Fi 5 (iyi mumazita ekare, ayo akatenderwa muna 2014) tekinoroji (Multiple Input Multiple Output) yakabvumira data kutepfenyurwa kune vatengi vana vachishandisa subcarriers dzakasiyana. MuWi-Fi 6, nhamba yezvinobvira yekubatanidza mudziyo yakapetwa kaviri kusvika masere.
Iyo Wi-Fi Alliance inoti MU-MIMO masisitimu akasanganiswa neOFDMA achabatsira kuronga akawanda-mushandisi data kutapurirana nekumhanya kunosvika 11 Gbit/s pamusoro. . Ichi chigumisiro bvunzo zvishandiso paCES 2018. Zvisinei, vagari veHacker News kuti akajairwa gadget (laptops, smartphones) haazooni kumhanya kwakadaro.
Panguva yekuedzwa kuCES tri-band router D-Link DIR-X9000, uye 11 Gbps ndiyo hwerengedzo yehuwandu hwehuwandu hwekutamisa data mumatanho matatu. Vagari veHacker News vanocherechedza kuti kazhinji michina inoshandisa chiteshi chimwe chete, saka data inoshambadzirwa nekumhanya kunosvika 4804 Mbit/s.
Target Wake Nguva basa. Ichabvumira zvishandiso kuti zvipinde muhope mode uye "kumuka" zvinoenderana nehurongwa. Target Wake Time inosarudza nguva iyo mudziyo usingaite uye kana uchishanda. Kana iyo gadget isingafambisi data panguva yakatarwa yenguva (somuenzaniso, husiku), iyo Wi-Fi yekubatanidza "inorara," iyo inochengetedza simba rebhatiri uye inoderedza network kusangana.
Pachishandiso chega chega, "yakatarisa nguva yekumuka" inosetwa - iyo nguva iyo iyo ine mamiriro laptop inogara ichitumira data (semuenzaniso, panguva yebhizinesi maawa pamakambani network). Munguva dzakadai, modhi yekurara haizoshandiswe.

Wi-Fi 6 ichashandiswa kupi?
Sekureva kwevagadziri, tekinoroji ichave yakakosha kana uchiendesa yakakwirira-density Wi-Fi network. Mhinduro dzakasarudzwa dzakadai seMU-MIMO neOFDMA dzichavandudza kunaka kwekutaurirana muzvifambiso zvevoruzhinji, nharaunda dzemakambani, mashopu, mahotera kana nhandare.
Nekudaro, nhengo dzeIT nharaunda Wi-Fi 6 ine kukanganisa kukuru mumamiriro ekuita tekinoroji. Mhedzisiro inobatika yeshanduko kuenda kuWi-Fi 6 inozoonekwa chete kana ese maturusi etiweki akatsigira chiyero chitsva. Uye zvechokwadi pachava nematambudziko neizvi.
Ngatikuyeuchidzei kuti kuburitswa kweWi-Fi 6 kuchaitika mukupera kwa2019.
