Kuenzaniswa nezvizvarwa zvakapfuura zveWiFi tekinoroji, iwo makuru maficha echizvarwa chitsva cheWiFi 6 ndeaya:
Kuenzaniswa nechizvarwa chekare che802.11ac WiFi 5, iyo yakanyanya kutapurirana chiyero cheWiFi 6 yakawedzera kubva ku3.5Gbps yekutanga kusvika 9.6Gbps, uye iyo theoretical yekumhanyisa yakawedzera kanenge ka3.
Panyaya yemabhendi e frequency, WiFi 5 inongosanganisira 5GHz, nepo WiFi 6 ichivhara 2.4/5GHz, ichivhara zvakaderera-kumhanya uye yakakwirira-kumhanya michina.
Panyaya yemodulation mode, WiFi 6 inotsigira 1024-QAM, iyo yakakwirira kupfuura 256-QAM yeWiFi 5, uye ine yakakwirira data data, zvinoreva yakakwirira yekumhanyisa data.
Lower latency
WiFi 6 haisi kungowedzera kurodha nekudhawunirodha mitengo, asi zvakare kuvandudza kwakakosha mukusangana kwetiweki, kubvumidza mamwe madivayiri kuti abatanidze kune isina waya network uye kuve neinopindirana yakakwirira-kumhanya yekubatanidza ruzivo, iyo inonyanya kukonzerwa neMU- MIMO. uye OFDMA matekinoroji matsva.
Iyo WiFi 5 yakajairwa inotsigira MU-MIMO (yakawanda-mushandisi akawanda-inopinza akawanda-yakabuda) tekinoroji, inongotsigira downlink, uye inogona chete kuona tekinoroji iyi pakurodha zvirimo.WiFi 6 inotsigira zvese kumusoro uye downlink MU-MIMO, zvinoreva kuti MU-MIMO inogona kuwanikwa kana ichirodha uye kurodha data pakati penhare mbozha uye isina waya ma routers, zvichienderera mberi nekuvandudza kushandiswa kwebandwidth kwemawireless network.
Huwandu hwehuwandu hwenzvimbo dzedhata nzizi dzinotsigirwa neWiFi 6 dzakawedzerwa kubva pa4 muWiFi 5 kusvika 8, ndiko kuti, dzinogona kutsigira huwandu hwe8 × 8 MU-MIMO, chinova chimwe chezvikonzero zvakakosha zvekuwedzera kukuru chiyero cheWiFi 6.
WiFi 6 inoshandisa tekinoroji yeOFDMA (Orthogonal Frequency Division Multiple Access), inova shanduro yakagadziridzwa yeOFDM tekinoroji inoshandiswa muWiFi 5. Inosanganisa tekinoroji yeOFDM neFDMA.Mushure mekushandisa OFDM kushandura chiteshi kuita mutakuri wevabereki, vamwe vatakuri Tekinoroji yekutumira uye kutumira data inobvumira vashandisi vakasiyana kuti vagovane chiteshi chimwe chete, zvichibvumira mimwe michina kuti isvike, nenguva ipfupi yekupindura uye kunonoka kuderera.
Mukuwedzera, WiFi 6 inoshandisa iyo Yakareba DFDM Symbol transmission mechanism kuti iwedzere nguva yekufambisa yechiratidzo chega chega kubva ku3.2 μs muWiFi 5 kusvika ku12.8 μs, kuderedza chiyero chekurasikirwa kwepakeji uye chiyero chekudzorerazve, uye kuita kuti hutachiona huve hwakasimba.
Kukwanisa kukuru
WiFi 6 inosvitsa iyo BSS Coloring mashandiro, ichimaka mudziyo wega wega wakabatana kunetiweki, uye ichiwedzera anoenderana mavara kune yayo data panguva imwe chete.Kana uchitumira data, kune kero inoenderana, uye inogona kutumirwa zvakananga pasina kuvhiringidzika.
Multi-user MU-MIMO tekinoroji inobvumira akawanda materminal kugovera chiteshi chekombuta network nguva, kuitira kuti nharembozha/makomputa akawanda anogona kusefa paInternet panguva imwe chete.Yakasanganiswa neOFDMA tekinoroji, chiteshi chega chega pasi peWiFi 6 network inogona kuita yakakwira-inoshanda dhata, kuvandudza akawanda-mushandisi. kuomesa chando, uye huwandu hwacho hwakakura.
Safer
Kana mudziyo weWiFi 6 (wireless router) ichida kupihwa chitupa neWiFi Alliance, inofanirwa kutora WPA 3 kuchengetedza protocol, iyo yakachengeteka zvakanyanya.
Pakutanga kwa2018, iyo WiFi Alliance yakaburitsa chizvarwa chitsva cheWiFi encryption protocol WPA 3, iri vhezheni yakakwidziridzwa yeinonyanya kushandiswa WPA 2 protocol.Iko kuchengetedzeka kunowedzera kuvandudzwa, uye inogona kudzivirira zvirinani kurwiswa kwechisimba kwechisimba uye brute force kupaza.
kuwedzera simba rekuchengetedza
WiFi 6 inosvitsa tekinoroji yeTARget Wake Time (TWT), iyo inobvumira kuronga kwakasimba kwekutaurirana nguva pakati pemidziyo newireless routers, kuderedza kushandiswa kwewireless network antennas uye chiratidzo chekutsvaga nguva, iyo inogona kuderedza kushandiswa kwesimba kusvika pamwero wakati uye kugadzirisa bhatiri remudziyo. hupenyu.
HUANET inopa WIFI 6 ONT, kana uchiifarira, pls taura nesu.
