Zvichienzaniswa nezvizvarwa zvekare zveWiFi tekinoroji, zvinhu zvikuru zvechizvarwa chitsva cheWiFi 6 ndeizvi:
Zvichienzaniswa nechizvarwa chekare che802.11ac WiFi 5, huwandu hwepamusoro hwekutapurirana kweWiFi 6 hwakawedzerwa kubva pa3.5Gbps yepakutanga kusvika pa9.6Gbps, uye kumhanya kwedzidziso kwakawedzera kanenge katatu.
Panyaya yemabhendi emafrequency, WiFi 5 inongoshanda pa5GHz chete, nepo WiFi 6 ichishanda pa2.4/5GHz, ichishanda zvizere pamidziyo inomhanya zvishoma uye inomhanya zvakanyanya.
Panyaya ye modulation mode, WiFi 6 inotsigira 1024-QAM, iyo iri pamusoro pe256-QAM yeWiFi 5, uye ine data rakawanda, zvinoreva kuti data rinokurumidza kutumirwa.
Kunonoka kwakaderera
WiFi 6 haisi kungowedzera huwandu hwekurodha nekudhawunirodha chete, asiwo iri nani pakuzara kwenetwork, zvichibvumira michina yakawanda kubatana nenetwork isina waya uye kuva neruzivo rwekubatana nekukurumidza nguva dzose, izvo zvinonyanya kukonzerwa netekinoroji itsva dzeMU-MIMO neOFDMA.
WiFi 5 standard inotsigira tekinoroji yeMU-MIMO (multi-user multi-input multiple-output), iyo inotsigira downlink chete, uye inogona chete kuona tekinoroji iyi kana ichidhawunirodha zviri mukati. WiFi 6 inotsigira uplink ne downlink MU-MIMO, zvinoreva kuti MU-MIMO inogona kuonekwa kana uchidhawunirodha uye uchidhawunirodha data pakati pemafoni nema routers asina waya, zvichiwedzera kuvandudza kushandiswa kwebandwidth kwema network asina waya.
Huwandu hwepamusoro hwenzvimbo dzinoshandiswa neWiFi 6 hwakawedzerwa kubva pa4 muWiFi 5 kusvika pa8, kureva kuti, inogona kutsigira huwandu hwe8×8 MU-MIMO, inova imwe yezvikonzero zvakakosha zvekuwedzera kukuru kwehuwandu hweWiFi 6.
WiFi 6 inoshandisa tekinoroji yeOFDMA (Orthogonal Frequency Division Multiple Access), inova vhezheni yakavandudzwa yetekinoroji yeOFDM inoshandiswa muWiFi 5. Inosanganisa tekinoroji yeOFDM neFDMA. Mushure mekushandisa OFDM kushandura chiteshi kuita chiteshi chikuru, mamwe ma subcarriers Tekinoroji yekutumira data inobvumidza vashandisi vakasiyana kugovera chiteshi chimwe chete, zvichibvumira michina yakawanda kupinda, nenguva pfupi yekupindura uye kunonoka kushoma.
Pamusoro pezvo, WiFi 6 inoshandisa nzira yekutumira yeLong DFDM Symbol kuwedzera nguva yekutumira yemutakuri wega wega wechiratidzo kubva pa3.2 μs muWiFi 5 kusvika pa12.8 μs, zvichideredza mwero wekurasikirwa kwepaketi uye mwero wekutumirazve, uye zvichiita kuti kutumira kuve kwakasimba.
Kukwanisa kukuru
WiFi 6 inoisa nzira yeBSS Coloring, ichimaka mudziyo wega wega wakabatana netiweki, uye ichiisa mavara anoenderana nedata rayo panguva imwe chete. Pakutumira data, pane kero inoenderana, uye inogona kutumirwa zvakananga pasina kuvhiringidzika.
Tekinoroji yeMU-MIMO inoshandiswa nevashandisi vakawanda inobvumira materminal akawanda kugovana chiteshi chenguva yenetwork yekombuta, kuitira kuti nharembozha/makombiyuta akawanda agone kushandisa internet panguva imwe chete. Pamwe chete netekinoroji yeOFDMA, chiteshi chimwe nechimwe chiri pasi peWiFi 6 network chinogona kutumira data nekukurumidza, zvichivandudza vashandisi vakawanda. Ruzivo rwenetwork munzvimbo iyi runogona kusangana zviri nani nezvinodiwa nenzvimbo dzeWiFi hotspot, kushandiswa kwevashandisi vakawanda, uye hazvisi nyore kuomesa, uye kugona kwayo kwakakura.
Zvakachengeteka
Kana mudziyo weWiFi 6 (wireless router) uchida kusimbiswa neWiFi Alliance, unofanirwa kushandisa WPA 3 security protocol, iyo yakachengeteka zvakanyanya.
Pakutanga kwa2018, WiFi Alliance yakaburitsa chizvarwa chitsva cheWiFi encryption protocol WPA 3, inova vhezheni yakagadziridzwa yeprotocol inoshandiswa zvakanyanya yeWPA 2. Kuchengetedzwa kuri kuvandudzwa, uye kunogona kudzivirira zviri nani kurwiswa kwebrute force uye brute force cracking.
kuchengetedza simba zvakanyanya
WiFi 6 inoburitsa tekinoroji yeTARget Wake Time (TWT), iyo inobvumira kuronga nguva yekutaurirana pakati pemidziyo nemarouter asina waya, zvichideredza kushandiswa kwemaantenna enetwork asina waya uye nguva yekutsvaga masaini, izvo zvinogona kuderedza kushandiswa kwesimba kusvika pamwero wakati uye kuvandudza hupenyu hwebhatiri remuchina.
HUANET inopa WIFI 6 ONT, kana uchifarira, ndapota taura nesu.
