Molemo oa WIFI 6 ONT

Ha ho bapisoa le meloko e fetileng ea theknoloji ea WiFi, likarolo tsa mantlha tsa moloko o mocha oa WiFi 6 ke:
Ha ho bapisoa le moloko o fetileng oa 802.11ac WiFi 5, lebelo le phahameng la phetisetso ea WiFi 6 le eketsehile ho tloha ho 3.5Gbps ea pele ho ea ho 9.6Gbps, 'me lebelo la theory le eketsehile ka makhetlo a ka bang 3.
Mabapi le lihlopha tsa maqhubu, WiFi 5 e kenyelletsa 5GHz feela, ha WiFi 6 e koahela 2.4 / 5GHz, e koahelang ka botlalo lisebelisoa tse tlaase le tse phahameng.
Mabapi le mokhoa oa ho feto-fetoha, WiFi 6 e ts'ehetsa 1024-QAM, e phahameng ho feta 256-QAM ea WiFi 5, 'me e na le matla a phahameng a data, e bolelang lebelo le phahameng la phetisetso ea data.

Ho lieha ho tlase
WiFi 6 ha se feela keketseho ea litefiso tsa ho kenya le ho jarolla, empa hape ke ntlafatso e kholo ea tšubuhlellano ea marang-rang, e lumellang lisebelisoa tse ngata ho hokela marang-rang a se nang mohala le ho ba le boiphihlelo bo sa fetoheng ba khokahano ea lebelo le phahameng, e hlahisoang haholo ke MU- MIMO. le OFDMA theknoloji e ncha.
Tekanyetso ea WiFi 5 e ts'ehetsa tekhenoloji ea MU-MIMO (ea basebelisi ba bangata ba li-input multiple-output), e ts'ehetsang li-downlink feela, 'me e khona ho fumana theknoloji ena ha e khoasolla litaba.WiFi 6 e ts'ehetsa uplink le downlink MU-MIMO, ho bolelang hore MU-MIMO e ka ba le boiphihlelo ha e kenya le ho khoasolla data lipakeng tsa lisebelisoa tsa mohala le li-routers tse se nang mohala, ho ntlafatsa ts'ebeliso ea marang-rang ea marang-rang a se nang mohala.
Palo e kholo ea melapo ea data ea sebaka e tšehelitsoeng ke WiFi 6 e eketsehile ho tloha ho 4 ho WiFi 5 ho isa ho 8, ke hore, e ka ts'ehetsa boholo ba 8 × 8 MU-MIMO, e leng le leng la mabaka a bohlokoa a keketseho e kholo ea lebelo la WiFi 6.
WiFi 6 e sebelisa theknoloji ea OFDMA (Orthogonal Frequency Division Multiple Access), e leng mofuta o ntlafalitsoeng oa theknoloji ea OFDM e sebelisoang ho WiFi 5. E kopanya theknoloji ea OFDM le FDMA.Ka mor'a ho sebelisa OFDM ho fetola mocha hore e be mochine oa motsoali, ba bang ba li-subcarriers Theknoloji ea phetisetso ea ho kenya le ho fetisa data e lumella basebelisi ba fapaneng ho arolelana mocha o le mong, ho lumella lisebelisoa tse ngata ho fihlella, ka nako e khutšoanyane ea karabo le ho lieha ho fokolang.

Ho phaella moo, WiFi 6 e sebelisa mokhoa oa nako e telele oa phetisetso ea Letšoao la DFDM ho eketsa nako ea phetisetso ea mochine o mong le o mong oa matšoao ho tloha ho 3.2 μs ho WiFi 5 ho ea ho 12.8 μs, ho fokotsa sekhahla sa tahlehelo ea pakete le tekanyo ea phetisetso, le ho etsa hore phetiso e be e tsitsitseng haholoanyane.

Matla a maholo
WiFi 6 e hlahisa mochini oa BSS Coloring, e tšoaea sesebelisoa se seng le se seng se hokahaneng le marang-rang, 'me e eketsa lileibole tse tsamaellanang ho data ea eona ka nako e le ngoe.Ha o fetisetsa data, ho na le aterese e lumellanang, 'me e ka fetisoa ka ho toba ntle le pherekano.

Theknoloji ea MU-MIMO ea basebelisi ba bangata e lumella li-terminals tse ngata ho arolelana mocha oa nako ea marang-rang a khomphutha, e le hore lifono/lik'homphieutha tse ngata li khone ho kena Inthaneteng ka nako e le 'ngoe.E kopantsoe le theknoloji ea OFDMA, mocha o mong le o mong tlas'a marang-rang a WiFi 6 o ka etsa phetiso ea data e phahameng ka ho fetisisa, ea ntlafatsa basebelisi ba bangata Boiphihlelo ba marang-rang sebakeng sena bo ka finyella litlhoko tsa libaka tsa WiFi hotspot, tšebeliso ea basebelisi ba bangata, 'me ha ho bonolo. ho hoama, mme matla a maholo.

E sireletsehileng haholoanyane
Haeba sesebelisoa sa WiFi 6 (router e se nang mohala) se hloka ho netefatsoa ke WiFi Alliance, se tlameha ho amohela protocol ea ts'ireletso ea WPA 3, e sireletsehileng haholoanyane.
Mathoasong a 2018, WiFi Alliance e lokolotse moloko o mocha oa protocol ea encryption ea WiFi WPA 3, e leng mofuta o ntlafalitsoeng oa protocol e sebelisoang haholo ea WPA 2.Tšireletso e ntlafatsoa le ho feta, 'me e ka thibela litlhaselo tsa brute force le ho qhekella ha brute force.
ho boloka matla ho feta
WiFi 6 e hlahisa theknoloji ea TARget Wake Time (TWT), e lumellang moralo o sebetsang oa nako ea puisano pakeng tsa lisebelisoa le li-routers tse se nang mohala, ho fokotsa tšebeliso ea li-antenna tsa marang-rang tse se nang mohala le nako ea ho batla matšoao, e ka fokotsang tšebeliso ea matla ho isa tekanyong e itseng le ho ntlafatsa betri ea mochine. bophelo.

HUANET fana ka WIFI 6 ONT, haeba u e thahasella, pls ikopanye le rona.
