1. Nzira yekuchengetedza network
Munetwork dzisina waya, kukosha kwekuchengetedzwa kwenetwork hakufanirwe kunyanyosimbiswa. Wifi inetwork isina waya inobvumira michina yakawanda nevashandisi kubatana neInternet kuburikidza nenzvimbo imwe chete yekupinda. Wifi inowanzoshandiswawo munzvimbo dzeveruzhinji, uko kunenge kusina simba rekutonga kuti ndiani anogona kubatana nenetwork. Muzvivakwa zvemakambani, ruzivo rwakakosha runofanira kuchengetedzwa kana ma hackers ane hukasha akaedza kuparadza kana kuba data.
Wifi 5 inotsigira maprotocol eWPA neWPA2 ekubatanidza kwakachengeteka. Aya ndiwo magadzirirwo akakosha ekuchengetedza kupfuura maprotocol eWEP asisina kushanda, asi ikozvino ane akawanda matambudziko uye kusasimba. Chimwe chezvinetso zvakadaro kurwiswa kweduramazwi, uko matsotsi epaindaneti anogona kufanotaura password yako yakavharidzirwa nekuyedza kakawanda uye kusanganisa.
Wifi 6 ine protocol yemazuva ano yekuchengetedza WPA3. Saka, zvishandiso zvinotsigira Wifi 6 zvinoshandisa maprotocol eWPA, WPA2, uye WPA3 panguva imwe chete. Wifi Protected Access 3 Maitiro ekuvandudza ekusimbisa uye encryption ane zvinhu zvakawanda. Ine tekinoroji yeOWE inodzivirira automatic encryption, uye pakupedzisira, makodhi eOR anoskenwa anobatanidzwa zvakananga kune mudziyo.
2. Kumhanya kwekutumira data
Kumhanya chinhu chakakosha uye chinonakidza icho matekinoroji matsva anofanira kugadzirisa asati aburitswa. Kumhanya kwakakosha kune zvese zvinoitika paInternet uye chero rudzi rwenetwork. Mitengo inokurumidza zvinoreva nguva pfupi yekurodha, kutenderera zviri nani, kutamisa data nekukurumidza, kuonana kwevhidhiyo nezwi zviri nani, kubhurawuza nekukurumidza nezvimwewo.
Wifi 5 ine kumhanya kwepamusoro kwekutapurirana data kwe6.9 Gbps. Muhupenyu chaihwo, avhareji yekumhanya kwekutapurirana data kwe802.11ac standard inenge 200Mbps. Kumhanya kunoshanda kweWifi standard kunoenderana neQAM (quadrature amplitude modulation) uye huwandu hwemidziyo yakabatana ne access point kana router. Wifi 5 inoshandisa 256-QAM modulation, yakaderera zvikuru pane Wifi 6. Pamusoro pezvo, tekinoroji yeWifi 5 MU-MIMO inobvumira kubatana panguva imwe chete kwemidziyo mina. Midziyo yakawanda inoreva kuzara uye kugovana bandwidth, zvichikonzera kumhanya kunononoka kwemudziyo wega wega.
Kusiyana neizvi, Wifi 6 isarudzo iri nani kana tichitarisa kumhanya, kunyanya kana network yakazara. Inoshandisa 1024-QAM modulation kuti ikwanise kutumirwa data kusvika ku9.6Gbps. Wi-fi 5 uye wi-fi 6 speeds hazvisiyane zvakanyanya kubva pamudziyo kuenda kune mumwe. Wifi 6 inogara ichikurumidza, asi mukana wekumhanya ndewekuti michina yakawanda yakabatana neWifi network. Huwandu chaihwo hwemidziyo yakabatana inokonzera kudzikira kukuru kwekumhanya uye simba reInternet remidziyo yeWifi 5 nemarouters pakushandisa Wifi 6 hauzomboonekwi.
3. Nzira yekugadzira danda
Kugadzira danda inzira yekutumira masaini inotungamira chiratidzo chisina waya kune chinogamuchira, pane kuparadzira chiratidzo kubva kune imwe nzira. Uchishandisa beamforming, nzvimbo yekupinda inogona kutumira data zvakananga kuchishandiso pane kuparadzira chiratidzo kumativi ese. Kugadzira danda haisi tekinoroji itsva uye ine maapplication muWifi 4 neWifi 5. MuWifi 5 standard, maantenna mana chete ndiwo anoshandiswa. Wifi 6, zvisinei, inoshandisa maantenna masere. Kana Wifi router ikashandisa tekinoroji yekugadzira danda zviri nani, chiyero chedata uye huwandu hwechiratidzo zvinovandudzika.
4. Orthogonal Frequency Division Multiple Access (OFDMA)
Wifi 5 inoshandisa tekinoroji inonzi orthogonal frequency division multiplexing (OFDM) yekudzora kupinda kwenetwork. Iyi inzira yekudzora huwandu hwevashandisi vanopinda subcarrier panguva yakatarwa. Mu 802.11ac standard, mabhendi e20mhz, 40mhz, 80mhz uye 160mhz ane ma subcarriers makumi matanhatu nemana, ma subcarriers zana nemakumi maviri nemasere, ma subcarriers mazana maviri nemakumi mashanu nematanhatu uye ma subcarriers mazana mashanu negumi nemaviri zvichiteerana. Izvi zvinoderedza zvakanyanya huwandu hwevashandisi vanogona kubatana nekushandisa network yeWifi panguva yakatarwa.
Kune rumwe rutivi, Wifi 6 inoshandisa OFDMA (orthogonal frequency division multiple access). Tekinoroji yeOFDMA inowedzera nzvimbo iripo ye subcarrier mubhendi rimwe chete re frequency. Nekuita izvi, vashandisi havafanirwe kumirira mumutsara kuti vawane sub-carrier yemahara, asi vanogona kuiwana zviri nyore.
OFDMA inopa mayuniti akasiyana ezvishandiso kune vashandisi vakawanda. OFDMA inoda ma subcarriers akapetwa kana kupfuura matekinoroji ekare pane matekinoroji ekare. Izvi zvinoreva kuti mumachaneli e20mhz, 40mhz, 80mhz, uye 160mhz, standard ye802.11ax ine ma subcarriers 256, 512, 1024, uye 2048 zvichiteerana. Izvi zvinoderedza kuzara uye kunonoka, kunyangwe kana uchibatanidza zvishandiso zvakawanda. OFDMA inovandudza kushanda zvakanaka uye inoderedza kunonoka, zvichiita kuti ive yakakodzera mashandiro ebandwidth yakaderera.
5. Kupinza Zvakawanda Kwevashandisi Vazhinji (MU-MIMO)
MU MIMO zvinoreva kuti "multiple user, multiple input, multiple output". Iyi itekinoroji isina waya inobvumira vashandisi vakawanda kutaurirana nerouter panguva imwe chete. Kubva paWifi 5 kusvika kuWifi 6, kugona kweMU MIMO kwakasiyana zvikuru.
Wifi 5 inoshandisa downlink, nzira imwe chete 4×4 MU-MIMO. Izvi zvinoreva kuti vashandisi vakawanda vane zvipingamupinyi zvakananga vanogona kuwana router uye Wifi connection yakagadzikana. Kana muganho wekutumira ma "transmissions" mana panguva imwe chete wapfuura, Wifi inotanga kuzara uye inotanga kuratidza zviratidzo zvekuzara, zvakaita sekunonoka kwakanyanya, kurasikirwa nemapaketi, nezvimwewo.
Wifi 6 inoshandisa tekinoroji ye8×8 MU MIMO. Izvi zvinogona kubata midziyo inosvika 8 yakabatana uye kushandiswa kweWireless LAN pasina kukanganiswa. Zviri nani, Wifi 6 MU MIMO inovandudzwa nemativi maviri, zvichireva kuti peripherals inogona kubatana nerouter pane ma frequency band akawanda. Izvi zvinoreva kugona kuri nani kuisa ruzivo paInternet, pakati pezvimwe zvinoshandiswa.
6. Mabhendi eFrequency
Musiyano mumwe chete uri pachena pakati peWifi 5 neWifi 6 ndewemabhendi emafrequency ematekinoroji maviri aya. Wifi 5 inoshandisa bhendi re5GHz chete uye haina kupindirana kwakawanda. Dambudziko nderekuti masaini emagetsi mapfupi uye kugona kupinda mumadziro nezvimwe zvipingamupinyi kwakaderera.
Wifi 6, kune rumwe rutivi, inoshandisa ma frequency maviri ebhendi, iyo yakajairika ye2.4Ghz ne5Ghz. MuWifi 6e, vagadziri vachawedzera bhendi re6ghz kumhuri yeWifi 6. Wifi 6 inoshandisa mabhendi ese ari maviri e2.4Ghz ne5Ghz, zvinoreva kuti zvishandiso zvinogona kuskena nekushandisa bhendi iyi otomatiki pasina kupindira kwakanyanya uye kushanda kuri nani. Nenzira iyi, vashandisi vanowana zvakanakisa kune ese ma network, nekumhanya nekukurumidza padyo uye padanho rakakura kana peripherals dzisiri panzvimbo imwe chete.
7. Kuwanikwa kwemavara eBSS
Kupenda BSS chimwe chinhu chiri muWifi 6 chinoisiyanisa nezvizvarwa zvakapfuura. Ichi chinhu chitsva cheWifi 6 standard. BSS, kana kuti seti yekubatsira, pachayo chinhu chinowanikwa mune network yega yega ye802.11. Zvisinei, Wifi 6 chete nezvizvarwa zvinotevera ndizvo zvichakwanisa kunzwisisa mavara eBSS kubva kune mamwe maturusi vachishandisa BSS color identifiers. Chinhu ichi chakakosha nekuti chinobatsira kudzivirira masaini kuti asapindirane.
8. Musiyano wenguva yekufukidzwa
Kunonoka kunoreva kunonoka kwekutumirwa kwemapaketi kubva panzvimbo imwe kuenda kune imwe. Kunonoka kushoma kuri pedyo ne zero ndiko kwakanyanya kunaka, zvichiratidza kunonoka kushoma kana kusanonoka zvachose. Kana tichienzanisa ne Wifi 5, Wifi 6 ine kunonoka kupfupi, zvichiita kuti ive yakakodzera mabhizinesi nemasangano emabhizinesi. Vashandisi vepamba vachadawo chinhu ichi pama Wifi models matsva, sezvo zvichireva kukurumidza kupinda.kubatana kweinternet.
