802.11A / B / G / G / N / AC Budiriro uye Kusiyanisa

802.11A / B / G / G / N / AC Budiriro uye Kusiyanisa
Sezvo kusunungurwa kwekutanga kweWI Fi kune vatengi muna 1997, iyo WI Chiyero chave chiri kugara uchisimuka, kazhinji zvinowedzera kumhanya uye kuwedzera kufukidzwa. Sezvo mabasa akawedzerwa kune yekutanga ieee 802.11 standard, ivo vakadzokororwa kuburikidza nekugadzirisa kwayo (802.11B, 802.11g, nezvimwewo)

802.11B
802.11B inoshandisa zvakafanana 2.4 ghz frequency seyekutanga 802.11 standard. Iyo inotsigira yakanyanya kuwanda kwekumhanya kwegumi nemamps uye huwandu hwemamita kusvika zana nemashanu. 802.11B zvikamu zvakachipa, asi iyi chiyero chine kumhanya kwakanyanya uye kunonoka kumhanya pakati peese 802.11 zviyero. Uye nekuda kwe802.11B inoshanda pa2,4 ghz, yemidziyo yemisha kana imwe 2.4 ghz wi fi fi networks inogona kukonzera kupindira.

802.11A 5GHZ
Shanduro yakagadziridzwa "A" yeichi chiyero chinoburitswa panguva imwe chete ne802.11b. Inosvitsa tekinoroji yakaomesesa inonzi yeForm (Orthogonal Frequency Kugovaniswa kuwanda) yekugadzira saina isina waya. 802.11A inopa zvimwe zvakanakira kupfuura 802.11B: Inoshanda mune yakaisvonaka manhukwana mashanu GHZ frequency bhendi uye saka isinganyanye kutakurwa nekukanganisa. Uye bandwidth yayo yakakwira kupfuura 802.11b, ine theonetical yakakwira ye5 Mbps.
Iwe unogona kunge usina kusangana nevakawanda 802.11A midziyo kana maRouters. Izvi zvinodaro nekuti 802.11B midziyo yakachipa uye kuve nekuwedzera kufarirwa mumusika wevatengi. 802.11A inonyanya kushandiswa kune bhizinesi zvikumbiro.

802.11G 2.4GHZ OFDM
Iyo 802.11g standard inoshandisa iyo yakafanana yeiyo yeForm tekinoroji se802.11A. Sa 802.11A, inotsigira huwandu hwakanyanya hwezvirevo zve54 MBPS. Nekudaro, kunge 802.11B, inoshanda mune yakasungwa 2.4 ghz frequency 802.11G irikudzokera shure ne802.11b access: 802.1b zvishandiso zvinogona kubatanidza kusvika 802.11g yekuwana mapoinzi (asi pa802.1b inomoka).
Na802.11g, vatengi vakaita zvakakura kufambira mberi muWI FI SEPRINE uye kufukidza. Zvichakadaro, tichienzanisa nezvizvarwa zvakapfuura zvezvigadzirwa, vatengi vasina waya vasina ma routers vari kuva nani uye zviri nani, vane simba repamusoro uye nekuvhara kuri nani.

802.11n (WI Fi 4) 2.4 / 5GHZ Mimo
Ne802.11n standard, wi fi inokurumidza uye yakavimbika. Iyo inotsigira yakanyanya kuwanda kwekutapurirana kwe 300 Mbps (kusvika 450 mbps kana uchishandisa matatu antennas). 802.11n inoshandisa mimo (yakawanda yekuisa akawanda kubuda), uko akawanda transmitters / anogamuchira anoshanda panguva imwe chete kana maviri emigumo yechibatanidza. Izvi zvinogona kuwedzera zvakanyanya data pasina inoda yakakwira bandwidth kana simba resimba. 802.11n inogona kushanda muna 2.4 GHz uye 5 GHZ Frequency.

802.11Ac (Wi Fi 5) 5GHZ Mu-Mimo
802.11ac inowedzera wi fi fi, ine mhanya kubva pamakumi mana nemakumi mana emambhiti kune akati wandei gigabits pane yechipiri. Kuti uwane izvi kuita, 802.11ac inoshanda chete mu 5 ghz frequency bhendi, inotsigira kusvika kune spatial svutuzi ye802 Nesimba, antennas inogona kutapurirana neye masaini yeredhiyo, saka vanonongedza zvakananga kumidziyo chaiyo.

Chimwezve kufambira mberi kwe802.11ac imushandisi Multi (mu-mimo). Kunyangwe Mimo anotungamira akawanda hova kune mumwe mutengi, mu-mimo anogona panguva imwe chete zvakananga nehuremu hwemahara kune vatengi vakawanda. Kunyangwe mu-mimo haawedzere kumhanya kwemutengi chero munhu mumwe nemumwe, inogona kuvandudza iyo yakazara data yekupfuura yekoneti yese.
Sezvauri kuona, Wi fi yekuita inoenderera mberi kusimuka, nekugona kunyemwerera uye kuita kwekuita kusvika pakumhanya

802.11Ax WI Fi 6
Muna 2018, mubatanidzwa weWiFi wakatora matanho ekuita kuti wifi mabvumirano ave nyore kuziva uye kunzwisisa. Ivo vachachinja iyo inotevera 802.11Ax Standard kusvika Wifi6

Wi fi 6, iripi 6?
Iyo yakati wandei performance zviratidzo zveWI inosanganisira kutumira kure, kutapurirana chiyero, network kugona, uye hupenyu hwebhatiri. Nekuvandudzwa kwe tekinoroji uye nguva, zvinodiwa nevanhu zvekumhanya uye bandwidth zvave kuwedzera kukwirira.
Kune nhevedzano yematanho mune yechinyakare yeWI kusawirirana, yakadai seyineti yekubatanidza, kufukidzwa kudiki, uye kudiwa kwekugara uchinja ssids.
Asi wi 6 ichaunza shanduko nyowani: Inowedzera mashandiro emidziyo uye inovhara mari yemushandisi yakakwira, uye inogona kuunza zvakare marefu ekuendesa marefu uye yakakwirira kutapurirana.
Zvakawanda, zvichienzaniswa nevaratidziro wayo, mukana weWI FI 6 "DALOLOLWN uye DUAL LOOD":
Kumhanyisa kukwira: Kutenda kuNhamba yeTeckLologies yakadai sekukwidza mu-mimo, 1024QUM
Kuwanika Kwakakura: Iyo Yakanyanya Kukosha Kuvandudzwa kweWI FI 6 ndeye kuderedza kuwiriranisa uye bvumira midziyo yakawanda yekubatanidza kune network. Parizvino, WI Fi 5 inogona kutaurirana nezvinhu zvina panguva imwe chete panguva imwe chete, nepo wi 6 ichabvumira kutaurirana nekwavo kune akawanda mashiripi panguva imwe chete. WI FI 6 zvakare inoshandisa yeDDMA (Orthogonal Frequency-Desisionl Kuwanika Kwekuwana) uye Multi-Channel Signal Signal Inction
Low LATENCY: Nekushandisa matekinoroji akadai saForma uye Spatialreuse, anogonesa vashandisi vakafanana mukati menguva yega yega, kubvisa kudiwa, kuderedza kugona, nekuvandudza kushanda, uye kuderedza latency. Kubva pamakumi matatu emams ewi mashanu kusvika makumi maviri, neavhareji latency kuderedzwa kwe33%.
Yepasi Simba Kushandisa: Twt, imwe tekinoroji idzva muWI Fi 6, inobvumira AP kuti utaure kutaurirana nezviratidziro, kuderedza nguva inodiwa kuti urambe uchichengetedza uye kutsvaga masaini. Izvi zvinoreva kuderedza kushandiswa kwebhatiri uye kuvandudza hupenyu hwebhatiri, zvichikonzera kuderedzwa kwemakumi matatu muzana mukushandiswa kwesimba.
