802.11ac ndiyo inowirirana ye Wi-Fi wireless networking yakanyanya kupfuura yezera rekare ra 802.11n . Kuverenga shure kwechechina-inozivikanwa yepakutanga ye 802.11 yakatsanangurwa kumashure muna 1997, 802.11ac inomiririra chizvarwa che5 che Wi-Fi teknolojia. Zvichienzaniswa ne802.11n uye vakatarisa vayo, 802.11ac inopa zviri nani network network uye inokwanisa kushandiswa kuburikidza nehupfumi hukuru hwepamusoro uye firmware device.
Nhoroondo ye 802.11ac
Chirongwa chekugadzira 802.11ac chakatanga muna 2011. Kunyange zvazvo mutemo wacho wakagadzirirwa pakupera kwegore ra2013 uye zvakagamuchirwa zvakajeka musi waJanuary 7, 2014, vatengi zvigadzirwa zvakabva pane zvinyorwa zvekare zvakasununguka zvakaonekwa kare.
802.11ac Technical Technical Specifications
Kuti uwane makwikwi mubhizimusi uye rubatsiro rwunowanzowedzera kushandiswa sevhidhiyo inopararira inoda kuwanda kwehutano hwekutengesa, 802.11ac yakagadzirirwa kuita zvakafanana neGigabit Ethernet . Zvechokwadi, 802.11ac inopa inoretical data rates kusvika 1 Gbps . Inoita izvi kuburikidza nekubatanidzwa kwekusaita kusina kushandiswa kwekujekesa, kunyanya:
- michina inoshandisa nzvimbo yakakura (yakafara) yevhenekeri mahara, uye
- nhamba yakawanda yeMIMO radios uye antennas kuti zvibvumirwe kuparidzira pamwe chete
802.11ac inoshanda mu 5 GHz reta rezera kusiyana nemadzinza akapfuura eWi-Fi akashandiswa 2.4 gHz chiteshi. Vagadziri ve 802.11ac vakaita sarudzo iyi nekuda kwezvikonzero zviviri:
- kudzivisa nyaya dzekusanganisa kusina mhepo dzisina kufanana ne 2.4 GHz semamwe marudzi mazhinji emagetsi emashandisi anoshandisa maitiro akafanana (nekuda kwehutungamiri huri kuronga hurumende)
- kuti iite zviratidzo zvakakura zvakajeka (sezvataurwa pamusoro) kupfuura nzvimbo 2.4 GHz inonyatsobvumidza
Kuti uchengetedze kushamwaridzana shure nehukuru hweWi-Fi michina, 802.11ac wireless network routers inosanganisirawo zvakasiyana 802.11n-style 2.4 GHz protocol kutsigirwa.
Chimwe chinhu chitsva che 802.11ac chinonzi beamforming chakagadzirirwa kuwedzera kuvimbika kwehutano hweWi-Fi mune dzimwe nzvimbo dzakawanda. Beamforming teknolojia inobatsira ma-radios kuti atarise zviratidzo zvavo mune imwe nzira yekugamuchira antenna pane kuparadzira chiratidzo kune 180 kana 360 degrees semavhidhiyo emagariro.
Beamforming imwe yemhando yezvinhu zvakasarudzwa neyero ye 802.11ac sechinhu chakanaka, pamwe chete nemakiromita emagetsi maviri akaenzana (160 MHz pane 80 MHz) nezvimwe zvinhu zvakawanda zvakanyanyisa.
Matambudziko ane 802.11ac
Vamwe vatsvakurudzi nevatengi vave vasina chokwadi neicho chaicho-nyika inobatsira 802.11ac inounza. Vashandi vakawanda havana kungovandudza mishonga yavo kubva kumusha kubva ku802.11g kusvika ku 802.11n, somuenzaniso, sezvo mutemo wekare unowanzosangana nezvinhu zvinodiwa. Kuti unakidzwe nehutano hunobudirira uye hutano hwakakwana 802.11ac, zvigadzirwa pamativi ose maviri ehutano zvinofanira kusimbisa mutemo mutsva. Kunyange zvazvo mairaira 802.11ac akapinda mumusika nekukurumidzira , chikwata chinokwana 802.11ac chakatora nguva yakareba kuti chiwane nzira yekuenda kumashoni emafoni uye mapepa, semuenzaniso.
