Saib cov kev ua tau zoo thiab cov kev txwv ntawm kev siv ob zaug ntawm Wi-Fi
Wi-nkaus tes hauj lwm siv xov tooj cua cov teeb tseg hauv lub 2.4 GHz los yog 5 GHz zaus qeeb. Cov xov tooj no yog tshaj tawm txog cov khoom ntim, tab sis lawv lub ntsiab lus yog to taub ntau.
Tag nrho cov niaj hnub Wi-nkaus li kev txhawb nqa 2.4 HLz kev sib txuas, thaum qee cov khoom txhawb nqa ob leeg. Tsev broadband routers uas feature 2.4 GHz thiab 5 GHz radios hu ua dual-band routers.
Ib qho tseem ceeb uas yuav ua tau yog nruab nrab ntawm lub Nruab Nrab WiFi thiab koj lub xov tooj txawb wireless network. Cov no yog ob hom kev sib txawv heev, thiab nws muaj peev xwm ua tau ntau tshaj qhov qub tshaj yog thaum koj tham txog 5 GHz WiFi zaus band thiab 5G mobile networking tshuab, hloov rau 4G .
Ntawm no peb yuav tham txog WiFi kev sib txuas lus uas koj tuaj yeem tsim hauv koj lub tsev uas yog siv lub router, thiab ob qhov chaw siv tsawg thiab siv cov hlua khi ob lub nplhaib coj los siv kom zoo tshaj plaws ntawm ob qho tib si. Qhov no tsis npog txawb hluav taws xob tshuab rau smartphones thiab lwm yam khoom siv.
GHz thiab Network ceev
WiFi networking tuaj nyob rau hauv ob peb ntau yam. Cov kev cai hauv WiFi txhais cov kev txhim kho hauv kev siv technology. Cov txheej txheem yog (raws li kev tso tawm, qhov qub tshaj plaws kom tshiab):
- 802.11a
- 802.11b
- 802.11g
- 802.11n
- 802.11ac
Cov qauv no txuas nrog rau GHz band frequencies, tab sis cov no tsis yog sib tham txog cov ncauj lus tseem ceeb nyob ntawm no, tab sis lawv raug xa mus rau.
Ib lub 5 GHz network yuav nqa cov ntaub ntawv ntau dua li ntawm 2.4 GHz network thiab yog li technically ceev (piv txwv tias lub hwj huam hluav taws xob rau lub xov tooj cua ntau dua yog tswj xyuas ntawm qib siab dua). 5GHz cov kev pabcuam xovtooj ntawm cov xovtooj hauv cov kev cai lij choj 802.11n thiab 802.11ac . Cov cuab yeej hauv tsev uas tsim los yog haus cov nqi ntau tshaj ntawm cov kev sib tshuam, xws li video streaming units lossis consoles consoles, feem ntau khiav ceev tshaj 5 GHz sib txuas.
GHz thiab Network ntau
Qhov ntau dua cov zaus ntawm lub teeb liab, nws qhov luv luv. 2.4 GHz wireless tes hauj lwm yog li ntawd npog ntau tshaj li ntawm 5 GHz tes hauj lwm. Hauv particular, Pib ntsais koj teeb ntawm 5 GHz frequencies tsis txeem cov khoom zoo li zoo li ua 2.4 GHz tseg, limiting lawv cuag hauv tsev.
GHz thiab Network Interference
Koj yuav pom tias qee cov xov tooj tsis muaj xov tooj, lub qhov rooj qhib qhov rooj qhib, thiab lwm cov khoom siv hauv vaj hauv tsev kuj siv 2.4 GHz signaling. Vim hais tias qhov sib txuam no feem ntau yog siv hauv cov khoom siv rau neeg siv khoom, nws tuaj yeem ua pa taws. Qhov no ua rau nws xav tias qhov 2.4 GHz tsev network yuav raug cuam tshuam los ntawm cov cuab yeej siv dua li ntawm 5 GHz hauv tsev network. Qhov no tuaj yeem ua kom qeeb thiab cuam tshuam WiFi network ceev hauv cov no.
GHz thiab cov nqi
Qee cov neeg yuam kev ntseeg tias 5 GHz network technology tshiab lossis ntau dua li ntawm 2.4 GHz vim 5 GHz cov tsev khiav haujlwm hauv tsev feem ntau pib muaj tom qab cov neeg siv 2.4 GHz radios. Qhov tseeb, ob hom kev kos npe tau muaj nyob rau ntau xyoo thiab yog ob qhov pov thawj ntawm kev pom tseeb.
Routers muaj ob 2.4GHz thiab 5GHz xov tooj cua feem ntau kim tshaj cov Self tsuas 2.4GHz radios.
Lub Kab Hauv Qab
5 GHz thiab 2.4 GHz yog sib txawv wireless signals frequencies uas txhua qhov zoo rau Wi-nkaus networking, thiab cov kev zoo yuav vam khom siab li cas koj teev koj lub network-tshwj xeeb tshaj yog thaum twg xav tias yuav deb npaum li cas thiab dhau ntawm obstructions koj lub teeb liab yuav tsum tau mus txog. Yog hais tias koj xav tau ntau yam thiab ntau ntawm nkag mus los ntawm phab ntsa, 2.4GHz yuav ua hauj lwm zoo dua; Txawm li cas los, tsis muaj cov kev txwv, 5 GHz yuav muaj kev xaiv sai dua.
Qhov kev sib txuas ua ke dual qhov cuab yeej xws li pom nyob rau hauv 802.11ac routers muab qhov zoo tshaj plaws ntawm ob hom kho vajtse ua ke los ntawm kev sib txuas ob hom xov tooj cua, kev tsim kho dua tshiab rau kev sib tham hauv tsev.
