Qhov Tseem Ceeb Ntawm Qhov Tseem Ceeb Me Nyuam
Ib qho ntawm lub ntiaj teb cov nyiam tshaj plaws network technologies, WI-Fi kev sib txuas txhawb ntau lab tus neeg hauv tsev, cov lag luam thiab cov chaw nyob thoob plaws ntiaj teb. Nws yog xws li ib feem ntawm peb lub neej niaj hnub tam sim no hais tias nws yooj yim mus Wi-nkaus rau kev tso cai, nws muaj peev xwm yog kev zam txim yog tias koj tsis paub cov ntsiab lus li cas Wi-nkaus ua haujlwm.
Ntawm no yog tus primer rau Wi-Fi qhov tseem ceeb yuav muab koj ib qho kev nkag siab zoo li cas nws ua haujlwm.
Wireless Broadband Routers Tseem Muaj Cov Ntsiab Lus Wi-nkaus Cov Lus Qhia
Ib qho point point (AP) yog hom wireless hub tseem ceeb rau kev tswj cov kev sib koom tes network ntawm ntau tus neeg tau txais kev pab. Ib qho laj thawj yog vim li cas cov wireless broadband routers ua rau cov hauv paus tsev kawm ntawv yooj yim dua los tsim yog tias lawv ua hauj lwm li Wi-nkaus cov ntsiab lus. Cov neeg khiav dej num hauv tsev ua lwm yam hauj lwm tseem ceeb, dhau li, xws li khiav network firewall .
WI-Fi Connections Tsis Txhob Siv Lub Nkag Mus Siv
Qee cov neeg xav hais tias lawv yuav tsum nrhiav ib lub router, ib qho chaw hotspot lossis lwm hom kev nkag mus rau hauv thiaj li tsim Wi-nkaus kev sib txuas. Tsis muaj tseeb!
WI-Fi kuj txhawb ib hom kev txuas hu ua hom hos uas tso cai rau cov cuab yeej txuas mus rau ib leeg hauv ib qho yooj yim peer-to-peer network. Xav paub ntau ntxiv txog yuav ua li cas los tsim ib qho kev sib tw ua pawg Wi-nkaus .
Tsis yog tas nrho cov Wi-nkaus Hom Yog Tshaj Tawm
Cov neeg muag khoom lag luam tsim thawj version ntawm Wi-Fi ( 802.11 ) rov qab rau xyoo 1997. Cov lag luam rau cov khoom siv khoom siv tau pib thaum xyoo 1999 thaum 802.11a thiab 802.11b ua cov qauv kev cai.
Muaj qee ntseeg hais tias txhua qhov WI-nkaus system tuaj yeem txuas nrog lwm qhov Wi-nkaus system yog tias tag nrho lawv qhov kev ruaj ntseg zoo sib xws. Thaum nws muaj tseeb tias 802.11n , 802.11g thiab 802.11b khoom siv Wi-nkaus khoom siv ua ke ua ke, 802.11a tus qauv tsis sib xws nrog lwm cov. Cov kev qhia tshwj xeeb hauv Wi-Fi nkag tau cov kev txhawb nqa 802.11a thiab 802.11b (lossis siab tshaj) cov xov tooj siv yuav tsum tau siv los ua tus choj ob.
Lwm cov teeb meem sib raug teeb meem kuj tuaj yeem tshwm sim ntawm cov khoom siv Wi-Fi ntawm cov neeg muag khoom sib txawv yog neb ob leeg tsim lawv cov khoom siv Wi-nkaus siv cov khoom siv tsis txhim kho dua. Zoo hmoo, kev tsis sib haum xeeb zoo li cov no feem ntau tsis pom muaj hnub no.
WI-nkaus Kev Tshaj Tawm Kev Tshaj Tawm Ntau Nrog Ntau
Thaum koj koom nrog Wi-nkaus network thiab qhov kev taw qhia nkag nyob ze, koj ntaus ntawv yuav feem ntau txuas ntawm nws qhov kev zov me nyuam ntau tshaj plaws (xws li, 54 Mbps rau feem sib txuas 802.11g).
Thaum koj tsiv tawm ntawm AP, tab sis, koj qhov kev tshaj tawm tias kev sib txuas yuav poob rau 27 Mbps, 18 Mbps, thiab qis dua.
Ib qho tsim muaj cleverly tsim ntawm Wi-nkaus hu ua dynamic rate scaling ua rau qhov tshwm sim no. WI-Fi tswj tau kev txhim khu kev qha ntev dua thaum nws hloov cov ntaub ntawv qeeb qeeb los ntawm kev tsis txhob muaj kev cuam tshuam dej nyab nrog cov ntaub ntawv thiab rov qab thov kom tshwm sim thaum muaj ib tus neeg tau txais kev pab pib poob qis ntawm kev ua nws cov lus.
Ib qhov Wi-nkaus Network Tau Txais Kev Loj Loj lossis Tsawg Luv Luv Luv
Feem ntau ntawm Wi-nkaus lub network nws txawv nyob ntawm seb hom obstructions lub xov tooj cua signals ntsib ntawm kev twb kev txuas endpoints. Thaum lub sij hawm 100 feet (30m) los yog ntau ntawm qhov sib txawv, qhov teeb meem ntawm Wi-nkaus tsis tuaj yeem mus txog ib nrab ntawm qhov kev deb yog tias muaj kev cuam tshuam hnyav nyob rau hauv lub xov tooj cua teeb liab txoj kev.
Yog hais tias ib tug neeg khiav dej num txais qhov zoo tshaj plaws Wi-Fi ntau extending li , lawv tuaj yeem ncav cuag lawv lub network kom kov yeej cov kev txwv thiab nthuav nws ntau yam hauv lwm cov lus qhia. Ob peb Wi-nkaus tes hauj lwm ib mais ntawm 125 mais (275 km) thiab ntau tshaj twb tau tsim los ntawm network enthusiasts ntau xyoo.
WI-Fi Tsis yog Tsuas Yog Tsa Wireless Networking
Cov khoom xov xwm thiab chaw qee zaus kuj xa mus rau txhua hom wireless network li Wi-nkaus. Thaum Wi-nkaus tsis tshua muaj neeg nyiam, lwm hom kev siv tshuab wireless kuj siv rau ntau yam. Smartphones, piv txwv li, feem ntau siv Wi-Fi ua ke nrog cov kev pabcuam hauv xovtooj xws li 4G LTE lossis cov laus dua 3G.
Bluetooth wireless tseem yog ib txoj hauv kev nyiam txuas xov tooj ntawm tes thiab lwm cov khoom siv sib txig sib txuas (los yog rau ib qho ntawm ib lub lag luam xws li cov kaus mom) kom dhau luv dua.
Cov cuab yeej hluav taws xob hauv tsev siv ntau hom xov tooj cua sib txuas lus luv luv xws li Insteon thiab Z-Wave .
