802.11g yog ib qho ntawm IEEE Lub Tsev Haujlwm Saib Xyuas Hluav Taws Xob thiab Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob) cov qauv ntawm Wi-Fi wireless networking technology. Nws tau pom zoo thaum Lub Rau Hli 2003 thiab hloov cov qauv qub ntawm 802.11b. Cov qauv tshiab, nrawm dua ntawm tus qauv txij li tau hloov pauv, tab sis 802.11g-raws li cov cuab yeej tseem siv.
Qhov ceev ntawm lub khoos phis tawj network feem ntau yog hais txog bandwidth raws li units ntawm megabits ib ob (Mbps) lossis gigabits ib ob (Gbps). Qhov ntsuas nrawm tshwm sim ntawm kev tshaj tawm thiab ntim khoom rau txhua yam khoom siv hauv computer network.
802.11g Rated Ceev
Qhov ntsuas ceev ntawm 802.11g cov khoom siv sib txuas yog 54 Mbps. Txawm li cas los xij, 802.11g thiab lwm yam Wi-Fi network raws tu qauv muaj xws li ib qho tshwj xeeb hu ua dynamic rate scaling. Thaum lub teeb liab wireless ntawm ob qho khoom siv txuas nrog Wi-nkaus tsis muaj zog, kev sib txuas tsis tuaj yeem txhawb nqa qhov ceev tshaj plaws. Hloov chaw, Wi-Fi raws tu qauv txo nws qhov siab tshaj plaws kev sib kis ceev mus rau tus lej qis kom tswj tau qhov kev sib txuas.
Nws yog ib qho rau 802.11g kev sib txuas khiav ntawm 36 Mbps, 24 Mbps, lossis qis dua. Thaum dynamically teeb tsa, cov txiaj ntsig no dhau los ua qhov theoretical siab tshaj plaws ceev rau qhov kev sib txuas, uas tseem qis dua hauv kev xyaum vim yog Wi-Fi raws tu qauv.
kab hauv qab
Qee lub tsev sib tham hauv tsev wireless raws li 802.11g thiab raug xaiv los ua Xtreme G thiab Super G network routers thiab adapters txhawb nqa 108 Mbps bandwidth. Txawm li cas los xij, cov khoom siv no siv cov khoom txuas ntxiv mus rau 802.11g tus qauv kom ua tiav kev ua tau zoo dua. Yog tias cov khoom lag luam 108 Mbps txuas nrog tus qauv 802.11g, nws qhov kev ua tau zoo rov qab mus rau 54 Mbps qhov siab tshaj plaws.
Vim li cas 802.11g Networks khiav qeeb dua 54 Mbps
Tsis yog 54 Mbps lossis 108 Mbps tus lej tag nrho sawv cev qhov tseeb nrawm koj yuav muaj kev paub dhau los ntawm 802.11g network. Qhov ntsuas 54 Mbps sawv cev rau qhov siab tshaj plaws theoretical nkaus xwb. Nws ntsib cov nyiaj siv ua haujlwm tseem ceeb los ntawm cov ntaub ntawv network raws tu qauv uas kev sib txuas Wi-Fi yuav tsum pauv rau kev ruaj ntseg thiab kev ntseeg siab. Cov ntaub ntawv tseem ceeb sib pauv ntawm 802.11g tes hauj lwm ib txwm tshwm sim ntawm tus nqi qis dua 54 Mbps.
