Yuav Paub
- Wireless-N broadband routers thiab network adapters yuav tsum tau txuas thiab khiav hauv channel sib cog lus hom kom khiav ntawm max ceev.
- Qee 802.11n iav tsis tuaj yeem txhawb nqa kev sib raug zoo channel.
Kab lus no piav qhia qhov yuav tsum tau ua rau kev sib txuas 802.11n kom khiav ntawm nws qhov siab tshaj plaws.
802.11n thiab Kev Txhaum Cai Channel
Ib 802.11n Wi-Fi network kev sib txuas txhawb nqa txog 300 Mbps ntawm kev ntsuas theoretical bandwidth nyob rau hauv cov xwm txheej zoo tshaj plaws. Txawm li cas los xij, qhov txuas 802.11n qee zaum ua haujlwm ntawm qeeb qeeb xws li 150 Mbps thiab hauv qab.
Rau qhov kev sib txuas 802.11n kom khiav ntawm nws qhov siab tshaj plaws, Wireless-N broadband routers thiab network adapters yuav tsum tau txuas thiab khiav hauv qhov hu ua channel sib txuas hom.
Nyob rau hauv 802.11n, kev sib txuas lus siv ob qhov sib txuas Wi-nkaus ib txhij los ua ob npaug ntawm qhov txuas wireless bandwidth piv rau 802.11b / g. Tus qauv 802.11n qhia txog 300 Mbps theoretical bandwidth yog muaj thaum siv kev sib txuas nrog channel.
Yog tsis muaj nws, kwv yees li 50 feem pua ntawm cov bandwidth no ploj (qhov tseeb me ntsis ntxiv vim yog cov txheej txheem kev txiav txim siab), thiab nyob rau hauv cov ntaub ntawv no, 802.11n cov cuab yeej feem ntau tshaj tawm cov kev sib txuas hauv 130 txog 150 Mbps rated range.
Channel bonding ua rau muaj kev pheej hmoo cuam tshuam nrog Wi-nkaus network nyob ze vim qhov nce spectrum thiab lub zog nws siv.
Tshuaj 802.11n Channel Bonding
802.11n cov khoom lag luam ib txwm tsis ua kom muaj kev sib raug zoo channel los ntawm lub neej ntawd. Hloov chaw, cov khoom lag luam no khiav hauv cov qauv ib leeg-channel kom muaj kev pheej hmoo ntawm kev cuam tshuam tsawg. Ob lub router thiab Wireless-N cov neeg siv khoom yuav tsum tau teeb tsa kom khiav hauv txoj kev sib koom ua ke ua ke kom ua tiav cov txiaj ntsig kev ua tau zoo.
Cov kauj ruam los teeb tsa kev sib txuas channel sib txawv nyob ntawm cov khoom. Lub software qee zaum hais txog ib leeg-channel hom ua haujlwm 20 MHz (20 MHz yog qhov dav ntawm Wi-nkaus channel) thiab channel sib txuas hom raws li 40 MHz ua haujlwm.
Tham nrog koj tus router cov ntaub ntawv rau cov lus qhia txog kev ua kom muaj kev sib raug zoo channel.
txwv 802.11n Channel Bonding
802.11n cov cuab yeej tuaj yeem ua tsis tiav hauv qhov siab tshaj plaws (300 Mbps) kev ua tau zoo rau cov laj thawj no:
- Qee 802.11n iav tsis tuaj yeem txhawb nqa kev sib raug zoo channel. Piv txwv li, hom kev teeb liab wireless no yog tsoomfwv tswj hwm hauv qee lub tebchaws xws li UK.
- Yog tias 802.11n network suav nrog txhua tus neeg siv 802.11b / g, kev ua haujlwm hauv network yuav raug cuam tshuam tsis zoo, nyob ntawm tus router lub peev xwm. Vim tias 802.11b / g cov neeg siv khoom tsis txhawb kev sib txuas ntawm cov channel, cov no yuav tsum tau teeb tsa kom zoo nrog cov sib xyaw hom Wireless-N router kom txo qis kev cuam tshuam.
- Kev cuam tshuam los ntawm lwm lub 802.11n network nyob ze tuaj yeem tiv thaiv Wireless-N router los ntawm kev txhawb nqa kev sib txuas ntawm cov channel sib txuas. Qee lub wireless-N routers cia li poob rov qab rau ib leeg-channel ua haujlwm thaum lawv ntes wireless cuam tshuam ntawm cov channel.
- Txawm tias kev sib txuas tuaj yeem khiav ntawm 300 Mbps, nws tsis tau txhais hais tias cov khoom siv tuaj yeem rub tawm thiab xa cov ntaub ntawv sai sai. Ib qho laj thawj tseem ceeb rau qhov no yog qhov kev tso npe ISP tsis tso cai rau kev nrawm (xws li yog tias koj tsuas yog them rau 100 Mbps).
Raws li nrog rau lwm cov qauv kev sib tham, cov ntawv thov khiav ntawm 802.11n network feem ntau pom tsawg dua qhov bandwidth tshaj qhov ntsuas qhov siab tshaj plaws, txawm tias muaj kev sib txuas ntawm cov channel. A 300 Mbps rated 802.11n kev sib txuas feem ntau yields 200 Mbps lossis tsawg dua ntawm cov neeg siv cov ntaub ntawv dhau los.
Single Band vs. Dual Band 802.11n
Qee Wireless-N routers (hu ua N600 khoom) tshaj tawm kev txhawb nqa rau 600 Mbps ceev. Cov routers no tsis muab 600 Mbps ntawm bandwidth ntawm ib qho kev sib txuas tab sis 300 Mbps channel sib txuas sib txuas ntawm txhua qhov ntawm 2.4 GHz thiab 5 GHz zaus bands.
