Wireless kev sib txuas lus tshuab thiab lawv cov kev pab cuam

Hnub nyoog ntawm computer technology thiab kev siv technology tshiab kev kho tau tso cai rau txoj kev loj hlob ntawm ib qho yooj yim los mus siv nyob rau hauv lub neej txhua hnub ntawm cov neeg feem coob yog xws li ib tug tshaj plaws raws li ib tug wireless kev sib txuas lus system. Txawm hais tias peb tsis pom lawv, lawv cia ib ncig peb. Yuav ua li cas yog ib tug wireless system? Cov no yog cov tshuab uas rau cov ntaub ntawv hloov lwm lub tsev dab siv wireless (xov tooj cua) Pib ntsais koj teeb. Txawm nyob rau hauv lub sij hawm ua tsov ua rog, tej ntaub ntawv kis tau tus mob systems muaj tau ntse siv rau cov kev hloov ntawm ib qho tseem ceeb cov ntaub ntawv thiab yuav tsum tau agility. Nyob rau hauv peb lub neej ntawm wireless kev sib txuas lus tshuab tau tuaj raws li lub tsev networking, feem ntau nrog siv Internet. Nws yuav tsum tau muab sau tseg tias Internet kuj yog ib tug zoo ntawm ib tug thoob ntiaj teb network uas tso cai rau cov neeg los mus qhia ntaub ntawv los ntawm ntau qhov chaw ntawm lub ntiaj chaw.

Cov tsim nyog cov khoom rau ib tug wireless network yog xaiv nyob ntawm seb tus neeg siv yuav tsum tau, los yog nyob rau lub hom phiaj ntawm lub network nws tus kheej. Thaum ua cov kev xaiv, koj yuav tsum tau ua los ntawm tej yam kev. Piv txwv li, lub cov ntaub ntawv nqi ntawm lub network. Qhov no yog ib qho tseem ceeb cov yam ntxwv ntawm tej khoom siv, uas yuav tsis tau overlooked, los yog tej zaum koj yuav tsis tau cov kev kawm no. Cov kev ceev ntawm cov ntaub ntawv kis tau tus mob nyob rau hauv ib tug wireless network yuav ua tau sib npaug zos rau 50 Mbit / s. Ib txhia tshiab hom ntawm cov khoom uas siv 802.11n kev sib txuas lus standard, yuav kis cov ntaub ntawv ntawm speeds mus txog 5 x sai dua lub aforementioned. Qhov thib ob zoo tshaj yuav yog cheeb tsam txheej apparatus. Qhov loj nws yog, lub farther qhov kev ncua deb ntawm uas koj muaj peev xwm siv koj lub network. Thaum nrug muaj feem luj cov yam ntau yam kev pab them nqi yuav tsum tau ua los ntawm lub hom phiaj ntawm lub creation ntawm ib tug wireless network.

Wireless kev sib txuas lus yuav tsum muab qhov yuav tsum tau theem ntawm kev ruaj ntseg cov ntaub ntawv kis tau tus mob. Thaum yuav khoom khoom yuav tsum tau them rau kev mloog kom qhov no, vim hais tias tsis yog txhua txhua modems, routers los yog transmitters yog zoo muaj peev xwm mus encrypt koj lub teeb liab thiab tiv thaiv kom txhob cov ntaub ntawv to. Tam sim no, feem ntau twg, cov ntaub ntawv encryption, uas muaj peev xwm nti tiv thaiv cov ntaub ntawv los yog "ether" yog WEP, WPA2, WPA thiab lwm tus neeg. Raws li ib tug lwm txoj txoj kev kev tiv thaiv no feem ntau yog siv mus saib tau rau kev nkag mus kuaj daim ntawv pov, kev nkag kev tso cai thiab ib lo lus zais.

Mobility yuav ua tau ib tug yus feature ntawm cov khoom siv. Ntau nyob ntawm lub hom phiaj. Piv txwv li, koj yog ib tug loj muab kev pab thiab xav kom muab kev nkag tau mus rau koj lub network ntawm ob peb puas tus neeg uas yog nyob ze. Ces koj xav tau rau nruab ib tug tshwj xeeb ntauwd, uas yuav tsum tau nyob rau hauv ib qhov chaw thiab muab ib tug dlej teeb liab zog thiab cov ntaub ntawv tus nqi. Yog hais tias koj npaj mus npaj ib tug wireless kev sib txuas lus system nyob rau hauv koj lub chaw ua hauj lwm los yog nyob rau hauv tsev, ces koj tsuas tau txais ib tug wireless modem los yog ib tug router, uas muaj ib tug compact loj thiab muaj peev xwm muab tau yooj yim tsiv mus rau tej kev yooj yim rau koj "lub".

Lub tswvyim ntawm ib tug wireless network muaj kuj muaj xws li muaj peev xwm mus hloov ntawm ntau yam kev nkag ntsiab lus tsis muaj tsis ntawm cov ntaub ntawv. Qhov no feature borrowed los ntawm lub mobile network tswv, thiab siv nws yog tsim nyog los muaj kev tshwj xeeb cov khoom.
