WiMax thiab LTE yog ob qho txuj ci tshiab rau high-speed mobile broadband Internet. Ob WiMax thiab LTE tshwm sim kom muaj cov hom phiaj zoo sib xws rau peev txheej ua thoob ntiaj teb cov ntaub ntawv wireless txuas rau xov tooj ntawm tes , laptops, thiab lwm cov khoom siv. Vim li cas ho ua li ob zaug no sib tw sib tw nrog sib, thiab qhov txawv ntawm WiMax thiab LTE yog dab tsi?
Cov chaw pabcuam sib txawv thiab cov lag luam kev lag luam rov qab los ntawm WiMax lossis LTE, los yog ob qho tib si, nyob ntawm seb cov kev siv tshuab ua haujlwm zoo li cas rau lawv cov lag luam. Hauv Teb Chaws Asmeskas, piv txwv li, tus neeg zov me nyuam cellular Sprint backs WiMax thaum nws cov neeg competitors Verizon thiab AT & T txhawb LTE. Cov tuam txhab tsim muaj cai xaiv ib qho los sis sib txuas raws li lawv qhov peev xwm los tsim kho vajtse ntau dua lossis tsawg dua.
Tsis yog cov khoom siv technology yuav tsum hloov Wi-Fi cov tsev tes hauj lwm thiab cov hotspots. Rau cov tau txais kev pab, ces, qhov kev xaiv ntawm LTE thiab WiMax tuaj yeem ua rau cov kev pabcuam uas muaj nyob rau hauv lawv cheeb tsam thiab muaj kev ceev dua thiab kev cia siab rau.
Muaj Txaus
Cov chaw pabcuam hauv cellular xws li Verizon hauv Tebchaws Meskas npaj siab mus tso tawm Long Term Evolution (LTE) cov cuab yeej siv raws li kev hloov kho rau lawv cov network uas twb muaj lawm. Cov neeg zov me nyuam tau nruab thiab pib xeem qee cov cuab yeej siv LTE hauv kev sib hais plaub, tab sis cov tes hauj lwm tseem tsis tau qhib rau pej xeem. Kwv yees rau thaum thawj LTE tes hauj lwm yuav muaj ntau yam los ntawm tom qab hauv xyoo 2010 rau caij nyoog hauv xyoo 2011.
WiMax, ntawm qhov tod tes, twb muaj nyob rau qee qhov chaw. WiMax ua rau kev nkag siab tshwj xeeb tshaj yog nyob rau thaj chaw uas cov kev pabcuam 3G tsis muaj tam sim no. Txawm li cas los xij, thawj zaug uas tau ua tiav rau WiMax tau siv ntau qhov chaw xws li Portland (Oregon, Tebchaws USA), Las Vegas (Nevada, USA) thiab Kauslim teb qhov chaw ua haujlwm hauv Internet xws li fiber , cable, thiab DSL .
Ceev
Ob leeg WiMax thiab LTE cog lus ntau dua ceev thiab muaj peev xwm dua piv rau 3G thiab wireless broadband network. Txuas kev siv Internet yuav ua raws li ntawm 10 thiab 50 Mbps kev sib txuas ceev. Tsis txhob cia siab tias yuav pom li no ceev nrooj kom txog thaum cov yees tau paub ntau xyoo tom ntej no. Cov neeg siv ntawm Clearwire WiMax cov kev pabcuam hauv Tebchaws Meskas, piv txwv li, feem ntau qhia txog kev ceev ceev hauv qab 10 Mbps uas yog nyob ntawm qhov chaw, sijhawm hnub thiab lwm yam.
Qhov tseeb tiag, nrog rau lwm hom kev pabcuam hauv Internet, qhov tseeb ntawm kev sib txuas yog nyob ntawm seb hom subscription xaiv li cas nrog rau qhov zoo ntawm tus neeg muab kev pabcuam.
Wireless Spectrum
WiMax tsis tau txhais tias yog ib qho chaw ruaj khov rau nws cov wireless signaling. Sab nraum Teb Chaws Asmeskas, cov khoom siv WiMax muaj kev sib txuas lus 3.5 GHz raws li hais tias yog ib qho qauv siv rau kev dav hlau mobile broadband feem ntau. Hauv Teb Chaws Asmeskas, tus 3.5 GHz band feem ntau yog tseg rau kev siv los ntawm tsoom fwv. WiMax cov khoom nyob rau hauv Teb Chaws Asmeskas tau siv 2.5 GHz hloov tab sis ntau lwm hom yog tseem muaj. LTE cov chaw kho mob hauv Tebchaws Meskas npaj siab siv ob peb hom sib tw nrog 700 MHz (0.7 GHz).
Siv ntau dua cov paib tso cai tso cai rau wireless network mus theoretically nqa ntau cov ntaub ntawv thiab yog li muab tau ntau dua bandwidth . Txawm li cas los xij, tus yees feem ntau tuaj yeem pheej mus qis dua (cuam tshuam qhov chaw pab them) thiab muaj kev cuam tshuam rau kev cuam tshuam kev cuam tshuam .
