4G vs 5G Networks

4G thiab 5G yog ob qho tib si mobile wireless nkag siv thev naus laus zis muab Ethernet ceev ntawm cov khoom siv txawb kom paub txog cov kev pabcuam ua si triply. Tam sim no 4G tau raug xa mus rau ntau lub tebchaws hauv Tebchaws Europe thiab North America. LTE thiab WiMAX yog ob lub thev naus laus zis sib txawv kom ua tiav 4G kev ceev ceev. Whereas 5G yog lub tswv yim nkaus xwb thiab tsis tau txhais raws li txoj cai.

5G tsis yog lub ntsiab lus los yog thev naus laus zis tab sis tib neeg xa cov thev naus laus zis uas tuaj yeem xa qhov nrawm tshaj 4G raws li 5G. Nws xav tias yuav ua tiav qhov twg hauv 2012 lossis 2013. Cov qauv tshiab lossis tshaj tawm tshaj 4G raug xa mus rau cov qauv qauv. zoo li 3GPP, WiMAX Forum lossis ITU-R. Tus qauv zoo tshaj 5G yuav tsum ua raws li cov kev cov nyom thiab ua kom haum rau qhov luv luv ntawm 4G Technology thiab 4G xa tawm cov kev paub dhau los. Txhawm rau nkag siab txog qhov tsim nyog thiab kev siv 5G tuaj yeem raug tsa thaum 4G rollout tiav thiab muaj kev paub dhau los. Yog li ib txwm 5G lub tswv yim yuav raug tsa nyob rau hauv ib qho chaw nyob ib ncig ntawm 2013-2015. Kev cia siab ceev yuav yog ntau yam ntawm Gigabit Ethernet. Cov thev naus laus zis no feem ntau yog siv hauv kev sib tham hauv xov tooj rov qab es tsis yog cov neeg siv kawg nkag mus.

4G (Forth Generation Networks)

Txhua tus neeg tsom mus rau tam sim no tig mus rau 4G vim nws cov ntaub ntawv tus nqi. Hauv kev sib txuas lus ceev ceev nws txoj kev xav muaj 100 Mbit / s (xws li tsheb ciav hlau lossis tsheb) thiab kev sib txuas lus qis qis lossis kev nkag mus ruaj khov yuav ua rau 1 Gbit / s. Qhov no yog kev hloov pauv loj hauv kev siv tshuab wireless.

Nws yog qhov sib npaug heev kom tau txais LAN lossis Gigabit Ethernet txuas rau lub xov tooj ntawm tes.

4G muab txhua qhov kev sib txuas lus IP nrog kev nkag mus rau cov xov tooj ntse, ntsiav tshuaj, laptops thiab txhua lub xov tooj ntse. Theoretically hais lus no 4G nkag mus ceev yog ntau tshaj Cable los yog DSL technologies nyob rau hauv lub siab 4G yog ceev tshaj ADSL, ADSL2 los yog ADSL2+.

Thaum 4G tau pib thiab yog tias koj muaj tsawg kawg 54 Mbits / s (qhov xwm txheej phem tshaj) rub tawm ntawm koj lub xov tooj ntawm tes lossis ntsiav tshuaj, koj tuaj yeem khiav ib daim ntawv thov hauv internet li koj ua hauv desktop computers. Piv txwv li koj tuaj yeem khiav Skype, YouTube, IP TV apps, Video on Demand, VoIP Client thiab ntau ntxiv. Yog tias koj muaj ib tus neeg siv VoIP ntsia ntawm koj lub cuab yeej tes koj tuaj yeem ua VoIP hu los ntawm koj lub xov tooj. Qhov no yuav tua lub suab nrov lag luam sai sai. Nyob rau tib lub sijhawm koj tuaj yeem sau npe rau txhua tus lej hauv zos rau koj tus neeg siv khoom VoIP mobile thiab pib txais kev hu xov tooj ntawm koj lub xov tooj ntawm IP. Piv txwv li yog tias koj nyob hauv New York koj tsis tas yuav tau txais NY tus lej hloov koj tuaj yeem sau npe Toronto tus lej txuas hauv koj lub xov tooj ntawm VoIP tus neeg siv. Txhua qhov chaw koj mus hauv 4G kev pab them nqi lossis thaj chaw Wi-Fi koj tuaj yeem tau txais kev hu rau koj tus lej Toronto. (Txawm tias koj tuaj yeem sau npe rau Switzerland tus lej tas thiab nyob hauv New York).

Koj tuaj yeem siv hu video hla IP thiab muaj ntsej muag sib ntsib ntawm mus. Koj tuaj yeem hu xov tooj dawb rau koj tus poj niam, tus hluas nkauj lossis txawm tuaj yeem muaj lub rooj sib tham video thaum koj mus ncig yog tias koj txuas nrog 4G.

Txawm tias 4G twb tau muab tso rau hauv Tebchaws Europe thiab North America (Qee lub chaw muab kev pabcuam yog Telnor, Tele2, Telia hauv Tebchaws Europe thiab Verizon, Sprint hauv Asmeskas), nws tseem nyob rau theem kev txhim kho. 4G, ntxiv rau lub hom phiaj 100 Mbits / s cov ntaub ntawv tus nqi rau kev txav cov neeg siv khoom thiab 1GB rau cov neeg siv nyob ruaj ruaj kuj tseem xav kom ua tiav cov kev pabcuam zoo dua rau cov neeg siv kawg yam tsis muaj kev poob qis thiab tso cai sib tham sib roaming thoob ntiaj teb.

Qhov txawv ntawm 5G thiab 4G

(1) 4G muab theoretically ze dua rau Gigabit Ethernet thaum cov neeg siv xav tau ntau Gigabit ceev los ntawm 5G.

(2) 4G tau siv rau hauv Backhauling Networks nrog rau cov neeg siv nkag mus rau hauv tes hauj lwm thaum cov neeg siv xav tias 5G yuav rov qab siv cov pob txha rov qab.
