Yuav tus haib 5G Wireless Abandon Fiber?
5G yog lub "tsib tiam" ntawm cov tes hauj lwm wireless. Nws yuav qhia ntau yam khoom siv, nrog rau ob qho tib si ntawm mobile thiab tsau vaj tse, piv txwv li ob lub xov tooj ntawm tes, cov twj siv tau thiab cov cav uas tswm sim yuav yog wireless. Yog li ntawd puas txhais tau hais tias yav tom ntej peb yuav tsum tsis muaj fiber ntau cab khiav ncig?
Yav tom ntej 5G Wireless Yuav Nyob Hauv Fiber
Thaum xub thawj siab, neeg yuav xav tias 5G wireless yuav ua hauj lwm ntawm xov tooj cua cov cim thiab tsis muaj fiber. On qhov tsis zoo, qhov zoo ntawm yav tom ntej 5G ho nyob ntawm fiber ntau.
Tsav ceev yuav tsum tau Fiber ntau
Hauv qab ntawm lub ntiaj teb wireless infrastructure lies loj loj interwoven los ntawm fiber ntau fiber ntau cables. Thiab ntawm tam sim no 90% ntawm tag nrho cov internet tsheb tawm hla lub fiber ntau wireline, txawm tias nws thaum kawg terminates nyob rau hauv ib tug wireless ntaus ntawv. 5G yog tsom rau ntawm kev sib txuas ntawm 1-10 Gbps, uas yog kaum rau lub sij hawm ntau dua 4G. Lub tsheb ciav hlau yooj yim mus rau cov chaw zov me nyuam yuav xav tau kev thauj xov xwm uas muaj peev xwm ntawm kev siv bandwidth thiab ntev, thiab fiber ntau qhov kev xaiv zoo tshaj plaws rau yav tom ntej ntawm tag nrho cov khoom siv. Rau qee cov tuam txhab loj uas paub txog lub luag haujlwm ntawm fiber ntau tau nqis peev ntxiv rau hauv kev npaj rau 5G xa mus, xws li Verizon.
5G High Performance Yuav Tsum Tau Fibre
Yuav kom ua tau raws li cov hom phiaj 5G tau cog lus tseg (saib daim qauv hauv qab), yuav tsum muaj fiber ntau dua thoob ntiaj teb. Vim hais tias qhov kawg yuav tsis yog hais txog kev siab dua, tab sis lub caij nyoog tsawg latency, network ntau haiv neeg, muaj thiab cov kev pabcuam uas txhua tus yuavtsum tau muaj lub hauv paus ntawm fiber ntau.
| 1 | 1-10Gbps txuas mus xaus cov ntsiab lus hauv thaj teb (piv txwv li tsis yog theoretical maximum) |
| 2 | 1 millisecond kawg-rau-kawg round trip ncua (latency) |
| 3 | 1000x bandwidth rau ib cheeb tsam twg |
| 4 | 10-100 x xov tooj ntawm cov khoom siv txuas |
| 5 | (Kev pom ntawm) 99.999% muaj |
| 6 | (Kev pom ntawm) 100% kev pab |
| 7 | 90% txo ntawm kev siv hluav taws xob hauv kev pabcuam |
| 8 | Mus txog 10 xyoo roj teeb lub neej rau qis zog, tshuab hom ntaus ntawv |
Lub hom phiaj ntawm 5G network ntau haiv neeg, muaj thiab muaj peev xwm tau txais los ntawm kev xa xov tawm ntawm cov xov tooj me me / xov tooj sib txuas (DAS) txuas los ntawm fiber ntau. Cov chaw me me / DAS (100-200 m / tsawg tshaj 30 m) yog nyob ze rau cov neeg siv nyob rau hauv qhov chaw (ntawm lub teeb los yog chaw sawv nruab nrab) piv rau qhov chaw hauv xov tooj (3-6 km), thiab muaj peev xwm pab tau ntau yam ntawm cov technologies thiab frequencies .
Los ntawm kev xa ntau me me ntawm qhov chaw / DAS, nws muaj peev xwm tsawg dua cov dav hlau cov neeg siv kev pab los ntawm txhua qhov chaw thiab yog li muaj peev xwm tshaj li ib tus neeg siv kev pabcuam. Yog tias qhov chaw me me / DAS yuav tsum tau ua haujlwm zoo rau yav tom ntej 5G, lub thev rov qab yuav tsum muaj fiber ntau vim tias tooj liab lossis cua tsis tuaj yeem pab txhawb cov tsheb loj uas yuav tsim los ntawm 5G centralized wireless access network (C-RAN).
Ntxiv rau kev muaj peev xwm, kuj xav tias tus nqi-ua tau zoo thiab TCO (tag nrho cov nqi ntawm cov tswv cuab), fiber ntau ntawm cov chaw hauv xov tooj los yog cov pej thuam pom zoo qhov kev xaiv. Thiab ntawm chav kawm ntau kev sib txuas los ntawm cov chaw no rau cov chaw zov me nyuam txhais tau tias ntau lub fiber ntau yuav muab ntsia.
Lub Final Answer Yog ...
5G wireless yuav tsis tso tseg fiber ntau. Es tsis txhob nws cov khoom xa tuaj yeem tso siab rau qhov muaj cov tswv yim ntawm fiber ntau. Thiab cov fiber ntau yuav ua rau kom muaj peev xwm thiab qis qis rau yav tom ntej ntawm wireless networks.
