Thaum ntxov ntawm 5G, kev sib tham txog kev lag luam ntawm backhaul network phiaj xwm feem ntau yog ua kom muaj fiber ntau, thiab nws cia siab tias fiber ntau ib leeg tuaj yeem ua tau 5G' s siab siab backhaul muaj peev xwm xav tau. Raws li thev naus laus zis tau tsim, txawm li cas los xij, cov kev xav ntxov no tau pom tias muaj qhov tsis raug. Niaj hnub no, microwave thev naus laus zis yog kev sib tw rau cov fiber ntau.
Txhawm rau kom nkag siab txog qhov kev xa xov hluav taws xob xa khoom yuav tsim los pab txhawb 5G cov kev pabcuam," Tus Neeg Teb Xov Tooj Txog Kev Ua Haujlwm rau 5G Kev Tshawb Fawb Kev Ua Lag Luam Kev Tshawb Fawb Kev Ua Lag Luam" tau pib thaum Lub Tsib Hlis 2020. Daim ntawv soj ntsuam tau sib tham txog 86 cov neeg teb xov tooj tsim nyog los ntawm thoob plaws ntiaj teb uas tau koom nrog lawv cov kev xav txog teeb meem kev xa mus thiab cov sijhawm, kev npaj ua ntej network thiab wireless Access network (RAN) centralization, routing thiab synchronization, thiab kuaj. 5G tes hauj lwm.
Tau cov txheej txheem prequel
Nrog cov ntaub ntawv tus nqi dhia mus txog 10Gbps, microwave backtracking yog rov qab los sai sai rau kev ua lag luam raws li kev muaj peev xwm 5G rov qab muaj txiaj ntsig. Hauv kev soj ntsuam, 35 feem pua ntawm cov neeg teb cov neeg tau hais tias 10 Gbps microwaves yog" tseem ceeb heev" rau 5G kis.
Feem ntau, hauv 5G xHaul, lub prequel tau qhov kev sib tw loj tshaj plaws thiab thaj chaw ntawm kev lag luam txhawj xeeb vim nws qhov kev xav tau qhov ntau thiab qhov txwv qeeb, piv rau nruab nrab ntawm tsheb. Cov kev xav ntxov tau pom tias kev kho qhov muag tau daws qhov teeb meem no. Tab sis kev soj ntsuam cov ntaub ntawv qhia tias kev sib txuas wireless yuav yog qhov kev xaiv rau lub vij vuam prequel, tshwj xeeb tshaj yog nyob rau millimeter-wave frequencies saum 30 GHz, uas tuaj yeem nce cov ntaub ntawv nce mus rau 25Gbps lossis siab dua. Raws li kev sojntsuam 2020 5G kev sib kis, microwave / millimeter-yoj sib kis yuav muaj 18 feem pua ntawm 5G kev sib kis uantej.
Yuav kom paub meej, cov neeg ua haujlwm tab tom nrhiav rau fiber ntau raws li lawv cov khoom siv prequel, tab sis microwave / millimeter yoj yuav yog qhov kev xaiv nyob rau hauv rooj plaub uas muaj fiber ntau tsis muaj lossis txwv. Cov qauv no tuaj yeem sib txawv ntawm thaj chaw, raws li cov peev txheej ntawm cov cuab yeej hluav taws xob optical fiber, kev muaj peev xwm ntawm nyiaj txiag thiab lwm yam nyob ntawm ntau lub teb chaws.
Cov ntaub ntawv thov microwave
Qhov xaus lus nthuav tawm los ntawm cov ntaub ntawv yog cov neeg teb xov tooj ntseeg tias microwave yuav daws qhov teeb meem 5G hauv txhua qhov teeb meem tau siv. Raws li xav pom, macro rov qab yog tus naj npawb thib ib microwave thawj. Ntawm cov neeg teb, 49% tau xaiv macro rov qab siv rooj plaub nrog qhov ceev ntawm 10Gbps lossis siab dua, thaum 40% xaiv macro rov qab tsawg dua 10Gbps. Tab sis lwm yam siv rooj plaub tseem tau qhab nia ntau. Ntau tus neeg khiav dej num pom Txoj Kev Macro thiab Small Cell rov qab mus ncig raws li siv tau cov teeb meem siv microwave, nrog rau ib feem peb lossis ntau tus neeg teb tau qhov muaj feem ob qhov rooj plaub no. Txawm hais tias nyob hauv 10Gbps cov ntaub ntawv cov nqi, microwave muaj kev nkag tau mus ua si, nrog 23% ntawm cov neeg siv lus teb xaiv lawv raws li qhov kev xaiv xav tau.
Tag nrho txhua qhov, cov ntaub ntawv qhia txog lub zog muaj zog rau microwave kev xa mus, txawm tias nyob rau hauv kev siv cov ntaub ntawv uas ib txwm muaj kev txwv rau fiber ntau qhov muag.
