C-Band yog dab tsi?
C-Qhab hais txog ib feem ntawm microwave zaus ntau ntau, feem ntau yog kev nthuav dav los ntawm 4 GHz rau 8 GHz. Nws yog dav siv hauv satellite kev sib txuas lus, xov tooj cua, thiab TV tshaj plaws hauv TV. Tshwj xeeb, C-band ntau zaus feem ntau yog siv 3.7 GHz rau 4.2 GHz (Downlink) thiab 5.925 GHz (Uplink). Cov cim hauv cov zaus no band tuaj yeem taug kev ntev thiab cov vaj tse nkag tau zoo dua, ua rau qee qhov tseem ceeb ntawm kev sib txuas lus.
Qhov tseem ceeb ntawm C-Band rau 5G
Hauv kev txhim kho 5g tes hauj lwm, c-band spectrum yog suav tias yog ib feem ntawm nws lub peev xwm los sib npaug nrawm, kev pab cuam kis tau. Cov ntsiab lus hauv qab no hais txog qhov tseem ceeb ntawm C-Band rau 5G:
High bandwidth rau cov ntaub ntawv xa tawm sai:
C-band muaj cov bandwidth, txhawb nqa cov ntaub ntawv ntau dua. Qhov no yog qhov tseem ceeb rau 5g tes hauj lwm, uas xav tau los ua cov ntaub ntawv loj ntawm cov ntaub ntawv thiab kev txhawb nqa banding qub xws li 4K video streaming kev tseeb (ar), thiab virtual kev muaj tiag (vr).
Kev tiv thaiv dav dav:
Piv rau cov zaus ntau zaus zoo li millimeter very wave (Mmwave), C-Band muab cov chaw zoo dua, muaj txiaj ntsig zoo rau cov tuam tsev thiab lwm yam kev thaiv. Qhov no ua rau c-band tshwj xeeb muaj txiaj ntsig zoo nyob hauv nroog ib puag ncig
Qhov kev xaiv sib luag rau network xa mus:
C-bz bz nyob ntawm tsawg-zaus thiab millimeter koj txoj kev yoj, muab ib qho kev xaiv sib npaug. Thaum cov bands tsawg (piv txwv li, 700 mhz) muab kev nyab xeeb dav, lawv tau muaj qhov zoo rau cov ntaub ntawv nrawm nrawm. Conversely, millimeter koj txoj hlua khi (piv txwv li, saum toj kawg nkaus 24 GHZ) muab cov bandwidth siab tab sis muaj kev pab them tsawg thiab yooj yim thaiv los ntawm cov nyom. C-Qhab tsam sib npaug los ntawm kev muab cov khoom siv pov hwm tsim nyog thiab kev sib kis tau zoo, ua rau nws lub zog tseem ceeb rau 5G kev siv.
Reallopation ntawm Spectrum Cov Khoom Siv:
Raws li 5g kev nce qib, ntau lub teb chaws yog realallocating c-band spectrum cov peev txheej los ntawm satellite sib txuas lus lossis lwm yam kev siv rau 5G tes hauj lwm. Qhov kev kho mob no yuav pab dawb ntau cov peev txheej ntau ntxiv, txhawb kev nthuav dav ntawm 5g tes hauj lwm.
C-Band tuav cov kev xaiv tswv yim tseem ceeb hauv 5G tes hauj lwm. Nws muab cov kev tiv thaiv siab thiab cov kev pab them zoo uas yuav tsum muaj rau kev sib txuas tau muaj zog thiab kev sib txuas nrawm hauv 5G tes hauj lwm. Zoo li Ntiaj Teb 5G tes hauj lwm txuas ntxiv rau yob tawm, kev siv C-Band yuav txuas nrawm ntxiv ua kom nrawm dua ntawm kev saws me nyuam, tso lub hauv paus rau yav tom ntej digital lub neej.
