Kev tshuaj xyuas ntawm kev siv thiab kev faib tawm ntawm 1250MHz zaus band

Lub zaus 1250MHz nyob hauv txoj haujlwm tseem ceeb hauv xov tooj cua spectrum thiab siv dav hauv cov teb xws li kev sib txuas lus satellite thiab navigation systems. Nws qhov kev xa tawm teeb liab ntev thiab qhov attenuation qis ua rau nws muaj txiaj ntsig zoo hauv cov ntawv thov tshwj xeeb.

Cov chaw thov tseem ceeb:

Kev sib txuas lus satellite: Lub zaus 1250MHz feem ntau yog siv rau kev sib txuas lus ntawm cov satellites thiab cov chaw nres tsheb hauv av. Txoj kev sib txuas lus no tuaj yeem ua tiav thaj chaw dav dav, muaj qhov zoo ntawm kev xa xov tooj ntev thiab muaj peev xwm tiv thaiv kev cuam tshuam zoo, thiab siv dav hauv cov teb xws li kev tshaj tawm hauv TV, kev sib txuas lus mobile thiab kev tshaj tawm satellite.

Lub kaw lus navigation: Hauv 1250MHz zaus band, L2 zaus band ntawm Global Satellite Positioning System (GNSS) siv qhov zaus no rau qhov chaw tseeb thiab taug qab. GNSS yog siv dav hauv kev thauj mus los, aerospace, nkoj navigation thiab kev tshawb nrhiav geological.

Qhov xwm txheej tam sim no ntawm kev faib spectrum:

Raws li "Cov Cai Tswjfwm Kev Faib Xov Tooj Cua ntawm Lub Tebchaws Suav", kuv lub tebchaws tau ua cov kev faib tawm ntawm cov zaus xov tooj cua kom tau raws li qhov xav tau ntawm cov lag luam sib txawv.

Txawm li cas los xij, cov ntaub ntawv tshwj xeeb ntawm kev faib tawm ntawm 1250MHz zaus band tsis tau piav qhia meej hauv cov ntaub ntawv rau pej xeem.

Kev faib tawm spectrum thoob ntiaj teb:

Thaum Lub Peb Hlis Ntuj xyoo 2024, cov thawj coj hauv Tebchaws Meskas tau tshaj tawm Txoj Cai Spectrum Pipeline xyoo 2024, uas tau tshaj tawm tias yuav muag qee cov zaus ntawm 1.3GHz thiab 13.2GHz, tag nrho yog 1250MHz ntawm cov peev txheej spectrum, los txhawb kev txhim kho cov lag luam 5G network.

Yav Tom Ntej Kev Xav Tau:

Nrog rau kev loj hlob sai ntawm cov thev naus laus zis sib txuas lus wireless, qhov kev xav tau rau cov peev txheej spectrum tab tom loj hlob. Tsoomfwv thiab cov koom haum cuam tshuam tab tom kho cov tswv yim faib spectrum kom tau raws li qhov xav tau ntawm cov thev naus laus zis tshiab thiab cov kev pabcuam. Ua ib qho spectrum nruab nrab, 1250MHz band muaj cov yam ntxwv zoo ntawm kev nthuav dav thiab tej zaum yuav siv tau rau ntau qhov chaw yav tom ntej.

Hauv kev xaus lus, 1250MHz band tam sim no feem ntau siv rau hauv kev sib txuas lus satellite thiab navigation systems. Nrog rau kev txhim kho ntawm thev naus laus zis thiab kev hloov kho ntawm cov cai tswj spectrum, qhov kev siv ntawm band no yuav raug nthuav dav ntxiv.
