Hloov siab heev yog International Telecommunication Union tsim rau pawg xov tooj cua zaus hauv electromagnetic spectrum ntawm 30 txog 300 gigahertz. Nws nyob nruab nrab ntawm lub siab zaus band thiab deb infrared band, qhov qis ntawm uas yog terahertz band.
5G mmWave yog dab tsi?
5G siab bands (mmWave, tseem hu ua FR2) muaj nyob rau hauv ntau ntawm 24GHz txog 40GHz. Lawv xa cov spectrum ntau thiab muaj peev xwm hla qhov luv tshaj plaws. Lawv kuj siv MIMO loj heev los nthuav dav thiab nthuav dav.
Vim li cas thiaj hu ua mmWave?
Cov kab hluav taws xob siab no feem ntau hu ua "mmWave" vim rau luv wavelengths uas ntsuas tau hauv millimeters. Txawm hais tias mmWave bands txuas ntxiv mus txog 300 GHz, nws yog cov bands ntawm 24 GHz mus txog 100 GHz uas xav kom siv rau 5G.
mmWave sawv cev rau dab tsi?
millimeter wave (MM nthwv dej), tseem hu ua millimeter band, yog band ntawm spectrum nrog wavelengths ntawm 10 millimeters (30 GHz) thiab 1 millimeter (300 GHz). Nws tseem yog lub npe hu ua lub suab nrov heev (EHF) band los ntawm International Telecommunication Union (ITU).
millimeter wave technology yog dab tsi?
Millimeter nthwv dej, tseem hu ua qhov zaus siab heev (EHF), yog ib pawg ntawm xov tooj cua zausuas haum rau 5G tes hauj lwm. Piv rau cov zaus hauv qab 5 GHz yav dhau los siv los ntawm cov khoom siv txawb, millimeter yoj thev naus laus zis tso cai rau kev sib kis ntawm cov zaus ntawm 30 GHz thiab 300 GHz.
