Dab tsi yogLTE Band 31 450MHz Repeater?
LTE450, tseem hu ua band 31, yog ib daim ntawv thov ntiag tug LTE network siv a450MHz zaus.
Long-Term Evolution (LTE) kev sib txuas lus hauv xov tooj siv ntau zaus, Band 31, FDD, 450, NMT, 452.5 - 457.5, 462.5 - 467.5 .
Qhov sib txawv tshaj plaws hauv LTE 450 yog nws qhov tsawg zaus, ntawm 450 MHz.Cov kev sib txuas lus pej xeem muaj zaus ntawm 900, 1800, 2100 lossis 2600 MHz.Qhov zaus ntawm LTE 450, lossis band 31 raws li qee zaum paub, yuav tsum muaj lub siab LTE 450 module.Qhov no tam sim ntawd muab LTE 450 kom zoo dua ntawm cov teeb liab tsawg dua.
LTE 450 nws tus kheej yog kev sib txuas lus wireless raws li 450 MHz zaus.Qhov tseem ceeb tshaj, nws yog lub network band uas muaj qhov dav ncav cuag, sib sib zog nqus teeb liab nkag mus, siab ceev thiab ruaj ntseg, kev sib txuas tau zoo.
Kingtone Muab Tus Nqi Zoo Tshaj Lij Tshaj Lij Tshaj Lij LTE Network Amplifier FDD LTE Band 31 450MHz Sab Nraud Band Xaiv Repeater, txais tos koj nug!
