3g modem teeb liab amplification yuav pom tau hais nrog ib tug tshwj xeeb 3G kav hlau txais xov, uas yog tshwj xeeb uas tsim rau 3G tes hauj lwm, uas yog, ua hauj lwm rau peb txoj kev frequencies.

Thaum yuav xws li ib kav hlau txais xov uas koj yuav tsum kos koj zoo xav txog tej parameter raws li lub nce, raws li zoo raws li lub tawg qauv. Nco ntsoov tias tus loj dua cov ratio, lub narrower daim ntawv.
