1 Taw qhia
Leaky coaxial cable muaj ob qho chaw ntsuas hluav taws xob thiab cov kav hlau txais xov. Los ntawm kev tswj hwm qhib ntawm tus thawj coj sab nraud, cov kev tswj hwm hluav taws xob tuaj yeem ua rau thaj chaw dig muag thiab tau txais cov laj thawj ntawm hluav taws xob sib txuas lus, thiab ua tiav lub hom phiaj ntawm kev sib txuas lus ruaj khov.
2. Cov ntsiab lus ntim
- Kev sib txuas lus mobile nyob rau hauv cov tuam tsev, ntau thiab subways (GSM, PCN / PCs, dect ...)
- Kev sib txuas lus hauv cov vaj tse nyob hauv av, xws li chaw nres tsheb, hauv paus thiab cov mines
- Kis kis las FM (88-108m) cov ntaub ntawv hauv kev loj hauv kev loj
- Xa mus rau ntawm Wireless Lub tswb Cim hauv Kev Loj Hlob
- Kev sib kis ntawm lub xov tooj txawb xov tooj ntawm txoj kev loj
- Kev xa tawm kis hauv subways lossis subway tunnels
