Cov Thawj Coj Tsim Tsim yuav tsum tau siv cua sov ua kom sov, feem ntau siv cov xov tooj tooj liab hnyav, los sis sib xyaw nrog hlau corecbs / lub dab dej kub.
6. Kev ntseeg siab thiab muaj kev ruaj khov
Cov lus piav qhia: Cov laug cam tau siv nyob rau hauv network infrastrastructure xav tau lub sijhawm ntev heev ntawm kev ua tiav (MTBF). Lawv siv cov ntaub ntawv siab siab thiab yauv kev sim ua kom muaj kev cia siab, piv txwv li xa mus rau qhov chaw hnyav thiab ua haujlwm ruaj khov rau ntau xyoo.
7. Kev nruj Electromagnetic Compatibility (EMC)
Cov lus piav qhia: Board -} qib qib tsim nyog yuav tsum txiav txim siab hauv tshuab hluav taws xob (EMC) thiab hluav taws xob sib cuam tshuam (EMI) kev hloov pauv. Los ntawm kev siv cov paib tiv thaiv, lim lim dej, cov qauv hauv av kom tsim nyog, nws txwv tsis pub npaj tawm los ntawm kev cuam tshuam radiating los ntawm kev cuam tshuam radiating thiab tiv thaiv sab nraud cuam tshuam.
Khoom Daim Ntawv Thov Teb
1. Xov tooj cua Nkag Network (khiav)
Cov chaw nres tsheb: suav nrog Macro hlwb, cov hlwb me, thiab muab cov kav hlau txais xov hluav taws xob (DAS). Cov laug cam yuav tsum lis siab- zaus RF cim (piv txwv li 5g Mmwave) rau teeb liab, thiab kev sib sau ua ke / demodulation.
Cov xov tooj cua tej thaj chaw deb (RRUS): Ua tus RF kev ua haujlwm ntawm cov hauv paus chaw nres tsheb; Cov laug cam xav tau zoo heev - zaus kev ua tau zoo thiab kev tswj hwm thermal.
Kav hlau txais xov: Circuit Coalch nyob rau hauv cov kav hlau kav hlau kav hlau txais xov (AAS) rau cov beamforming thiab teeb liab ua.
