Uhf Radio Repeater 400MHz Bi-Directional Amplifier (BDA) Tetra UHF Channel Nidaamka Kobciyaha Calaamadaha Xulashada waxaa loogu talagalay in lagu xalliyo dhibaatooyinka signalada gacanta daciifka ah, kaas oo aad uga jaban in lagu daro Saldhig cusub (BTS).Hawlgalka ugu weyn ee nidaamka RF Repeaters waa in laga helo signalka tamarta yar ee BTS iyada oo loo marayo gudbinta soo noqnoqda raadiyaha ka dibna u gudbiya signalka la xoojiyay meelaha daboolka shabakadu ku filnayn.Iyo calaamada mobilada sidoo kale waa la xoojiyay oo loo gudbiyaa BTS iyada oo loo sii marayo jihada ka soo horjeeda.
Tilmaamaha ugu muhiimsan
◇ La jaan qaada TETRA, TETRAPOL, P25 (Ph1 iyo Ph2)
◇ Khadka sare ee PA, faa'iido nidaam sare, tignoolajiyada ALC ee caqliga leh
