Uhf Radio Repeater 400MHz Bi-Directional Amplifier (BDA) Tetra UHF Channel Selection Signal Repeater Booster sistimi e etselitsoe ho rarolla mathata a lets'oao le fokolang la mohala, le theko e tlase haholo ho feta ho eketsa Base Station (BTS).Ts'ebetso ea mantlha ea sistimi ea RF Repeaters ke ho amohela lets'oao la matla a tlase ho tsoa ho BTS ka phetisetso ea maqhubu a seea-le-moea ebe o fetisetsa lets'oao le holisitsoeng libakeng tseo marang-rang a sa lekaneng.'Me lets'oao la mohala le lona le holisitsoe mme le fetisetsoa ho BTS ka tsela e fapaneng.
Likarolo tse ka Sehloohong
◇ E lumellana le TETRA, TETRAPOL, P25 (Ph1 le Ph2)
◇ High linearity PA, High tsamaiso phaello, Intelligent ALC theknoloji
◇ Duplex e felletseng le ho itšehla thajana ho tloha holimo ho ea ho downlink;
◇ Tlhahlobo ea Auto, Opereishene ea Othomathike e bonolo;
◇ Taolo e feto-fetohang ea mosebelisi, UL le DL e ikemetseng, mocha ka mong;
◇ Tlhokomelo ea lehae le e hole (ka boikhethelo) e nang le alamo ea phoso ea othomathiki &taolo ea remoutu; protocol ea SNMP (ka boikhethelo).
◇ Moralo oa IP67/NEMA4X o thibelang boemo ba leholimo bakeng sa ho kenya maemo a leholimo kaofela.
