China Kingtone e fana ka Litšenyehelo tse Atlehang tsa Tšireletseho ea Sechaba TETRA, iDEN 800 MHz Band Frequency 806-821/851-866 MHz Repeater BDA Bi-Directional Amplifier bakeng sa Puisano e Bohlokoa.
TETRA 800MHz +33dBm Off-air Bi-Directional Amplifier(BDA) 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 phetiso ea maqhubu a seea-le-moea ebe o fetisetsa lets'oao le matlafalitsoeng 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.
Ka sehloohong Likaroloana
◇ High linearity PA;Phaello e phahameng ea sistimi;
◇ Theknoloji e bohlale ea ALC;
◇ Duplex e felletseng le ho itšehla thajana ho tloha holimo ho ea ho downlink;
◇ Opereishene e ikemetseng e bonolo;
◇ Mokhoa o kopaneng o nang le ts'ebetso e tšepahalang;
◇ Tlhokomelo ea lehae le e hole (ho ikhethela) ka alamo ea phoso e ikemetseng le taolo ea hole;
◇ Moralo o thibelang boemo ba leholimo bakeng sa ho kenya maemo a leholimo kaofela;
