Uhf Radio Repeater 400MHz Bi-Directional Amplifier (BDA) Tetra UHF Channel Selective Signal Repeater Booster system ua mamanuina e foia ai faafitauli o le vaivai telefoni feaveai, lea e sili atu le taugofie nai lo le faaopoopoina o se Base Station fou (BTS).O le fa'agaioiga autu o le RF Repeaters system o le mauaina lea o le fa'ailo maualalo mai le BTS e ala i le leitio fa'asalalau ona fa'asalalau atu lea o le fa'ailoga fa'ateleina i nofoaga e le lava le fa'aogaina o feso'otaiga.Ma o le telefoni feaveaʻi e faʻateleina foi ma tuʻuina atu i le BTS e ala i le isi itu.
Vaega Autu
◇ E fetaui ma TETRA, TETRAPOL, P25 (Ph1 ma Ph2)
◇ High linearity PA, maualuga faiga maua, atamai ALC tekinolosi
◇ Full duplex ma maualuga vavae ese mai luga i lalo i lalo;
◇ fa'ata'ita'i fa'apitoa, fa'agaioiga otometi fa'agaioiga;
◇ Faʻatonuina le faʻaogaina o tupe maua, UL ma DL tutoatasi, i le alalaupapa;
◇ Mata'ituina fa'apitonu'u ma mamao (filifiliga) fa'atasi ai ma fa'ailo fa'aletonu otometi & fa'atonu mamao; SNMP protocol (filifiliga) .
◇ IP67/NEMA4X Fuafuaga e puipuia le tau mo le faʻapipiʻiina o tau uma.
