I-TETRA 400MHz-450Mhz I-Band Selective Repeater ye-UHF Radio Repeater Bi-Directional Amplifier BDA inikeza ukufakwa okuyisisekelo kwezindawo ezincane nezimaphakathi zasendlini nezangaphandle.I-Band Selective Repeater ikhulisa yonke ibhendi engu-5 MHz TETRA UHF ukuze ixhume phezulu naphansi.Kuyidivayisi ebiza kancane, elula, ethembekile futhi eqinile eqinisekisa futhi ekhulisa ukuxhumana phakathi kwesiteshi sesisekelo se-TETRA/UHF kanye nedivayisi ephathwa ngesandla ye-TETRA.Ukufakwa kuyinqubo elula futhi esheshayo futhi ophindayo usemoyeni kungakapheli imizuzu.Isiphindayo singalungiselelwa kusayithi, noma ukude nge-Kingtone OMT Monitoring Manager Software.
1.BDA (i-Amplifier ye-Bi-directional) imvamisa yokusebenza - ukusuka kububanzi kuye ku-400Mhz ukuya ku-450Mhz.(UHF DMR TETRA)
2.Amandla okukhipha phakathi kwe-watt engu-1, ama-watt angu-2, ama-watt angu-5, ama-watt angu-10 noma ama-watt angu-20.
3.U-Walkie TalkieUmhlinzeki Wesixazululo Sokuhlanganisa I-Signal Extender ye-iCOM, Hytera, Motorola, Kenwood
Izici Eziyinhloko
1,I-PA ephezulu yomugqa;Ukuzuza kwesistimu ephezulu;
2,Intelligent ALC ubuchwepheshe;
3,I-duplex egcwele kanye nokuhlukaniswa okuphezulu ukusuka ekuxhumekeni phezulu kuya phansi;
4,Automatic Operation operation elula;
5,Isu elihlanganisiwe nokusebenza okuthembekile;
6,Umsebenzi oqinile we-OMT/OMCnge-alamu yephutha elizenzakalelayo & nesilawuli kude,ukusebenza okulula nokugcinwa,inketho;
7,Idizayini evikela isimo sezulu yokufakwa kwesimo sezulu sonke;
