I-China Kingtone inikeza i-TETRA Yokuphepha Komphakathi Esebenza Ngezindleko, i-iDEN 800 MHz Band Frequency 806-821/851-866 MHz Repeater BDA Bi-Directional Amplifier Yokuxhumana Okubalulekile.
I-TETRA 800MHz +33dBm Off-air Bi-Directional Amplifier(BDA) uhlelo luklanyelwe ukuxazulula izinkinga zesignali yeselula ebuthaka, eshibhe kakhulu kunokwengeza Isiteshi Sokusekela esisha (i-BTS).Ukusebenza okuyinhloko kohlelo lwe-RF Repeaters ukuthola isignali yamandla aphansi evela ku-BTS ngokusakazwa kwamafrikhwensi omsakazo bese idlulisela isignali ekhulisiwe ezindaweni lapho ukutholakala kwenethiwekhi kungenele.Futhi isignali yeselula nayo iyakhuliswa futhi idluliselwe ku-BTS ngendlela ehlukile.
Okuyinhloko Izici
◇ I-PA ephezulu yomugqa;Ukuzuza kwesistimu ephezulu;
◇ Intelligent ALC ubuchwepheshe;
◇ I-duplex egcwele kanye nokuhlukaniswa okuphezulu kusuka ku-uplink kuya ku-downlink;
◇ Ukusebenza okuzenzakalelayo ukusebenza okulula;
◇ Isu elihlanganisiwe elinokusebenza okuthembekile;
◇ Ukuqapha kwendawo nokukude (ongakukhetha) nge-alamu yephutha elizenzakalelayo &isilawuli kude;
◇ Idizayini evikela isimo sezulu yokufakwa kwesimo sezulu sonke;
Uhlelo lokusebenza olujwayelekile:
Kwangaphakathi kwesakhiwo amanethiwekhi angenawaya angenantambo abanzi iDEN Repeater 800MHz (806-821MHz / 851-866MHz ) Isikhulisi Esiphindaphindayo se-BDA
ukwandisa ukumbozwa kwesignali yezindawo eziyimpumputhe lapho isignali ibuthaka noma ingatholakali khona.
1. Ibhilidi elincanyana elifakwe ngaphakathi endlini
2. Ukufakwa kwesakhiwo esiphezulu
3. Ukumboza komhubhe
4. Indlela ehamba ngaphansi komhlaba
5. Ukumboza imoto
6.igumbi elingaphansi
