95dB 43dBm 20W 2g 3g 4g ALC 900 Mhz B8 Ibhendi Elodwa Iselula Ifoni LTE Inethiwekhi Yesiginali Yokukhulisa Isikhulisamsindo Isiphindaphindi Sesiginali
Isistimu ye-Kingtone JIMTOM® Repeaters yakhelwe ukuxazulula izinkinga zesignali yeselula ebuthakathaka, eshibhe kakhulu kunokwengeza Isiteshi esisha Somsuka (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.
Izici Eziyinhloko
1,Ihambisana ne-GSM,UMTS,LTE
2, High linearity PA;Ukuzuza kwesistimu ephezulu;
3, Intelligent ALC ubuchwepheshe;
I-4, Inqubo edidiyelwe ngokusebenza okuthembekile;
5, Ukuqapha kwendawo nge-alamu yephutha elizenzakalelayo &isilawuli kude;
6, Idizayini evikela isimo sezulu yokufakwa kwesimo sezulu sonke;
Izinhlelo zokusebenza
Ukwandisa ukumbozwa kwesignali yendawo eyimpumputhe yesignali yokugcwalisa lapho isignali ibuthaka noma ingatholakali khona.
Ngaphandle: Izikhumulo zezindiza, Izifunda Zezokuvakasha, Izifundo Zegalofu, Imigudu, Izimboni, Izifunda Zezimayini, Imizana njll.
Ngasendlini: Amahhotela, Izikhungo Zemibukiso, Izindlu Ezingaphansi, Izitolo Zokuthenga, Amahhovisi, Izitolo Zokupakisha njll.
Isebenza kakhulu esimweni esinjalo:
Ophindayo angathola indawo yokufaka engathola isignali emsulwa ye-BTS ezingeni eliqinile ngokwanele njengoba Izinga le-Rx kusayithi lokuphinda kufanele libe ngaphezu kuka- -70dBm;
Futhi ingahlangabezana nemfuneko yokuhlukaniswa kwe-antenna ukugwema ukuzizulisa.
