I-KingtoneOphindayos uhlelo lwenzelwe ukuxazulula izinkinga zesiginali yeselula ebuthakathaka, eshibhe kakhulu kunokwengeza Isiteshi esisha Sokusekela (BTS).Ukusebenza okuyinhloko kohlelo lwe-RF Repeaters ukuthola okuphansi-isignali yamandla evela ku-BTS ngokudluliswa kwefrikhwensi yomsakazo bese idlulisela isignali ekhulisiwe ezindaweni lapho ukutholakala kwenethiwekhi kungenele.Futhi isignali yeselula nayo iyakhuliswa futhi idluliselwe ku-BTS ngendlela ehlukile.
- Isici esiyinhloko
-
Izici Eziyinhloko zabaphindayo:
I-PA ephezulu yomugqa;Ukuzuza kwesistimu ephezulu;
Intelligent ALC ubuchwepheshe;
I-duplex ephelele kanye nokuhlukaniswa okuphezulu kusuka ku-uplink kuya ku-downlink;
Automatic Operation operation elula;
Isu elihlanganisiwe nokusebenza okuthembekile;
Ukuqapha kwasendaweni nokukude (ongakukhetha) nge-alamu yephutha elizenzakalelayo &isilawuli kude;
Idizayini evikela isimo sezulu yokufakwa kwesimo sezulu sonke;
- Uhlelo lokusebenza&izimo
-
Izicelo ze-DCS 1800 eziphindayo:
Ukwandisa ukumbozwa kwesignali yendawo eyimpumputhe yesignali yokugcwalisa lapho isignali ibuthakathaka
noma engatholakali.
Ngaphandle: Izikhumulo Zezindiza, Izifunda Zezokuvakasha, Izifundo Zegalofu, Imigudu, Amafekthri, Izifunda Zezimayini, Imizana njll.
Ngaphakathi: Amahhotela, Izikhungo Zemibukiso, Amagumbi angaphansi, Ukuthenga
Izitolo ezinkulu, 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.
