I-China 2 watt/5 watt/10 watt/20 watt 900 2100 dual band cell phone repeater/repetidor/booster/amplifier yangaphandle nangaphakathi yakhelwe ukuxazulula izinkinga zesiginali yeselula ye-wak, eshibhe kakhulu kunokwengeza isiteshi esisha esiyisisekelo. (BTS).Ukusebenza okuyinhloko kwabaphindayo ukuthola isignali yamandla aphansi evela ku-BTS ngokudluliswa kwe-RF bese bedlulisela isignali ekhulisiwe ezindaweni lapho ukutholakala kwenethiwekhi kungenele. Futhi isignali yeselula nayo iyakhuliswa futhi idluliselwe ku-BTS nge- isiqondiso esiphambene.
Izici:
1, Amandla Okukhipha +30dBm – +43dBm ngohlelo lokusebenza olukhulu lokuhlanganisa;
2, Inzuzo ephezulu yokusebenza njengeMin.95dB;
3, Ukwamukela isihlungi esinokukhetha kakhulu kanye nokulahlekelwa kokufaka okuphansi kuqeda ukuphazamiseka phakathi kwe-uplink ne-downlink;
Izimbobo ze-4, RS232 zinikeza izixhumanisi zekhompuyutha ephathekayo ukuze zisethwe endaweni kanye nokuqapha ngokubonwa kwewebhu eyakhelwe ngaphakathi;
5, Imodemu engenawaya eyakhelwe ngaphakathi (Inketho) yokuqapha okukude nge-SMS noma i-GPRS;
6,Amapharamitha wokuphindaphinda imininingwane kanye nesimo kungagadwa yi-Control Panel, njengezinga lokushisa, izinga lamandla okukhiphayo, inzuzo, i-ATT, ukulahleka kokubuyisela, i-VSWR njll;
7, Sekela ukuthuthukisa i-firmware ukude nge-GPRS;
8,Indlela yokwenza i-amplifier yamandla aphezulu ezuzisa kakhulu ngokusebenza okuthembekile;
9, Usayizi ohlangene nesisindo esincane, kulula ukukufaka odongeni noma esigxotsheni;
