I-China Kingtone B2+B5 isiginali yeamplifier 4g dual band 850/1900 gsm pcs 2g 3g amandla elanga aphindaphindayo 5W,10W,20W cdma pcs cellphone booster isignali yakhelwe ukuxazulula izinkinga zesiginali yeselula ye-wak, eshibhe kakhulu kunokwengeza isiteshi esisha sesisekelo. (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.
Uhlelo lwe-Apple: shayela : *3001#12345#* ,amandla esiginali azovela ekhoneni eliphezulu kwesokunxele.
Isistimu ye-Samsung : shayela : *#0011#
Noma ungalanda uhlelo lokusebenza lwe-“LTE Discovery” ukuze uhlole .
Beka ifoni yakho lapho ukuze uhlole amandla ayo esignali ngaphandle:
Android : setting→mayelana nefoni→isimo→inethiwekhi ,dbm isibonisi sizoba kokuthi -75dbm kuya -85dbm nxazonke;
Ama-Dual-band Customized Frequencies ukuze uthole isithenjwa sakho, khetha amabhendi angu-2:
I-B1 (2100) iyibhendi 1 ku-2100 MHz.
I-B2 (1900) iyi-Band 2 ku-1900 MHz.
