Tuam Tshoj Kingtone B2 + B5 teeb liab amplifier 4g dual band 850/1900 gsm pcs 2g 3g hnub ci zog repeater 5W, 10W, 20W cdma pcs cellphone signal booster yog tsim los daws cov teeb meem ntawm wak mobile teeb liab, uas yog ntau pheej yig dua ntxiv lub hauv paus chaw nres tsheb tshiab (BTS). Lub luag haujlwm tseem ceeb ntawm cov repeaters yog kom tau txais cov teeb liab qis zog los ntawm BTS ntawm RF kis tau tus mob thiab tom qab ntawd xa cov teeb liab amplified mus rau thaj chaw uas cov kev pab them nqi network tsis txaus. rov qab kev taw qhia.
Apple system: hu rau: * 3001 # 12345 # * , lub teeb liab lub zog yuav qhia nyob rau sab laug ces kaum.
Samsung system: hu rau: *#0011#
Lossis koj tuaj yeem rub tawm "LTE Discovery" app los kuaj .
Muab koj lub xov tooj nyob rau ntawd los xyuas nws cov teeb liab zog sab nraud:
Android: teeb tsa → hais txog xov tooj → xwm txheej → network, dbm zaub yuav tsum nyob ntawm -75dbm rau -85dbm ib ncig;
Dual-band Customized Frequencies rau koj siv, xaiv 2-bands:
B1 (2100) yog Band 1 ntawm 2100 MHz.
B2 (1900) yog Band 2 ntawm 1900 MHz.
B3 (1800) yog Band 3 ntawm 1800 MHz.
B4 (AWS) is band 4 on AWS 1700/2100MHz.
B5 (850) yog band 5 ntawm 850 MHz.
B7 (2600) yog Band 7 ntawm 2600 MHz.
B8 (900) yog Band 8 ntawm 900 MHz.
B20 (800) yog Band20 ntawm 800MHz
