PreAmplifier Cell Phone Range Extender Improve Uplink Power 20dBm
The GREETWIN cell phone booster has been designed to prevent overloading or
interfering with existing networks. Operators have approved the
device to access their networks. It is important to buy a signal
booster that does not interfere with other networks. If not
purchasing from us, please make sure that the signal booster you
are going to buy has been approved by your carrier and have been
proven not to cause network interference.
Pre-amplifier is utilized when the input power of the repeater is
weaker than the suitable power level, pre-amplifier will boost the
input signals to a certain reasonable level, so that the repeater
can reach its full output power for a much larger coverage size.
Pre-amplifier has also been largely deployed to assist the Pico
repeater operation in rural areas. As it is known, the Pico
repeater only gets 5~15dBm output power in UL, so when the repeater
site is too far away from the BTS tower, the mobile phone signals
would not be strong enough to go back. Typical phenomena is that
people can see full bar signals on the mobile phone, but the phone
calls can't be initiated. So a pre-amplifier with 20dBm output
power in UL would increase the UL power level of the repeater so
that the signals can reach BTS tower.
pre-amplifiers are available in single, dual and triple mobile band
, i.e., not only we have pre-amplifier able to amplify one GSM900
band , but also a triple band one to support GSM900, DCS and WCDMA
at the same time.
It supports all current technologies of GSM850, GSM900, DCS, PCS;
CDMA450, CDMA800, CDMA1900, CDMA2000, WCDMA2100 and AWS.
Though it supports up to triple band , the pre-amplifiers are still
compact size, elegantly looking with low power consumption.

PreAmplifier Advantages:
1. can customize the Cover Image on the Cell Phone Signal Booster, design private styles
2. If there are strong input signal or severe self oscillation, ISO
LED is red.
3. If there are good input signal, AGC LED is green.
