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.
