900MHz 1800MHz Dual Band Low Power 2g 3G 4G Signal Booster Repeater Amplifier

Product Description

900&1800MHz Low Power Repeater 2g 3g 4g Signal Booster & Repeater & Amplifier 

What's repeater and how does it work?
Repeater stations (Repeaters) belong to the same frequency amplifying device, refers to play in the process of wireless transmission signal enhanced via a radio transmitting equipment.
The basic function of the repeater station is a power rf signal enhancer.
Repeater stations in downlink link, pick up signals from donor antenna existing coverage, through a band-pass filter with TongWai signal is an excellent isolation, filtering the signal after amplifier amplification again to launch for coverage.
In uplink link path, covering the area of mobile phone signals in the same way of working by uplink amplification of link after launch to the corresponding base stations, so as to achieve the signal transmission of the base station and mobile phones.
