Overview:
20dBm signal repeater Dual system series are designed for business places indoor coverage solution. Such as the bookstore, the restaurant, the coffee shop, the KTV, the bar, the parking pot, the super market, big office...It can support any two systems of CDMA, EGSM, GSM, DCS, PCS, WCDMA, AWS, LTE.
Using a revolutionary technology that protects the carrier network, the ET-CR20D-F dual system repeater improves indoor cellphone coverage by capturing and repeating the outside signal, bringing it into the building and enhancing it.
This process creates a "Cell Zone" in blind signal area.
Features:
1. Elegant and Compact design
2. Built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals.
3.31dB MGC(Manual gain control) 1dB one step available for both uplink and downlink to adjust the gain value for proper coverage during installation or maintenance.
4. Auto shut off function available for both uplink and downlink to avoid deep self-oscillations from jamming the towers, saving your trouble from operators.
5. Low power consumption.
