Tri-Band GSM900 & DCS1800 & WCDMA Pico Repeater
Model: KR-1565GDW
Introductions
The Tri-band GSM900&DCS1800&WCDMA Pico Band-Selective Repeater provides an affordable solution to solve the indoor signal coverage problems in both GSM900&DCS1800&WCDMA system due to signal fading and attenuation caused by architecture obstacles. And its easy installation and maintenance can help carrier get fast return.
The repeater is working as a relay between the BTS and mobiles. It picks up the strongest signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Indoor Signal Distribution System to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.
The band-selective function can choose to amplify the signal within the customized band.
Features
n Two signal ports with full duplex design
n High system gain
n Linear power amplification to effectively suppress inter-modulation and spurious emission
n Smart Automatic Level Control (ALC) ensures output level stable and adjustable continuously
n Unique color LEDs to indicate power supply and state and alarm
n Simple installation with external AC/DC adapter
