Product Description
The dual band 1800/2100MHz Pico Repeater provides an affordable solution to solve the indoor signal coverage problems 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.
AGC MGC Function
The AGC and MGC functions can prevent the amplified signal from causing interference to the base station. Even if it is installed incorrectly, the amplifier can protect the normal operation of the base station.
Adjustable Gain
Automatic adjust the system gain to avoid the repeater self-excitation
Check the frequency range before you buy
To make sure that the amplifier you buy is suitable for your mobile operator, please follow the steps and detect the frequency range of your mobile phone. This signal booster can only work on Band 3, Band 1.
Band 8 = B8 = 2G GSM900 / EGSM900
Band 3 = B3 = 4G DCS1800 / 4G LTE1800
Band 1 = B1 = 3G WCDMA2100 / 3G UMTS2100
