Signal Cellular Repeater Amplifier - SA900A
GSM-EL-SA900A is a Mini Cellular Repeater for GSM cellular signals.
Our GSM Mini Cellular Repeater provides an affordable solution to solve the indoor coverage problems due to signal fading and attenuation caused by architecture obstacles.
The GSM Signal Amplifier is mainly deployed for small points of in-building wireless signal coverage, when installation of standard repeaters will generate great interference to the wireless network or the area to be covered is widely distributed. Its easy installation and maintenance can help carrier get fast return.
The GSM Signal Amplifier works as a relay between the BTS and mobiles. It picks up the strongest signal from the BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Coverage Antenna to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.
