Gsm900 Car Carrier Repeater Solves Signal Coverage Problems And Telecommunication In Cars
Posted at: TradersCity --> Offers to Sell and Export
Posted on: Wed 20 Aug, 2008 4:08 am
The GSM900 Car carrier Repeater provides an affordable solution to solve the 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 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.
Features:
1. Adopt double-duplex design
2. Communication in car more easily
3. Practical, beautiful and easy to install
