The RF BDA(Bi-Directional) is designed to provide a more cost-effective solution than adding a new Base Transceiver Station (BTS) to improve signal coverage and communication quality in mobile system. And its easy installation and maintenance can help carrier get fast return.
The BDA is working as a relay between the BTS and mobiles. It receives the low-power signal from 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.
Features:
* it to get the sample.
- Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corroding
- Channel-selective function can amplify only the signals transmitted by the customized 2 channels
- Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink
- USB port provides a link to a notebook for local supervision or IP Based NMS (Network Management System) that can remotely supervise BDA's working status and download operational parameters to the BDA Via Ethernet or LAN
