The TETRA BDA 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 mobile terminals/ walkie talkie. 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 radio network signal is also amplified and retransmitted to the BTS via the opposite direction.
The band-selective function can amplify all signals in the whole band (bandwidth is customized).
Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corrosion
Low interference to BTS by adopting linear amplifier with high gain and low noise
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 to the built-in wireless modem to communicate with the NMS (Network Management System) that can remotely supervise repeater’s working status and download operational parameters to the BDA
To expand signal coverage or fill signal blind area where BTS signal is weak or unavailable. 1. Public Safety 2. Transportation 3. Utilities 4. Government 5. Military 6. PAMR 7. Commercial & Industry 8. Oil & Gas |
