The VHF digital channel selective 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 VHF system. And its easy installation and maintenance can help carriers 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.
Feature:
1. Aluminum-Alloy casing with IP65 protection for high resistance to dust, water and corrosion.
2. Software defined filter supporting up to 2 sub-bands adjustable in each frequency band.
3. Linear power amplification to effectively suppress inter-modulation and spurious emission.
4. RJ45 port provides a link to a notebook for local supervision or IP Based NMS(Network Management System) that can remotely supervise repeater's working status and download operational parameters to the repeater Via Ethernet or LAN.
5. Real Time Interference Signal Cancellation (Multi-path Fading, Feed-Back signal)(Optional).
To expand signal coverage or fill signal blind area where communication signal is weak or unavailable.
Outdoor: Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages...
Indoor: Hotels, exhibition centers, basements, shopping malls, offices, parking lots...
