iDEN BDA
The iDEN is designed to provide a more cost-effective solution than adding a new Base Station (BS) to improve signal coverage and communication quality in iDEN system. And its easy installation and maintenance can help carrier get fast return. The BDA is working as a relay between the BS and mobiles. It receives the low-power signal from BS 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 BS via the opposite direction. The channel-selective function can amplify only the signals transmitted by the customized 1 (2 or 4) channel.
Features
- Aluminum-alloy casing the IP65 protection has high resistance to dust, water and corroding
- No interference to BS by adopting linear amplifier with high grain and low noise
- Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink
- RS-232 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 BDA's working status and download operational parameters to the BDA.
- Highly selective channel selector can process 2 channels simultaneously
Applications To expand signal coverage or enhance signal blind area where iDEN signal is weak or unavailable
- Public safety
- Transportation
- Utilities
- Government
- Military
- PAMR
- Commercial and Industry
- Oil and Gas
