iDEN BDA

|
The iDEN ICS Repeater 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 iDEN system. And its easy installation and maintenance can help carriers get fast return.
The repeater 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
- Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corroding
- Highly selective digital channel selector can process 12 channels simultaneously
- Real Time Interference Signal Cancellation (Multi-path Fading, Feed-Back signal)
- 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 repeater
Application
To expand signal coverage or fill signal blind area where iDEN signal is weak or unavailable.
