sDAS series is a fiber Distribution Antenna
System. The sDAS offers the industry leading
and most innovative technology to help
mobile operator extend the RF signal
coverage into any indoor/outdoor
environment from small to large scale. Indoor
/outdoor coverage network becomes a
manageable services and a new business
The sDAS system includes the HEU and RAU. The HEU can take RF signal from any
source like Macro/Pico/Repeater/Small Cell and distribute the signal to RAUs in
different locations via the single fiber. Each HEU can convert and distribute the RF
signal to max. six RAUs to 5km distance. Both star and daisy chain topology are

Key Features: Applications:
• Distribute the RF signal via a fiber network
• Source/Technology independent
• Star & Daisy chain hybrid topology
• Optics/RF Auto-calibration
• Multi-Carrier
• RoHS compliant
• Indoor coverage
• Tunnel coverage
• Rural area signal extension
• Shadow area signal enhancement
