sDAS series is TSI’s (DAS) product. The sDAS offers the industry leading and most innovative technology to help mobile operator extend the RF signal coverage into any indoor environment from small to large scale. Indoor network becomes manageable services and new business model.
A sDAS system includes the HEU and RAU. The HEU can take RF signal from any source like Macro/Pico/Femto/Repeater/Small Cell and transport the signal to RAUs in different locations via single fiber. Single HEU can convert and transport the RF signal to max six RAUs within 5km distance. Both star and daisy chain topology are supported

Key Features: Applications:
• Source/Technology independent
• Single fiber for MIMO
• Daisy chain & hybrid topology
• Optics/RF Auto-calibration
• Single-band multi-operator support
• RoHS compliant
• Indoor coverage
• Tunnel coverage
• Rural area signal extension
• Shadow area signal enhancement
