Dual Band HEU-1/3_01

sDAS HEU-1/3_01 (Band 1 / Band 3)

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 model.
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 supported.
