sDAS+ HEU (Head End Unit)
sDAS+ series is a fiber Distributed Antenna System. The sDAS+ offers the industry leading and most innovative technology to extend the RF signal of public safety band coverage into any indoor/outdoor environment from small to large scale. Indoor /outdoor coverage network becomes a manageable services.
A sDAS+ system includes the HEU and RAU. The HEU can take RF signal from any source like Macro/Pico/Small Cell/BDA and distribute the signal to RAUs in different locations via the single mode fiber. Each HEU can convert and distribute the RF signal to max. eight RAUs to 3 miles distance.
