TSI Smart Distributed Antenna System (DAS)

Smart/Slim Distributed Antenna System (DAS) is TSI’s new product to help mobile operator extend the RF signal coverage into any indoor environment from small to large scale.  

A Slim DAS system includes the  Head End Unit  (HEU) 
and couple  Remote Access Unit  (RAU).  The HEU can take RF signal 
from any source like Macro, Pico, Femto, Small Cell and transport the signal to RAUs in different locations via one single fiber.
Single HEU can convert and transport the RF signal to maximum six RAUs upto 3 miles distance.  Both star and daisy chain topology are supported.

​TSI's DAS has the advantages of easy installation, auto-calibration, low capital and operating cost, and to support SNMP.

TSI iBwave Design Services
TSI provides design services for indoor and outdoor DAS projects.   We using industry standard design software iBwave to provide simulation analysis to enhance coverage and capacity for different projects ranging from Taiwan Righ Speed Rail, office buildings to wholesale warehouses.  Data from benchmark testing is often used top improve coverage and performance predictions in the designs.   From assistance and support with your designs to complete turn-key design, TSI can provide the solutions you need.

+  In Indonicia, we use 3pcs TSI DAS to replace 14pcs passive DAS MIMO Antennas in a parking lot. 

 Taiwan High Speed Rail (THSR) use TSI DAS solution in tunnels.
