5G & LTE Integrated DAS gIRO The gIRO is an integrated DAS that supports CDMA/WCDMA/LTE and 5G 4T4R. Currently commercially operated on SK Telecom network.

Overview

  • 4T4R 5G NR & 4-band LTE-A integrated remote device
  • Digital interface (Private frame, Open CPRI) use and service bandwidth are variable
  • System capable of outdoor installation and in-building distributed antenna network construction
  • CDMA (IS-95A/B, CDMA2000 1X, 1xEV-DO) and LTE service in 800MHz band, LTE service in 1.8GHz band, WCDMA and LTE service in 2.1GHz band, LTE service in 2.6GHz band, LTE service in 3.5GHz band Provide 5G NR service
  • Large output system to expand in-building coverage and increase capacity
  • A system capable of outdoor service in addition to in-building service
  • 5G MIMO support for 5G Throughput increase (2x2 or 4x4 MIMO function support)
  • Multi-band integrated type to reduce installation space constraints and optical line rental costs
  • Band Selectable structure for future LTE frequency bandwidth expansion
  • Center frequency & Band Selectable structure for additional use of 3.5GHz band frequency in the future
gIRO is a member of the cost-effective and highly scalable Mobile Access
