SOLiD Products

Coverage solution: DAS

  • DAS for mid-to-large indoor and outdoor: Commercial/Residential Buildings, Stadiums, Subways/Trains, Airports, Hospitals and Campuses
  • SOLiD is No.1 in Korea and No.3 in US market * in terms of no. of DAS nodes deployed
  • References include world famous land marks and major stadiums/subways in 5 continents
  • Enablers to lower TCO model: Multi-operators/technologies/bands support with high reliability and low power consumption

Coverage solution: ICS

  • ICS for suburban/rural, island, cruise ship and small venue in-building
    • Cost benefits over base stations: No need for backhaul, less operation space and easier installation, commissioning & maintenance
  • Solution for a) alternative to fixed broadband and b) customer complaint
    • 'National Broadband Scheme' in an European country: Deployed 25K SOLiD ICS to provide 1+Mbps to 30% undeserved areas in rural, mountain and island area
    • Overall deployment time is shorter than base station and other RF repeaters
  • 3G and 4G ready; Single-band and multi-band ready
  • Solar-cell power option enhances benefits

RAN Implementation Strategy



  • BBU-RRH co-location
  • Met-Eth as backhaul
  • Limited scalability: Backhaul bandwidth dependency


  • BBU concentration
  • PtP fronthaul
  • Huge investment for the fiber plant


  • BBU concentration
  • WDM fronthaul
  • Leverage Met-Eth as a part of fronthaul
