Repeater

  • Fill the shadow area and extend the coverage in a mobile service network
  • Digital optical repeater connected to BTS via optical fiber and wireless repeater relaying BTS signal wirelessly

Digital Optical Repeater

  • Digital signal processing and optical transmission
  • Minimization of signal quality degradation due to transmission loss
  • Extended transmission range compared to analog optical repeater and versatile transmission mode via multiple sector/selective FA transmission
  • Flexible network design and efficient call volume management
  • Cost reduction in optical infrastructure – 1 BRANCH 2 SECTOR
  • Call distribution control via DCC (dynamic cell control)
  • Systematic management via NMS from a remote site

RF Repeater

  • In-home wireless repeater with built-in input/output antennae
  • Feedback minimization between I/O antennae (show-stopper of existing RF repeaters)
  • Auto-recovery functionality
  • Ready installation (plug & play functionality), allowing flexible deployment
  • Simple maintenance as well as guaranteed reliability

ICS Repeater

  • Outdoor RF repeater with ICS (interference cancellation system)
  • Feedback signal cancellation between donor/coverage antennae
  • Seamless service after minimal installation work for donor antenna
  • Simple maintenance
  • Superb service quality possible at reasonable cost
  • Systematic management via NMS from a remote site

UTP Receiver

  • Digital repeater exploiting UTP cable
  • In-building deployment, typically with donor and remote unit on each floor
  • Flexible network architecture via cascade/multi-drop connection
  • Low installation cost by drawing power via PoE (Power over Ethernet)
  • Simple maintenance
  • Systematic management via NMS from a remote site
