DIGITAL MASTER UNIT PUBLIC SAFETY CENTRIC DAS SYSTEM (136 - 869MHz)

Manufacturer: Fiplex Warranty: 12 month(s) Stock: Available The Fiplex Digital Master is a RF-to-Fiber and Fiber-to-RF conversion system. These conversions are done using FPGA based Digital Signal Processing. It provides a connection to the Base Station and it centralizes all the connectivity of the DAS.
Order: DIGITAL MASTER UNIT PUBLIC SAFETY CENTRIC DAS SYSTEM (136 - 869MHz)


Features


 

  • DAS Specially designed for LMR and Public Safety Applications
  • Field expandable
  • No need of “Front End BDA” or “POI”, reduced infrastructure cost
  • Programmable uplink squelch (per channel and time slot) for reduced UL noise contribution
  • Software programmable channel selective or band selective operation, suitable for highly congested RF environments
  • Centralized operation, single point of access
  • AGC per channel and time slot, no Far End communication Degradation
  • Same unit supports Over The Air (OTA) operation
  • NFPA Compliant
