SJM Industrial Radio can engineer and design a custom in building solution for your building, facility or campus.

Digital Signal Booster-613-8-series

Also knows as “Signal Boosters”, Bi-Directional Amplifiers (BDA) or Distributed Antenna Systems (DAS), these solutions bring wireless signals from outside your structure, amplify the signal and then evenly distribute that signal throughout the structure. These solutions are complex and require proper engineering design, analysis and installation in order to make them work correctly and efficiently for your specific situation.

These systems can be engineered specifically to fit any type of building where enhanced coverage and communication is needed. Common applications we see are:

  • Hospitals
  • Underground Structures (such as parking garages and basements of buildings)
  • Sports Stadiums & Arenas
  • Shopping Malls
  • Airports
  • Convention Centers
  • Manufacturing Plants
  • Schools and University Campuses
  • Large Buildings

Our in building solutions include:

  • Repeaters
  • Signal Boosters
  • Bi-directional Amplifiers
  • Combiners
  • Filters
  • Duplexers
