Distributed Antenna Systems (DAS) & RF Signal Boosters
PSI offers engineered solutions in Bi‑Directional Amplifiers (BDA) and Distributed Antenna Systems (DAS) to strengthen radio-frequency coverage in challenging environments. Our systems improve two-way radio performance in buildings, tunnels, parking structures, transportation hubs, and campuses—ensuring dependable voice and data links for critical operations.
Historically, BDAs emerged as a response to signal dead zones within large buildings and complex structures. These boosters were first used to ensure emergency responder communication could be maintained inside fire-prone or concrete-heavy buildings. As regulatory codes evolved, BDA/DAS systems became essential for life-safety compliance and operational integrity in commercial and industrial settings. Today, their use has expanded beyond public safety to include private radio systems, enhancing signal coverage for campuses, corporate sites, and manufacturing operations using VHF, UHF, or digital LMR systems.
While Bird TX/RX no longer manufactures new BDA systems, PSI maintains legacy support and offers a wide portfolio of active solutions from other leading providers. We specialize in vendor-neutral design and integration to match your performance needs and compliance requirements.
