What’s the difference between Public Safety DAS and Cellular DAS?

A Public Safety DAS (or BDA) improves radio coverage for first responders and is required by code. A Cellular DAS enhances commercial carrier signals (AT&T, Verizon, T-Mobile, etc.) to improve everyday wireless use for staff and visitors. Many facilities install both systems to ensure reliable communication for emergencies and operations.

Do I need a Public Safety DAS or BDA system to meet fire code requirements?

Most jurisdictions now require buildings to provide adequate Emergency Responder Radio Coverage (ERRC) to pass inspection. If your facility has dead zones or fails the AHJ’s radio signal test, you’ll need a Public Safety DAS/BDA system to achieve compliance with NFPA 72, NFPA 1221, and IFC standards.

How long does it take to design and install a DAS system?

Project timelines vary depending on building size, construction type, carrier approvals, and AHJ requirements. Most Public Safety DAS projects take 6–12 weeks from evaluation to final testing. Cellular DAS systems can take slightly longer due to carrier coordination . Sterling manages the full process spanning assessment, engineering, permitting, installation, testing, and commissioning.
