Welcome to a special episode of DAS Talk, presented by DAS University and hosted by Peter (VP of Gamma Electronics). This time, we’re on-site at Motorola’s Fort Lauderdale headquarters for a powerful roundtable conversation with Rich Jimenez (Motorola Solutions) and Rick Rausch (Gamma Electronics). In this extended discussion, we dive into one of the most critical issues in the world of in-building communications: how to properly design, deploy, and maintain BDAs (Bi-Directional Amplifiers) and Public Safety DAS systems without creating interference or compromising the macro network. What you’ll learn in this episode: • Why “doing BDAs right” matters for public safety—and what happens when they’re done wrong. • Real-world case studies: dual BDA installs causing cross-oscillation, uplink noise, and control channel failures. • The importance of 20 dB isolation above system gain and how to prevent oscillation feedback. • The dangers of the “more power is better” myth—and how it raises the noise floor for entire jurisdictions. • How uplink commissioning works and why it’s the most overlooked (yet critical) step. • Campus solutions: one head end with fiber-fed remotes vs. multiple competing BDAs. • How Motorola became manufacturer-agnostic and works with partners nationwide to ensure systems are clean and reliable. • The role of training for every stakeholder: AHJs, inspectors, integrators, installers, and radio network managers. • A look into P25 technology improvements and why jurisdictions are expanding acceptable RSSI thresholds (from -95 down to -102 dBm). This conversation is technical, detailed, and packed with lessons for integrators, AHJs, engineers, and first responder agencies navigating the future of ERRCS. DAS Talk is your source for bridging the gap between technology, safety, and communication. Stay tuned for more episodes as we continue bringing you insights from the leaders shaping the future of in-building public safety communications.

This episode is a must-watch for fire marshals, AHJs, DAS integrators, code officials, builders, and public safety professionals who want to better understand how communication systems impact tactical response—and how to build stronger partnerships between the industry and enforcement.

This episode is presented in collaboration with the All Clear Podcast, hosted by Concord Fire Department, focused on firefighter wellness, public safety education, and operational readiness.

Key Topics Covered:

• How ERCES systems directly impact first responder survivability

• The dangers of radio “dead zones” in warehouses, high-rises, and new developments

• Why code enforcement officers must understand their authority to require these systems

• Common issues with ERCES maintenance and testing

• Practical collaboration tips for integrators and AHJs

• Real-life case studies from the field in North Carolina

• How Concord Fire Department uses ERCES mapping to improve emergency response

• What every jurisdiction should know to ensure safe and code-compliant coverage

In this episode of DAS Talk, hosts Philip Nicholas Juan and Gilbert Martinez have an in-depth conversation with Chris Cisco of Bearcom, a leading RF DAS engineer. Chris shares his powerful story of transitioning from military communications into the world of distributed antenna systems (DAS) and emergency responder communication enhancement systems (ERCES).

Throughout the discussion, Chris explains why strong in-building communication is absolutely critical for public safety, first responders, and everyday operations. He breaks down how his military background built the foundation for his approach to solving RF engineering challenges in civilian environments.

The episode highlights the urgent need to improve communication systems in schools, where many campuses still dangerously lack reliable radio and cellular coverage. Chris emphasizes how this gap poses major risks during emergencies and shares his experiences working with school districts to solve these problems.

Philip, Gilbert, and Chris also talk about the challenges faced by AHJs (Authorities Having Jurisdiction) in understanding and enforcing DAS requirements. Many AHJs are still learning about these systems themselves, which creates both opportunities and obstacles for the industry.

The conversation stresses the importance of community networking, ongoing education, and mentorship. Chris shares how he built his career largely by seeking out knowledge, forming the right connections, and committing to self-education when formal resources were limited.

This episode covers the real-world problems that DAS professionals encounter daily, from poor building assessments to improperly conducted grid tests. Chris also shares the critical role integrity and best practices must play in the future growth of the DAS industry.

If you are involved in DAS, RF engineering, public safety, or in-building communication, this episode is a must-watch. It delivers valuable insight into both the technical and human sides of the industry, while offering real advice on how we can make schools, hospitals, and public spaces safer for everyone.
