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.

Welcome back to DAS Talk, the industry podcast dedicated to Distributed Antenna Systems (DAS) and in-building public safety communication. Hosted by Gil Martinez of GAMMA, this episode features a deep-dive conversation with Adam Dutcher of Potter ERCES — a growing force in emergency communication systems. Potter ERCES has emerged as a key player by blending fire alarm expertise with RF innovation. In this episode, Adam walks us through their Guardian BDA product line, training efforts, AHJ collaboration strategies, and the importance of designing reliable systems that truly protect first responders when it matters most. What You’ll Learn: • The evolution of Potter ERCES and their Guardian BDA systems • Class A vs. Class B BDAs and use cases for UHF systems • Challenges AHJs and integrators face under NFPA 1225 • Why simplified installs and strong training programs matter • How Potter ERCES is preparing for fiber and remote solutions • A preview of what they’re bringing to the DAS University Live Summit

In this episode of DAS Talk, Gil from GAMMA steps in to host a powerful conversation with Adam Dunnom (BEST Enterprises) and Andy Major (Mobili-Fi) about real-world DAS implementation strategies, the future of converged wireless networks, and how to better align AHJs, integrators, and building owners. With the DAS University Live Summit coming up August 5–6 in Concord, NC, this episode gives a preview of what BEST and Mobili-Fi will be teaching—including how to tackle system design, budgeting, convergence, and the complex interplay between cellular and public safety DAS. What you’ll learn in this episode: • The truth about working with green integrators—and how to set them up for success • Why experience is everything in DAS and ERCES work • How BEST Enterprises supports projects before, during, and after installation • How Mobili-Fi builds bridges between carriers, integrators, and AHJs • What converged systems mean, and how to do it without compromising public safety • Why wireless is becoming the fifth utility—and what building owners need to know Whether you’re an AHJ, integrator, or just trying to understand the evolving world of in-building wireless, this episode is packed with insights you can use now. DAS University Live Summit — August 5–6 | Concord, NC Join BEST, Mobili-Fi, PCTEL and other top industry leaders for two days of training and real-world networking.
