RadSpex was founded with a clear purpose: to provide accurate, independent testing and real-world technical expertise for Emergency Responder Radio Communication Systems (ERRCS/ERCES). With more than a decade of hands-on experience, our background extends far beyond final testing—it began in the field installing these systems and developed into comprehensive RF testing, commissioning, troubleshooting, and system evaluation. For the past six years, we have personally handled the commissioning and turn-up of ERRCS systems and guided them through final AHJ inspection.

Our extensive experience ranges from single-story facilities to complex fiber-connected DAS systems serving multiple buildings, including high-rise buildings, hospitals, major hotels, apartment complexes with underground parking structures, schools, universities, and commercial facilities. We help ensure these critical systems perform as intended when communications matter most, providing the independent verification and technical consulting that emergency responders depend on.
