    "body_text": "Mission-critical push-to-talk increasingly rides on commercial broadband, but a crowded event can turn ordinary resource contention into a safety problem. Researchers placed twelve identical smartphones across multiple physical sectors of Texas A&M University's Kyle Field during a football game attended by more than 105,000 people. Automated calls crossed carriers and service types while the team measured connection rates, packet delivery and perceptual audio quality.\n\nThe reported failure was not a gentle decline. Once transport jitter crossed the de-jitter buffer's effective boundary, the voice path developed structural audio loss even though the devices themselves were not the bottleneck. Priority-managed channels bypassed that congestion in the tested setup. The experiment supports dedicated resources and end-to-end prioritization for emergency communications in dense venues; it does not prove that every carrier, stadium or priority configuration will behave the same way.",
