Occasionally, stadium security communications will fail during large sporting events and make it impossible for security staff to call for backup or emergency response in dire situations. The problem could be interference in the installed system. However, with over 100 vendors and a dozen other RF systems, finding interference is like looking for a needle in a haystack. Many adjacent agencies could be hunting the same signal at the same time without ever realizing it. This case study discusses how industry collaboration helped meet the challenges of in-building interference detection and mitigation across jurisdictional and corporate boundaries.
