Intersec: Public Warning, decoded
by Intersec
Myth #11: Cell Broadcast alerts are too intrusive
About this podcast
Public warning systems are full of misconceptions. At Intersec, we have spent years implementing these systems across the world, and we have repeatedly heard that they are "too expensive," "too complex," or "too intrusive." Every situation is different, every country brings its own constraints, and every deployment teaches us something new.
This series is our way of sharing that experience, and setting the record straight. One misconception at a time. Short, factual, and built for professionals working in emergency management, telecoms, and public safety.
