Uncovering specific functionalities of the “Emergency Alert System” within existing patents posed considerable challenges. The broad nature of the concept resulted in a vast amount of literature. Despite examining 2,000 patents, the essential features were scattered across various documents, failing to unify into a single, comprehensive reference.

Turning to research papers provided limited relief, as many relevant papers focused narrowly on state-of-the-art developments that only partially met the criteria. The abundance of potential leads often felt overwhelming, yet none fully matched the necessary requirements.

Alternative strategies were explored without success, and the persistent fragmentation of information continued to impede progress. Finding an exact match of the required functionalities in a unified reference proved increasingly complex.
