ATIS Developing Requirements for Earthquake Warning System

ATIS said it's developing the North American requirements and high-level architecture specifications for an LTE-based earthquake early warning system (EEWS) on cellular networks. “This effort was spawned in support of California's proposed EEWS and is anticipated to initially focus more broadly on a solution for the west coast of North America,” ATIS said in a news release. “The work will address use cases, end-to-end system requirements and architecture, mobile device behavior requirements, and security considerations. It will also include an analysis of existing standards to determine if additional enhancements may be required.” The FCC recently sought comment on how quickly carriers could transmit warnings (see 1605100054).
