For the delivery of public warning, there appears to be no single solution that fits all of the requirements for the timely notification of an emergency incident or situation. Therefore, a Public Warning System (PWS) ought to be a blend of the best attributes of all of the existing technologies, adapted to the particular demands of the country or territory in question.

This document presents an investigation of the various technologies that are available for public warning, and enables comparison between the various technologies in use today and of those being considered, through initiatives in many countries, for deployment in next generation PWS.

This document also identifies standards involved in the delivery of PWS, such as the developmental ISO 22322 – societal security and emergency management, and ETSI TS 102 182, which reinforces the message that none of the technologies fulfils all requirements. The document also provides examples of PWS implementations in diverse countries, identifies several next generation PWS technologies, such as Hbb TV, and discusses the Universal Service Directive3 call for a pan-European ‘reverse 112 system’.

EENA would like to thank Mr. Peter Sanders, EENA Operations Committee Vice-Chair, and Mr. David Williams, EENA Technical Committee Vice-Chair for their contribution to this publication.
