CMA - Critical Messaging Association

The Critical Messaging Association is the industry association for companies that are dedicated to the wireless delivery of time-sensitive, critical messages. CMA members consist of network operators, manufacturers and others that combine to deliver reliable, point-to-multi-point simulcast technology and integrated messaging solutions for critical and non-critical communications. The mission of the CMA is to advance the industry to ensure world-wide growth by:

  • Providing a forum for industry participants to exchange ideas, technology, and explore new business opportunities;
  • Advocating for favourable regulatory policies;
  • Developing, promoting, and administering technology-related standards;
  • Creating a unified global voice for the critical messaging industry.

The CMA was originally the European Mobile Messaging Association (EMMA). In October 2012 the CMA formed an alliance with the US based Critical Messaging Association so that both organizations could work together to promote their ideals throughout the world.

CMA welcomes anyone involved in the critical messaging industry in Europe or Asia to join.

Industry Usage

From its initial use as a method to alerting doctors attending emergencies, Paging has evolved significantly and is now utilised by a variety of different industry sectors that need to send information rapidly, reliably and cost effectively. From emergency services to Government bodies to blue chip organisations, millions of paging messages are transmitted globally each day to ensure public safety, emergency escalation and business continuity.

Satellite-based and fully redundant high-performance alerting network for LEBIG, AT

Other Sectors

Maximum reliability and failure safety – those were the main criteria that the Leitstellen-Entwicklungs-, Betriebs- und Integrationsgesellschaft (LEBIG) placed on a new alerting network. In 2004 Swissphone was chosen as the technology partner and as supplier for the corresponding system technique. Among Swissphone’s tasks were: the development and installation of a customer-specific paging network with 79 base stations for the federal state of Lower Austria as well as its linkup to the operations control system of the customer and to the satellite-based radio paging/paging centre. Since 2005 LEBIG alerts in Lower Aus-tria, Vienna and in parts of Burgenland only over a satellite-based and fully redundant high-performance Swissphone alerting network.

Currently alerted over this paging network in Lower Austria are the Red Cross task forces and resources, the Arbeitersamariterbund (Workers' Samaritan Federation), the Knights of St. John stationed in Lower Austria, the eastern emergency doctor's helicopter of the air rescue of the Austrian "Automobil-, Motorrad- und Touring-Clubs" (automobile, motorcycle and touring club), the search and rescue dogs of Lower Austria and in some cases the Lower Austrian Lifeguards, the first responder doctors and the senior management for major loss incidents.

On their homepage LEBIG writes that the great advantage of the paging network is not only the nationwide exactly simultaneous and consequently very rapid alarm transmission even to a large number of receivers, but also that the receivers can move around freely in the entire federal state and no longer have to be within the radius of their own ringer.

Emergency Alert System for Extreme Weather Conditions

Local Authorities

Storms and extreme temperatures are ever more frequent the Mid European latitudes. According to statistics, twice as many natural disasters occurred in Germany in the last ten years compared to previous decades and these catastrophes cause casualties and millions of euros of damage. The problem is: how to alert the public in due time in case of storm, tempest or flood? This is particularly difficult at night or in case of power blackout.

e*Message have introduced a novel “storm siren” which provides nation-wide coverage for warning the public rapidly and efficiently in case of imminent local, regional or national disaster.

The technology uses a low-cost module with low power consumption (e*WM) that can be integrated into nearly every electronic device to make it an “intelligent siren”. The alert message is acoustic, alphanumeric or transferred to another device for further processing. The new warning module requires no SIM card and is totally independent from telephone networks. Moreover, it is distinctively more precise, flexible and efficient than conventional sirens. The technology uses e*Message’s satellite-based data broadcast network with nation-wide coverage and thus remains operational even under extreme conditions.


Technical Committee

The Technical Committee is a volunteer committee comprised of industry representatives who ensure the timely development of technologies and standards necessary to support the continued growth of the critical messaging business. These efforts are aimed to increase the capacity and efficiency of network operations and to support the wireless messaging industry in the establishment and provisioning of new and advanced services such as telemetry, internet, and data applications.
