Since June 2022, the European Electronic Communications Code (EECC) Article 110 requires all EU countries to operate a public warning system that can send geo-targeted emergency alerts to all mobile users located in the affected area in case of an emergency. 

Progressing on technology transformation, the French Ministry of the Interior, alongside the three major national mobile operators – Orange, Bouygues Telecom, and SFR – selected the Intersec public warning solution to implement a fully integrated alerting architecture for the years to come.


  • 100% coverage of cell phones in use in metropolitan France and French overseas territories (more than 80 million units) 

  • Multi-channel portal combining all alerting media:  Cell Broadcast, Location-Based SMS, sirens, social media, websites… and ready to integrate with Galileo

  • Tactical management of a crisis with real-time population heatmaps, retargeting capabilities, and highly contextualized communications

We were attracted by the completeness of the Intersec solution, by its experience in delivering messages on a very large scale depending on the real-time location of recipients, and by the willingness of its teams to keep this solution at the cutting edge of technology over the years to come.

Romain Moutard

Director of the FR-Alert program


Article 110 of the European Electronic Communications Code (EECC) mandated all EU countries to operate a public warning system that can send geo-targeted emergency alerts to all mobile users located in the affected area in case of an emergency. 

Telefonica O₂ Germany was looking for a partner able to deploy Cell Broadcast technology in a collaborative manner, in full compliance with data privacy regulations, and in alignment with the EECC requirements.


  • As the European Union's leading public warning system provider and with 19 years of experience in the telco industry, Intersec had demonstrated its ability to deploy nationwide public warning systems at Tier-1 operators

  • Intersec partnered with Telefónica Ingeniería de Seguridad (TIS) to ensure seamless and smooth integration in record time

  • On 2022 Nationwide Alert Day – Warntag – Telefonica successfully broadcasted two alert messages - in German and in English – from the Federal Office for Civil Protection and Disaster Relief in just a matter of seconds, confirming the high-end performance of the solution

The high level of expertise and experience of the Intersec professional services team enabled a smooth integration in record time. This success is a testament to the relevance of this partnership, where Intersec's expertise and ours work together in the best possible way.

Cell broadcast and location-based SMS

Why Cell Broadcast?


Cell Broadcast is an instrumental technology when dealing with Early Warning and Emergency Warning in critical or degraded situations, or when time is of the essence.

The alert text message is issued by a Cell Broadcast Entity (CBE) and broadcasted by the Cell Broadcast Center (CBC) to all mobile devices in a defined area. Such short messages (SMS-CB) benefits from a specific display and possibly a notification accompanied by a particular ringtone, to be recognized instantly as an alert.

The Cell Broadcast Service (CBS) is a powerful technology: one may reach millions of devices in a few seconds even if the operators’ networks are congested and in full privacy data protection compliance as the phone numbers of the subscribers are not used in the broadcasting operations.

Why Location-Based SMS?


First of all, SMS channel offers the perfect compatibility level, being supported by 100% of mobile network and phone generations all over the world for 30+ years.

Leveraging on a genuine real-time cellular geolocation technology, public warning via LB-SMS unlocks dynamic and adaptative public warning strategies, to cope with any situation and throughout the crisis management timeline.

This great flexibility is typically expressed in the wide variety of targeting scenarios:

  • address the SMS alert to all subscribers inside or entering the impacted area, optionally add devices that were recently in the zone
  • send distinct SMS content to inbound roamers with specific information in their language
  • alert subscribers roaming abroad of a particular situation there, or in home country
  • recontact people afterwards, even if there are not anymore inside the impacted area, to provide follow-up instructions and situation updates, and return-to-normal or post-event information.

Moreover, thanks again to the SMS technology standard, managing authorities can monitor in real-time the effectiveness of the alert dissemination within the population through aggregated and anonymized delivery statistics.

Which public alerting technologies to use when facing an emergency?


Intersec strongly believes that governments and mobile network operators should adopt a multichannel approach in order to maximize the chances of disseminating information to as many people as possible in case of an emergency. Possible channels include using people’s phones, but also sirens, social media, TVs & radios, emails, variable message signs… The choice to combine certain technologies depends on various factors, including:

  • the nature of the event
  • the number of people to be reached
  • the required speed to communicate
  • the state of the mobile networks
  • etc.

So, which technologies to use when facing a tsunami, flash floods or a dirty bomb for example?  Let's look at some concrete examples in this infographic.
