Early warning & public alerts (EWS/PWS)

public safety

100% of the population

It takes more than a text to keep people safe. To maximize the reach and effectiveness of the early warning services, Intersec offers a resolutely multi-channel and specialized software suite for early warning, emergency alerts, and crisis management requirements. 

It addresses the specific needs of various public authorities, telecommunication operators, and mission-critical organizations involved in the global early warning and public warning architecture at a national, regional, or local scale, in due respect to data privacy regulations. Our public warning solutions cover 30% of the population in the European Union.

400M people covered

Our EWS/PWS solutions cover 400 million people worldwide. Intersec is also leading EU provider with public alerting systems deployed in France, Germany, Croatia, Luxembourg, Portugal, Austria... mostly combining Cell Broadcast and Location-Based SMS to stay ahead of the crisis management curve.

Real-time location data

Take up any types of challenges and expectations in a MHEWS (Multi Hazard Early Warning Systems) implementation. Integrating location-specific data streams in this control room system offers crisis management staff a 360° view of the situation.

Multichannel approach

Our EWS/PWS incorporates high-speed messaging, location intelligence, and AI algorithms to ensure efficient communication and real-time effectiveness measurement. Resolutely multichannel, our emergency alert system can seamlessly adapt to various communication infrastructures, including but not limited to telecom networks.

For all public safety stakeholders

Mobile network operators (MNO)


MNOs' infrastructures and modern technologies make it possible to reach 100% of the population. Intersec offers a multichannel, end-to-end and modular approach of national public warning architecture combining Cell Broadcast, location-based SMS, advanced analytics, and AI features, maxiziming the potential of telco data. 

Intersec PWS helps mobile carriers to perfectly meet early warning, public warning and emergency alert requirements of the country.  As a comprehensive and scalable unified product, it facilitates mobile carrier deployment phases, and eases day-to-day activities to keep service always operational.

Public authorities & agencies


The Intersec public warning solution enables the authorities to leverage emerging technologies to detect and respond to incidents and critical events as they arise. It delivers cutting-edge tools such as density heatmaps, automatic selection of the appropriate communication channels depending on circumstances, in-app notifications, sirens and retargeting of populations in case of emergency alerts. 

The Intersec Crisis Management Portal fully meets, and even exceeds, requirements enacted by the European Electronic Communications Code (EECC).  Article 110 mandates EU countries to operate a public warning system that can send geo-targeted emergency alerts to all mobile phones located in the affected area during a natural or man-made disaster, via Cell Broadcast, Location-Based SMS, as well as all legacy and new digital diverse communication channels (outdoor sirens, TV/radio, DAB+, websites, social media, OOH display, GNSS…)

Local authorities & communities


As a complement to the Intersec crisis management portal, Intersec has designed Trela to enable all those involved in emergency alerts to exercise their duty to alert those under their responsibility more effectively, using additional communication channels, integrating specific mapping, taking account of citizens' preferences and habits, etc.

Emergency alerts deserve 100% attention. With Trela, they can leverage 100% of digital channels: SMS, emails, mobile app, website, phone calls, social media, and digital signage.

In a few clicks, entitled users can send an alert to all subscribers in their municipality or territory and mobilize stakeholders to manage and resolve the situation.

Mission-critical organizations


Disruptive events such as health hazards, extreme weather, or even supply chain disturbances can impact business continuity. The Intersec solution allows crisis management teams to keep control and monitor recovery progress in real-time, ensuring response plans get appropriately executed.

Dedicated users can monitor recovery progress in real time thanks to customized dashboards and alert messages, allowing for flexibility to adapt to any scenario and ensure plans get executed properly (the use of emergency text message system for instance).

Cell broadcast is not enough

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.

Toward a multichannel approach


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…

Combining these technologies dramatically increases the efficiency of the system, and accelerates nationwide messaging broadcast, while ensuring full interoperability with existing services.

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.
