Warning channels

What warning channels are used to transmit warning and information messages to the population?

The government’s strategy for warning and informing the population is based on a multi-channel approach that aims to maximize the territorial coverage of message reception and to reach as many people as possible. To this end, and depending on the situation, warning and information messages can be transmitted via the following warning channels:

  • “LU-Alert” mobile application;
  • location-based SMS (LB-SMS);
  • Cell Broadcast (CB);
  • Government websites (e.g. lu-alert.lu, meteolux.lu, inondations.lu, data.public.lu);
  • Press: Radio, television, websites and mobile applications;
  • Social media;
  • Sirens (currently only used in the event of a nuclear alert).

The multiplication and diversity of warning channels ensure that an alert reaches as many people as possible.

What is the difference between Cell Broadcast and location-based SMS?

The transmission of warning and information messages via Cell Broadcast (CB) works in the same way as the sending of location-based SMS (LB-SMS), except that transmission is carried out over a dedicated telecommunication network.
