of the public warning system is equivalent in terms of
coverage and capacity to reach end-users, including those
only temporarily present in the area concerned, taking
utmost account of BEREC guidelines. Public warnings shall be
easy for end-users to receive.

No need for Mobile ID Need for Mobile ID
Repetition No Repetition
Independant of Congestion Dependant/Increases Congestion
Specific User Experience Regular User Experience
Strong Security Poor Security

CELL BROADCAST - Efficiency
▪ CB messages are sent to the radio infrastructure, bypassing
the core, directed to Cells
▪ Millions of mobile users can be notified in few seconds
