So far, German authorities can only notify mobile phones of an impending disaster if their owners have registered beforehand. Soon it will be possible to warn all phones within a certain radius. It is questionable who will decide whether to send such a message.
The German government is another step closer to introducing the „Cell Broadcast“ warning system. Yesterday, the Federal Cabinet agreed on a „formulation aid“ to amend the Telecommunications Act (TKG). If it is passed by the Bundestag, all mobile phones that are logged into a certain mobile phone cell can be warned of an impending event with a text message. The system is not tied to specific phone numbers, but the reception of „cell broadcast“ messages must be activated manually on some mobile phones.
The standard of „Cell Broadcast“ is defined by the 3rd Generation Partnership Project (3GPP), in which worldwide standardisation bodies have joined forces. Accordingly, the service, which was initially only available in GSM networks, can now also be used with LTE and 5G. „Cell Broadcast“ messages can only comprise a maximum of 93 characters. The latest specification extends this to 1,395 characters by sending a total of 15 continuous messages of 93 characters. In addition, the mobile phone emits an alarm tone and vibrates even if it is muted. „Germany: Further step towards the introduction of „Cell Broadcast““ weiterlesen
