@LaF0rge @stman @kDelta @Sempf obviously that's why it was discontinued for a time in #Germany, as it was considered as obsolete as #HSCSD is in light of faster standards that - even without guaranteed bandwith - will yield higher throughput.

• Obviously #CellBroadcast will necessitate a constant bandwith allocation for functionality as it's design is based upon repeating a message until it's transmissiom being removed.

Still, even in contended #spectrum this is manageable, espechally since most #MNOs only maintain vestigal #2G or #3G infrastructure solely for #emergency coverage and reliability, as most phones will call emergency services over 2G and 3G and not via #VoLTE.

• To add insult to injury, most BSCs will downgrade to 2G-only service by default in case of power loss to maximize UPS range and in the case of #NewZealand even switch off all services but #SMS & #EmergencyServicesCalling to enshure people in need can get their calls out, as the population is instructed to use SMS for person-to-person communication (as SMS is a low-priority, non-realtime service using excess bandwith and thus not compete with calling like #EDGE and #CSD would.

@stman @kDelta @Sempf @LaF0rge Personally I think that with all it's problems, and #GSM as well as it's successive versions have many, #CellBroadcast isn't one of them!

@stman well, there were some commercial services that used #CellBroadcast but for the most part it's best feature is the effective mass alerting of people in an area without needing them to install yet another app or signup to yet another service...

• The [temporary] shutdown of #CellBroadcast caused hundreds of avoidable deaths in Germany alone.

Given the hamfisted "Australian Approach" I disagree.

• Noone here claims #2G or #3G are safe but don't you think stuff like "Emergency Coverage" and #CellBroadcast are useful?

Will be interesting to see if Australia can pull that off without having to reenable 2G, cuz I've not heard of a #4G implementation of it...

@Lili ja, #CellBroadcast geht an alle Endgeräte.

• Per Spezifikation gehen auch Notrufe ohne SIM, nur wurde dies wegen Missbrauch in Deutschland explizit abgeschaltet!

#Phosh's #MobileSetting app has a new panel to configure #CellBroadcast categories. This requires a recent #ModemManager and mobile-broadband-provider-info database:

3/x

And now we have Cellbroadcastd 0.0.2 as well, which fixes a build failure on arm64 and gets the symbol file in order (thanks @agx !)

https://gitlab.freedesktop.org/devrtz/cellbroadcastd/-/releases/v0.0.2

@devrtz @NGIZero @snwh …and as a service to user interfaces/DEs that don't want to add explicit #CellBroadcast support #cbd can now send notifications. Just enabling the setting is enough.

This is configurable on a severity level so you could use a system modal dialog for high severity events and notifications for low severity ones. This is (likely) how we'll wire it up in #phosh once everything has settled in.

Mostly #phosh/#LinuxMobile (e.g. alarm-clock, #feedbackd, #Cellbroadcast) related but also some #Debian bits.

to everyone supporting this!

@FediNINA_Bielefeld @social.prepedia.org funzt unter Mastodon, ===b :) jedoch bei mir ohne Ton/Viberation :( ----
--- #CellBroadCast auf gut durchgereifte Handys wie das Siemens #S35i, wo man es bereits laut Handbuch 07/ 2000 S. 47 unter Meldungen > CB-Dienste aktivieren kann,
funktioniert der spezielle #DE-Alert leider nicht :(
----

@FFMbyBicycle Leider ist mein Siemens S4 und die Siemens S35i , sowie die bq Aquaris X5+ und X pro anscheinend immer noch nicht dabei. ==p :( Ja, weil man in D~land meint spezielle neuste Normen nutzen zu müssen, als sich am weltumspannenden Standard von #CellBroadcast zu orientieren, so dass auch - ausländische - alte #Handys die #lebensrettenden Nachrichten erhalten. --+ Die Liste ist nicht allzu lang s.
