@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.
