How about the delay? The message is not delivered instantly. Plus, such a system would be required to be already scaled up, and stay in that state always, to support sending messages to millions of "subscribers", which would only add additional delay.
- VMG 12y agoIf you use broadcast messages, the number of subscribers shouldn't matter. There already exists a system like this in the US: http://en.wikipedia.org/wiki/Commercial_Mobile_Alert_System http://en.wikipedia.org/wiki/Commercial_Mobile_Alert_System > CMAS will allow federal agencies to accept and aggregate alerts from the President of the United States, the National Weather Service (NWS) and emergency operations centers, and send the alerts to participating wireless providers who will distribute the alerts to their customers with compatible devices via Cell Broadcast, a technology similar to SMS text messages that simultaneously delivers messages to all phones using a cell tower instead of individual recipients.[3][4]
- rdl 12y agoWill CMAS/cell broadcast bypass iOS Amber Alert and Emergency Alert "Government Alert" settings?
- Sanddancer 12y agoNo. This would almost assuredly be sent as a level 2 extreme alert. The only alert that can bypass the settings is an alert directly from the president.
- diminoten 12y agoWell don't freaking turn off earthquake alerts!
- jessaustin 12y agoIf earthquake alerts are their own category, I probably won't. However, if they're lumped in with much more common events (thunderstorm! non-custodial parent spending time with child!) that I don't care to hear, then I will.
- tedunangst 12y agoFromy experience sitting in a movie theater when a NWS storm alert went off, it took well over a minute for all messages to be delivered.
- sentenza 12y agoWouldn't it be possible to use an IPv6 broadcast, thus making messaging of "everybody" trivial? All that would then be required is that cell phones, pads and computers give some sort of non-mistakeable warning sound upon receiving these packets.
