The ABC has a a story on the ANU’s grand plans to get every student’s mobile phone number into their emergency messaging system.
A death sentence for all the inconsiderate bastards who can’t be arsed maintaining a phone?
which would have an image or sound that could be used to verify the authenticity of the message
And someone couldn’t just forge the sound/image in a fake MMS?
Its Schmerica first off, and I didn’t have a choice. They don’t have my degree at the ANU.
Delays and the time it takes for a message to be dispatched are reliant on many factors. Local network load, individual cell tower usage and back-end capacity such as the servers which the message goes through.
One also has to question what form of message the ANU will use. If they use just plain SMS, then anyone can send prank warnings. So they may use MMS, which would have an image or sound that could be used to verify the authenticity of the message. IF they were to use MMS, the we are no longer talking a few bytes (i think about 64byts for a full SMS), but a few kilobytes. That may not sound like a lot, but when you multiply it by 15,000… you have a massive influx of data on to the network.
The point I think though is not to get the message out to every single person, but rather to get the message out to a broad group, from whom others can hear the news. All you need are a few dozen people on campus, in Civic and around the CBD and the message will soon spread.
Yea Schmeria, but that is UC, and really does anybody care about UC? compared to ANU it really doesn’t matter.
Well, I have friends who recieve text messages days after they were sent. So, it depends on the network your with and I guess your phone. My phone is prone to dropping off the network which is a pain.
At UC, in some lecture theatres you can’t recieve a single bar of reception, good for not being distracted, but I guess bad in case of emergency.
Is SMS guaranteed delivery? Email, for example, is not.
Maybe jamming up the phone networks is actually part of the plan to reduce public panic!
Spreading the load over the whole network would be better anyway.
Caf: there has been some talk about the ACT emergency services establishing an opt-in SMS alert service as one way to get better alert penetration.
Why not put the question to the telcos? ANU should have done this themselves, but I’m guessing that they haven’t – because the answer most likely would be along the lines of “the mobile phone network is not designed as an emergency warning system”. SMS traffic is treated as low-priority, I wouldn’t be surprised to see delays of several hours if this was actually used.
There’s a reason that the cops and firies still use push to talk radios.
As is Canberra Stadium, where things bog down just with normal traffic having all those people in the one spot.
Do you support or oppose the construction of stage 2 of light rail from Civic to Woden?
