Both New York and Washington DC will be rolling out their new PLAN emergency alert system that will inform users when there is something that they may need to worry about. They have been testing the system over the course of the last few weeks on a weekly basis. As of right now, the system has never been used in an actual emergency while they test things out. But, they have announced that the alert system will be going mobile in New York City and Washington DC this year. They will also be going nationwide by 2012.
The system will give you a notification as soon as an emergency happens that will allow for you to prepare for any emergencies that are happening in your area. The push notifications are great because you do not have to open any apps to see the emergency messages as soon as they are sent to you.
A GPS will probably be used to help them determine where you are in order to deliver the messages that make sense for you. The push notifications that they use will be great because it will allow for people to be notified as soon as there is an incident in the city that they are in. The push notifications have been confirmed to be using the actual location of the device such as unlocked Apple iPhone 4 and not just the number that is attached the device to determine who sees the messages.
The notification system will be used only in case of safety threats to the population, presidential announcements and in some situations amber and missing persons alerts. This will be the fastest, easiest way to notify unlocked iPhone 4 users when someone has gone awry and they would like for all users to have an understanding of the situation around them in their area for their own well being.
