The Push Module provides your app with the ability to send push messages to Android and iOS devices. Beside the functionality to send plain messages to your apps users, all other enabled modules are enriched with push features; that is, other modules may use push messages afterwards for a variety of use cases.
The Internet runs on standards. Without standards, we wouldn't have the Domain Name System (DNS) which resolves hostnames to Internet Protocol (IP) addresses, or the HyperText Transfer Protocol (HTTP) which served up this very web page. Even web service APIs, which can vary wildly depending on the back-end service, depend on standards like XML and JSON to make third-party development possible. And now, the W3C is jumping into the fray with a Working Draft for a general webapp Push API.
In the case of emergencies such as serious accidents, bomb scares, severe weather conditions, equipment failure or fires and floods, it would be good to know that there's an accurate notification system to keep you informed and ready to react if necessary. AMTELCO’s RED ALERT API is an emergency notification system that is designed to save time, reduce errors and speed up overall response times.
