Abstract (en)
[origin: WO03081555A1] This invention pertains to the use of powerline communications in a civil defence alerting system.The idea encapsulates the use of existing technology in powerline communication via a powerline modem and network data transfer and applies it to the new application of mass public warning.Substantial improvement to both technologies are developed through this invention as the prior art had never included or addressed the need for and ability to communicate over the power lines when no electrical power isflowing from the utility.This invention demonstrates that by using the invented system a user can activate a single alerter device or a multitude of warning alerter devices that are connected to a standard PDN.This invention provides governmental users a more comprehensive and more fail-safe method of warning the public of potentially hazardous situations and safety instructions to minimise the loss of life and injury.
