The First Responder Network, FirstNet, an independent arm of the Department of Commerce, has awarded a contract to AT&T to build a nationwide wireless broadband network to better equip first responders. "FirstNet will provide 20MHz of high-value, telecommunications spectrum and success-based payments of $6.5 billion over the next five years to support the network buildout," AT&T said in its announcement. Reuters reports: The effort to set up a public safety network was triggered by communications failures during the Sept. 11, 2001 attacks, when first responders were unable to effectively communicate as they used different technologies and networks. The FirstNet network will help emergency medical personnel, firefighters and police officers communicate vital information on one single network in real time, as opposed to using thousands of separate, incompatible systems. The rollout of the network, which will cover will cover all states, five U.S. territories and the District of Columbia, will begin later this year, AT&T said on Thursday. AT&T will spend about $40 billion over the period of the 25-year agreement to build, operate and maintain the network.
