195 - How 9/11 and Katrina Changed Scanning

Scanner School - Everything you wanted to know about the Scanner Radio Hobby

What changed in the radio landscape in 20 years post 9/11 and Hurricane Katrina here in the US?

Have you ever wondered why we have so many new P25 systems showing up in the 700 MHz band?

These are the questions we are asking in today's podcast.

What You Need To Know

• 9/11 really brought to light some of the changes that had to happen with interoperability.
• Hurricane Katrina, which happened just four years later in 2005, also revealed that changes needed to happen.
• Responding agencies on 9/11 had communication problems on their own two way systems.
• They also lacked a structured plan for communicating to other agencies in real time to alert them of urgent risks to life and health.
• In order to open frequencies for public safety, Congress enacted Spectrum Act 2012
• This directed the Commission to allocate the D block from 758 to 763 MHz and 788 to 793 MHz to public safety for use in a nationwide broadband network.
• FirstNet is charged with responsibilities for deploying and operating a nationwide public safety broadband network.
• In February of 2006 U.S. house of representatives voted 216 to 214 and approved a budget package that required analog television broadcasters to clear the 700-megahertz airwaves.
• Channels 70 to 83 are now part of the mobile radio system’s public safety and trunk system.
• The National Interoperability Field Guide is a technical reference for multi-communication planning and for radio technicians responsible for radios that will be used in disaster response.
• This is why we see so many new P25 systems showing up in the 700Mhz band
