Among other purposes, the American Recovery and Reinvestment Act provides funds to preserve and create jobs and promote economic recovery and to provide investments needed to increase economic efficiency by spurring technological advances in science and health. In addition to supporting the goals of the Recovery Act, this project also supports the purposes of the Byrne Justice Assistance Grant Program by helping to increase the economic efficiency and effectiveness of law enforcement activities. This project will address law enforcement technology requirements and priorities in the areas of ' officer safety, public safety, and communications (including interoperable communications). In consideration of the goals, objectives, and intended impact of the Recovery Act, priority consideration has been given to proposals that demonstrate the potential for increasing law enforcement efficiency and effectiveness and/or support job creation or preservation on an expedited time frame. This project will deliver a prototype commercial Digital Signal Processor with ported Public Safety Cognitive Radio code. The benefit to public safety of the addition of a complete Public Safety Cognitive Radio solution into any Land Mobile Radio product is increased flexibility in Public Safety communications. This project will create jobs and new technology.
