All information is up-to-date and materials of the report was revised. This report is written in the time when our country is at war with terrorism. Addressing the technical aspects of effective communications between the first responders and the agencies involved in this war at the first line of offense and defense is very important. This is why we see the report as a necessary document to analyze the technologies and the market for the first responders' radios. This report consists of the two major parts and it addresses the following items: -Technology Standardization process Trends Requirements Specifics Roadblocks Architecture -Market Trends Specifics Modeling Forecast Vendors and their portfolio The significance of this report is difficult to overestimate. We are producing a document, which analyzes a complex of issues with the first responders' radios and we are evaluating the current problems with telecommunications technology to support the first responders. We show technological trends and developments of the market for radios used by the first responders, and we stress the importance to equip our police, firefighters and others with the most advanced means of communications. In the today environment, this is not a luxury, but a matter of live or death for many people. Target Audience This report is important for the government agencies involved in the first response to critical situations. It is necessary for technical departments of such agencies to have a document, which in simple language explains radio technology and architectures of networks supporting public safety radios. They also need to have a picture of the market with the major players and their portfolios to select the right equipment. For vendors of the first response technology, this report provides valuable information on competition. It also supports these vendors with the market assessment.
