The faculty and students are focused on solving some of the world's most pressing challenges: clean and sustainable energy, disease diagnosis and treat- ment, national defense and security, and many others. Georgia Tech's undergraduate, master's and doctoral degree programs range from technol- ogy-focused business and liberal arts to science and engineering, and are consistently recognized among the best in preparing students for success in a world where technology touches every aspect of our daily lives. Challenge Naturally wireless technology is an integral part of campus life at Georgia Tech. Students regularly bring multiple wireless devices to class such as smartphones, tablets, and laptops, and expect to be able to use them to do research on the Internet, access email, and view shared online classroom materials. Georgia Tech's auditoriums typically seat between 200 and 300 students. With such large concentrations of wireless users attempting to access the network at once, they were in- creasingly having issues with inter- ference and connectivity with the ex- isting wireless system in these areas. Ceragon Helps State of Nebraska Build a Reliable, High-Speed, Public Safety Network Case Study Submitted by Ceragon Networks With urban areas to its east, Nebraska is mostly rural. Eighty-nine percent of its cities have fewer than 3,000 people and the state is the ninth least-densely populated state in the U.S. Disparate Public Safety networks across Nebraska's eight regions lack pan-state intercon- nection to address statewide emergencies that will enable dispatchers, first-responders, and emergency managers to communicate with each other and to provide rapid access to vital data between regions. The State of Nebraska has prioritized the need to achieve interoperable communications as its No. 1 priority. In order to achieve this goal, the state is working with the Department of Homeland Security to implement scalable micro- wave technology and provide a baseline infra- structure that can interconnect with other systems and expand with user demand. The Challenge nect 133 Public Safety Answering Points (PSAPs), 911 centers, and other radio link locations utilizing a redundant licensed micro- wave network infrastructure. means for legacy and new applications to function between all regional organizations, including both voice and data. cent link availability and continue to function should a failure occur at an individual location or group of locations. radios must be able to achieve 100 Mbps ca- pacity over links as long as 20 miles. The Solution The Nebraska local government, through its emergency management community, is address- ing its pan-state Public Safety challenges by creating the Nebraska Regional Interoperability Network (NRIN). NRIN is a statewide wireless communication system for Public Safety agencies and public power districts. The wireless system includes more than 200 towers across the state with ring topologies and other backup techniques to guaranty resiliency and very-high reliability in emergency conditions, commissioning and maintenance. Among other capabilities, NRIN will provide the network infrastructure for the "Paraclete" system, which enables local, regional, and state emergency responders to communicate using dif- ferent radio communications systems. Paraclete also contains a sophisticated database that can be customized by local officials to track the avail- ability of resources needed in an emergency. "The problem is everyone has to share an ac- cess point," says Bill Lawrence, RCDD, NTS, WD, Georgia Tech IT project manager.
