Public-Safety Agencies Use Converged Networks to Do More with LessThe renewed focus on homeland security is forcing many departments to find creative ways to meet the security needs of their communities. Article Summary Background [ Return to Top ] Security Needs Encourage the Adoption of Standards-Based Networking In the past, public-safety agencies were often at the forefront of communications technologies. But frequently there were limited ready-to-use commercial networking solutions available for their needs, so agencies were often forced to build—or contract out—their own communications networks from start to finish. While these networks have provided some distinct advantages, proprietary, custom-built networks have many intrinsic shortcomings:
But new business realities and the advent of new technologies—particularly converged IP networking—have finally compelled commercial communications companies to develop standards-based networking solutions. These standards-based, converged network IP solutions offer the following advantages:
[ Return to Top ] Collaboration Is Crucial One of the shortcomings of the custom-built, ground-up network of old is its lack of interoperability. For example, in a single jurisdiction, police, fire, and emergency medical personnel may have had incompatible radio hand-held devices and networks. In an emergency situation, each group of first responders may have had some critical piece of information, but no one group had enough information to see the entire scenario. But IP networks facilitate real-time parallel workflow among agencies, enabling true collaboration and dynamic resource allocation for effective emergency response. No longer is each agency functioning in a vacuum; with an IP network, information gathered by each agency is readily available to every other agency involved in an emergency, and each agency can respond accordingly. Another distinct advantage of IP-based networks is their approach to security. Information security is especially important in public-safety applications, and an IP network ensures that all authorized users—and only authorized users—have access to the information they need. [ Return to Top ] High-Performance Networks Increase Effectiveness When police are in pursuit of a suspect, they no longer have to rely on subjective descriptions of a person or a vehicle; with new IP networks, dispatch personnel can broadcast still pictures or video of the subject. Dispatchers at command and control centers can use GPS to track the movements of first responders in real time. And emergency personnel in the field have instant access to a wealth of information, including road maps, natural gas line charts, and homeowner contact information. Rather than just being able to query DMV databases for license plate and identification information, for example, police officers can search most-wanted lists, warrant lists, and other relevant databases to make the right policing decisions while they're patrolling. These types of solutions would be expensive and difficult to implement on low-speed, proprietary networks. [ Return to Top ] Creative Solutions to New Challenges Roughly 90% of all public-safety agencies have fewer than 100 officers, making them remarkably similar to small businesses in terms of size, and these smaller jurisdictions are banding together to increase their purchasing power. As a result, they can get better deals from vendors and spread implementation costs—and, perhaps more importantly, ongoing IT support costs—among several agencies. Smaller suburban agencies are also looking to their larger neighbors for help. Big cities can actually benefit from connecting their smaller neighbors to their networks; the big city agency can expand the reach of its network, and smaller municipalities can use the city's existing network infrastructure to dramatically reduce implementation costs. These cross-jurisdictional agreements work to the advantage of all concerned, and have significantly enhanced the effectiveness of these public-safety agencies. Another advantage of an IP network is that it does not need to be implemented all at once. In fact, many agencies are choosing to move to IP in three distinct steps: The vehicle network. The obvious starting point is making sure first responders have the tools they need on the ground to deliver their services. Extending the network to the vehicle gives the people on the ground access to critical information that can inform their decisions in real time. It also allows for the secure exchange of information anytime, anywhere, and with any device. This means emergency departments can continue using the equipment they already have, and by tying their communications together via IP, they can begin to take advantage of all that an IP network can offer. The access network. Connecting buildings and agencies together is the next step. By installing wireless network access points, or "hot spots," throughout a jurisdiction and using existing private network hot spots, agencies can dramatically increase the reach and effectiveness of their networks. Public-private partnerships are growing as the private sector steps in to share its bandwidth with public-safety agencies, leading to increased emergency service for not only the owner of the network, but also the community at large. The network back end. Finally, with a scaleable, standards-based network, agencies can continually upgrade their back-end infrastructure. Concerns about obsolescence are a thing of the past. And new services on the network can now be made available—securely—to anyone, anywhere, at any time. Nearly every government agency must accomplish more with fewer resources, but nowhere is the success of this task more important than in the emergency-response community. Since effective emergency response depends on getting the right information to the right people all the time, public-safety agencies can get a much-needed return on investment by prioritizing their adoption of IP-based technologies. They can address their most critical needs first and phase in a robust IP network over time. [ Return to Top ] What Cisco Offers
