From Digi: "Cellular Routers to be Critical for Public Safety Communications"
The National Public Safety Broadband Network is the nation’s first cellular broadband network dedicated to public safety. It will be providing more reliable communication for first responders by enabling better device interoperability across public transportation agencies throughout the United States. This new technology will allow agencies to utilize purpose-built transit cellular routers as a means to improve communications. Continue reading to see why fail-safe interoperable network is critical.
PUBLIC SAFETY CHALLENGE
The public safety challenge is to protect citizens and critical infrastructure so that incidents can be mitigated faster with a more coordinated response. And the role of public transportation is only increasing as cities grow larger and denser, as an urban incident will require coordinated dispatch, and perhaps even evacuation. Traffic systems will also be a key element to incident resolution in order to expedite the arrival of response teams and direct traffic flow around the incident, which may necessitate remote access to onboard or roadside cameras and message boards.
However, commercial networks can crash when overloaded and legacy mobile radio networks are not always compatible, which is why a fail-safe interoperable network is required for emergency group communication, multi-media transmission of video, images and data; plus, reliable location tracking, economies of scale and the ability to interconnect with legacy systems also come into play.
CELLULAR-BASED COMMUNICATION SOLUTIONS
The Public Safety Broadband Network is leveraging both existing LTE and advancing 5G international standards for mission critical services over commercial cellular networks. The services are built on new protocols and mechanisms that guarantee priority and preemption for voice, video and data, and will include push-to-talk, group calls and direct mobile-to-mobile. First responder vehicles, traffic control and transit system will now be able to utilize cellular mobile access routers as network gateways that securely bridge local subnets to agency systems. Agencies will need to know how to evaluate routers for ruggedness and security, along with forward compatibility as new public safety applications emerge.
