FirstNet Public Safety Broadband Network

The First Responder Network Authority has given its partner, AT&T, the approval to build out FirstNet, the nationwide public safety broadband network. This includes deploying public safety’s dedicated spectrum – Band 14 – across statewide radio access networks in states and territories across the country. The buildout will increase coverage and capacity for first responders in every state and territory, including those in rural areas. Currently, FirstNet services, including priority and preemption, are available over AT&T’s existing nationwide multi-band network, allowing first responders to immediately benefit from the FirstNet solution.

Once implemented, the dedicated FirstNet core network will be the foundation for the delivery of advanced public safety features unique to FirstNet, including:

  • End-to-end encryption.The FirstNet core comes with FIPS 140-2 compliant VPN solutions, radio, transport and network core encryption, and advanced physical and logical security protocols to keep all traffic on the network protected.
  • Round the clock security monitoring.The FirstNet core will be monitored at all times by a dedicated Security Operations Center with a dedicated team. Their sole focus will be to monitor the security of the network.
  • Superior reliability and availability.The FirstNet core will help enable the network’s 99.99% end-to-end service availability objective. There will be multiple geographically distributed locations nationwide that house core network elements to enable redundancy and performance.
  • Local control.The FirstNet core will unlock different levels of priority paired with a local control interface. This means incident commanders and eligible first responders can boost priority levels to best support specific situational responses.
  • Mission critical functions.The FirstNet core will deliver a range of next-generation public safety capabilities that are currently being developed based upon open standards specific for public safety. Going forward, these will include services such as Mission-Critical Push-to-Talk, enhanced location-based services and more.

The vast success of LTE/LTE-Advanced becoming the wireless communications standard for delivery of mobile broadband data and high-definition (HD) voice has led to a commitment of governmental authorities to select LTE as the underlying technology for their next-generation public safety networks.

The US regulator, the Federal Communications Commission (FCC), set aside 20 MHz of paired spectrum during the 700 MHz auction in 2008. This spectrum is intended for a nationwide broadband public safety network, deployed, operated and maintained by the First Responder Network Authority (FirstNet).

At the same time, the 3rd Generation Partnership Project (3GPP) has taken on the task of enhancing the current LTE specification and adding important features like device-to-device (D2D) communications, group communications or mission-critical voice for push-to-talk, in order to get the technology ready for critical communications. These features and functionalities are targeted for the upcoming Releases 12 and 13. However Release 11 already added a feature that allows an LTE-capable device operating in Band 14 to transmit with a much higher output power than any commercial device required to overcome coverage gaps in rural areas. This, together with all other features and functions, requires extensive testing on all layers: RF, PHY/MAC, protocol, conformance, infrastructure and the network itself.

Public Safety Applications

Event & Infrastructure Monitoring

Providing security for confident conferences, large events and critical infrastructure is an increasing demand. Criminals make more and more use of electronic devices for executing illegal acts. Rohde & Schwarz provides solutions for detecting and locating bugs (micro transmitters), potential interferers, illegal intruders or other threats.

Monitoring Large Events

Large events pose potential risks for visitors and the organizers. The monitor the radio spectrum that is used during the event, by rescue services and others as the first priority, but also the spectrum that is required for broadcasting the event must kept clean. Interference in communications links not only costs  money, but also risks lives. Monitoring the spectrum can also detect suspicious communications, allowing authorities to track and eliminate possible threats.

To enhance large event safety, Rohde & Schwarz frequently supplies radiomonitoring systems. Before and during the games the systems are deployed for verifying the spectrum’s occupancy and detecting, analyzing and locating suspicious emissions. With no harmful interference or suspect signals, organizers remain composed and spectators enjoy the games in the stadiums and via TV.

Search & Rescue

When it comes to saving life of mariners in distress or lost in disaster areas, Rohde & Schwarz provides solutions for detecting and locating people in emergencies. Our systems support efficient rescue operations and mitigate risks for the people in distress and for the rescue staff. They speed up the rescue by shortening the search period, thus increasing the survivability of distressed people and cutting the cost of rescue operations.

Combat Trafficking

Protecting a nation from contraband is a challenge for customs and border police as the smuggling of drugs, weapons, and human trafficking is an increasing issue worldwide. In order to counter these illegal acts, authorities of several European countries with external borders of the Schengen territory operate with mobile border surveillance systems from Rohde & Schwarz. These systems are mainly integrated in suitable off-road vehicles and can there be operated several hours independently, allowing them to intercept valuable data in order to prevent or prosecute crime along the borderlines.

Panel Discussion: LTE for public safety – are we ready?

Today, usually two separate wireless communications systems are in place to serve the needs of commercial applications on the one hand and critical communications, often referred to as public safety, on the other hand. This is due to the very different requirements for both systems. The vast success of LTE/LTE-Advanced becoming the wireless communications standard for delivery of mobile broadband data and high-definition (HD) voice has led to a commitment of governmental authorities to select LTE as the underlying technology for their next-generation public safety networks. At this panel we will explore if the technology is ready, if not what is missing. How the eco-system for LTE for public safety is shaping up. These and other question will be answered during the discussion.

LTE network optimization for public safety

Michael Schwab — P3 Communications, Inc Public Safety and Critical Communications Entities have been focusing on speech services and low data rate applications for decades. Nowadays information flow is frequently limited by interoperability problems like different standards or independent systems. Long-Term Evolution (LTE) has a chance to revolutionize the public safety sector and its processes…

LTE for public safety

Device solutions for commercial wireless applications and public safety applications have both common aspects and differences. Elektrobit has been developing specialized solutions for specialized, vertical wireless markets for many years, bridging the gap between mainstream commercial wireless and public safety. Device solutions for LTE Band 14 require specific features and functionality in order to serve first responders. Elektrobit addresses these requirements and needs in its product development for public safety.

Understanding E911 Device Compliance in a VoLTE/IMS Environment

Delivering E911 services is an FCC requirement and has been a part of legacy services for some time. In order to support emergency services for VoLTE subscribers, many new items need to be considered from a device and network perspective. For example, the transition from a traditional circuit switched (CS) network to an all IP based network utilizing IMS for voice calls; and the addition of new positioning methods such as eCID, OTDOA, and A-GNSS with a new information exchange protocol (LTE Positioning Protocol); all add new dimensions to this mandatory feature that vendors must now ensure via functional and performance compliance of their devices.
