The Case for Push-to-Talk in Public Safety

In Summary:

  • First responders have long depended on traditional land mobile radio (LMR) systems that feature public safety-grade radios and infrastructure.
  • While commercial networks are typically not ideal for public safety use, as they can become overloaded during an emergency, commercial push-to-talk (PTT) technology could benefit public safety.

In this whitepaper we explore the pros and cons of commercial PTT technology for public safety, including the improvements to commercial PTT capabilities and the cost-efficiencies the technology offers for agencies. 

Regional Computer-Aided Dispatch Models

In Summary:

  • For years, public safety communications systems have operated as standalone systems that are used to serve the citizens of a single geographic area.
  • As communities have grown, the need for improved communication between dispatchers and first responders, and across jurisdictional lines, has increased. 
  • Agencies across the country have begun to consider regional models for their computer-aided dispatch (CAD) and other public safety systems in order to improve efficiency, share resources with other agencies and reduce costs.

In this whitepaper, we explore two models of regional CAD systems and explore the pros and cons of each one. 

How Relocation of T-Band will Affect Public Safety

In Summary:

  • Public safety licensees in some of the nation's top metropolitan areas that currently operate in the T-Band will need to transition their land mobile radio (LMR) systems before 2023.
  • The FCC will reallocate this spectrum via auction as part of the enactment of the Middle Class Tax Relief and Job Creation Act of 2012.
  • Agencies with LMR systems currently on the T-Band face considerable challenges in transition those systems in advance of the 2023 deadline.

This whitepaper discussed the challenges that agencies face during the transition from the T-Band, provides a transitional timeline and offers tips and information for making the transition.

A Blueprint to Help Public Safety Organizations Understand Their Environments

 In Summary:

  • For public safety officials, the task of monitoring and assessing the myriad technological and operational factors that determine the center's success or failure is a big, complicated and time-consuming job.

  • Leaders need help understanding where their centers stand regarding factors such as cybersecurity, IT and networks, next generation 911 (NG911), staffing, and more.

  • MCP's Model for Advancing Public SafetySM, also known as MAPSSM, is a proprietary assessment program that helps assess a program against standards, best practices, and the collective knowledge of MCP's 115+ specialized public safety professionals.


How to Navigate the Complexities of Mission-Critical Vendor Management

In Summary:

  • Today's average public safety agency has more than 30 vendor support agreements to manage.

  • Vendor support agreements have become more difficult to understand given their size and complexity.

  • Public safety organizations are looking for strategies to help navigate the complexities associated with today's increasingly complicated vendor environment.


It used to be much easier for public safety agencies to manage their vendors compared to a decade ago. At that time they were simple and easy to understand and they generally only involved the radio, computer-aided dispatch (CAD) and 911 call-handling system providers.

The Evolution of the Emergency Communications Ecosystem

In Summary:

  • Emergency communications centers are not much different from what they were when they first appeared on the scene a half century ago.

  • PSAPs need to jettison the legacy analog call-handling equipment that has existed for the last 50 years, and replace it with new equipment capable of processing calls and data that originates from digital devices.

  • The evolution of the emergency communications ecosystem will result in PSAPs and telecommunicators that will look and behave very differently than they do today. 


The public safety sector and emergency communications has reached an inflection point. Technology has evolved dramatically, and the needs and expectations of the public served by PSAPs have evolved as well. Data has overtaken voice in terms of importance. As a result, PSAPs need systems that are capable of leveraging the enormous amount of data is that already available, yet inaccessible today. Legacy call-handling equipment equipment that has existed for the last 50 years needs to be replaced with new equipment capable of processing calls and data originating from digital, Internet-Protocol (IP)-based devices.

Workforce Optimization: A Smarter Solution to Resolving 911's Staffing Struggle

In Summary:

  • Staffing struggles have plagued public safety communications for years, and the situation is worsening because of favorable economic conditions that bring an abundance of less-stressful, better paying jobs.

  • Workforce optimization is the concept of taking a more holistic approach to staffing that places equal emphasis on recruitment, hiring, training, and retention.

  • The profile of the ideal telecommunicator is evolving. The next generation telecommunicator will process different skills than they do today.


Several years ago, the National 911 Program released the Recommended Minimum Training Guidelines for the 911 Telecommunicator. The document was intended to ensure that a more consistent standard of care was provided by 911 call-takers and dispatchers to callers requesting emergency services, regardless of their location at the time of the call. A corollary benefit of the guidelines is that they might help reduce the amount of personnel churn that emergency communications centers (ECCs) experience.

Whitepaper: A Smarter Approach to Resolving the 911 Hiring Struggle

In Summary: 

  • Staffing and hiring struggles have plagued public safety agencies for years and the situation is worsening

  • High personnel churn and attrition rates contribute to the shortage

  • Workforce optimization is the right approach for 911 officials looking to resolving 911 staffing struggles instead of simply focusing on recruitment


Staffing 911 centers has become a huge concern in the public safety communications community. In this report, we explore the concept of workforce optimization, of which training is one of four key pillars, with recruitment, hiring and retention being the others. 

Public Safety Should Look Hard at Mission-Critical Push-to-Talk

In Summary:

  • Push-to-talk over celluar (PTTOC) and mission-critical push-to-talk MCPTT services are provisioned over broadband wireless services and replicate the walkie-talkie functionality of traditional land mobile radio (LMR) portable radios.

  • Through gateways, these services can be interfaced with LMR networks to allow audio to be transmitted from LMR channels to the broadband application, and vice versa.

  • They offer a good alternative for personnel who have no need for a digital radio on a daily basis but need to be provided situational awareness and coordinated incident command.


This whitepaper examines push-to-talk over celluar and mission-critical push-to-talk technology, explaining why they may be a better choice than LMR in some cases, and how they provide significantly more flexibility regarding application, device and network choices. The biggest benefit of MCPTT service is that it replicates the PTT functionality of traditional LMR systems on devices that are smaller, lighter and much less expensive than portable radios traditionally carried by first responders. Also examined are important factors to consider when deciding whether to implement the technology.

Next Generation 911: A New World for PSAP Network Maintenance

 In Summary:

  • Next Generation 911 will improve emergency response dramatically, but will bring challenges that require new approaches and skill sets.

  • Network and systems management will become considerably more complicated after an NG911 system has been implemented.

  • Many PSAPs lack the IT expertise to adequately monitor and protect and NG911 system.


What's the Future of Land Mobile Radio in a FirstNet World?

In Summary:

  • Many public safety agencies have pondered whether the Nationwide Public Safety Broadband Network (NPSBN), being implemented by the First Responder Network Authority (FirstNet) will someday replace the land mobile radio systems that have traditionally provided mission-critical voice services.

  • Agencies should continue to invest in their LMR systems, even to the point of replacing them if necessary.

  • Government agencies should continue to track the progress of FirstNet, for the day will eventually come when the NPSBN has developed to the point that it is a viable alternative for LMR.


Many public safety communications officials are wondering if they should replace their land mobile radio (LMR) system now that FirstNet has become a reality. This whitepaper makes the case for why agencies shouldn’t abandon their plans to replace their LMR system.

Now that the public safety sector is contemplating the implementation of an IP-based network known as the Nationwide Public Safety Broadband Network (NPSBN). Although this network was intended from the beginning to ramp up the public safety’s data capabilities in the field, a question was raised whether the NPSBN someday will replace the land mobile radio (LMR) systems that traditionally have provided mission-critical voice service.

The NPSBN eventually could one day satisfy all of public safety’s voice and data needs—the big question is when. Many public safety agencies have legacy LMR systems that are approaching end of life today, raising the question if they should burn up already limited financial resources on an LMR system that could obsolete in a few years. MCP recommends that public safety agencies not abandon the replacement of the LMR system for several reasons:

  • Talkaround still will be an issue.
  • System hardening still will be an issue.
  • Coverage and capacity concerns will note go away, and public safety agencies need to have complete visibility into their LMR systems regarding capacity requirements and how they are achieved.
  • User fees are expected to be much higher than today’s LMR systems.

The Technical Evolution of the PSAP in a NG911 and Public Safety Broadband Environment

In Summary:

  • Data inputs that stream into a public safety answering point (PSAP) are increasing significantly, driven by the fact that public safety broadband and next generation 911 systems are Internet Protocol (IP)-based.

  • This will raise situational awareness in the PSAP to levels unimaginable only a short time ago.

  • Public safety broadband and NG911 must be converged for data to flow seamlessly between these two networks in order to be fully harnessed.


When public safety broadband networks, such as the Nationwide Public Safety Broadband Network being implemented under the auspices of the First Responder Network Authority, and Next Generation 911 (NG911) systems are implemented, responding to emergency events will be dramatically different than it is today for the public safety community. Today, the amount of information that telecommunicators and first responders have is severely limited. In the future, the data inputs that data inputs that stream into a public safety answering point (PSAP) are increasing significantly, driven by the fact that public safety broadband and next generation 911 systems are Internet Protocol (IP)-based.
