A Lot Can Go Wrong With an LMR System Upgrade or Replacement — Part Two

Part one of this blog series identified a series of questions that must be contemplated by any agency that is considering a land mobile radio (LMR) system upgrade or replacement project.

A Lot Can Go Wrong With an LMR System Upgrade or Replacement — Part One

Public safety broadband networks, such as the one being implemented by the First Responder Network Authority (FirstNet), are getting a lot of attention these days.

After Radio System Implementation, There Is Still Much to Do

A radio system implementation is an enormous undertaking that requires months, sometime years, of planning followed by years of deployment. The process starts with development of technical specifications and creation of procurement documents, usually in the form of a request for proposals. Vendor responses then must be scored and evaluated. A vendor must be selected, and a contract negotiated, including performance requirements. The system then must be designed, staged, built, and tested to ensure that it is performing as designed. Finally, the system goes live.

And that’s when the real work begins.

Once the new system is operating, it must be managed and maintained, which requires a considerable time investment and an equally considerable amount of expertise and experience. Mission Critical Partners has developed a checklist of 67 tasks that must be performed to effectively manage and maintain a radio system, with most of these tasks falling to the agency to perform.

Four Tips for Agencies Considering Mission Critical Push-to-Talk Apps

A myriad of commercial push to talk application options exist for public safety users, and for good reason. There are many benefits that can be realized by interfacing an existing mission critical land mobile radio system with a commercial push to talk service. You can read all about these benefits on our earlier post, “What is commercial push to talk technology and why does it matter for your public safety land mobile radio strategy?”

Or you can download our free whitepaper on this topic, “The Case for Push to Talk Technology in Public Safety.”

In this post, we will summarize what’s available in commercial mission critical technology, provide some detail around how the solutions work and what their advantages and disadvantages are.

At a very basic level, there are essentially three classes of PTT apps that integrate with LMR systems.

• LMR-based – Apps that are available from traditional LMR vendors such as those that are provided by Motorola Solutions and Harris Corporation
• Carrier-integrated – Apps that are available from commercial wireless carriers
• Third-party – Apps that are available from third party providers
