Radio, FirstNet and broadband: what is different

Where each one is the right tool, and why 'we have FirstNet' does not answer an interoperability question.

Full guide planned · 10 min read

The short version

Land mobile radio and broadband do different jobs, and the argument about which one is 'the future' obscures that. LMR is built for one-to-many voice that works when everything else has failed. Broadband carries data, video and applications, and depends on infrastructure that can be congested or damaged. Most departments will run both for a long time. The real question is not which to buy but how they hand off to each other.

Start here

If you read one thing on this subject, read this.

Official resourceCISA

Interoperability Continuum

The federal framework for communications interoperability, covering governance, standard operating procedures, technology, training and usage.

Why it matters

The single most useful corrective to the idea that interoperability is a purchase. Four of its five elements are things no vendor can sell you.

The FirstNet network

How the public safety broadband network is built, prioritized and deployed.

Why it matters

FirstNet augments land mobile radio rather than replacing it. Understanding where each belongs stops a lot of wasted argument.

SAFECOM resources

Vendor-neutral guidance on public safety communications, including funding and governance material.

Questions to ask your vendor

Take these into the meeting. A vendor who answers them clearly is one worth continuing with.

  1. What happens to this system when the network is congested or down?
  2. How does it hand off between LMR and broadband, and what does the user have to do?
  3. Does this work at all without connectivity, and in what reduced form?
  4. What coverage evidence do you have for terrain like ours, rather than nationally?

The full guide is still being written

What is above is the Hub’s framing and the best outside reading we could verify — useful on its own, and honest about being a starting point rather than the finished piece. If something here is wrong, or you know a better source, that is worth telling us before the long version is written.
