The quiet migration off two-way radio
Across industries, trunked radio estates are reaching end-of-life — and operations are choosing networks over towers. A field guide to the transition.
It rarely makes headlines, but it's happening everywhere: a repeater lease expires, a handset fleet ages out, a coverage complaint lands on the wrong desk at the right time — and an organization that has run on two-way radio for thirty years quietly decides not to renew.
Why now
Three curves crossed. Mobile networks became more reliable than most private radio estates. Smartphones became rugged, cheap and universally familiar. And the feature gap inverted: location, messaging, translation, recording and SOS are native to network PTT and expensive afterthoughts on radio.
What remains for radio is genuine spectrum independence — and satellite fallback is eroding even that argument for all but the most specialized users.
Migrating without drama
The playbook that works: run both systems through one season, mirror your radio fleet map as channels, keep the accessories crews already trust — earpieces, speaker mics, PTT buttons — and let the dead zones make your argument. Most organizations find the second system becomes the first within weeks.
