Private LTE/5G vs public LTE for PTToC and IoT
When to build your own private LTE / 5G network for PTToC and IoT, and when public multi-carrier is the smarter starting point.
Private LTE and 5G (CBRS in the US) let you build a carrier-grade cellular network scoped to your campus, mine, port or plant. It's compelling — and expensive — technology, and it's usually complementary to public multi-carrier, not a replacement.
When private LTE/5G wins
- Underground and enclosed environments where public cellular can't reach.
- Very high device densities (cameras, robotics, autonomous vehicles) that stress public capacity.
- Deterministic latency requirements below what public LTE guarantees.
- Data-sovereignty or security postures that require air-gapped RAN.
When public multi-carrier wins
- Distributed or mobile fleets that leave the campus.
- Deployments where CapEx and RF engineering aren't already budgeted.
- Any team that can start delivering value in weeks instead of quarters.
Hybrid: the common answer
Most industrial deployments end up hybrid: private LTE inside the fence line for cameras, robotics and dense IoT, and public multi-carrier ip³eSIM for anything that leaves the site. ip³Gateways and ip³Radio devices support both, and ip³PTT federates talkgroups across them.
