Where cellular PTT fits
Push-to-talk over cellular uses carrier data or Wi-Fi to carry group voice through a PTT service. It suits mobile dispatch, transport, facilities teams and multi-site operations that already have working data service. A conventional land-mobile-radio system may be a stronger choice where a single site must keep working without carrier coverage, or where the job requires a dedicated local radio system.
Check each US carrier at the actual work sites
The FCC National Broadband Map lets you compare reported mobile availability by provider. Its mobile maps describe expected outdoor or in-vehicle service; they do not show indoor coverage. A map is a shortlist, not a guarantee that a warehouse, basement or rural route will support PTT voice. Test the device, SIM, carrier plan and Wi-Fi handover that the fleet would actually use. Do not assume a SIM may roam on every network merely because the hardware supports their bands.
How is this different from FCC business-radio licensing?
A cellular PTT subscriber generally buys a service on a carrier network rather than seeking an individual FCC licence for a private radio frequency. A conventional business radio system is a different decision: the FCC's Part 90 Industrial/Business Pool has its own authorisation and coordination rules. A handset that also transmits on conventional radio frequencies may require separate analysis for that function. This distinction matters when comparing bids that look similar on a product sheet.
Compare a full US fleet quote, in USD
Request an itemised quote for devices, data, PTT platform, dispatch seats, support, replacements and any contract minimum. Include coverage testing and accessories. We do not publish a US dollar price here because a carrier agreement, data allowance and device mix change the total materially. Compare the three-year total with a properly specified conventional system, including its FCC licensing and any repeater work.
Run a pilot designed to find failure
| Test | Where | Record |
|---|---|---|
| Voice intelligibility | Worst indoor room and busiest road | Missed or clipped talk bursts |
| Handover | Vehicle route and Wi-Fi boundary | Time to recover and reconnect |
| Group operations | Actual dispatch shift | Wrong group, delayed alert, blocked speaker |
| Outage behaviour | Known low-signal location | What staff do when data disappears |
Keep the results per location and provider. If one route or building cannot pass, change the network design or retain a conventional radio path for that job. For UK readers, see the separate UK coverage guide.
