PoC Radio FAQ: Licence, Range, Cost & Which to Buy

The questions procurement managers, security leads and operations teams actually ask before switching to Push-to-Talk over Cellular (PoC)—answered plainly, with Uphone's rugged 4G/5G PoC lineup as the reference.

1. What is a PoC radio and how is it different from a traditional two-way radio?

A PoC (Push-to-Talk over Cellular) radio carries instant voice over 4G/5G mobile networks and Wi-Fi instead of a private radio frequency. A traditional two-way radio is limited by handheld power and repeater coverage; a PoC radio works wherever there is cellular signal—across a site, a city or a country—with no radio licence and no repeater to build.

Uphone's L-series and N-series PoC radios keep the familiar big side PTT button and loud speaker of a walkie-talkie, but route audio as data through the cellular network. Press the button and your voice reaches one colleague or a group of hundreds in under a second.

2. Do PoC radios need a licence?

No. Because PoC radios transmit over commercial mobile networks rather than licensed radio spectrum, they do not require an Ofcom (UK) or equivalent radio licence. Instead of a one-off licence fee you pay a recurring airtime plus PTT-platform subscription per device. This is one of the main reasons businesses switch from conventional business radio to PoC.

3. What is the range of a PoC radio?

Effectively unlimited within mobile coverage. As long as there is 4G/5G or Wi-Fi signal, a PoC radio connects one-to-one or one-to-many across a building, a city or internationally. Range is no longer set by radio power or repeaters but by the carrier network your multi-network SIM attaches to.

4. How much does a PoC radio cost—handset and monthly subscription?

Industry pricing typically runs about US$70–$450 per rugged 4G handheld, plus a service plan of roughly US$15–$30 per radio per month for nationwide LTE airtime, PTT platform, GPS reporting and OTA management. There is no Ofcom licence fee and no repeater or tower lease.

5. What happens to a PoC radio when there is no cellular signal?

A pure PoC device has no coverage where the mobile network does not reach. In practice this is mitigated by Wi-Fi fallback indoors and by multi-network (roaming) SIMs that attach to the strongest available operator.

For safety-critical sites that must communicate during a total network outage—basements, quarries, below-ground or remote areas—a conventional DMR radio or a hybrid device that bridges DMR and PoC (such as Uphone's dual-mode L2402 and L503) remains the responsible choice. Plan the trade-off honestly before deploying.

6. Are PoC radios rugged enough for industrial and security use?

Yes. Uphone's L-series and N-series PoC radios are rated IP68 (dust-tight and water-submersible; the compact L2406 is IP54 for lighter splash exposure) and tested to MIL-STD-810H/G for shock, vibration, humidity and temperature. They use drop-rated housings, front-facing loud speakers and long-shift batteries, and are suited to jobsites, warehouses, field operations and security patrols.

7. Which industries and teams should use PoC radios?

PoC suits teams that move or span multiple sites: logistics and delivery fleets, warehousing, security patrols, construction firms running several sites, utilities and field service, public safety and events crews. Conventional radio still wins for a single site with no monthly-cost appetite, or for safety-critical comms that must survive a network outage.

8. Can PoC radios do GPS tracking, dispatch and lone-worker alerts?

Yes. GPS location, geofencing, emergency/SOS buttons, messaging and dispatch console support are standard on most PoC platforms. Uphone PoC radios support GNSS (GPS + GLONASS + BeiDou), one-touch SOS and can be managed through MDM/dispatch software so a control room sees every radio on a live map and assigns talk groups remotely.

9. Can a PoC radio integrate a body camera?

Uphone offers an integrated ecosystem: the PoC lineup and the body-worn camera lineup (models such as L240, L2408, L310 and N316) share the same rugged, GPS-enabled, dispatch-ready platform, so security teams can pair push-to-talk with video evidence capture. Some PoC models also add a built-in camera for field documentation.

10. Can PoC radios work with my existing conventional or DMR radios?

Often, yes. Many deployments run a hybrid fleet—conventional DMR on-site, PoC for supervisors and drivers—and some platforms bridge the two so everyone shares talk groups. Uphone's L2402 and L503 are dual-mode devices that combine DMR and PoC in one handset. Interoperability depends on the PTT platform, so confirm your setup with Uphone.

11. Is Uphone ATEX-certified for hazardous areas?

The Uphone L503 PoC radio is offered with optional ATEX/IECEx certification for use in hazardous (explosive) environments such as oil & gas, mining and chemical sites. Verify the exact Zone rating and certification documentation for your site with Uphone before specifying, as certification is model- and configuration-specific.

12. When do I need 5G instead of 4G PoC?

Choose 5G when you need higher bandwidth for video streaming, thermal imaging or data-heavy dispatch. Uphone's N630 (MediaTek Dimensity 900, 5G) and N660 (Dimensity 1080, 5G, with thermal imaging and an 8300 mAh battery plus 33 W fast charging) are built for those bandwidth-intensive, field-first scenarios. For most fleet, security and logistics voice needs, 4G PoC is sufficient and more economical.
