Push-to-talk over cellular devices combines the simple operation of traditional radios with the coverage of modern mobile and Wi-Fi networks. A PoC radio no longer works only locally but across multiple locations, making it ideal for businesses with several branches, mobile teams or widely distributed sites. PoC walkie-talkies, 4G walkie-talkies and 4G two-way radios are the right solution wherever the range of conventional radio systems is no longer sufficient.






PoC systems use existing data connections instead of traditional radio frequencies. This means that as long as mobile coverage or Wi-Fi is available, teams can communicate with virtually no conventional range limitation. This is especially relevant for businesses with sites spread across regions or mobile staff who are constantly on the move.
The main advantage lies in the combination of simple push-to-talk operation and features that conventional business radio can only provide with additional infrastructure, such as real-time location tracking, central user management or dispatcher software. This makes PTT over cellular a modern communication platform for connected teams.
| LTE / 4G / 5G module with SIM slot | Communication via mobile networks instead of local radio range. |
| Wi-Fi support | Can be used inside buildings or at sites with their own network. |
| Android operating system (model dependent) | Enables flexible management as well as additional apps and applications. |
| Push-to-talk server integration | Central communication structure for group calls, individual calls and management functions. |
| Real-time GPS tracking | Helps coordinate mobile teams and vehicle fleets. |
| Dispatcher software compatible | Control rooms can manage communication centrally and organise teams. |
| Large push-to-talk button | Simple operation, just like a traditional radio. |
| Long battery life (3000–5000 mAh+) | Suitable for mobile teams and full-day use. |
| OTA programming and remote management | Devices can be configured and updated centrally. |
| Noise suppression | Improves voice quality in vehicles, warehouses or outdoor areas. |

Businesses with teams spread across multiple sites find PoC walkie talkies particularly suitable. In logistics and transport, they connect drivers, warehouses and dispatchers in real time. Multi-site businesses can coordinate staff across several locations without having to build a separate radio network for each branch.
Security services, event organisers, field teams and technical service providers also benefit from the fact that PoC radios are not limited by conventional radio range. A 4G walkie-talkie, or 4G two-way radio is especially valuable wherever teams work on the move and still need to be centrally coordinated. In buildings or fixed locations, Wi-Fi can also be used.
Onedirect helps businesses choose the right cellular radios and PoC radio solutions. With tailored advice, fast delivery, permanent stock availability and competitive prices, even larger rollouts can be implemented reliably. This is supported by radio programming, official accessories and a dedicated after-sales service.
What are PoC radios?
PoC radios (push to talk over cellular) use mobile networks or Wi-Fi instead of traditional radio frequencies and allow communication over long distances.
What range do PoC radios offer?
Because they work through mobile networks, PoC radios can communicate nationwide or internationally, as long as an internet connection is available.
Do PoC radios need a SIM card?
Many devices require a SIM card or mobile data connection to operate over LTE or 4G.
What advantages do PoC radios have over traditional radios?
They offer very wide coverage, multi-site communication and central management through software platforms.
Which businesses benefit most from PoC radios?
Typical use cases include logistics, transport, security services, facility management and branch networks with multiple locations.
