Traditional walkie talkies (FRS/GMRS) use radio frequencies limited by line-of-sight — typically 1-8 km in open areas, much less in cities with concrete buildings. PoC (Push-to-Talk over Cellular) radios use 4G LTE mobile networks for nationwide coverage. No FCC license, no repeaters, no range limits.

No. PoC radios operate on commercial cellular networks (like your smartphone). Unlike GMRS ($70 FCC license) or amateur/HAM radio (exam required), PoC radios are license-free. You just need a SIM card with a data plan.

Nationwide. As long as both radios have cellular signal, they can communicate across the country. There is no distance limit — PoC radios work anywhere with 4G LTE coverage. This makes them ideal for multi-site businesses, logistics fleets, and teams spread across different cities.

Yes. Our LTE PoC radios (DG6300, M920, M3, DG2000) are fully Zello-compatible. Zello is the industry-standard PTT app that turns your radio into an internet-connected communication device with unlimited channels, message history, and cross-platform support.

IP67 means the radio is completely protected against dust (6) and can be submerged in 1 meter of water for up to 30 minutes (7). Our IP67-rated radios can handle rain, splashes, drops in puddles, and dusty construction environments without damage.
