How HORIZON Works

HALO Nationwide

Hytera PoC devices access the HORIZON PoC cloud server through the internet using 4G/5G/LTE cellular networks and Wi-Fi networks for wide-area radio communications.

PoC is also referred to as Radio over IP (RoIP). Similar to Voice over IP (VoIP), RoIP devices are handheld two-way radios that access cloud-based PoC services via the internet for nationwide calling. A data plan SIM card (like those used in cell phones) is installed in the PoC device to enable access to the internet using the 4G/5G/LTE cellular infrastructure of Mobile Network Operators.

The result is nationwide calling using existing and reliable networks that require no maintenance or operational expenses.
