PoC, or Push-to-talk over cellular, allows radio users to connect to others through data networks.  Not only that, but it means that users can get an instant response, providing others are connected through Wi-Fi, 3G or 4G.  Naturally, emerging 5G standards will appear very shortly. This means that, ultimately, you can push-to-talk with international users, not just those in close range.  This is a massive boost to anyone managing fleets and teams cross-continent!

How Push to Talk over Cellular Works?

PoC devices connect to the cellular infrastructure of Mobile Network North America Operators like AT&T, T-Mobile, and Verizon, using a SIM card like those installed in cell phones. The result is a highly reliable network that requires no maintenance or operational expenses. An app on the PoC radio provides simple and convenient access to PoC services.

PoC network services are hosted in the cloud. The cloud services are located on privately hosted servers owned and operated by the PoC platform. Gateway routers provide connectivity between the LTE network and the PoC server. Dispatch Applications (used for group calling and GPS location tracking) and the Management Application (used to configure customer accounts) are connected to the PoC cloud server through the internet.
