Push-To-Talk Over Cellular (PoC) - What Is It?

Posted by Two Way Direct on 23rd Sep 2022

What is Push-To-Talk Over Cellular?

PoC (PTT over Cellular) is a system, which utilizes LTE cellular infrastructure to provide coverage nationwide. So, basically it allows radio users to connect to others through data networks. Users are able to receive instant connectivity with others who are also connected through Wi-Fi, 3G or 4G.

Along with the ability to communicate instantly nationwide, another benefit of PoC communications is the ease of adding onto a system without the need to expand infrastructure as would be required with a typical two-way radio system.

PoC radios possess the advanced features of DMR (Digital Mobile Radios) such as group calling, GPS, emergency applications and messaging combined with LTE cellular networks in order to allow for nationwide operations.

How it works:

Using a SIM card such as the ones in cell phones, PoC devices utilize carriers such as AT&T, Verizon etc. Connecting through these networks allows for more reliability and does not require extra maintenance or cost on the user’s end.

Gateway routers provide connectivity between the LTE network and the PoC server. Any application utilized on these devices operates on the PoC cloud server, which is through the internet. Also, these PoC services are hosted in the cloud, which means that they operate on privately hosted servers that operate via the PoC platform.

Another major benefit of PoC is that they can automatically switch onto the LTE network when devices are out of range of Wi-Fi.

Forget about connectivity issues and added costs while communicating nationwide when you are working with Push-To-Talk over Cellular.
