What is Push to Talk Over Cellular (POC) ?

Push to Talk Over Cellular is a wireless two-way communication technology, which complements a DMR (Digital Mobile Radio) radio network by maintaining a continuous, half-duplex active connection within or between groups of users. Push-To-Talk is a method of Voice Communication that allows you to simply press a button for instant communication.

The SARTCOM system is utilizing Cellular network to make instant calls that behave like conventional two way radios with instant connection, NO Dialing, NO Waiting Time for the call to be answered to Facilitate group communications across a dispersed workforce.

How do you get the same message to multiple staff members, quickly and efficiently? How do you equip all staff members with appropriate communications devices, seamlessly and cost-effectively?

Push to Talk Over Cellular maintains a continuous active connection between users, callers do not need to dial numbers and receivers do not need to actively answer calls. A push of the button is all it takes for every member of the group to hear the caller. This means seamless integration between your DMR radio network and the Push to Talk app on your smartphone.

Push to Talk Over Cellular is especially useful for organisations that need wide geographical coverage, such as logistics firms with extensive fleets of vehicles, and those who have key stakeholders who do not have access to radio devices but need to communicate with users on the radio network. A desktop POC client can also be set up at a centralised office to act as a dispatcher, while multiple groups of users can be established within the fleet

When you have an existing DMR communications solution, a lot of these problems are solved. But what do you do when some key stakeholder are outside the range of your DMR network
