Push-To-Talk over Cellular (PoC) uses cellular and Wi-Fi infrastructure to create a wide-area radio network that provides national coverage for voice and video communications. Today, PoC provides the best of both narrowband digital radios and broadband 4G/LTE networks and can enable wide-area fleet dispatching and instant group voice calling at a low cost.
PoC radios support the advanced features of Digital Mobile Radios (DMR), including messaging, instant group calling, GPS location tracking, and emergency notifications. Combining this functionality with Wi-Fi and 4G/LTE cellular networks provides the national coverage area and bandwidth required for modern data and video applications. PoC radios are also known as Internet of Things (IoT) devices that access the internet for data communications and can also access the internet via Wi-Fi networks like any other mobile device.
