What is Push-to-Talk over Cellular?

Push-to-Talk over Cellular (PoC) is the method of using mobile devices similar to two-way radios or walkie talkies. It offers coverage far beyond the reach of existing land mobile radio (LMR) networks. Furthermore, PoC applications support many of the same features as digital radios (group calls, GPS location, messaging, emergency notifications, etc.).

However, there are several important reasons agencies may want to maintain radio communications even after implementing a PoC solution. These include avoiding recurring fees, providing intrinsically safe devices, and relying on a communications network more capable of surviving infrastructure damage. Therefore, integrating both systems provides enhanced coverage, reliability, and cost-effectiveness.
