PoC Radios

PoC, or push to talk over cellular, is a two way radio that combines traditional radio functionality with modern mobile phone technology using a SIM card and Wi-Fi meaning workforces can communicate instantly at the push of a button, wherever they are in the world. These are ideal for businesses that are looking to improve productivity and efficiency.

Due to PoC radios using mobile technology, this means communication can work over SIM cellular, 3G, 4G, and Wi-Fi networks. Because of the range of networks they use, they can sometimes be referred to as push to talk cellular, PTOC, PTT, Wi-Fi radios, or internet radios. The networks allow for multimedia services to be used on the radios, including location sharing and instant messaging. Keep everything in one place with PoC radios.
