What is push-to-talk over cellular (PoC)? 

Push-to-talk over cellular (PoC) technology is a real-time communication technology that enables instant voice communication using cellular networks (3G, 4G, 5G), Wi-Fi, and satellite connections. It enables users to communicate across vast distances, without geographical limitations. 

With a single button press, PoC users can instantly communicate one-to-one or one-to-many, send text messages and multimedia, share live locations and trigger emergency SOS alarms.

PoC platforms also include advanced capabilities such as GPS tracking and geofencing, lone worker protection, workforce management, remote device management control and voice recording. 

How does PoC work? 

Unlike traditional radio systems, which rely on radio frequencies and infrastructure, push-to-talk over cellular (PoC) uses cellular networks, Wi-Fi and satellite, enabling users to seamlessly connect across cities, countries and even continents. 

Push-to-talk over cellular (PoC) applications work on both Android and iOS smartphones and are also compatible with other PoC devices, including rugged and field-ready devices. PoC applications are mobile network agnostic so they can work across any mobile operator, Wi-Fi network or broadband connection.

Dispatch console software provides centralised control, enabling visibility, coordination and management of field workers from a central command and control centre. The software is quick and simple to install to a PC, laptop, or tablet, and then to connect to a PoC platform. 

Push-to-talk (PoC) technology has significantly increased in reliability over the last few years due to a number of factors, including the improvement in mobile network infrastructure. Now, the widespread roll-out of 5G has taken PoC to new levels.

Key benefits of push-to-talk over cellular (PoC) 

Global coverage 

PoC eliminates the geographic limitations and costly infrastructure of traditional radio systems. By using cellular and Wi-Fi networks, it enables communication across cities, countries and even continents. 

Lower cost and faster deployment

With PoC, there is no need for radio towers or repeaters which significantly reduces upfront investment and ongoing maintenance costs whilst enabling rapid deployment.

It also means that the solution can be scaled from small teams to thousands of users quickly and easily. 

High reliability

Modern PoC platforms offer real-time communication, high uptime and exceptionally low latency.  PoC technology can seamlessly switch between cellular and broadband technology, ensuring continuous communication. 

This high reliability significantly enhances business communication capabilities and improves operational efficiency and coordination, reducing downtime and enabling quicker decision-making and response times.

Advanced features

As well as voice communications, text messaging and multimedia sharing, PoC applications offer an advanced feature set, including GPS location tracking, voice recording, live video communication, remote device management, workforce management and emergency SOS features.

Secure

Push-to-talk over cellular (PoC) systems frequently incorporate robust end-to-end encryption, user authentication, access control and secure data transmission, ensuring that sensitive information remains safeguarded.

Integration with existing LMR systems

PoC technology can easily and cost-effectively integrate with LMR systems, including DMR, TETRA and P25. This enables legacy radio users to extend the life of their existing radio systems, control costs and migrate to PoC over time.
