When many people think of "walkie-talkie", the traditional hand-held walkie-talkie (two-way radio) may come to mind:

Radio communications are essential for police, ambulances, firefighting, mountain rescue, petrochemical industries, construction and many hazardous work environments to ensure reliable and safe communications during critical times.


However, it's not just emergency services and dangerous work environments that require reliable communication channels.


Transport services such as buses, trains, trams, local authorities, council fleets, schools, universities, taxi companies, event organizers require seamless communication between employees.


PoC sometimes called "Press to Transmit" is a service that provides all the features and benefits of a two-way radio, available on dedicated or Android devices.


How does PoC work?


PoC uses cellular or Wi-Fi networks and does not require any additional infrastructure to cover large areas. This means it provides a cost-effective way to extend the coverage of a radio system that can include non-radio users.


PoC allows users to make one-to-one, one-to-specified group or one-to-many calls by pressing a button, just like a walkie-talkie.


What are the advantages of Push to talk over cellular radios?


No matter where you are in the world, as long as you have a Wi-Fi or cellular network connection, you can quickly and effectively communicate with your members, track and monitor users with GPS location, and instantly send voice commands to individuals or groups without complex or Expensive infrastructure, effectively reducing costs.


PoC works seamlessly on the network, allowing users to communicate across any platform, including cellular networks (2G, 3G, 4G), Wi-Fi platforms, broadband and two-way radio networks, providing the greatest possible coverage.


One-to-one or multiple groups can hold up to hundreds of users, and each user can be configured with a unique profile, defining talk groups and private calling features.


Push-to-talk provides reliable, highly secure business-critical communications, whether over cellular, LTE, or Wi-Fi connections.


In an emergency, PoC has a panic alert button on supported devices.
