The technology behind Push-to-Talk-over-Cellular is very simple. It is a wireless two-way communication technology that maintains a continuous half-duplex active connection within or between groups of users.
Once PoC technology is integrated across the network, every staff member connected to the system can speak to a member or members of their pre-defined group simply by pressing the Push-to-Talk (PTT) key on their device.
This includes users of cellular devices such as smartphone users who through the use of the mobile app, can use their phones like portable radios to access the DMR network and participate in individual or group calls. PoC solutions can be deployed quickly on existing 2G, 3G, 4G or 4G LTE networks or WiFi networks.
PoC maintains a continuous active connection between users which means that callers do not need to dial numbers and receivers do not need to actively answer calls. Group communications are available at the push of a button saving massive amounts of time for cellular device users. This is a massive operational advantage for centralised staff members and dispatchers trying to manage dispersed workforces; and in the case of the emergency services, it can even save lives.
PoC is a fast and very cost-effective solution to deploy. All you need is an existing radio network in place and additional users, who would otherwise have required a portable or mobile radio device, can connect to colleagues through smartphones using the mobile app. The result is a greatly expanded communications network beyond the coverage of the radio network and increases productivity, safety and other key aspects of an organisation’s operations.
