Push to Talk over Cellular (PoC)

Push to Talk over Cellular (PoC) combines the functionality of radio and smartphone technology in one device.  PoC can be used nationwide and enables users to have one-to-many and one-to-one communication from their smartphone.

PoC has been available for a long time, however, with the availability of 3G, 4G and the release of 5G networks, along with the proliferation of smartphone technology, PoC has become a powerful means of collaboration and safety for mobile teams.

PoC is easy to set up and doesn’t have any of the licensing restrictions that comes with Private Mobile Radio.  It also isn’t limited to an area or site, and can be used nationwide, wherever there is 3G, 4G/LTE and 5G coverage.

In today’s challenging working environment, teams need to work hard to get things done but the most effective teams will work smartly too.  This means providing mobile workforces with the tools to work together, in order complete each job as quickly as possible. Combined with the use of other mobile applications, PoC users can draw on the support of their mobile colleagues without having to move from the spot.  They can email colleagues a photo of their task e.g. a machine they need to fix, have a quick group chat using PoC, before having  a one-to-one mobile call to assist with the task in hand.

Teams also need to work safely too.  And with the recent new rules regarding social distancing likely to remain in place for the foreseeable future, companies will now need to implement strict lone working measures to keep teams apart and safe from one another.  Which means more employees having the capability to raise an alarm and alert colleagues to accidents or incidents.  This is where lone worker applications  that are fully operational on the same handset are a necessity for today’s modern mobile workforce.    

For more information about how PoC can help your teams work together more effectively and safely please see information detailed below.
