Push to Talk Radios (PoC)

Push to talk Radios over cellular (PoC) solutions first appeared on the market over a decade ago following the release of the first set of specifications drawn up by the Open Mobile Alliance (OMA) in June 2005. PoC had some take up in North America using 2G and later 3G services, but made little headway in Europe. All that has changed in the last two to three years thanks to the roll out of commercial 4G LTE networks. 4G delivers the data speeds and low latency to rival PMR systems, which has helped to transform PoC into a seriously attractive proposition for many (although by no means all) organisations, particular those for whom communications are not necessarily business or mission critical.
