About GSM PTT Technology
Push-to-talk over Cellular [PoC] is a technology that has been around for years, but acceptance of the technology has been limited due to the limitations of existing mobile phone networks.
With the introduction of 4G networks, PoC has become a much more attractive proposition for many organizations.
PoC combines the features and operational characteristics of two-way radio with the coverage enjoyed by mobile phones.
The radio looks and feels like a conventional two-way radio with on/off/volume controls and channel selector switch. To the user the radio works simply by pressing the PTT. There is no need to set up a call by dialing and waiting for the call to be answered. With latency similar to DMR radio systems, calls to individual, or groups of radio users, is also instantaneous.
One of the many benefits of PoC radio is national coverage, without the need to invest in expensive infrastructure, or indeed, licencing.
Furthermore, the Dispatch software includes a mapping function that allows the location of other mobile devices to be viewed easily, and allowing office-based staff voice and text messaging capabilities, voice recording and location/tracking of mobile staff.
