Conventional two way radio, or private mobile radio ( PMR ), is limited in range by various factors. PTT is limited only by the availability of GPRS phone coverage. The real advantages of PTT are realised when a “group” conversation is needed. Ask any existing two way radio users how useful “open” communications are.
During a Push To Talk call the speech is digitized and sent over the network as GPRS data to the recipient, or more usefully, multiple recipients, so “group” conversations can be held anywhere there is phone coverage.
Be aware that this system is NOT a cheap alternative to standard tariff voice calls. It is aimed primarily at business users.
