Four of the big names in mobile telephones – Ericsson, Motorola, Sony-Ericsson and Siemens – have just announced that they are working on interoperability tests for push to talk systems. So where’s Nokia, pray?
Oh and I love the new acronym too – PoC (push-to-talk over cellular). I suppose that this is to differentiate it from push-to-talk over string and tin can.
‘The PoC function enables mobile phones to be used like walkie-talkies, providing communication at the touch of a button…Today, the industry leaders take the next step by successfully starting joint interoperability tests to help speed delivery of compatible PoC solutions to network operators.’
