One of the important aspects of an open standard is the ability to rigorously test it for interoperability. And then when you’re done testing – test yet again. It is an ongoing process that never seem to end.

Take our 3G-324M AG at the IMTC – I’ve been an active participant of this group from its inception, and that was over 5 years ago. And this year, the 3G-324M AG is going to have some more testing done – it seems like there is no rest for engineers.

So now that the GSMA has decided to go full force and work on the VoLTE specification so that operators can start rolling out all-IP mobile networks and still provide the basic services they do today, there was a missing piece in the puzzle – they have the ecosystem, but not real place to use for interoperability testing amongst the vendors implementing VoLTE.

That’s exactly where the IMTC comes into the picture [Read more...]
