It is traditional at this time of year to look back over the last 12 months and reflect on the progress of issues, the technology advances and anything else that takes our fancy. So here we go. It is good to see that the growing strength and influence of ARCIA is putting its weight behind education and training. Scholarships are a huge encouragement

TETRA transport trial completed
Public safety and that old chestnut interoperability were topics that rumbled
‘keep an eye’ on possible trouble spots. DMR, TETRA and P25 all had outings during the year. The DMR Association goes from strength to strength with new members and increasing influence, and a robust exchange of views between Australia and New Zealand further sharpened the views of some that TETRA can offer nearly everything that DMR can. On the P25 front, a new centre was opened in Sydney where both users and potential users can get detailed information on the system and plan precise personalised networks. No doubt these and other topics will spill over into 2012. But talking of this year, all of us at Radio Comms Asia-Pacific and RadioComms Connect would again thank you for your support during 2011 and, early as it may seem, wish you all a great Christmas holiday and New Year and we look forward to doing it all again in 2012.
