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
but governments and more teaching insti-
tutions have to become more involved if
there is to be a reverse in the dramatic
shortage of RF engineers.
Public safety and that old chestnut
interoperability were topics that rumbled
on during the year and, while some
progress has been made, it is still an
On the technical front, the basics of
antennas were discussed as were the
effects of multipath fading, albeit at short
range on 2.4 GHz. A self-healing wireless
network in Darwin now uses 109 cameras
to gaze on about 6 km2 of the city and
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 Aus-
tralia 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 informa-
tion on the system and plan precise
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.

ad io commun ica t ions specialist Simoco proudly announces that its range
of Professional Radio equipment has gained P25 Compliance Assessment Program (CAP) approval, which ensures reliable and seamless communication across multiple vendors P25 radio equipment.Public agencies and emergency services organisations all require seamless and reliable infield radio communications. However issues can occur when agencies use a variety of equipment from different manufacturers, as they often use varied technical approaches or non-standard features, causing incompatibility.
This potentially compromises the success of communications in emergency operations.
Interoperability is a term that is commonly used by manufacturers referring to the ability of systems to work together. However until recently, no formal method of testing was available that would enabled P25 capable terminals to formally demonstrate their ability to interoperate with other P25 equipment vendors.
Project 25 (P25) CAP was established through a partnership between the US National Institute of Standards and Technology and the US Department of Homeland Security. This voluntary compliance program aims to provide emergency response agencies with a consistent and traceable method of gathering P25 compliance information on the products they buy.
It provides a means of verifying that dollars being invested in new equipment are capable of achieving standardised interoperable solutions.
The compliance allows P25 equipment to formally demonstrate interoperability and conformance with a select group of requirements, within the suite of the P25 standard.
The P25 recognition process requires radios to be tested in a P25-certified laboratory for specification compliance as determined in the TIA standard, as well as demonstrated interoperability with at least three other radio infrastructure vendors.
Interoperability testing was conducted on Simocos P25 SRM9000 mobile transceiver and the SRP9180 portable radio in both VHF
and UHF bands terminals with a Motorola, Harris and EF Joh
