    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

    ongoing issue.

    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

    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.

    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
