ON THE COVER

Communication is at the heart of effective team-

work and radio systems are central to the success

of many of the world’s greatest teams. Simoco

Xd digital mobile radio (DMR) networks make the

world of working together even easier, regardless

of team size, geographical spread or location.

A fully standards-compliant, end-to-end DMR

system with a range of portable and mobile

terminal equipment, Simoco Xd offers enormous

cost-saving advantages. The Simoco Xd base

station features Simoco’s unique switchless IP

distributed architecture, which removes the need

for expensive additional core network equipment.

Additionally, the same proven architecture also

offers users increased system resilience, as base

stations simply connect into existing IP ports and

require no additional IT equipment that could be

subject to failure.

As a team grows, a Simoco Xd DMR network

offers industry-leading network scalability, with the

simplicity of being able to just add base stations

to increase capacity. Plus, Xd bases offer the user

the convenience of a ‘software only’ upgrade to

a fully trunked DMR Tier III network.

Unlike other forms of digital trunking solutions

on the market, Simoco Xd DMR Tier III networks

are 100% ETSI DMR open-standards compliant

with no proprietary features, so interoperability

and flexibility are assured.

With a history of supply and deployment

of large-scale interconnected radio networks,

Simoco knows how to get teams talking to one

another. Simoco Xd DMR network solutions offer

all the benefits of both the DMR Tier II and Tier

III Trunking standards, plus Simoco’s unique re-

silient switchless architecture, allowing for optimal

network performance that can be relied upon.

Welcome to the first issue of Critical Comms,

formerly Radio Comms Asia–Pacific. Why the

change of name? Well, after a decade under

the old banner (and 15 years before that as

What’s New in Radio Communications), we

felt the magazine needed a new title to better

reflect the full scope of the industry’s activi-

ties and focus. Radio communications have

been undergoing rapid change, broadening

beyond traditional RF solutions and encompassing other business-

and mission-critical technologies such as IP and mobile broadband.

Critical Comms better encapsulates this progression and the ongoing

development of the public safety and critical communications fields.

We’ve listened to reader feedback, and that’s why in the magazine,

online and in our weekly eNewsletter, Critical Comms will deliver more

of what you want - more case studies, more in-depth articles, more

interviews with industry and regulatory leaders - while maintaining our

commitment to covering the latest product releases and critical com-

munications news.

For our advertisers, the evolution to Critical Comms provides an

even broader readership base that will reach more decision-makers

across the critical communications spectrum.

So no matter what field you’re in - emergency services, utilities, min-

ing and resources, oil and gas, transport, logistics, security, defence,

manufacturing or agriculture - Critical Comms is the industry magazine

with its focus firmly on supporting your business.

I and other members of the Critical Comms team will be at the

Comms Connect conference and exhibition in Melbourne in November.

Please drop by Stand 15 and say hello - we’d welcome the opportunity

to learn more about you and the work you do in your sector of the

critical communications field. And you can always get in touch with me

at my new email address (below).

MOBILEBROADBANDFORPUBLICSAFETYThe Australian emergency services sector is pushing the federalgovernmenttosetasidespectrumforpublicsafetymobilebroadband.



When it comes to spec-trumallocationformobilebroadband, which entitiesshouldtakepriority-com-mercialcarriers(whopay

big bucks to government for spectrumrights)oragencies thatprovideessentialpublicservices(whocan’t,andmanywouldsay shouldn’t, match what the carrierspay)? How can the needs of both usergroups be met?

At the recent ACMA Radcomms 2013conference in Sydney, Mark Burgess,CEOofthePoliceFederationofAustralia,forcefullyarguedthecaseforpublicsafetyagencies to be allocated a fair share ofspectrum for mobile broadband publicsafety communications - suchas theun-sold portion of 700 MHz digital dividendspectrum.

The following is an edited version of Burgess’s presentation.

In 2011,whengiving evidence to aUSSenateCommitteeonbroadbandspectrumforpublicsafety,NewYorkPoliceCommis-sionerRayKellytoldthecommitteethata16-year-oldwithasmartphonehasamoreadvancedcommunicationscapability thanapoliceofficercarryingatwo-wayradio.

In Australia there are around 400,000first responders across our public safetyagencies. Our roles are unique. Whensociety and nature are at their worst,police and emergency services need tobe at their best.

We believe our governments have anobligationtoemergencyservicespersonnelto provide them with the best equipmentand resources that will enable them todo their job effectively and efficiently,and to protect the public and each other.A mobile broadband capability fits intothat category.

Deloitte Access Economics, in a June2013 report, ‘Building our Nation’s Re-silience to Natural Disasters’, said: “…mobile broadband would achieve a moretimely assessment of incidents, more ef-fectivecommand,controlandcoordinationof activities, faster and more appropriateresponse to incidents that will lead to amore productive use of resources andimproved personal safety”.

The legislationWhentheKeatinggovernmentembarkedonradicalmarket-based reformof spectrumallocationin1992, it foresawthataprob-lem would arise, namely how to ensure

thatnon-commercialuserslikepoliceandemergencyserviceshadaffordableaccessto spectrum into the future. Recognisingthatthesenot-for-profitpublicsafetyagen-ciescouldnotcompeteinanopenmarketsystemagainstthebigtelecommunicationscompaniesforararecommodity,thegov-ernmentbuilt a seriesof safeguards intothe Radiocommunications Act 1992.

TheActspecifiesthatthesystemmustmakeadequateprovisionof spectrum forlawenforcementandemergencyservices.Parliamentwassayingthatspectrumhasapublicsafetyvalue,not justavalue forcommercial uses.

Charging for spectrum must also takeintoaccountthevalueofnon-commercialuseofspectrum.Inotherwords,thepublicsafetyagenciesshouldnotbeexpectedtopay the commercial rate for their spec-trum - the Act provided for spectrum tobe reserved for these essential publicpurposes so that they would not have tocompete at auction.

These safeguards need to be upheldtoday more than ever, as the big telcosvieforspectrumattheexpenseofpublicsafety and the public interest.

Itistheresponsibilityofthegovernmentand ACMA, under the Act, to ensure thatthe spectrum needs of law enforcementand emergency services are directly metandnottosendthesepublicsafetyagen-ciestodothebestdealtheycanwithoneormoreofthemajortelecommunicationscompanies at commercial rates.

Factors in valuing the spectrumThe Deloitte Access Economics reportindicated that the total economic cost ofnaturaldisastersinAustraliaaverages$6.3billionperyear, andthat this isexpectedto double by 2030, and to reach approxi-mately $25 billion by 2050. Of the costsofdisasterstogovernments,80%fallstothefederalgovernment.CurrentlyAustraliaspends $1 on pre-disaster measures and$10 on post-disaster recovery. MotorolaSolutions told the 2013 Parliamentarycommitteeon spectrum forpublic safety,that “every dollar spent on public safetyreturns $5 to the community”.

Deloitte Access Economics also saysa simple cost-benefit analysis showshow government funds would be savedby bringing forward investments in pre-disaster resilience measures. It wouldcome as no surprise that we consider

spectrum for public safety to be such aresilience measure.

Our view is that ACMA should takea whole-of-government approach whenmaking spectrum decisions. This meanstakingintoaccounttheserealcoststothefederal government.

Public safety mobile broadbandThere iscurrentlyanargumentabouttheneedforadedicatedpublicsafetymobilebroadband network. We suggest that thisargument has been had and resolved.

Two recent parliamentary enquirieshavecometoaunanimousandbipartisanviewthatadedicatedpublicsafetymobilebroadband network is the way forward.

In2011aSenateCommitteeinquiredintothecapacityofcommunicationsnetworksand emergency warning systems to dealwith emergencies and natural disasters.The committee recommended the Com-monwealthGovernmentallocatesufficientspectrum for dedicated broadband publicprotectionanddisasterrelief(PPDR)radiocommunications in Australia.

In 2013 the Parliamentary Joint Com-mitteeonLawEnforcementconductedanInquiry into Spectrum for Public SafetyMobile Broadband. That Committee hadas its chair the formerAttorney-General,Robert McClelland, who had also previ-ously been Minister for Emergency Man-agement. The deputy chair was SenatorFionaNash,DeputyLeaderoftheNationalintheSenateandnowAssistantMinisterfor Health. Other members were SenatorStephen Parry, Deputy President of theSenateandMichaelKeenan,thenShadowMinister forJusticeandnowMinister for

Justice who now also has responsibilityforEmergencyManagement. Itwasnotalightweight committee.

The committee made five key recom-mendations, including that a minimumof 20 MHz should be allocated to publicsafetyineitherthe700or800MHzband.

Whatbroughtthemtothatconclusion?When the committee did the analysisbetween a potential carrier model forpublicsafetyandadedicatedpublicsafetynetwork, there was only one conclusionthey could come to. Consider the follow-ing points:

•Apublicsafetynetworkhastobeabletodealwithavarietyofincidents,fromday-to-dayoperations,rightthroughtothose mission-critical events such asnatural disasters, major incidents andeven terrorist strikes.

•Thecarriers’modelisbuiltonrevenuegrowth and profits for shareholders,whereas the public safety model isbuilt on the premise of protecting lifeand property.

•The carrier’s model is designed fornormal day-to-day operations. Theirnetworkscanquicklybedegradedwithtrafficoverload,whereaspublicsafetyis built on my earlier premise - whensociety and nature are at their worst,public safety systems need to be attheir best.

•The carrier’s model is built on one-to-one communications; public safetyis one to many.

•Thecarrier’smodel isbasedprimarilyon heavy downloads whereas publicsafety will rely on heavy uploads.

•The carrier’s network is built to acommercial grade while public safety

needstobemissioncriticalhardened.•The carriers do not need to have the

security considerations that publicsafety requires.A further consideration is owner-

ship - what if the carrier were ownedbya foreigngovernment?Whatwouldbethe implications for the security of thenetwork?

A new governmentDidthefederalelectionchangeanything?We think not. If anything we think it’senhancedourprospectofgettingapublicsafety network developed.

In the lead-up to the 2013 federalelection,weposedthefollowingquestionto the major political parties: “The PFAseeksyourparty’scommitmenttoprovideaminimumof20MHzofthe700or800MHzbandspectrumforadedicatedmobilebroadband network for Australia’s publicsafety agencies so that inter-operablecommunications become a reality acrossthe nation.”

The Coalition gave a fairly detailedresponse, but the key point was: “If elected, a Coalition Government will conduct a rigorous cost-benefit analysis into the question of emergency services wireless communications and consider the most cost effective means of upgrading Australia’s law enforcement and emergency services mobile broadband network. The Coalition will con-tinue to carefully investigate this issue and seek to weigh the various competing public interests in consultation with stakeholders and State and Territory Governments.”

WewelcometheCoalitionGovernment’scommitment to conduct a rigorous cost-benefit analysis. We think that will playsignificantly in favour of public safetyagencies.

The cost-benefit research conductedby Deloitte Access Economics and oth-ers will be interesting reading for thenew minister.

researched eight economies in the Asia-Pacificregion-Australia,China,Indonesia,Malaysia,NewZealand,Singapore,SouthKorea and Thailand.

His policy findings are:•Onasocialcost-benefitbasistheben-

efitsofassigningbroadbandspectrumto dedicated PPDR services on anexclusivebasisfaroutweighthecostsas measured by opportunity cost.

•Thereisjustificationonacost-benefitbasis for allocating the spectrum thatis considered sufficient for nationalneeds. In all cases the cost-benefitanalysis seems to support a case forupto20MHzand,ineverycaseexceptSingapore,upto30MHzifnecessary.

•The decision would need to be basedupon a realistic assessment in eachcountryofwhatcontributionbroadbandwouldmaketoreducingtheriskofloss.

•Onacost-benefitbasistheopportunitycost is insufficient to justify market-based assignments of spectrum forPPDR purposes.What this means is that on a cost-

benefit basis, it is better to allocate 20to 30 MHz of spectrum for public safety

than to auction it to commercial carri-ers to achieve additional funds for theFederal Budget.

The Police Federation’s positionAs a result of our work, and that ofmany others, we’ve come to a numberof conclusions.

First,publicsafetyneedsmobilebroad-band communications. It is in the publicinterest. This must be a dedicated net-workcontrolledbypublicsafetybecauseourneedsaresodifferent fromthoseofcommercial networks.

Secondly,thereisasharedresponsibil-ity between the Commonwealth Govern-mentandstateandterritorygovernmentsfor emergency management. The federalgovernmenthasthespectrum;thestatesarepreparedtoinvestinthedevelopmentof the networks.

And remember, the states are notstarting with a blank piece of paper asmanyseemtosuggest-theyalreadyhavesignificant physical infrastructure thatthey would be enhancing. (Ericsson, initssubmissiontothe2013Parliamentary

Inquiry, revealed that theconstructionofphysical infrastructure by way of towersandsites-whichmanyofthepublicsafetyagencies already have - represents 80%ofoverallnetworkcosts,comparedtothe20% cost of equipment.) And the federalgovernmentwillneedaccesstothestatenetworksformission-criticalincidentsandmajor events like G20.

Thirdly,thereareseriousdoubtsaboutthe feasibility of public safety agen-cies roaming or overflowing onto publicnetworks during critical incidents. Whilea report on this aspect is due on thisshortly,manypeoplehaveadvisedusthattechnicallyit’spossiblebuttherewouldbeseriousflawsinsuchasystem.Flawsthatcouldjeopardisethesafetyofemergencyservices workers and the public. It is arisk,unlesswecanbeguaranteedother-wise, that we think is too great to take.

Thepossibility of commercial carriersor the NBN accessing the public safetynetwork when it is not in high demandshould be seriously considered as awayofensuringefficientuseofspectrum.Thecaveat is that the public safety agenciesmust have control of decisions aboutspectrum sharing.

What we don’t have agreement on yetis the amount of spectrum public safetyneeds,althoughtheJointCommitteecon-cluded that a minimum of 20 MHz isnecessaryanditwillcomeasnosurprisethat we agree.

If we’rejudged to have got it wrong, whoever isin the witness box at the inquiry will bein the loneliest place in the world tryingto justify their decisions.

Hosted VoIP/RoIP recordingElectrodata has announced the availability of a nationwide

voice recording solution for critical communications provid-

ers using VoIP.

The software solution does not require any new technology

and can be hosted on the client’s own virtual Server 2008

R2 and SQL 2012 infrastructure. The VoIP recordings can

be accessed via the internet with Electrodata’s thin client

Platinum Player. Advantages of VoIP include: no audio con-

version, resulting in less processing time, and easy access

to additional metadata.

A feature of the system is the separation of transmit/receive

recording for simplex transmissions, which boosts the clarity of

voice replay. Remote installation is possible even in complex

environments and is further simplified by the autodetection

of IP addresses.

Electrodata says this as an elegant and economic solution

for diverse and complex communication networks. Current

64-bit technology enables the high-performance solution to

capitalise on VoIP as a network communication standard and

eliminate many costly hardware components. An extension

to host in the cloud will be offered in the very near future.

99Handheld radar analyserAgilent Technologies has introduced a pulse meas-

urement option for its FieldFox handheld analysers

that is designed to further simplify radar field testing.

The pulse option enables users to carry a single

instrument into the field to verify and measure radar

pulse characteristics, S-parameters, spectrum analy-

sis and transmitter power. All measurements made

with FieldFox are consistent with those of benchtop

analysers.

The FieldFox pulse meas-

urement option efficiently

characterises radar

signal quality by

leveraging Agilent

U202x peak-power

sensors (available

in 18 and 40 GHz

models). Working

together, the pulse

measurement mode and

U202x enable mainte-

nance crews to check

radar signal quality without

having to carry a heavy benchtop instrument into

the field. With a single push of a button, users can

perform pulse characterisation in the field and obtain

all key performance indicators.

The FieldFox calibration engine now features ECal

module support, reducing calibration time and the

need to make multiple connections during testing,

while also providing for greater consistency between

measurements.

FieldFox analysers boast a number of features that

help simplify radar field testing. They include InstAlign,

a built-in spectrum analyser with time gating (Option

238), burst trigger and pre-trigger, and verification of

most RF pulse transmitters in the field.

Agilent also offers a suite of economical microwave

waveguide calibration kits to support C, X, Ku and K

band radar, satellite and microwave backhaul com-

munication measurements. The kits are suitable for

field maintenance and troubleshooting.

Reliable, robust communications - personal, industrial and governmental - have become an essentialpart of our society’s fabric. Hytera’s Peter Clemons argues that this trend will only increase, and thatthat’s a good thing.

Peter is renowned within the industry for taking a forward-looking approach to business and business solutions. We caught

up with him during his busy schedule and asked him to give usa forecast for the future of critical communications.First up, Peter, how did you get involved in critical communi-cations?Itwassucha long timeago that it is hard to remembernow. I’dstudiedandworkedasanacademicandeconomistinLatinAmericafor a number of years and then returned to Europe during the1990s, where I got involved in telecommunications and managedtocarveoutanichewithinthePMRsector,workingforanumberof TETRA manufacturers as well as helping out end users as aconsultant. TETRA was, and continues to be, my main focus andI was honoured to become a director and board member of theTETRA Association - now TCCA - in 2010, serving a two-yearterm before returning to consulting and then joining forces withHytera to develop the next generation of PMR solutions.

HOWEVER, THE SAFER OUR SOCIETIES

BECOME, THE EASIER WE TEND TO FORGET

HOW IMPORTANT PUBLIC SAFETY IS.

SAFEANDSECURE

Do you see critical communications continuing to grow?Duringthe1970sand1980s,landmobileradiowassynonymouswithmobilecommunications,beforethedaysofGSM.Nowadays,almosteveryone has an internet-enabled mobile phone, smartphones areeverywhere and we all depend on mobile applications during ourdaily life.Moreandmoreessential servicesaredelivered remotelyandvia smart mobile devices. I think this trend is irreversible andrequiresatotalrethinkofhowwemanagemobilenetworks,puttingcritical communications at the core of modern societies. The PMRcommunityhasa longhistoryofprovidingsecure,reliable,always-available services, so we must make sure we have a role to playin this mobile revolution.There are many options for businesses and agencies looking to adopt a critical communications system. Is TETRA still a force to be reckoned with?I have no doubt that TETRA will remain at the core of advancedcritical communications solutions for many years to come aroundthe world. There has never been a standard quite like TETRA andthere will probably never be another one like it in the future. Intoday’scomplex,increasinglyintegratedworld,nosingletechnologycan provide the full solution for professionals working in demand-ing environments but TETRA provides as much as 95% of thetotal solution today when TEDS (TETRA Enhanced Data Service)is included. Broadband solutions such as LTE can work alongsideTETRA to provide higher-speed data and video solutions for theforeseeable future.On the subject of broadband, do you agree with those who say that LTE will be the complete solution that everyone has been waiting for?There is no doubt that LTE will be a success. It would be naiveof me to suggest otherwise, considering the amount of resourcesbeing invested by major manufacturers, operators and developerswithin the global 3GPP framework. All major PMR manufacturers,includingHytera,arealsolookingathowwecanuseLTEtoprovidefaster data rates for our customers in the future.

However,LTEhasnotbeendesignedfromthebeginningtocopewiththedemandsofthecriticalcommunicationscommunitysoweneedtoremainengagedwith3GPPandthecommercialvendorsandoperatorsinordertocreatetheconsensusrequiredtodelivercriticalbroadband solutions in the medium term. As the concepts of ‘safecities’ and ‘safe communities’ develop during this decade and thenext, both the commercial and critical communications worlds willneedtocometogethertoguaranteehighlevelsofsecurityexpectedby citizens. This will take several years to achieve, so we will bekeptbusyandwillhaveto remainvigilant fora longtimetocome.Tell us about Hytera and how it is tackling the critical commu-nications future.Hytera is the fastest-growingPMRsolutionsprovider in theworld.This month we are celebrating 20 years in the industry and therewill be a big birthday party in China.

Electrical energy loggerThe Fluke 1730 Energy Logger is a

streamlined energy logging tool with

a straightforward, intuitive design - it

lets technicians load studies and en-

ergy logging right out of the box. The

results provide facility managers with the

information necessary to identify and prioritise energy-saving projects.

The logger conducts key measurements of voltage, current, power

and power factor to identify areas of energy waste. All measured

values are logged automatically and can be reviewed during logging.

Common set-up errors are rectified, through re-engineered cables,

digital check and auto-correct of all connections and an on-screen

wizard for interval set-up. It has the highest safety rating in the industry

(600 V CAT IV/1000 V CAT III), can be powered directly from the meas-

ured circuit (eliminating the need to find a power outlet) and has two

USB ports for fast data downloads to PCs or standard thumb drives.

Data logged can be imported into the Fluke Energy Analyse software

for further processing and archiving. The software lets users analyse

energy or load profiles including: zoom-in and zoom-out on details;

add comments, pictures and other information to data; overlay differ-

ent logging sessions; create reports and export measurement results.

PIM test analyserThe MW82119A PIM Master

was launched in Decem-

ber 2012 as a high-power,

battery-operated passive

intermodulation (PIM) test

analyser. At launch, six fre-

quency options were available

covering the LTE 700 MHz,

Cellular 850 MHz, E-GSM

900 MHz, DCS 1800 MHz,

PCS 1900 MHz and PCS/

AWS 1900/2100 MHz bands.

A n r i t s u h a s a d d -

ed three frequency options for the product fam-

ily, covering the LTE 800 MHz, UMTS 2100 MHz and

LTE 2600 MHz frequency bands. According to the GSMA,

these represent three of the top five bands that will be

used for LTE network deployments globally. LTE requires

low noise levels to achieve maximum data throughput, so

it is critical that PIM interference be eliminated. With its

enhanced portability and Anritsu’s patented Distance-to-PIM

(DTP) technology, the PIM Master is a suitable tool to help

operators eliminate PIM and maximise LTE performance.

Keeping a city energisedCase study

OneofthelargestenergycompaniesinSeoul,SouthKorea,urgently needed to replace its legacy communicationscontrolsystemwitha21st-centurysolution.

To call Seoul, South Korea, a megacity would bean understatement - it’s the world’s second largest metropolitanarea, with a population of 25.6 million people. More than half ofthe country’s residents live in Seoul.

Those residents need a lot of energy, including natural gas.Samchully City Gas is a natural-gas distribution company thatservesSeoul,supplyingnotonlyliquefiednaturalgastoresidentialand commercial customers, but also the gas that fuels the city’ssteamsupplyandpower-generationsystems,fuelcells,cold-andwarm-water supply systems, and even the city buses.

This included capabilities that would allow them tocombinemultipledevicesandresourcesintoasinglesystemandprovide a graphical user interface to control them all.

The situation became morepressing when the need arosetousemultipleiDENdevicesonthe system; the existing equip-ment could support only onesuch device.

Samchully began searchingfor a vendor to help it obtain,design and implement a newcommunicationssystembasedoncurrenttechnology.Afterconsid-eringanumberofproposals,theyawardedtheprojecttoHanswell.

Based in Seoul, Hanswellprovidestwo-wayradioequipmentand RoIP, dispatch and intercomsystems to public- and private-sector clients throughout SouthKorea and Asia.

Hanswell Vice President Sebastian Beck explains some of themostcriticalfactorsthatcontributedtothecompanybeingchosenfortheproject.“Notonlyhavewehadalong-standing,positiveandsuccessful business relationship with Samchully over the years,”says Beck, “but our proposal was based on Zetron’s DCS-5020Digital Console System. The DCS-5020 would be able to providethe centralised, updated and improved functionality Samchullywas looking for and would more than fulfil their requirements ofthe project.”

Integrated communications systemThe Exelis C4i SwitchplusIP communications system delivers seamless integration with the latest

TETRA infrastructure. It provides control room operators with a new level of situational awareness

over their deployed personnel, which greatly improves the safety of workers, increases visibility

and adds flexibility for operational customers.

SwitchplusIP provides operators with command, control and communication over both digital and analog

radio systems, along with comprehensive telephony services and access to a range of additional features.

Man-down alerts and emergency alarms are fully integrated, and mapping functionality with an innova-

tive communications overlay gives operators pinpoint locations of emergency alerts.

Radios can be mapped and tracked, either as talk groups or individually, and can be followed live on-screen, enabling

operators to establish one-on-one direct calls to a subscriber with a single button press. Enhanced radio call features,

such as on-hold, transfer, conference and patching to telephony and other radio standards such as P25 and conventional

are supported. Increased visibility of assets is achieved through the additional information that can be reported over the

air to operators, such as display of the calling party radio ID.

The system provides cost savings to network owners by enabling digital network upgrades to be phased in, as all of

the above features are available via a single integrated user interface that provides full access to both the new digital and

the legacy analog systems simultaneously.

Satellite RoIPIn remote field work, VHF and UHF have always had inherent

coverage limitations. But today, operators can have a radio IP

network via satellite that solves many coverage problems.

AST Australia has focused its efforts on providing satellite

comms-on-the-move with radio IP connectivity. In collaboration

with Cobham, a new mobile satellite L-band solution has been

developed that provides a basic fist microphone PTT solution that

can operate either in a moving vehicle/vessel or at a fixed location

using both GSM and satellite connectivity.

The Cobham Explorer PTT is a purpose-built L-band satellite

RoIP solution designed to be bandwidth efficient on the Inmarsat

network to provide a global solution. Additionally, there is the

advantage of using GSM when available (there are ports for two

GSM dongles), which is said to provide a true least-cost route

between mobile and satellite.

Also provided is a 4-wire ear and mouth solution, with which

operators can add existing radio infrastructure and connect vari-

ous nodes to essentially become a bridge, a repeater or a simple

PTT device. In fact, the vehicle itself can become a mobile radio

repeater to reach all users within range.

The intelligent fist microphone lets users select predefined user

groups on the fly. It can also record the last five voice messages

received, allowing for instant replays. This feature is expanded

in the server providing a full audit trail. A console is available to

manage the user groups from head office. The solution can also

provide real-time tracking, a second dedicated voice line and

internet broadband access.

Multifunction calibratorFluke Calibration has introduced the 5730A Multifunc-

tion Calibrator, designed for calibration professionals

who require the most accurate dc/low-frequency

signals available in a multifunction calibrator.

The device builds on the 5700A/5720A with

improved accuracy, new digital components and a

large full-colour, touch-screen display. The display

brings all of the calibrator’s status and settings into

one location, making any operation accessible with

the touch of a finger. For laboratories running their

existing 57XX calibrator under remote control, the

5730A can be set to run in 5700A/5720A emula-

tion mode, eliminating the need to rewrite system

software or procedures.

The calibrator also improves upon the perfor-

mance of the 5720A in ac current, ac voltage and

resistance functions. Specifications are absolute,

stated in 99% and 95% confidence intervals,

traceable to international standards via ISO 17025

accreditation and include the uncertainty of the

calibration standards used, so no additional analysis

is required.

The device features artefact calibration, which

transfers the assigned value of an external artefact

to a large array of multidimensional parameters

within the instrument. The calibrator can fully adjust

itself using only three external standards and the

calibration process takes only about an hour as

opposed to several hours using traditional methods.

Quadband antennaThe G Spotter Omni Quadband ‘Hard

Hat’ antenna has been designed with

emergency services vehicles in mind, with

a single low-profile antenna providing four

different outputs in a single unit.

The antenna has two 850-900 Mhz cables enabling

current 3G and the soon-to-be-activated Telstra LTE MiMo recep-

tion, as well as a single 2.4 GHz Wi-Fi cable and a separate

UHF cable (that can be customised to any suitable frequency).

The randome is made from a tough fibreglass that is very

robust. The design can be fitted to larger emergency vehicles,

in particular rural fire tankers, where traditional whip antennas have

a high rate of damage.

Field testing has shown that there is no interference or loss of

performance when transmitting a UHF signal and concurrently utilis-

ing 3G wireless broadband and at the same time creating a Wi-Fi

hotspot inside the vehicle.

The antenna also creates a large area Wi-Fi hotspot outside, ena-

bling meshing of Wi-Fi across vehicles as well as data bonding for

greater bandwidth throughput and GPS tracking as future possibilities.

Wireless headsetThe XBT heavy-duty wireless headset is a digital headset

for MotoTRBO radios that shields users from harmful,

high-decibel noise while letting them hear the sounds they

need to, such as voices, alarms and alerts.

The XBT Headset features patented SENS technology

that combines advanced speech enhancement with ex-

treme noise suppression. SENS recognises speech and

elevates it so you can hear what others are saying. And

it recognises high noise and suppresses it - from arc

welding to sandblasting.

The XBT limits in-ear exposure to 82 decibels and protects

from all types of noise, including impact, intermittent and

continuous. Most importantly, users retain 360° situational

awareness so that surrounding sounds can be heard - from

co-workers conversing to equipment rolling up.

The XBT is compatible with MotoTRBO radios operating

in analog or digital mode and connects with Bluetooth

functionality (built in or with Operations Critical Wireless

adapter). It features a PTT button on the earcup and has

22 h of battery life.

Communications systemOperators looking to establish an effective means

of communication often have to implement a com-

bination of technologies, including HF, VHF, UHF,

CB, satellite and/or cellular in order to minimise or

eliminate the possibility of employee isolation during

an emergency event. However, this ‘communications

abundance’ comes at a cost for any organisation

to implement, manage and, in particular, train their

employees to be proficient when operating these

potentially life-saving devices.

In 2014, Nexion Data Systems will launch its

NX6900 Unified Communications System aimed

directly at minimising or eliminating the technical

and training nightmares associated with numerous

in-vehicle communications technologies, by unifying

the audio, messaging, mobile data and GPS features

of up to four attached (vendor-independent) devices.

Handheld CB radioGME has introduced the TX6500S 5W handheld UHF CB radio,

designed and manufactured in Australia, featuring ScanSuite

and DSP. IP67 rated, it has a die-cast aluminium chassis and

can operate in temperatures from -20 to +60°C.

The TX6500S features ScanSuite, a technology that GME

says scans twice as fast as other UHF CB, resulting in unin-

terrupted conversations with a group of like radios, and skips

nuisance signals while continually scanning memory channels.

The TX6500S radios are a robust communications solution

when managing team communications in a business environ-

ment but are equally suitable for camping, touring and 4-wheel

driving. A comprehensive range of aftermarket accessories

provides multiple charging options, hands-free communication

choices and radio protection.

Digital signal processing measures, filters and compresses

standard analog radio signals and converts them to a digital

format, eliminating much of the conventional processing and

time-consuming manual alignment.

Advanced signal management (ASM) identifies interference

caused by strong local signals on adjacent channels and

prevents these from opening the squelch control. ASM also

minimises distortion of reception by finetuning the receiver

frequency to match that of the incoming signal.

Dynamic volume control automatically compensates for vari-

ations in received audio level and, when activated, provides

a constant audio output level, enhancing quality of reception

and the simplicity of use.

Other features include: five extra programmable receive

channels with alpha labelling; SelCall; CTCSS; DCS; and voice

inversion scrambler.

Signal and spectrum analyserThe R&S FSW67 high-end signal and spectrum analyser covers the

frequency range from 2 Hz to 67 GHz in a single sweep, simplifying

test set-ups. It does away with external harmonic mixers and there-

fore does not require complex cabling. Image frequencies and other

spurious emissions caused by harmonic mixing are suppressed. With

its analysis bandwidth of up to 320 MHz, the FSW67 also measures

wideband, hopping and chirp signals.

As users can perform spectrum measurements and modulation

measurements in the 60 GHz band, the FSW67 is not suitable for the

development, testing, verification and production of transmitters and

components for radar applications, satellite and military communica-

tions systems. The analyser also provides valuable assistance when

performing development tasks relating to fast wireless communica-

tions based, for example, on WiGig (IEEE 802.11ad) or WirelessHD.

The integrated multistandard radio analyser (MSRA) measures spec-

trum and modulation parameters of signals with different modulations

simultaneously and also correlates these signals in time. With the

MSRA function, users can efficiently analyse how and why different

signals affect each other. The 12.1″ (31 cm) touch-screen interface

makes operation very convenient, especially for complex measurement

tasks. The MultiView function allows users to simultaneously display

multiple measurements and applications.

scalability and usability. It is designed to streamline the console operator’s job and help him or her focus on the incident or

task at hand. It is also designed to meet the needs of the full range of other personnel who interact with the system, includ-

ing administrators, supervisors, and radio and IT technicians.

The system’s features and functionality include: the use of standards-based IP protocols ensuring the system’s compatibility

with commercial, off-the-shelf (COTS) IP network devices; support for off-site access for remote maintenance and operation;

dual end-to-end network option that allows fully redundant IP networks.

The system is scalable from a single LAN configuration to a multi-node, geographically diverse WAN configuration. The

system’s analog and digital radio gateways interface to a wide range of conventional and trunked protocols, both manufacturer

proprietary and open standard, all of which can reside on a single system.

MAX Dispatch supports patching and conferencing among multiple resources. IT-EZ continuously monitors network perfor-

mance, keeping users and technicians apprised of network conditions. One-click operations and intuitive UI give operators

immediate access to information and controls.

GUNS,MINESANDLTELTEisquietlygainingafootholdinnon-traditionalareas.Tolearnwhy,JonathanNallyspokewithSimonLardnerfromChallengeNetworksandfoundoutwhyhisteamssometimeshavetobeaccompaniedbyarmedguardspackingUzis.

Whichtechnologyisbestforyourcriticalcommunica-tionscircumstances?IsitTETRA,P25,dPMR,DMR,LTE?Inmanycasesthechoicemightbeobvious,butinothersnotso.Accordingtosome,LTE-tradition-allyaconsumer-orientatedtechnology-couldbethe

elephant in the room.Challenge Networks has installed 2G, 3G and LTE mobile phone

networksacrossthePacificand isnowmoving intotheminingsec-tor inAustralia.

Lardner will present a case study on LTE for major resourcesprojectsattheCommsConnectconferenceinMelbourneinNovember.He’ll also take part in one of the workshops (mobile broadband andLTEforcriticalcommunications)thedaybeforetheconferencebegins.What sort of work does Challenge Networks do?Historically, we’ve built mobile phone networks for typically smallcountries, such as islands in the Pacific - Fiji, Vanuatu and so on.We are probably one of only two companies in the world that doesthat; it’s fairly specialised.

We’re now moving more into the mining segment, which kind ofmakes sense - mines are like very small countries, like an island Iguess.They’retypicallyinthemiddleofnowhere,oftenwithreasonablydifficult climatic conditions. So we’ve gone from being in traditionalcarrier networks and now moving into the mining segment. And mypresentationwill beon someof the challenges youhave in buildingsmall networks.So what are some of those challenges?It’s mainly about money. Anyone can develop anything - it’s makingit cost-effective that is the key thing. But the mining segment doeshavesomespecificneeds.Mostmobilenetworks, intheLTEtypeof

space,attheendofthedayarestilldesignedforconsumers.They’renot exactly designed for true industrial applications.

The trick is to get what is historically a consumer network towork in an industrial sense, and that’s mainly about reliability andruggedness.So you only handle LTE? You don’t get into TETRA or other systems?No,we’reveryspecificallyintheLTEspace.We’renotanITcompanyand we’re not a comms company in the TETRA, P25 sense. We’reessentially a telecoms company that is jumping market segments alittle bit.Do you work through subcontractors or do you get your hands dirty on the ground?Weprettywelldoitall,andthat’spartiallyduetothelegacyofwherewe’ve come from. We tend to work in island nations, so we fly ina bunch of guys who basically do everything, although we tend nottodopurecivilworks,becausethat’ssomethingthatcanusuallybedonemoreeconomicallybysomeonelocally.Similarlyinaminesite,typically there’s someonealready in theminewhodoescivilworks,and they’re thepeople youwant toworkwith.Which island nations have you worked with?Mostof thePacific includingKiribati,Vanuatu,PNG,Fiji,SamoaandTonga. We have also done some work in Asia and Africa. I just gotbackfromKiribati,wherewe’reinstallinga3G/LTEnetwork.They’reverychallengingplaceslogistically,becauseifyoudon’tgetwhatyouneed on the boat this month, you have to wait for perhaps anothereightweeksforthenextboat.ButforsitesinAustralia,typicallythereis a daily road train delivery going to the mine. So while it is a bittrickygettingstufftotheseAustralianlocations,it’snothingcomparedtogettingabasestation intoKiribati.


And I imagine that LTE would give you lots of other benefits, such as being able to use normal mobile phones on the network as well?Comingoutoftheconsumerspace,yougetawholebunchofthingsfor free, as it were. And one of those is that there is a variety ofCPEs.Soyouhavethingsfroma$5000industrialmodeminstalledina$10million truck todo telemetry, todownat theotherendwhereyou have a $29.95 dongle that people use to surf the web at night.Andall of themworkon the samenetwork.

Andsothat’swhereIguessLTEhasitsplace.Itenablesyoutobeinvolvedinaportfolioofservices. It’snotasinglegame,soyoucanuseLTEforthingsliketalkingtoeachother-standardvoicecomms.Andthenmovingthroughthecontinuumyouhavedataservices-sobeingabletoknowwhereeverytruck inthemine is.Thenyouhaveconsumer applications, where people can use their PCs around themineand in dongasat night.

And these things become more important as the mine becomeslarger.Forexample,alargeminemaybe35by35kilometresinsizewithacarspeedlimitofabout25kilometresperhour.Sotogetfromwhereyoustayatnighttowhereyouworkcantakeyouanhour.Soif you have a meeting down at the other end of the mine, this canleadtosignificanttime losttotravel. Ifyouenablesomethingsimplesuch as mobile videoconferencing between people at opposite endsof themine, therecanbesignificant lost labour savings.And that’s an advantage of LTE over, say, P25 - the ability to broadband?The disadvantage of P25 and TETRA networks is that they haverelatively lowbandwidth.They’remainlydesignedasvoicenetworksbasically. The handsets are also often quite expensive and haverelatively limited voice capabilities - certainly compared to modern3GorLTEnetworks.

TheadvantagesofP25andTETRAarethatthey’refairlyreliable,andyoucando things likegroupcalling.

LTE networks can now do all those things as well, especially ifyoubuildthemspecificallyas industrialnetworks,which iswhatwedo.Sowecandogroupcalls for anyoneandeveryone in themine.But youwouldnever do it in a consumernetwork, because it couldkill thenetwork ifyouwerenotcareful.So ifyoubuildanLTEnet-work for amine, youneed tobuild it so it is essentiallybulletproof.Has your experience working in difficult island environments helped you to get the mining companies on board?From our experience in working in countries like PNG, we had anunofficialcompanymotto: Ifyou’renotbeingshotat, it’sagoodday.And in some places in PNG there can be real safety concerns. Sowhenwefirstwenttothemines,theysaid,“Youcannotdomines,youdon’tunderstandhowroughitis.”WethenexplainedhowinPNGweworked with people who had Uzi machine guns for protection - sowewereused toworking in challengingcircumstances.

Sounlesstheminesstartfiringatuswithsemiautomaticweapons-which iswhathashappenedtous insomemarkets-we’reprettyhappy. Or unexploded ordnance, such as we found in the SolomonIslands.You’ddigahole in theground tobuildabasestation towerandfindmortars fromWorldWar II.Sowhile theminingsegment istough, it’s not that bad!Challenge Networkswww.challengenetworks.com.au

What is your impression of the future of LTE?There are a couple of aspects to it. One is that many people havea lot of investment in a number of technologies, and there’s a hugelegacy in those. I thinkLTE is justanother inclusion intotheportfo-lio of things you can use. Emergency communication at one end ofthecontinuumstartsathandsignalflares. It thenmovesonthroughsystemssuchasTETRAandP25,andLTEisjustanotherone.Idon’tthink LTE is the salvation of the world, its just another technologythat canwork in someapplications.

IthinkoneofthevalidcriticismsofLTEintheemergencycommssector is that it is designed for consumers. And that’s what I’ll betalking about at the conference - it all depends on how you buildthenetwork.So you can build an LTE network that’s more ruggedised for strin-gent applications?That’sright.Becauseofourexperiencebuildingconsumernetworks,we’velearnedwhatworksandwhatdoesn’t.Butaconsumernetworkis still a consumer network - if you’re building an industrial LTEnetwork, that isacompletelydifferentanimal.Oneofmykeypointsis that the mistake that some people make is saying that consumerand industrial networksare the same thing, and they’renot.

There are a number of things you canuse LTE for.Oneof themisasareplacementforwherepeoplehavebeenusingWi-Fi.Sooneplace where LTE is more likely to be used is the mining segment,in physically large mines, because the big thing that LTE has up itssleeve is that a base station can cover up to 30 or 40 kilometres,whereasWi-Ficancover100-200metres.Sowhenyoustarttolookattelemetryandthingslikethat,whichhavetraditionallybeendoneonWi-Fi,LTEisawholenewgameanditcanbealotcheaperthanWi-Fi.

Emergency call softwareRohde & Schwarz has reached a mile-

stone in the introduction of voice over LTE

telephony for the IP multimedia subsystem

(IMS). The company has verified test cases

for IMS emergency calls over EPS/EUTRA in

compliance with GCF Work Item 154.

All mobile phones and smartphones must

be able to place emergency calls, both in their home

network and in other networks - even without a SIM card. The correct

signalling of an emergency call is crucial in an emergency.

In cooperation with leading chipset makers, Rohde & Schwarz has

verified test cases defined in GCF Work Item 154 for IMS Emergency

Call over EPS/EUTRA. The R&S CMW500 multi-RAT protocol tester

was used to test the RRC connection set-up for an emergency call

and the IMS emergency call registration.

Rohde & Schwarz says this is a key step in the transition toward

pure LTE networks. In the past, placing emergency voice calls on LTE

networks was especially challenging for network operators, chipset

makers and consumer electronics manufacturers.

The R&S CMW-KC504 IMS emergency call over EPS/EUTRA software

option is available for the R&S CMW500 multi-RAT protocol tester.

Mobile TETRA systemDAMM’s Rapid Deployable TetraFlex (RDT) from GMG Solutions has been designed for first-responder

emergency and security services. Housed in a tough wheeled suitcase for maximum mobility, RDT

offers a fully functional high-powered TETRA system that can be instantly deployed in emergency

situations - such as road accidents, natural disasters or SAR operations in remote areas - regardless

of whether there is any existing network in the area.

RDT enables first-responder emergency or security services to instantly set up a fully configured

communications system on site, which can then serve as a temporary command centre for users in the field.

RDT also supports important security applications, such as temporary deployment during VIP visits or special conferences.

The system has been designed to meet the highest security, safety and reliability requirements.

RDT comes with its own integrated power supply or can be powered using the 24 VDC socket of any car, truck or other

vehicle, and can also be connected to solar-powered devices or to a 230 VAC generator.

RDT is a highly flexible modular system - several cases can be linked together to create a multisite configuration using

secure IP protocols. The system can also perform group calls to any other TETRA network or even to analog networks, re-

gardless of manufacturer. It comes with a full range of advanced software tools and can also be connected to an advanced

dispatcher solution with a GPS positioning system.

Mobile surveillance systemThe Mobile Surveillance System

(MSS) is a scalable system

comprising mobile, solar-

powered camera sites with

radio and telemetry links to

trailer-mounted bases. Typi-

cal applications are for security of mine sites and ad hoc deployment for crowd control.

Currently deployed over an area of operations exceeding 70 km square and in some

cases with links exceeding 100 km, the MSS is protected and capable of deployment in

extreme weather conditions of wind, sea mist, temperature and with an associated highly

corrosive atmosphere, which would attack and corrode deployed devices if poorly conceived.

The radio links are based on DVT-B digital TV standards for high-quality video transmis-

sion and utilise COFDM digital technology to allow the cameras to be repositioned at will

without suffering signal degradation common in both opencast and underground operations.

The use of digital transmission opens up new opportunities for the operator to use the

radio backbone to transmit GPS location data for vehicles within the area back to the

control room. There is also the ability to mount cameras on vehicles and transmit this

video back to the control room also.

Althoughtechnicallyexplicitbeamformingwasdefinedin802.11n,it was not implemented because the specification provided theflexibility to implementbeamforming inmultiplewaysandvendorsdid not support multiple mechanisms due to the implications forproduct costs.The802.11ac specificationsaddress this bydefininga single beamforming mechanism.

Explicit beamforming requires the beamformee or the client toprovide explicit feedback regarding the channel conditions to thebeamformerortheAP.Thebeamformerthenusesthisinformationto generate beams toward the beamformee.

The advantage of beamforming is that it increases the rangeat which the higher data rates can be attained. The advantage ofexplicit beamforming defined in 802.11ac over the implicit transmitbeamforming implemented in many of today’s 802.11n productsis twofold. First, because it is based on channel conditions, thebeamforming should be more accurate and result in a strongerreceivedsignal.Second,becausevendorsarealignedonacommonmechanism it can be used for transmitted and received signals.

84Signal generatorThe Rohde & Schwarz SMW200A generates RF and envelope signals in real time in a single instrument, to enable testing of envelope

tracking performance of power amplifiers.

The high-end vector signal generator has been enhanced by adding the R&S SMW-K540 option for envelope tracking. This option

enables quick and easy testing of envelope tracking power amplifiers for smartphones, base stations and tactical radios.

The device meets the test requirements of chipset manufacturers by offering a solution that generates fully synchronous RF and

envelope waveforms in a single instrument. Users can delay the RF waveform and the envelope waveform relative to each other by

±500 ns with 1 ps resolution. Due to its performance characteristics, the device delivers an extremely low-noise envelope signal at

the analog baseband outputs. The signal generator calculates the envelope waveform from the baseband signals in real time, so

that all communications standards supported by the signal generator as well as custom waveforms can be used. A large selection

of flexible shaping functions allows users to optimise the envelope in real time.

The envelope tracking parameters can be configured on the generator’s straightforward graphical user interface. Automatic en-

velope voltage adaptation is available to speed up set-up and testing time since the main parameters such as VCC voltage range,

PAin range, DC modulator gain, DC offset and power offset only need to be entered once. Automatic recalculation of the envelope

based on the power amplifier input level makes it possible to perform power sweeps over the amplifier’s entire input range.

A key national resource

Chris Chapman is the Chairman and CEO of the Australian Communications and Media Authority.

I am delighted to contribute to the inaugural issue of Critical Comms and welcometheopportunity tohighlight someof the important spectrumworkbeingdeliveredbymy agency, the Australian Communications and Media Authority (the ACMA).

IappreciatethatIamspeakingtoaconvertedaudiencebutitcannotbeoverstatedjust how crucial a resource spectrum is. It is one of the great enablers of the 21stcentury, a century increasingly being driven by technological innovation. Spectrumdoes not just facilitate communication; it has changed the very concept of how weinteractwiththeworldaroundus.Thistransformativecapacity isnotsomethingthatany of us, least of all regulators, can take for granted. Management of this finitenationalresourcemateriallycontributestoourregion’sfundamentaleconomicgrowthand social development.

I am proud of the high-quality outcomes that have been produced.

However, there isno timetostopand rest.TheACMA’sspotlighthasnowshiftedfrom the reallocation of the digital dividend to identifying mechanisms to meet theever-increasing demand for spectrum to enable participation in the digital economy.Developments intechnologyhavetransformedthewayweconductmostpartsofourlives.Useof spectrum is no longer intermittent anddiscrete.Our devices -whetherpersonal (like smartphones and pacemakers), private (like smart meters and assettrackers) or public (like disaster warning systems) - are now always on.

There are a number of key implications of this seemingly relentless growth indemand for spectrum. We need to continue to seek and implement improvements inthe efficiency of spectrum use (and Australian industry and researchers are greatinnovators in this field). We need to continue moving spectrum to its highest valueuse as this changes over time, recognising and valuing the diverse range of mon-etary and non-monetary contributions that users of spectrum make to the Australianeconomy and society more generally.

The ACMA continues to critically evaluate demand and the need for spectrumacross all sectors to better understand the complex and dynamic interaction of so-cial, economic and technical factors that drive spectrum requirements. To this end,we have commissioned two bodies of research - Spectrum Demand Forecasting forWireless Access Services and the Economic Impacts of Mobile Broadband.
