INTRODUCTIONThe Wolfhound-PRO cell detector uses a narrow-band/high-selectivity receiver controlled by an on-board processor. The Wolfhound-PRO receiver has a resolution bandwidth of 4 MHz and uses a square-law detector. The receiver can be set to scan multiple up-link frequency bands assigned to North America, the European Union, Asia and Australia, as listed in Table 1:

The receiver detector output is used to drive one or more of the following indicators:

1. height of coarse and fine bar charts in the OLED display 2. pulsing rate of Laser (optional accessory mounted on DF antenna assembly) 3. pulsing rate of Sound Alert (speaker or ear bud) 4. turning on Vibrator Alert (fixed rate)

The Wolfhound-PRO unit is normally used in the hand-held mode either with an Omnidirectional antenna for cell phone detection only (see left side of Figure 1 below), or with a Direction Finding (DF) antenna for identifying the relative orientation (i.e. Line Of Position) of a radiating cell phone. Either antenna is connected to the Wolfhound-PRO unit RF coaxial port located at the OLED end of the unit as it can be observed from the two photos in Figure 1.

ResettingtheMaximum-HoldMarkerWhile in any one of the three monitoring modes (Phone Detection, Direction Finding or DECT 6.0Detection), clicking on the down arrow icon “-↓-” (the third icon from topon the right-hand side ofscreen)will reset themaximum-holdmarker“- -” (i.e., twodashesoneoneachsideofcoarsebar-chart)totheinstantaneoussignallevelonthecoarsebarchart.Intheabsenceofadetectedsignal,themaximum-holdmarkerwill typicallybe set to theambientnoise floor level.Generally, themaximum-hold marker is very useful for identifying azimuthal antenna orientations yielding maximum signalstrength(seesectionentitled“UsingtheWolfhound-PROunitwiththeDirectionFinding(DF)Antenna”.

AntennasTheWolfhound-PROunitcomeswithanOmni-directionalantennaandaDirectionFinding(DF)antennaassemblywithintegralpulsedgreenLaser.

TheOmnidirectionalantennaisamonopole,multi-bandantenna.Whenitisorientedvertically(i.e.,tipof monopole pointing straight up) the Omnidirectional antenna will detect signals with uniformsensitivityaround360azimuthdegreesinthehorizontalplane.SincethisantennawilldetectRFsignalsincidentfromanydirectioninthehorizontalplanewithuniformsensitivity,theusercannotdistinguishtheazimuthangleoftheRFsource.

GeneralGuidelinesforGoodSignalReceptionTheWolfhound-PROunitshouldbekeptataboutwaisttoheadheightfromthefloor,andawayfromwallsandobstructionsforproperperformance.Forthesamereason,keeptheWolfhound-PROunitatleast one foot (but preferably more) away from large metal obstructions or surfaces (i.e., reflectingmetal walls, heavy steel structural elements, metal-wire screens, etc.). The unit should not be usedwhile its antenna (either kind) is containedbybagsor enclosuresmadeofmetal, carbonorotherRFenergyabsorbingorshieldingmaterials;doingsowillseriouslydegradeitsperformance.ThesecriteriaarelistedinTable2below:

MonitoringCellPhoneUseinReal-TimeFor real-timemonitoring of cell phone use, observe the Coarse and Sensitive bar charts in theOLEDMonitoringscreen(seearrows(2),(5)inFigure4).

MonitoringCoarseScaleMaximumHoldTheCoarseScaleMaximumHoldmarker (seearrows1 inFigure7,8or14)representsthemaximumobserved level of the detector output signal since the last re-set of the Coarse ScaleMaximumHoldmarker register.TheCoarseScaleMaximumHoldregistercanbere-set to thenoise levelatany timewhileintheOLEDMonitoringscreen,bypressingthe“-↓-”button(arrow8inFigures7,8and14).

UsingWolfhound-PROUnitwiththeOmnidirectionalAntennaTo detect and monitor the existence of powered-on cell phones in a confined space, place theWolfhound-PROunitataboutwaist toheadheight fromthe floor,away fromwallsandobstructions.

27

Forbestperformance,theOmnidirectionalantennashouldbeorientedvertical(tipofantennapointingtoceilingorup)withrespecttothefloorplane.

UsingtheWolfhound-PROUnitwiththeDirectionFinding(DF)AntennaThe DF antenna enables the user to determine the direction in the horizontal (or floor) plane alongwhichthedetectedsignal ismaximum.Whenit ispracticalorappropriate,theGreenLaser(mountedon the DF Antenna assembly) may be deployed for assisting the user for aiming the DF antenna topotentialsources.TheimaginarylinealongwhichthesignalismaximumiscalledaLineofPosition.AfteraninitialLineOfPosition(LOP)isestablishedbya360degreesweepoftheunit/DFantenna,theusertakesa fewsteps intheLOPdirectionandthenre-confirmsthenewLOPorientationbysweepingtheunit/DF antenna back and forth about the initial LOP (see Figure 25), while observing the receiveroutputonthemoresensitiveDFScale.WhentheunitisorientedalongtheLOP,theDFbarchartwillalwaysindicateapositivereadingbetween0and1.AnegativereadingontheDFbarchart(between0and-1)meansthattheunitisnotorientedalongthelocalLOP.

2. Sweep theDFantenna in theazimuthaldirection, fromside to sidewithinanarcofabout90degrees (i.e.,45degrees to right, then45degrees to left,andrepeat…) todeterminerelativedirectionformaximumdetectoroutputontheDFbar-chart(seearrows4and5inFigures8and9).

29

3. WhiletheDFantennaispointingatthepotentialsource,re-settheCoarseScaleMaximumHoldmarkerbypressingthe“-↓-”button(arrows1inFigures8and14).ThiswillmaketheDFbar-chart read maximum level (i.e. 0 to +1 on the DF Scale”) to help the user make smalladjustments to his/her intermediate heading to “lock-in” on the actual orientation of thesource.

4. Walking slowly in the same heading, scan the unit again for maximum signal in the samemanner,whilethesignallevelregisteredonthecoarsebarchartincreases.

5. KeepwalkinginthesamedirectionandrepeatSteps3and4forincreasedsignaltillthesourceiswithinarm'sreachoftheWolfhound-PRO.

Method2:“Triangulate”withTwo(ormore)LOPsThismethod helps theuser rapidly “triangulate” theapproximate locationof sourcebydeterminingtwo(ormore)LOPsofthesourcefromtwo(ormore)positionsonthefloor(seeFigure27).

Once the approximate location is known, Method 1 can be used to “zoom-in” on the source, bymaximizingreceiversignallevel.Thefollowingsequenceisused:

1. ChoosePoint1anddetermineLOP1

2. Moveaway fromLOP1 in theperpendiculardirection toPoint2withoutgetting too close toobstructionsand/orwalls.AtPoint2determineLOP2.

3. Mentally determine approximate area of intersection for LOP1 and LOP2 within the spacemonitored.
