Not a system fault – this is how GSM phones work when on a call

15. Analysing Printout  Prisoner making one call The system will detect 3 events  Initial registration of the phone  The call itself  The turn off notification  Prisoner texting The system will detect 2 events for a single text  The incoming /outgoing SMS message  The response – usually within a few minutes  In both the above, group events according to detected signal strength as this is an indication that events may have come from the same phone  Short duration calls indicate that the BTS has instructed phone to reduce power resulting in a loss of detected signal by a CPD351

16. CPD351 Remote Detector  Detection ranges (free space):  GSM up to 300m  UMTS 2100 –approx 80 to100m  Maximum power for a 3G class 3 phone is 250mW typical output can be <10mW in strong areas  Battery life (internal) 3 to 4 days  Anti-tamper facility  Prison radio interference suppression (400-500MHz)  Enhanced GSM detection algorithm for calls  Can control other devices e.g. low powered jammers, audio recording equipment etc.  Ideal locations – Service Cupboards (with wooden doors)

17. Typical HMP wing layout

18. Deploying the CPD351  Deploy 1 unit per wing initially with sensitivity setting =9  Gather information for approx. 1 week to map the type of phones in use (2G/3G) and how they are being used  When using multiple detectors in a wing, reduce sensitivity so detectors cover separate areas.  Use directional antennas to monitor specific areas.  When moving detectors to new locations-press the Test button on the unit so printer records the event.  If strong external GSM signals being detected, sensitivity can be further reduced via rear switch-UMTS sensitivity unchanged

19. SDA351 Directional Antenna Specifically designed to enhance performance of the CPD351 Directional – 60º wide sensitivity beam* * applies to GSM1800 and UMTS only, GSM900 is less directional Increased gain at 1950Mhz for better 3G detection SA918 Antenna Same antenna as used with GSM196 Directional -60º wide sensitivity beam * applicable across all bands Small size aids deployment

21. Monitoring of a wing using two units S=9 S=2 05:48:23D016GSM net/SMS 00m04sS=9 05:48:23D044GSM net/SMS 00m04sS=2

26. CPD391 Repeater  Designed to pick up and re-transmit CPD351 signals  Detected signals validated before retransmission  Use the same transmit frequency as CPD351 units  Allows detector signals to be collected from a shielded building / wing and retransmitted via an external antenna. Typical location –roof spaces

27. CPD392 Trunk Repeater Admin Building and security office Workshops, Gym and Canteen Facilities CPD392 CPD391 CPD351 Detectors deployed in wings Accommodation Block Only transmissions from other CPD391 repeaters are recognized 20:34 D016 GSM net/SMS 00m04s S=7 CPD351 (D016) transmissions screened by workshops

28. GSM196 Handheld Cell-phone Detector  Detects both 2 and 3G phones.  Range better than 400metres to a 2W source (GSM900)  Imbedded filters to restrict detection to Handset frequencies  LED Bargraph signal level indication  Automatic Brightness Control  Feature requested by prison security officers  Unique Signal Analysis for accurate detection  Cadenced vibration alert for covert operation  Ease of Use  Single button operation  Directional antenna option  SA918 antenna allows accurate location of a target and increases range

29. GSM196 + directional antenna option GSM196 + directional antenna option Detection area primarily restricted to ± 30º both in the horizontal and vertical planes

30. Searching with GSM196 + SA198 Antenna A Single search officer can quickly identify source of a signal. The antenna projects an area of sensitivity very much like a torch beam Check readings on the 196 as the antenna is moved. Only really useful for tracing ‘calls’ Lower Level Upper Level Set 196 to ‘S’ mode and put outside each cell suspected of sending GSM text messages. The one with a flashing blue ‘N’ LED will be the cell. For 3G text messages –only the ‘3’ LED will be flashing When walking the landings, the beam is approximately the width of one cell at the window end of the cell. Check whether signal is coming from the lower or upper levels

31. Conclusion  Install CPD3000 system and deploy detectors in wings / cell blocks  Capture ‘intelligence’ on how phones are being used ( call or text) when (time) and where.  Move detectors to hot spots to improve location accuracy.  Search teams to be deployed to active areas with handheld detectors to pinpoint cells if alarms are calls.  Deploy GSM196 units in HO or S modes to monitor suspect cells for text alarms  Continue to monitor area after seizures to see how quick replacements are being supplied.  The phone problem may not just confined to the prison wings

32. The latest security threat : the GSM audio bug  Contains a GSM phone which can be accessed from anywhere. Simply add a Pay as you Go SIM card to activate.  Placed in security offices, operations rooms etc by cleaners – takes only 10 seconds  Allows third parties ( criminals) to listen in on operational planning meetings. Now drug dealers will know when and where to make next shipment to the prison.  Solution Deploy additional detectors in security related areas

33. Mobile CPD3000 system For small prisons where there is insufficient justification to install a system – PDA can supply a complete system in a ruggedized case. The detectors can be deployed and the hub can be ‘hidden’ in a suitable roof space. Data is collected onto a memory stick to be analysed when the system is collected by the regional search personnel. All equipment including hub powered by internal batteries for up to 4 days
