THE ISSUE

• Possession and/or use of wireless communication devices is prohibited by law in Prisons.

• Communication channels are used for synchronizing organized crime activities and possible escape attempts.

• Unauthorized, unmonitored communication channels pose a clear security breach.

COMMON SOLUTIONS

• Focused entry• Detection• Interdiction


FOCUSED ENTRY

• Inmate Re-Entry, Staff, Visitor, and Package Entry Detection by –

• Metal Detectors • X-Ray Machines • Frisk Searches • Perimeter Security


DETECTION TECHNOLOGY

• Cell Phone Sniffing K-9 • Handheld devices• Portable systems• Fixed systems


INTERDICTION TECHNOLOGY

• Jammers - Active• Jammers – Reactive • Managed Access (IMSI Catchers)

BASIC ASSUMPTION

Never Underestimate your opponent !


BYPASSING METHODS

• VHF Cellular Gateway – The inmate uses a VHF radio triggering an external cellular phone.

• WiFi - The inmate uses a Skype phone or other VoIP applications with a WiFi AP located outside the CF

• MSS – Hand held satellite phones• SIM Cloning – The inmate impersonates as a

legitimate “white list” phone


MAIN ISSUE

What do you want to accomplish?


POSSIBLE GOALS

• There are several possible goals when targeting the issue of contraband wireless devices – they are different in the required regulation, technical capabilities and effort.

• Possible Goals –• Detection• Prevention• Location


POSSIBLE GOALS (CONT.)

• Block all unauthorized communication – not interested in confiscating the device and its exact location

• Block + Provide the best estimate for its location

• Passive Activity detection w/ or w/o location


MAIN CONSIDERATION

Never ending story……Multiple networks, carriers and bands.



Prevention


PREVENTION - CLASSIC SOLUTIONS

• High power Jammers –• Disadvantages • Limited usability (static)• Health considerations• RF containment (surrounding infrastructure)• Single point of failure• High cost of ownership


PREVENTION – PROPOSED SOLUTION

• SILVER• A revolutionary architecture which provides

tight blockage and enforcement of wireless access policy with central remote management and additional unique features on top of the prevention infrastructure


PREVENTION- DISTRIBUTED ARCHITECTURE

• Low- medium power Jammers –• Advantages • Better coverage and usability• User/Health friendly• Excellent RF containment (surrounding

infrastructure)• Back up and redundancy• Lowest cost of ownership• Additional functionality made possible


PREVENTION - MANAGED ACCESS• DETECTOR • An IMSI Catcher appliance which prevents illegal

cellular phones usage in a restricted/protected area. • The DETECTOR monitors the cellular phones

activity and upon detecting unknown phone (which is not in the configurable white list) it generates an alarm and block it.



Detection


DETECTION - PASSIVE• ADS• Activity Detection Sensor –• Advantages • Implemented on the return channel of the distributed

jammers• Wide-band• Easy installation no manual calibration is needed• RFF algorithm support• Lowest cost of ownership• Additional functionality made possible



Location


LOCATION IN CELLULAR NETWORKS

• GPS/GLONASS Based (or assisted)• RF “Finger Printing”• BTS Triangulation• “Last room” – via homing device using a “silent

call”/other


IN-JAIL-LOCATION

• Usually no GPS/GLONASS signal• Highly dependent on construction materials• Multipath issues• Last Jail Cell – VERY visible to the inmates


LOCATION – PROPOSED SOLUTION

• HSS SEAL• Combined system comprised of a fixed deployed geo-

location sensors (return channel) with ad-hoc tactical survey team using specifically implemented algorithm for in-building location


LOCATION – POSSIBLE INSTALLATIONS

• Fixed, using pre-installed remote units (return channels of the Jammers)

• Survey – Tactical Team – mobile , fast deployment system (outside or inside the CF premises)


COVERT OPERATION

• Antenna Concealment (in cameras, poles, signs etc.)• Minimal infrastructure “signature” (main operating

center may be operated from a standing vehicle)• Central Operating Center– all of the system’s

products are visible from a single location


POA GEO-LOCATION

• A set, of geo-location sensors, used to Geo-locate any emitter (regardless of the protocol used)

• Wide band detection – covering all relevant wireless devices

• Best suited for indoor Geo-location


CONTROL CENTER

• Unified user interface for controlling all entities in the CF - IMSI Catchers, Jammers ,Geo-location sensors

• Display the location of the sensors, jammers and detected emitters over a map/floor plan.

• Manage multiple deployments• (fixed and mobile) from a single• center.
