7 CHAPTER 2 BACKGROUND 2.1 Cellular Phone Detectors Available Today To get a good grasp on what is available todaylet’s take a close look at some off the shelf cellular phone detectors. Most detectors are manufactured with the intent that the cellular phone is stationary and powered on. They generally have the same features and it is questionable whether or not they actually detect a cellular phone. The two most popular cellular phone detectors available on the market today are produced by Berkeley Varitronics Systems and Mobile Security Products. These companies produce the wolfhound cell phonedetector and Cellbuster respectively. 2.1.1 Berkeley Varitronics Systems Wolfhound Cellphone Detector Berkeley Varitronics Systems wolfhound cell phone detector will detect PCS, CDMA, GSM, and cellular bands using RF signatures. It also has the capability to directionally find or locate cellular phones that are nearby. The wolfhound, according to

Wolfhound cell phone detector features [2]: 40 to 50 foot radius of coverage -60 dBm sensitivity Audible alert Vibrating alert One-handed operation Continually scans for cellular phone uplink activity Integrated laser-assisted directional antenna Estimated battery runtime of 18 hours The Wolfhound on paper seems to be a great way to detect cellular phones, but may just randomly detect cellular phone communications in the area and not necessarily the phone or device that set it off. A couple of quotes from their advertisement imply this: "It took only two hours to find five cell phones that were either in use at the time or hidden in the jail cells on standby mode ready to take calls[2]" and "With only 30 minutes of operation, the device can detect many cell phones and identify the positions which led the team to find 10 mobile phones[2]." These two quotes suggest that their device is picking up transmissions in the area, but it doesn'tshow that they were directly from the phone they found or a phone at all. Small print at the bottom of their advertisement reads, "Standby mode (autonomous registration) varies from base station to base station with phones typically

9 registering between once every few minutes to up to 20 minutes. This time varies greatly based upon carriers, distance from base stations and individual handset manufacturer's standards [2]." This again casts some doubt that their equipment is easy to use and won't just be picking up random cellular transmissions or other devices in the area.Also searching the internet for reviews or feedback about the device produces no results. This uncertainty about whether the detecotr works makes the Wolfhound very similar to the Cellbusters cellular phone detector.
