GSM is the most commonly used frequency range for cell phone networks and mobile communications. It includes four main bands (850 MHz, 900 MHz, 1800 MHz, 1900 MHz) and many smaller standards used in different countries of the world (for example, UMTS, CDMA2000, Nextel, TDMA, AMPS, W-CDMA PCS etc.). Among communication standards 3G must be mentioned separately because it is not only a modern communication frequency but it can also be used with other purposes. Unfortunately, both GSM and 3G frequency bands are used not only to make your life much easier and more interesting, but with bad intentions as well. To jam GSM or 3G frequencies you can choose a portable or a desktop GSM jammer.

We hope that you are aware that cell phone tower triangulation is not the same thing as GPS tracking thus if you need to deal with standard location tracking system you might want to visit the GPS Jammers category.
