mardi 7 juillet 2020 05:04:09
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. The difference between these two types of GSM jammers is that the portable 3G jammers are operating in radius up to 15 meters, while the jamming radius of desktop 3G GSM CDMA jammers can be up to 200 meters.
