What is GSM

GSM, also known as Global System for Mobile Communications, is considered the second generation (2G) mobile phone system, and it is by far the most successful global mobile communication system. The GSM system is mainly composed of a mobile station (MS), a mobile network subsystem (NSS), a base station subsystem (BSS), and an operation and maintenance center (OMC).

GSM Jammers

GSM 3G 4G Signal Jammers for sale Jamming Frequencies

GSM is the most common frequency range used to interfere mobile phone networks and mobile communications. It includes four main frequency bands (850MHz, 900MHz, 1800MHz, 1900MHz) and uses many smaller standards (like UMTS, CDMA2000, Nextel, TDMA, AMPS, W-CDMA PCS, etc.) in different countries around the world. The main advantage of GSM is that users can choose the quality and low cost of SMS from more voice choices.

The current GSM blocker is not only used for GSM interference, but also shields GPS and WiFi signals. With advances in technology, people can track your location not only through GPS satellites, but also by tracking cell towers. There is a modern assistive GPS technology. It combines GPS satellite tracking and mobile phone tower position triangulation to quickly and accurately find your specific location, so that you are constantly being monitored. It is embedded in many new microchips in tracking devices and phones.In order to fight this complicated device, we need the jammer to interfere with GSM and GPS signals.

Most importantly, these GSM jammers are affordable and portable, they not only can interfere with gsm signals, but also block 3G 4G WIFI GPS signals, protecting your privacy and location at all times.

We need GSM Blocker

Although many national carriers have proposed shutting down GSM spectrum, it is still used in many countries and covers a wider range of areas, such as GSM anti-theft systems, rather than just communications.

Even 3G, 4G signals popularization, 5G signal will be overwritten, but still the GSM is crucial to the mobile communication signal frequency, and the cause for mobile phones harassment and noise is based on GSM network, therefore the GSM jamming device you may need to be used to solve these problems.

GSM network to be replaced by other type of cell phone signals in many countries, the network speed is faster, more aspects of the signal type is used, also caused many problems, the wireless network of monitoring to the family, the infringement of privacy in your life.
