GSM signal jammer are devices that block smartphones from sending signals, which can help protect confidentiality during business meetings or negotiations. They are often installed in schools, theaters, commercial facilities, and other places that require prolonged communication.
It is also a means used by criminals to avoid detection after a vehicle is stolen. GPS and GSM signal jamming is a relatively simple way to block wireless communication between devices. They work by generating a radio signal strong enough to cause enough interference to drown out competing signals in the area.
What is the difference between GSM and CDMA?
The Global System for Mobile Communications (GSM) was first deployed in Finland in 1991 and is widely used in more than 200 countries worldwide. AT&T and T-Mobile are GSM wireless networks.
Code division Multiple Access (CDMA) is mainly used in the United States. Verizon uses CDMA technology and is the largest wireless carrier in the United States, but CDMA's market share worldwide is estimated to be less than 20 percent.
GSM and CDMA, both ultimately provide the same service - the quality of service is entirely dependent on the operator, not on whether GSM or CDMA is used.
As 5G(and subsequently 6G) continues to evolve around the world, the differences between GSM and CDMA no longer matter.
What is GSM Tracking?
- GSM tracking allows you to determine the location of the device using the coordinates of the GSM phone network unit to which the SIM card is connected.
- Therefore, knowing the name of the phone and its coordinates, taking into account the distance the phone is allowed to communicate with the phone before connecting with another phone, can roughly know the distance the device is located.
