There are some differences in principles and functions between GPS signal jammers and cell phone signal jammers.
Working principle: The GPS signal blocker mainly interferes with the positioning function of the GPS receiver by emitting wireless signals of specific frequencies. They emit interference signals that prevent receivers from receiving positioning signals from satellites. The cell phone signal jammer blocks or interferes with the communication signal between the mobile phone and the base station by emitting wireless signals or electromagnetic waves, making the mobile phone unable to connect to the network or make calls.
Target signal: The GPS signal jammer mainly blocks the Global Positioning System (GPS) signal and interferes with the positioning function of the GPS receiver. Mobile phone signal jammers mainly block mobile phone communication signals, including GSM, CDMA, 3G, 4G, 5G and other mobile communication standards.
Application fields: GPS signal jammers are mainly used in specific fields, such as military applications, legal enforcement activities, etc. They are used in specific circumstances to interfere with the enemy's GPS positioning function or prevent the target from being located. Cell phone signal jammers may be used to limit or prevent the use of mobile phone signals in certain situations, such as in movie theaters, conference venues, prisons and other places where communication needs to be restricted.
It needs to be clear that the unauthorized use, sale or manufacture of GPS signal jammers and mobile phone signal jammers is illegal and may lead to serious consequences and legal liability. In many countries, use of these devices requires specific authorization and is subject to legal restrictions and regulations.
