Will GPS Signal Jammers Block Cell Phone Signals?
Do GPS jammers block cell phone signals? In fact, not all GPS jammers block cell phone signals.
At first, the car GPS jammer was a cable installed at the position of the car's cigarette lighter, which could shield the GPS signal through the power supply after ignition. It later evolved into a 1 antenna GPS shield. In addition to being able to power the car, it also has a lithium-ion battery. It can also operate normally for a certain period of time through its own power storage. Later, a shielding device with two antennas appeared, and the two antennas shielded the GPS frequency band and the GLONASS satellite positioning frequency band respectively.
They are pure GPS signal jammers and will not block cell phone signals. But on this basis, portable GPS jammers with 3, 4, 6, and 8 antennas came into being, which can block GPS, mobile phone and WiFi signals, and have more powerful functions. However, 3 or 4 antennas are relatively rare in the current market. In addition to the pure 2-antenna GPS jammer, 6 and 8-antenna systems have become mainstream products.
GPS jammers are all lightweight and have built-in lithium-ion batteries that can work for hours even in the event of a power outage. You can even wear a signal shielding device with 6 or 8 antennas on your body to shield the interference of external data signals in some hidden places when negotiating.
So when someone decides, everyone should be sincere. Do the comparison work, because that's the only way to better understand and make relevant decisions.
In addition to this portable GPS jammer, there is a larger but more powerful class of desktop GPS jammers with 8 or 9 antennas for full coverage of GPS and cell phone signals. It has no lithium-ion battery and can only run on electricity. This type of setup also has adjustable buttons that only block GPS signals or cell phone signals and other wireless channels as needed.
