mobile phone signal jammer and Drone jammer
-
A mobile phone signal jammer is a device that blocks reception between cell towers and mobile phones. Developed for use by the military and law enforcement, these devices were originally created to combat threats like cell phone-triggered explosives and hostage situations.
These days technology of cell phone tower triangulation is quickly spreading across mobile gadgets and tracking devices. This technology allows any tracking device to use three cell phone towers located closest to you to calculate your coordinates at the crossing of their working ranges. So law enforcement agencies can use this technology to find out where you are even if you have no GPS module in your smartphone or if they have not placed GPS tracking device under your car.
With the development of GPS satellite positioning technology, in order to protect their whereabouts, the jammer also emerged, and people bought jammers to avoid being tracked.The most popular one is the mini jammer because of its portable features. If you need to go out with a jamming device,they are your best choice. There are a various portable signal blockers here, such as portable cell phone jammers,handheld gps jammers,portable WiFi blockers.
Here portable blocker has the ability to interfere with multiple signals, with multiple antennas for you to choose from, and you can choose to interfere with the corresponding signal frequency band based on your requirements. In terms of quality, absolutely reliable, and affordable, you can now buy a jammer to fix your troubles if you're worried about the noise of your cell phone and your GPS tracking.
As the drone industry is taking off, some individuals and groups have started using drones for malicious purposes around the globe. Many companies are watching the trend and are trying to get into the counter drone industry. They have introduced all sorts of drone guns, anti-UAS shotgun shells, attack birds, net cannons, lasers, missiles, radio signal jammers, radio spoofers, etc.
More and more people are being threatened by drones. UAVs carry explosives, chemical weapons, biological weapons, etc, and attack military bases. In the face of such threats, buy a powerful drone killer shield may be the best measureto defeating remote control aircraft attacks in the future.
Drone jammer is designed to disrupt a drone by blasting electromagnetic noise at radio frequencies that drones operate and transmit video at, and at a power level high enough to drown out any effective communication between the drone and its pilot. Generally, this is either 2.4Ghz or 5.8Ghz (“RF-jamming”), which are “non-assigned” public frequencies meaning that drone jammers will not interfere with manned aircraft, cell phones, public broadcasts, or other dedicated radio bands. In addition to RF-jamming, where legal for the customer (which depending on the jurisdiction, may include military, law enforcement, first responders and private users), GPS jamming may also be utilized, as a large number of drones rely on GPS either to balance against wind, or to go between pre-determined way-points.
