Frequency jammers are sometimes common

The drone gun has the appearance of a bazooka; it’s a shoulder-mounted cannon weighing in at 13 pounds, but instead of firing any projectiles it acts as a jammer. With an effective range of 1.25 miles, the drone gun can halt communications between a drone and its pilot, grounding it almost instantly: All one has to do is aim and fire.

Good jammer 2G 3G 4G mobile phone, WIFI, GPS, invisible helmet radio systems and bone conduction. It does not clog the target signal, there is no damage to the target and other electronic products. In short, it prohibits previously defined for a given signal frequency bands: CDMA 869-894MHzGSM, GSM 925-960MHz, DCS 1805-1880MHz 1900-1990MHz, 3G 2010-2025 2110-2145MHz, 4G 2300-2380 2555-2655MHz and and so on. Turn off the power supply, signal interference / blocking signal will stop working, the entire area of ​​the target phone can immediately resume work.

The frequency 4G jammer is a small box, barely the size of a pack of cigarettes, to alter the functioning of electronic keys of vehicles.The perpetrators are therefore located close to their victim. They wait for the latter to lock its doors, or at least think so … Because the housing prevents the closing signal to be taken into account.

So, what is the principle of the barrier used in the college entrance examination? In fact, which equates to time your phone to send and receive information, GPS jammer like a super horn super, the output of ‘noise signal’ too big for your phone can not hear, ‘mouth’ but also call jammers. To put it simply, the work of the shield is far from blocking the signal from the cell phone, but blocking the signal. Equivalent to the use of electromagnetic signals useful in a large number of undesirable signals.

The IJS can operate remotely using ON / OFF switching. If the cell phone jammer components are in buildings or areas away from the control unit, activation of the remote control can operate the cellular jammer remotely.Other options can be used to deploy mobile phone jamming equipment in many buildings or areas. These cellular scrambling units may at any time prohibit access to a large number of cell phones within a group of separate buildings or complex corridors, conference rooms, many small offices and private rooms.
