Mobile phone signal jammer application scope

The interference of the worldwide, countries manufacturer of mobile phone signal shielding device on the market a lot, but very few detailed introduction, so let’s let the jammer – buy professional manufacturer of mobile phone signal jammer in detail the scope of use for us.

Mobile phone signal jammer is also called: blockers, mobile phone shielding device, signal shielding device, mobile phone signal shielding device, mobile phone signal blocking device, mobile phone isolator, mobile phone cutter, mobile communication signal shielding device, mobile phone signal shielding device, cell phone jammer, signal jammer, cell phone block, signal blocking device, mobile phone signal isolator, signal isolator, mobile signal cutter, radio signal shielding device.

For the upstream and downstream channels of the mobile phone system, it USES the technology of frequency doubling, frequency division and frequency hopping filtering to analyze the required shielding frequency. According to blockers power to customize the size of a spherical screen space, automatic forming shielding the magnetic field in the specified scope, make mobile phones (including PHS, PHS GSM, DCS, PCS, CDMA, 3G, 4G, 4G LTE) in the space of mobile phone failure. When the signal jammer is in working state, it can make the mobile phone transceiver function within the specified range fail, unable to dial out and dial in, so as to achieve the purpose of mandatory prohibition.

Common mobile phone signal jammer use place

It can be used in various places such as examination room, meeting room, gas station, oil depot, church, hospital, court, military center, library, movie theater, etc.

However, in densely populated areas such as schools, it is forbidden to set up radio stations with excessive electromagnetic radiation and to use mobile phone signal shields without permission.

Russia has used signal jammers to stop American drones

U.S. military officials say Russia’s jamming technology has wreaked havoc on U.S. drone operations in Syria. Russia’s latest drone jammer are powerful enough to stop any drone from operating in an effective range.

Last week, that u. s. national broadcast company news report that Russia was cautious about a u. s. retaliatory raid on the Syrian regime, after a toxic gas attack on civilians in duma, near the city of damagos. The attack killed at least 42 people, including many children, and wounded hundreds more. Ť his use of chemical weapons is considered a war crime, by multiple international treaty bans.

Drones use GPS technology to navigate. Breaking the connection between the uav and its controller may be simple enough to point the “Dronekiller” device into the vicinity of the uav and “fire” the radio wave. Waves disrupt signals and cause drone operators to lose control. Larger predators and reaper drones are said to have been unaffected, but smaller drones have been adversely affected.

The U.S. military has refused to confirm whether any of its drones have crashed because Russian jammers cited operational security.

Russia denies using the technology.

Yevgeny Serebrennikov, deputy chairman of the Russian defense and security council, was quoted as denying that the country’s forces had used drone interceptor technology.

“This is more misinformation from the us media, which has been happening a lot lately. Russia has insisted that its actions, including in Syria, only in accordance with the international treaty, this action actually could not have happened, “he said.

Are military drones protected against signal interference?

Although American drones equipped with anti-jamming technology, but NBC quoted U.S. officials as saying that the destruction of the Russian technology “is very complex, even for some encrypted signal and the anti-jamming receiver is effective.”
