As a beginning we should mention that it can block any signal from cellular phone around. If you are a businessman you'll know this very well. By having a such jammer you will not need certainly to concern yourself with being threaten on the telephone because no-one will be able to know you. cell phone jammer Every businessman can feel safe while making his latest deals or offers on the telephone, needless to say, if he is using mobile phone jammer. If you block the signal of the cellphones you could have no worries while speaking.
Another benefit is that you will stop the annoying interruptions by phone ringing while making a significant conversation. Imagine that you are in the middle of a good deal and someone's phone is ringing. With the aid of GSM jammer this will not happen. If the telephone was ringing before it absolutely was blocked, once you disable the jammer, you'll receive a voice mail informing you about a missed call.
Something which you will find hard to assume about mobile phone jammers is that you can prevent an enemy attack with them. The reason being all the terrorists are using GSM frequency to communicate with one another and if you block them they'll not be able to do anything. Terrorism is really a major concern for all the biggest companies so having a mobile phone jammer is one good solution to secure your employees and safe a huge selection of lives.
If you are not used using mobile phone jammer maybe it's high time for you yourself to reconsider your choice - the advantages of getting such device are numerous. You'll recognize that when you purchase one jammer. Make your home and office safer, more welcoming to people and last however, not least - quieter.
Cell phone signal jammer in prisonIn the battle to keep criminals from using contraband cellphones in prison, law enforcement may be a bit closer to having technology that could jam phone signals inside correctional facilities without affecting nearby communications.In January, Perfectjammer said its researchers installed the jamming technology in a utility closet adjacent to a 13-by-eight foot cell on the ground floor of the prison's housing unit, according to the study.
It successfully blocked cellphone transmissions in commercial bands between 700 and 2170 MHz, but did not disrupt commercial transmissions when monitored at 20 feet and 100 feet outside the cell, said the study.The data in the report will be used by the Federal Bureau of Prisons (BOP) and the Department to understand the efficacy of micro-jamming, conduct further evaluation of wifi jammer technology, and develop recommendations for strategic planning.Jammer testing and resultsThe test’s data show that the micro-jammer’s signal disrupted commercial wireless signals inside the prison cell, meaning that if cellphones were operating inside the cell, they would have been rendered inoperable.The microjammer targeted CMRS service indoors in a single medium-security prison cell.
Spectrum measurements of the jammer emissions were performed at two places inside the targeted prison cell and at two nontargeted nearby locations outdoors.
GPS jammer emission measurements were performed at each location with multiple measurement bandwidths and detectors across a frequency range of 300 MHz to 4.34 GHz.At the measurement locations inside the prison cell, measured differences in incident power between when the jammer was on versus off showed that jammer incident power levels were much greater than that of the ambient CMRS power levels.
For the outdoor locations where jamming was not intended, the jammer’s incident power was measurable at 100 feet from the building.
However, outdoors the incident jammer power levels were lower than the ambient CMRS levels.
In February, 2011,there was a conflict in Cairo.
The situation was very difficult, the streets were full of protesters and the police try to stop all the protest actions and ask people to leave the Tahrir Square so that the peaceful atmosphere could be recovered.To stop coordinated activities of protesters the government shot down the mobile connection in the whole city.
In a few hours it was restored but jamming devices for local GSM frequency blocking were used in places of big crowds like on the Tahrir Square and other epicenters of riots in Cairo.
Because of the usage of GSM jammers, the coordination of these groups via cell phones became impossible and the aggravation of the situation in the streets of Cairo was stopped.
Also the usage of cell phone jammers made appliance of radio-controlled explosive devices of radical protesters impossible.
Some explosive devices are activated via the signal of the mobile phone, and GSM jammers prevent the successful appliance of such bombs.A cell phone jammer is a device designed to block any signals that mobile telephone sends and receives.
Again, this is either a lack of will or knowledge.
"Thales's new jammers were tested by the prison administration of two institutions in the Paris region.Mobile phones are officially banned in prison...
But the prison administration seized more than 27,500 units in 2016.
A record - three times more than in 2016 - and "real plague; According to Isabelle Gorce, the head of the prison administration, in February, the mujahedin committee on oversight of the jihadist group said in the hearing of the national assembly.
Christiane Taubira, in writing in January, responded with a written response to the United Nations population and development board's question of "restrictions," "very expensive," which quickly became "obsolete," and in the face of technological advances, such as the transition from 3G to 4G, that would explain the regulation of the Seals.To address these concerns, a group of scramblers was established in 2016 by several industrialist working groups supported by the French defence industry group, Terrestre (GICAT).
Results: the new generation model is now being tested in two institutions in the Paris region, including Fresnes.
Die Nachfrage nach Störsendern ist größer geworden, und viele Länder sind allmählich nachlässig geworden.
Angemessene Verwendung ist das Wichtigste.Die New Yorker Taxi- und Limousinenkommission erwägt Berichten zufolge einen Vorschlag, Handy Störsender an Taxis und Limousinen anzubringen, um zu verhindern, dass Fahrer ihre Telefone verlassen und auf die Straße achten.
Aufgrund der begrenzten Anzahl von Störsendern wird den Passagieren empfohlen, immer vom Rücksitz aus zu telefonieren.
Die Fahrer lehnen dies natürlich ab und sagen, dass Mobiltelefone für ihre Arbeit unerlässlich sind und mit den Kunden in Kontakt bleiben müssen.Was denken Sie?
Angeblich wurden viele Autounfälle von Autofahrern verursacht, die Telefone benutzten, was die Aufmerksamkeit der Menschen auf sich zog.
Obwohl sehr gefährlich, sind viele Fahrer daran gewöhnt, Anrufe während der Fahrt zu beantworten.
Das Internierungslager ergriff Maßnahmen, um das Mobiltelefon strikt in den Überwachungsraum zu verbietenDas Haftzentrum des Bezirks Anhui Laoshan hat eine Reihe von Maßnahmen ergriffen, um den Mobilfunkraum zu sperren Vor kurzem hat das Internierungslager des Bezirks Weishan in der Provinz Anhui die "fünf Verbote" strikt umgesetzt.
Ausgehend von der Verwaltung von Mobiltelefonen haben wir eine Reihe von Maßnahmen ergriffen, um das Phänomen der Zulassung von Mobiltelefonen in den Überwachungsbereich endgültig zu beenden, die Belüftung zu verhindern und die Überwachung des Überwachungsbereichs zu verbessern.
Ebene.handy störsender Die erste besteht darin, einen Handy-Aufbewahrungsschrank einzurichten und ein Warnsignal anzubringen, dass "kein Mobiltelefon im Überwachungsbereich ist".
Das Internierungslager kauft eigens den Handy-Aufbewahrungsschrank am Eingang der Gefängnis-Empfangshalle.
Alle Polizeibeamten, Angestellten, Inspektoren und sonstiges Personal, das den Überwachungsbereich betritt, sind erforderlich, um das Mobiltelefon im Aufbewahrungsraum zu lagern, und es ist verboten, das Mobiltelefon in den Überwachungsbereich zu bringen.
Die Empfangspolizei ist dafür verantwortlich, zu überwachen, ob das Personal im Überwachungsbereich das Mobiltelefon in den Überwachungsbereich bringt, und wenn sie sich weigern, die Ware freizugeben, kann sie die Zustellung der Waren verweigern und die Situation unverzüglich dem Dienstraum des Gefängnisses melden.StörsenderDie zweite besteht darin, im Überwachungsbereich ein Signalschild für Mobiltelefone einzurichten.
