Why some many people want to use the jammer though the FCC has forbidden the sale or use of the jammer devices?
For instance,some groups or organizations want to use the cell phone jammer. Like in school exam room,the phone blocker can help avoid cheating in the exam.In church,it can provide a solemn atmosphere by against the usage of mobile phone.
More than that,the prison, court and factory,etc where cell phone is not popular all need the help of the phone blocker. And for individual,if someone wanna have a quiet place or be annoyed with the phone call,he may also use a phone jammer.
Moreover, other jammers like gps signal blocker can protect some one from the gps tracking especially for the famous stars or other governors. And the WiFi jammer can help one get away from the threat of indoor tracking.
In a word, where there is a need ,there is a way.
cell phone jammer prevents GPS trackingBut what exactly can these surveillance drones do?
They can even identify if someone is armed at night, and they can track the person's location and send it to law enforcement.
The FAA is committed to addressing all privacy and personal data collection issues, and cellphone jammers prevent GPS location tracking.The U.S. Department of Justice explained that drones can only be used in the United States during war or large-scale terrorist attacks, and that all activities surrounding drone jammers are conducted in the United States.
But we can see that a decision has been made, but Rand Paul is still working to prevent the appointment of a new CIA director, who may support the US government-led strategy.The purpose of drones is to engage in battle on the battlefield.
It is a strike force in the war on terror.
As you know, U.S. senators recently blocked the CIA's new presidential election, most likely John Brennan, using a high-power GPS jammer to shoot down drones from the air.Kentucky Republican Rand Paul used the procedure to postpone the appointment.
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.
