Mumbai: Cell phone jammers could soon appear in BMC theaters

“Something must be done to stop cell phone harassment during the game and performances. Jammers will allow audiences to enjoy the show peacefully,” Mhatre said

Pradnya Dongaonkar, a resident of Dadar, has a complaint that will resonate with most theater and cinema goers. “It’s really annoying when a cell phone rings in the middle of a show. Anyone who violates the norms and instructions to ensure the cell phone stays idle or completely shut down should be fined.” While a fine may be a long way off, there could soon be prevention, at least in civil society-owned theaters.

Citing the fact that cell phone interruptions during live performances in lecture halls and theaters have often become a nuisance, the BMC decided at its general meeting to install signal jammer. The proposal was put up for discussion on July 25, 2019 by Shiv Sena company Shital Mhatre. The proposal, which the BMC has accepted for consideration, is now being announced for suggestions and objections.

“Something must be done to stop cell phone harassment during the game and performances. Jammers will allow audiences to enjoy the show peacefully,” Mhatre said.

But not everyone agrees with the idea. Ajit Bhure, a theater personality who heads the Association of Commercial Game Producers, says, “Sometimes people make mistakes, but nobody does it on purpose. Disturbing an entire theater will cause big problems. It will not network people, it will network Artists cut up for four hours. If there’s an emergency during that time, how do people know? ”Bhure suggested instead creating awareness of mobile manners.

However, once a cell phone jammer is installed in a theater, it is no longer a permanent function. “After the BMC has received the necessary permits from the central government, it will continue with its plans. Even with the jammers installed, the facilities will only be made available if the request is made by theaters and producers, associations or organizers. The The application must be made in writing, “says the administration’s letter.

The United States also regulates the use of jammers

Recently the United States bombed Syria

The National Broadcasting Corporation reported that, according to the statement of four US officials, the Russian military has disrupted US military drones that conduct combat missions in Syrian airspace, severely affecting US military operations.

Authorities said that a few weeks ago, after a series of chemical weapons attacks against civilians in the armed opposition zone of East Gutta, the Russians began to interfere with a few small American drones. Officials said the Russian military was concerned the US military would retaliate against the attack and start interfering with the global positioning system used by drones operating in the region.

Republican Senator Ben Sasse reacted on Tuesday to reports of interference with Russia: “Russia wants to undermine our interests all the time.”

He said: “Those who think that Russia is not an enemy are crazy.”

According to Dr. Todd Humphries, director of the Radio Navigation Laboratory at the University of Texas at Austin, blocking or preventing drones from receiving signals from GPS satellites doesn’t have to be complicated.

He said: “Most GPS drone receivers can be very easily disturbed.”

Humphreys, an expert on GPS spoofing and jamming, has warned that it could have a major impact on drones in the United States, causing them to malfunction or even crash. He said that if the drone reports an incorrect position or is lost, “at least it can create confusion for unattended ground operators.”

According to Dr Humphries, four years ago, after the invasion of Crimea, US analysts first discovered in eastern Ukraine that Russian troops were interfering with drones. These GPS jammer “have had a significant impact on unmanned aerial vehicles deployed by the United Nations to carry out surveillance missions in the region.” The crew stopped for several days and were unable to collect information by air.

Pentagon spokesman Eric Paquin of the US Department of Defense will not stand up if such interference leads to drone crashes and has stressed that US military drones are currently operating safely. “The United States military has sufficient countermeasures and protective measures to ensure the safety of our unmanned and manned aircraft, our troops and the tasks they support.”

However, an official confirmed that such interference had an impact on US military operations in Syria.

Jammers make our community safer

In the fight against criminals’ use of banned cellphones in prisons, law enforcement agencies may be closer to a technology that can interfere with phone signals in prison without affecting nearby communications. In January of this year, Justice Department officials and researchers from the U.S. National Telecommunications and Information Administration gathered in federal prisons to test technologies that could disrupt radio services that could interfere with thousands of cell phones that enter prisons each year.

NTIA said the test used prototypes of equipment provided by an undisclosed supplier and successfully blocked commercial cell phone signals in a cell at the Federal Correctional Institution in Cumberland, Maryland, but only 20 feet outside the building wall. Commercial radio waves. Attorney General Beth Williams, Assistant Attorney General, of the Justice Department’s Bureau of Justice, said in a statement on June 15, “These encouraging test results are a step towards addressing the security threat posed by smuggling calls.”

The ability to destroy prisoners’ cell phones has become a major target for the US Department of Justice and other federal agencies. Officials say anything from smuggling cell phones into prisons can create confusion, from controlling gang activity and violent crimes in and out of prison, to spreading child pornography and intimidating witnesses. The Federal Communications Commission passed regulations in March last year to expedite the approval of anti-smuggling systems in prisons. Since they use commercial spectrum, they need an FCC license to operate. Such systems either detect transmissions or use administrative access methods developed from licensed commercial frequencies and authenticate the devices that use them.

According to a study in January, NTIA researchers installed a portable cell phone jammer in the storage room next to the 13 by 8 foot cell on the cell’s first floor. The study claims that it successfully blocked cellphone transmissions in commercial frequency bands between 700 and 2170 MHz, but that it would not interfere with commercial transmissions if monitored at a distance of 20 feet and 100 feet from the cell. However, according to NTIA, further study is needed to determine if the technology poses a potential threat to commercially licensed wireless services outside the prison wall. There are still some obstacles. The agency noted that test results are only for their respective locations and that results can vary widely at other prison facilities.

According to NTIA research, a number of systems are required to fully cover the internment camp – up to 100 cell phone jamming systems. This can lead to serious power problems. Williams said, “The results show that this micro-interference technology can have local effects.” “This is an encouraging signal that brings us closer to a solution that will make our community safer and that will help prevent criminal activity in prisons from continuing.” The Justice Department said the Bureau of Prisons will use the report to get a better strategic view of new technology and continue testing.

GPS Jamming Experiment

Chronos Technology Ltd successfully demonstrated the GPS Jammer Triggered Camera technology during official GPS jamming tests at the Sennybridge Military Jammer Training Area in Wales at the end of August 2015, Lydbrook , Gloucestershire, UK.

JammerCam ™ GPS triggered camera technology Jammer was jointly developed by the Department of Electrical and Electronic Engineering at the University of Bath and Chronos Technology Ltd. This development took place within the framework of a project called “AJR”. Internet of Sensors “Feasibility study competition

The trials allowed JammerCam ™ units to be tested in an outdoor environment with a range of GPS jammer hidden in vehicles passing alone or in convoys, including cars, vans and shipping containers. Jammer-triggered camera sensor technology successfully identified and photographed the vehicle hosted by the jammer in all test cases and at all speeds and powers. Either way, the vehicle was taken at the center of the frame so that only one frame was needed, which significantly reduced the bandwidth needed between the sensor and the web server.

The photo identifying the vehicle with jammer would then be sent over a mobile network to a web server where it is distributed as a hyperlink to target email addresses. The image can then be called up as actionable intelligence within seconds of the camera taking the jammer.

Professor Charles Curry, Managing Director of Chronos, explained: “A proof of concept system was demonstrated during the Sennybridge GPS Jamming trials in 2014 by the University of Bath. We then had to overcome some significant challenges, not the least of which was to make the system fully automatic so that it only took a photo of the vehicle hosting the jammer. We know that even low powered cigarette lighter style jammers emit enough detectable interference to create a power bubble around the vehicle, making it very difficult to determine which vehicle in heavy traffic is hosting the jammer. Our two biggest discoveries were to identify the vehicle in a convoy hosting the jammer, and detect and catch a shipping container with a low-powered jammer inside.

A two-function signal jammer

If you are a teacher who goes to the exam room often, you may want a cell phone signal jammer to make the student more aware. If you are a businessman who wants to keep trade secrets, you might fear that one day you will be tracked because someone may already have a GPS locator installed in your car. Then you can install a GPS signal jammer.

Although some people may not be teachers or businessmen, but only encountered these two problems. More and more people think that it is not easy to keep secrets in modern society because there is too much spyware and spyware. Social software and the Internet have spread enough scandals around the world. There is no secret. It’s another people’s nightmare.

Norway warns pilots of GPS jamming near border with Russia

The Norwegian aviation regulator has warned pilots about jamming satellite navigation signals, including GPS, in Finnmark province, bordering Russia’s Murmansk region, The Barents Observer reported.

The warning was made the day before to the NOTAM operational base (changes in the rules for conducting and ensuring flights and aeronautical information) until January 31, the newspaper notes. SAS, Norwegian and Wideroe planes fly through the specified area, but the pilots of which of the airlines noticed navigation problems is still unclear, the resource writes. The Barents Observer emphasizes that the reason for the NOTAM warning is the complete loss of the navigation signal.

In November 2018, Finland accused Russia of jamming the GPS signal during NATO’s Trident Juncture exercise, held from October 25 to November 7. The GPS malfunction was discussed with Russia at the diplomatic level, and the Finnish Foreign Ministry also summoned Russian ambassador Pavel Kuznetsov on this matter. The Norwegian Ministry of Defense also made similar accusations against the Russian military group in the Arctic. True, it admitted that the navigation disruptions did not lead to any serious consequences.

The press secretary of the Russian President Dmitry Peskov then said that the Kremlin did not know about Russia’s involvement in failures in GPS systems, and forwarded the question about this to the Russian Ministry of Defense.

OSCE announced suppression of signals from its UAV in Donetsk region

OSCE observers appealed to the liaison officer of the Ukrainian security forces, who denied the interference with the UAV of the OSCE mission by the military.

MOSCOW, November 5 – RIA Novosti. OSCE observers reported an incident involving the use of radio interference against an unmanned aerial vehicle (UAV) of the organization during its flight over the territory of the Donetsk region.

The Special Monitoring Mission (SMM) report says the incident took place on 3 November over the village of Chermalyk, 40 kilometers northeast of Mariupol. The OSCE unmanned aerial vehicle was exposed to unknown radio interference, disrupting the normal operation of the device, at 13.01 and 13.19 local time. After the UAV landed, OSCE experts deciphered the received data, which revealed that the aircraft’s GPS signals were being jammed by an drone jammer, according to the SMM report. The report notes that this is the third incident involving SMM drones in Ukraine since October 23.

A test launch of the first UAVs, which are supposed to monitor the ceasefire in eastern Ukraine, took place on 23 October. The OSCE reported that the UAVs will fly in three directions: south of Donetsk and to the Sea of Azov, east – to the Russian-Ukrainian border, and also west – towards the contact line.

In April, the Kiev authorities launched a military operation in eastern Ukraine against residents who were dissatisfied with the February coup. According to the UN, as of October 31, the number of victims of the conflict exceeded 4 thousand people, more than 9 thousand were injured. With the mediation of Russia and the OSCE, the parties agreed on an armistice from September 5. In general, it is respected, but the parties periodically accuse each other of violating it.

Roskomnadzor has declared illegal the suppression of the cellular signal during the exam

Roskomnadzor confirmed that it considers it illegal to use means of jamming cellular communications during school exams. According to the press secretary of the department Vadim Ampelonsky, the State Commission on Radio Frequencies has not yet prepared the procedure for using “jammers” on the Unified State Exam. According to him, Roskomnadzor is obliged to fine schools that jam the signal of mobile phones without this document.

He noted that schools do not have the right to use “jammer” when passing the exam.

The use of cell signal suppression devices without permits is prohibited under current legislation. Including because this can interfere with the cellular signal, the channels of the police, army and special services, – he explained. – And if such illegal use is detected, the territorial bodies of Roskomnadzor interacting with the radio frequency service are obliged to suppress it.

At the same time, Ampelonsky admitted that “in some cases, the use of means of suppressing cellular signals is appropriate.” He confirmed that Roskomnadzor discussed with Rosobrnadzor the issue of protecting exams from cheating using mobile phones and radio headphones.

A draft decision of the State Commission on Radio Frequencies was prepared, which provided for the development of specific parameters of both the suppressors themselves and the signal emitted by them, – said Vadim Ampelonsky. – The proposed solution provided for the possibility of using the suppressors in closed rooms at the direction of the federal executive authority. If we are talking about schools, then it could be Rosobrnadzor. And at the same time, the power level of the suppressor signal should not exceed certain values and should not interfere.

However, the draft decision was never adopted. Ampelonsky expressed hope that the document will be approved by the end of this year.

Recall that devices that suppress the cellular signal have been used during the exam since 2011. Typically, regional government examination boards “recommend” school principals to purchase and use such devices. As Kommersant reported, this year the regional department of Roskomnadzor in the Tver region fined several schools for using jammers.

How to make your own cell phone signal blocker

Cell phone signal jammer is installed in quiet areas, such as schools or universities, but… how exactly does this instrument block cell phones? These locking instruments prevent mobile devices from receiving signals from base stations. While it may sound like a complicated process, making your own phone blocker isn’t that difficult. However, you should know that in many countries (including the United States) they are illegal and subject to large federal fines, in addition to criminal prosecution. Who knows what could interfere …

1. Understand the principles of operation. This cellular signal blocker operates with the GSM800 frequency, since most mobile phones use it to operate. The VCO selected is a sweeping oscillator, which is very effective but can be difficult to build for beginners who do not have good RF testing equipment.
As a noise source you can use a 45MHZ clock oscillator, which is the local oscillator port located on the mini-circuit mixer. There is also an impedance matching network for the local oscillator signal to pass through. It is used to match the impedances of the oscillators and the mixer port.
The RF input (which is the mixer port) connects to the first 800MHz cell antenna, and the RF output is sent to the mini-circuit amplifier. This amplifier increases the output power by 15-16 dbm. Then the amplified signal is sent to the second antenna of the cell phone.

2. Consider how it works. All cell phones using GSM800 always separate the transmitted and received frequencies at 45MHz. So when the mobile phone tries to call, it is blocked by its own signal coming back to you! Isn’t it cool? So when the chatter of the phone irritates you, turn on the blocker so that the criminal hears his own voice on his cell phone. By the way, you can also use this cell phone signal blocker to block any cell-based tracking system that uses your GPS to track and record the movements of your car. And you can probably block improvised explosive devices that are detonated using cell phones. The mixer that is used is designed to work up to 600 MHz, but in this case it works very well. The RF amplifier does its job quite well even though it consumes additional power.

3 Use an old aluminum box as a frame for the jammer and some old UHF connectors from a Motorola cell phone for input and output.

4 Connect the RF connectors to the circuit.

5 Use a nine-volt battery and a voltage regulator to power all components. Place the battery inside and separate it from the rest of the components using foam rubber.
Flip the on / off switch at the top.

6 Screw the input and output antennas (also from an old Motorola cell phone) to the UHF connectors.

7 Your cell phone blocker is ready. Enjoy it!
