Signal blocker in the toilet

Recently, my colleagues in the unit have found that the problem of toilet access that has plagued everyone for a long time has been solved well. Almost no one will stay in the toilet for a long time and look at their mobile phones. There are a lot of squat pits empty. There is no queuing to go to the toilet.

This was not the case before. If you want to go to the bathroom, you have to wait in line. If you can’t wait, you ran to go to the bathroom. Just because of this, the leader had a headache. He talked about it many times in small meetings. The effect It is not so obvious, and the problem of difficulty in using the toilet has not been fundamentally solved. In order to avoid going to the toilet as much as possible, some colleagues simply solve it at home, drink as little water as possible, and reduce the frequency of going to the toilet.

It’s not that there are fewer squats. The crux of the problem is that now the mobile phone signal is strong. When some people go to the bathroom, they watch or play games with their mobile phones. This squat is for most of the day. It’s a long time, but the people waiting to go to the toilet are different. It is very uncomfortable to hold back.

In order to completely solve this problem, the leader asked everyone to brainstorm. In the end, either lacked operability or was too expensive to be worth doing. There was a person’s idea that attracted the attention of the leaders.

A powerful jammer

This person’s idea is very simple. Install a signal blocker in the toilet. If there is no mobile phone signal or the signal is weak, how can people who go to the toilet squat in the toilet for a long time? The squat will be empty.

So, the leader installed a signal jammer in the toilet just as the person said, and the effect was immediately apparent.

It is much easier to find the key to the problem and catch the bull’s nose.

InfiniDome has secured a $ 1.6 million investment to protect your GPS from hacker attacks

With vehicles becoming increasingly reliant on GPS systems, it seems pretty scary that a simple store-bought GPS jammer could interfere with your next trip on the highway. Fear not, InfiniDome has developed a simple and efficient solution to keep your GPS on track …

InfiniDome, an Israeli startup, aims to protect vehicles connected to GPS from basic nuisance and spoofing attacks. The cyber security firm must smell the financial potential as it just announced the opening of its Pre-Series A round, despite just closing a recently completed $ 1.6 million seed funding round raised by Next Gear Ventures of Israel, Boundary Holding, and Aston Partners of New York.

Pocket Mini GPS Jammer

Redefine GPS protection
Did you know that for just over $ 30 you can jam a GPS broadcast from a vehicle 30 feet away? It’s not just your car, this security system is critical to the safe functioning of drones, autonomous cars, connected fleets and critical infrastructure. To alleviate this fear, InfiniDome has developed a compact, efficient, and inexpensive device to protect GPS-connected systems from various jammers and spoofers. Based on Null-Steering, a spatial signal processing technique that eliminates all interference in wireless communication, the cyber device enables complete protection of all systems connected to GPS while weakening the hacker’s ability to block or interfere with the signal.

Speaking to Geektime, co-founder and CEO, Omer Sharar said that they have implemented the same principles of electronic warfare within the company that were previously strictly limited to military companies. “Instead of using just one antenna, we’re actually using a few. Combined with proprietary electronics and an algorithm, the system can detect which vector is attacking the vehicle and, by combining it with a received pattern, we can weaken the jammer’s signal. “Comparing InfiniDome’s technology with noise-canceling headphones, Sharar says,” If you’re listening to normal headphones, loud noise can easily drown out the music. ” Headphones with active noise canceling functions can reduce outside noise so you can enjoy your music. This is very similar to what our product offers – the hacker’s interference signal is weakened so that the GPS system can still connect to the satellite. ”

The cyber security startup recently launched OtoSphere, which can be easily connected to commercial and private vehicles. This innovative product is perfect for semi-trailers and Brink carrier vehicles, both of which are heavily targeted towards theft and rely on the monitoring of GPS transmitters at all times.

The latest round of financing will enable the company to further expand its global sales and marketing activities. The company employs 11 people across offices in New York and Caesarea. InfiniDome was founded in 2015 by Omer Sharar, Ehud Sharar and Moshe Kaplan.

Not the only “Infini” closures

Investments simply flew everywhere, the company name begins with “Infini”. As an Israeli-American data storage company, Infinidat has secured another round of investments led by existing investors, Goldman Sachs, ION Crossover Partners, TPG Growth, Claridge Israel and company founder Moshe Yanai. Infinidat developed data storage software that is easily adaptable to any purpose to optimize performance for all media types – present and future. The company’s enterprise data storage solution supports the workload while saving power, cooling and space costs. The Unicorn company’s final round of funding came in 2017 when the company received a $ 95 million investment based on an estimated value of $ 1.7 billion.

Cell phone jammers installed outside Sabarimala Tantri’s office

After 8 a.m., many followers were seen protesting and shouting slogans when the police stopped them to check them out on the way to Sabarimala.

Sabarimala: Kerala police installed cell phone blocker near the Sabarimala Temple on Monday to prevent the Tantri and other shrine officials from interacting with the media and to dissuade live images of it.

The move took place when the contingent of the state police deployed around 2,300 workers for the security of the temple ahead of the one-day pilgrimage, which begins at 5 p.m. on Monday and ends at 10 p.m. on Tuesday.

After 8 a.m., many followers were seen protesting and shouting slogans when the police stopped them to check them out on the way to Sabarimala. Private vehicles carrying pilgrims were stopped.

As of late Sunday, a dozen female officers over the age of 50 were stationed in the temple city, who for a long time had only seen police presence during the puja high season.

The state government is taking all necessary precautions to prevent incidents such as the massive protests against the Supreme Court ruling on September 28, which allows the previously banned age group of girls and women to enter the Lord Ayyappa Shrine.

From October 17-22, when the temple was open for the monthly puja, the temple tantri and officials said they would close the shrine if a devotee between the ages of 10 and 50 tried to enter the Sanctum Sanctorum, like it against that was temple tradition.

The Kerala government has announced that it will implement the Supreme Court ruling against the BJP and numerous Hindu groups that have opposed the ruling.

Application of car jammer in border defense and military

Car jammer protects military and VIP convoys from being attacked by remotely controlled improvised explosive devices (RCIED) buried by terrorists in advance, and can effectively prevent terrorists from tracking the convoy via GPS.

It is used for EOD. Before EOD, it is necessary to effectively shield the wireless communication signal around the bomb to prevent terrorists from detonating the bomb through the remote control wireless device during the EOD process and avoid huge casualties.

It is used for the police to interfere with common communication frequencies in the process of rounding up criminals to prevent criminal gangs or police from leaking secrets through wireless devices and making rounds invalid. At the same time, it can also prevent criminals from remotely controlling bombs at key entrances of the building, allowing the police to quickly enter the building for round-up and avoid casualties.

When border defense and military patrols, prevent terrorists from being attacked by remote improvised explosive devices buried along the way.

Used in military protection areas, government buildings and other important places, shielding wireless signals can effectively prevent terrorists from conducting fixed-point blasting through remote-controlled bombs. At the same time, criminals who have been hidden in the military protection zone cannot communicate wirelessly with the outside world and leak secrets.

It uses external AC power supply, can also be powered by a built-in battery, and also supports external battery box power supply or generator power supply, the power supply mode is flexible!

The equipment adopts a modular design, and each component can be directly plugged in and replaced. Among them, five high-power shielding modules, the frequency can be customized and combined at will

The equipment control method is flexible and diverse, which can be directly operated and controlled on the machine, or controlled by an external wire control box.

Benefits of installing shields in dormitory areas and examination rooms

In recent years, due to the widespread popularity of mobile communication tools such as mobile phones, cheating using mobile communication tools such as mobile phones has become a “secret weapon” for some candidates to improve their test scores. These candidates do not seek hard work on weekdays, but want to use them when taking exams. Some illegal means, or organizations and individuals who listen to some illegal test-disclosure vendors, or provide answers for profit, want to use their mobile phones as answer receiving tools or transmission tools to obtain ideal test scores through cheating, which seriously damages The fairness and seriousness of the exam! It is a great harm to most other students who usually study hard and learn from the truth!

In order to strictly discipline the examination room and ensure fairness and justice for each reference person, installing a mobile phone shielding network intelligent management system or a wireless signal jammer device is one of the most effective ways to prevent candidates from cheating through mobile phones and other communication tools.

According to some school administrators, students now carry a lot of mobile phones. According to the observation and understanding of school administrators in recent years, students use mobile phones as normal applications, but most of them use mobile phones to access the Internet and chat. , Playing games, reading novels, chatting about love, and even more often contacting some idle people in society, which has brought great harm to the education of the school and the growth of students! After the students are checked by the school leaders during the late schedule, it is more difficult to be restrained, managed, and discovered by playing with their mobile phones under the covers.

The school generally recommends that the mobile phone signal shielding system be installed in the dormitory area should only be turned on within two hours after the lights are turned off. The purpose is to enable our students to learn to live and develop good and healthy living habits! Go to bed early and get up early, so that you will not be drowsy due to lack of sleep the next day, unable to concentrate on studying and attending classes.

The technical solution for seamless coverage of cell phone signal jammer in the whole prison area

1. Jammer-mart provides the following shielding solutions for a prison:
1. For the shielding of the internal area of ​​the building, the distance between residents (schools) and other public facilities in the area where the building is located should be considered, and the distance and signal strength of the surrounding communication rack base stations should also be referred to, so as not to affect the mobile phone signals in the surrounding public facilities. For normal communication, our company selects MDPB-25W indoor host product for the shielding in the building to carry out the network shielding of the indoor antenna mode.
2. For the requirement of shielding all in the selected area, our company chooses outdoor large-scale electronic jammer device to cover the inward coverage of the wall cloth to ensure the shielding of mobile phone signals in all areas. At the same time, for the blind spots and leakage points that may exist in the room, use MDPB-5E is installed with patch point.

Powerful signal jammer device

Installation Notes:
(1) On behalf of MDPB-25W indoor host, on behalf of indoor antenna line.
(2) No. 1-3 workshops, two MDPB-25W indoor mainframes are used inside, and indoor dedicated distributed antennas are used to realize shielding in the workshops.
(3) The surface price of No. 4-6 workshops is relatively small, just install one MDPB-25W indoor.
(4) The angle of the indoor distributed antenna is adjustable, which can fully guarantee the realization of the shielding effect.
(5) The interior of the factory building, such as the bathroom, is complicated, and a small amount of small shielding MDPB-5E can be used to make up points in a separate room.

How to shield a base station within 800M

As we all know, the base station is to enhance the signal, and the shield is to shield the signal. The two conflicts with each other. This is a headache for many government agencies that need a shield. Today, I will show you how a prison with base stations around is fully shielded through our scheme.

It is well known that the prison cannot have a signal, but there is a base station within 800 meters of the prison. The prison has tried many electronic jammer devices, but the effect is not satisfactory. There are always signals in many places, which brings great risks to the prison. Our technicians personally took the equipment to the site to investigate the signal strength and site conditions.

(1) There are many residents around the prison, especially in the southeast direction. The shielding project cannot affect the normal communication of the surrounding residents. Therefore, the selection of the shielding project and the design plan require precise and accurate shielding, which is difficult to design.
(2) The new prison administration office building near the factory area and the old prison administration office building in the living area belong to the police office area and cannot be shielded in principle
(3) There is a large communication tower at the location of the prison office building, which will inevitably cause strong mobile phone signal strength in the entire supervision area, and the field strength value is much higher than that of Canggu. The design of the shielding project is difficult.
(4) There is also a communication tower about 800 meters northwest, which will superimpose the signal strength of mobile phones in the supervision area.

USS Boxer used electronic interference to take out Iranian drones, Pentagon sources say amphibious assault ship

The USS Boxer deployed electronic measures to dismantle a drone the US says was operated by the Iranian military, according to Pentagon sources familiar with the situation. The Navy says the drone was wrecked on the Strait of Hormuz on Thursday after it approached the ship and repeated warnings went unheeded.

Iran has denied the US claims, stating that all of its drones will be considered – and that the US ship may have accidentally shot down one of its own military drones.

U.S. Department of Defense officials, who were not empowered to speak publicly, said the drone was one of several threats to the boxer as he drove through the narrow waterway near the Iranian coast. It is said that at least one Iranian helicopter and several fast boats drove towards the ship on Thursday morning. The actions prompted the boxer to send a helicopter, which then flew side by side with the Iranian plane to repel him.

The boats eventually followed radio warnings to break contact, but the drone headed for the boxer instead of turning, the sources say. His presence was seen as a potential threat to flight operations aboard the amphibious assault ship, which carries a number of helicopters, as well as Osprey tiltrotor aircraft and a handful of fighter jets.

There were also concerns that the drone could pose a direct threat: in recent months, Iran-backed Houthi rebels have been using drones to drop explosives on targets in both Yemen and Saudi Arabia. According to a Pentagon source, the drone was unarmed in Thursday’s encounter.

The first US statements about the incident with the boxer did not contain any detailed information about the crash of the drone. On Friday, a Pentagon official clarified that the boxer was using electronic jammer measures to turn off the drone. The officer did not provide details in order not to disclose information about the ship’s capabilities.

wireless signal blocker

The news site states that a new Marine Corps anti-drone system was responsible for the Iranian drone crash, although the military did not confirm the report. USNI News notes that the Navy previously announced that the Marines were operating the jamming system on the deck of a US ship. USNI News described the weapon as one of a new series of “non-kinetic systems” that can cause a drone to crash.

President Trump first announced the crash on Thursday afternoon, saying “The drone was destroyed immediately” after closing within about 1,000 meters of the boxer and ignoring the request to resign.

Shortly after Trump’s testimony, Pentagon spokesman Jonathan Hoffman gave further details, saying a drone approached the Navy ship at around 10 a.m. local time while the ship was in international waters and on an “inbound road transit” von Hormuz “sailed. “”

However, on Friday, Trump said the U.S. ship shot down the drone, contradicting Pentagon officials’ report that the boxer was using jamming features. “No doubt no,” Trump said in the Oval Office, according to a White House pool report. He added, “We shot it down.”

When asked if he was concerned about the possibility of a major clash with Iran in the Strait of Hormuz, the pool report quoted Trump as saying, “No, not at all. … We hope they don’t do anything stupid about them. ” When they do that, they pay a price no one has ever paid before. ”

Also on Friday, a senior Trump administration official said the U.S. government had evidence that the boxer destroyed the drone and said more information about the shutdown would come from the Pentagon.

“We have very clear evidence, the Department of Defense issued its statement on the boxer’s actions,” the official told reporters on Friday. “The Iranians don’t have a great story with the truth. We are very confident in the president’s announcement.”

When asked if the Trump administration would take further action against Iran, the official said the US was ready to defend itself.

“It was your drone that approached our ship,” said the officer, adding, “If you keep doing this. If you fly too close to our ships, you will be shot down.”

US military officials say Iranian helicopters and drones often flew near US ships as they crossed the Strait of Hormuz between the Persian Gulf and the Gulf of Oman.

In an incident that began in August 2017, according to these officials, a US ship was harassed by an Iranian drone that flew near the ship during night operations. No shots were fired, but the encounter was classified as “clearly unsafe”.

Terminator-signal jamming gun drone

What is a drone jammer?

The signal jammer is also called a signal blocker. They are devices that block radio communication signals. A pilot on the ground remotely controls an unmanned aerial vehicle (UAV). Therefore, blocking the radio signal makes a UAV useless. The drone will either fall to the ground or land, depending on its programming.

The jammers “had quite a significant impact” on the UN surveillance drones, which were suspended for days after gathering intelligence from the air. US military officials did not say whether the latest interference caused the drone crash, citing operational security.

But sources told NBC that Russia’s sophisticated jamming equipment, which was developed by its military, has proven effective even against some encrypted signals and anti-jamming receivers.

It is introducing DroneGun, a GPS signal blocker that disables drone signals (including GPS and GLONASS positioning) from up to 1.2 miles away. Like most rivals, it doesn’t destroy the target drone, it simply forces the vehicle to land or return to its starting point. Anti-drug teams can not only defuse threats from a safe distance, but they can also locate their pilots.

Most of today’s jammer-mart jammers use a broader jamming signal over a range of frequencies, while BEAM is configured to detect a single specific frequency used by an attacking drone, a solution especially suitable for urban or more populated combat zones.

portable drone signal jammers

US analysts first caught Russian military drones in eastern Ukraine four years ago, after the invasion of Crimea, according to Humphreys. He said the jammers were initially detected as faint signals from space, bouncing off the surface of the earth. The jammers “had quite a significant impact” on United Nations surveillance drones attempting to monitor the area, grounding the fleet for days and halting intelligence gathering from the air.

The drone signal jammer works by directing radio energy into the drone, interrupting the remote control link between the drone and the operator. The jammer operates in common industrial, scientific and medical (ISM) frequency bands. 2.4 GHz, one of the most common frequencies for drone control, is part of the ISM band.

Those mobile phone problems can be solved by jammer

The obsession with mobile phones worries both parents and schools. A middle school found a “new solution”: a mobile phone signal sign is being installed on campus, which can be turned on every night, so that students can’t play with mobile phones at night.

The school intends to block cell phone signals so that students can study, rest and break the idea of ​​play. Mobile phones and games are almost the biggest challenges in education today. A middle school teacher wrote a recently popular mobile phone game, and said that the game has gradually turned mobile phones into “game consoles.” His students also said painfully: “I can’t control myself!”. In order to get students out of the predicament, some unconventional management methods must be used, such as prohibiting the use of mobile phones and playing games. The school needs to do something about this, and shielding the phone signal is much more effective than calling the teacher to inspect the house and adopt strict management measures.

3g jammers

The work of a gsm jammer is very simple, because it affects the frequency of the telephone signal and the frequency of the signal. In recent years, signal interference has been used in various inspection halls, schools, gas stations, courts, libraries, conference centers (halls), theaters, hospitals, government agencies, etc. Even some companies and families are installing them. Interference equipment can be easily purchased on the Internet.

In recent years, with the rapid development of modern communication technology, the use of high-tech fraud methods in examination rooms has emerged one after another, from pagers to mobile phones, to mobile phones, to today’s digital products, and college entrance exams conducted through fraud tools. For cheating tools such as rulers, rubber, spectacle cases, stationery bags, watches, and mineral water bottles, examinations have been carried out in different countries. In order to prevent fraud, the authorities have effectively prevented and stopped fraud in the examination room by using mobile phone locks, metal detectors, radio signal jammers and warning suppression devices.
