Until recently, satellite navigation system outages in populated areas were a rare and sometimes sensational phenomenon that caught everyone's attention on social media and the news. Yet such incidents seem to be becoming the daily norm. With the invasion of the Kremlin region on the night of May 3, the era of "GPS failure" suddenly began (in every sense of the word). The public immediately blamed this on the machinations of "Bandra".

Drivers in central Moscow learn to fool GPS jammers

Then there were problems with car navigation and car-sharing services in the city centre. Russian intelligence quickly deployed "phone jammer" to jam GPS/GLONASS signals in the area, effectively jamming the guidance systems of any drone that tried to replicate its early May night adventure. Now, if you rely solely on your smartphone's navigation system, you might mistakenly think that a person is somewhere on the outskirts of Moscow.

Philadelphia (CBS) - What is a cell phone jammer? Why don't we all have one?

Dean Liptak, a Florida high school teacher turned professional wrestler, has had administrative and legal troubles recently. Imagine telling that person you forgot your science homework. Not for slapping a teen in desperate need of an attitude adjustment to the mat (although one can only imagine the fortitude it would take to not do it on a daily basis). Instead, he found a less aggressive but more illegal way to stop kids from checking their phones in class.

Liptak brings to schools cell phone jammer, radio frequency transmitters designed to block, jam or otherwise interfere with authorized radio communications. The device blocks cell phone signals and prevents teens from using their phones.

Washington - After considering how combat might be conducted in many different environments, the U.S. Army is changing its approach to long-range electronic warfare, signals intelligence and cyber systems.

The U.S. Army will customize long-range jammer device for the European and Indo-Pacific theater

The Land Layer System-Brigade and Above Echelon (TLS-EAB) is intended for use by larger Army formations, including divisions and armies with thousands of troops and extensive firepower. The system is considered a key part of the service's "depth awareness" strategy - the ability to identify, monitor, target and engage adversaries from longer distances with greater precision.

According to a now public DHS assessment, small gps blocker, particularly "personal privacy devices" readily available on the Internet, pose one of the greatest risks to the nation's critical infrastructure.

Homeland Security report details privacy signal jammers risks

According to researchers at the Department of Homeland Security's (DHS) Infrastructure Threat and Risk Analysis Center (HITRAC), these devices, also known as PPDS, are among the three most likely causes of GPS outages. However, of these three scenarios, only the one involving multiple PPDS is considered the most likely to occur and the most likely to cause harm to industrial infrastructure operations.

At least 20 vehicles were targeted by burglars in the Lone Tree neighborhood

The burglars struck at 9:45 p.m. Sunday. Wearing clothing to conceal their identities, they fled in a stolen Kia Sportage that crashed into 20 unlocked cars believed to be easier to access.

The break-ins didn't seem to be widely known among residents, "I don't know what's going on." I have a private garage. So I don't know what's going on."

I've heard that WiFi today is not a completely secure connection and can be hacked. I also heard there's a new camera on the market that I'm afraid will be discovered. Can I protect myself? The Dropcam HD WiFi security camera is a small webcam that works via USB. It offers HD quality video and night vision. It also supports two-way recording and DVR functions. By the way, the webcam is always on and can be accessed through an iPhone, web browser, or Android-based personal device. To prevent this type of private access, many companies now use WiFi jammers to block it.

The wifi blocker uses a private camera to take snapshots

If the Dropcam HD WiFi security camera can find you, it can't stop it from saving the captured data to a connected PC. It should also be noted that live webcam streaming video is streamed and encrypted via cloud services. However, this security camera uses a WiFi connection to connect to a mobile device, such as an iPhone or Android smartphone. The Dropcam HD WiFi security camera costs $149. If you choose to use DVR-style recording, you'll pay $9.95 per month. To prevent your videos from being transmitted to your personal mobile device via WiFi connection, you can use a phone jammer to block Dropcam HD WiFi security cameras and ensure that your privacy is not monitored by others.

Hello, everyone! Can anyone tell me that this Bluetooth SIG can actually use technology to track the location of many devices? Although Broadcom invented the new GNSS chip, the Bluetooth SIG(Special Interest Group) developed this new GNSS profile specifically for the exchange of GPS data. All devices that support Bluetooth 2.0 and later can use this profile to easily share GPS location information with other wave blocker device nearby via a nearby Bluetooth connection. What does it offer us? Let's see.

This jammer will work later to remove the signal and eventually they will disband on their own and later we will also cooperate with Telkom," Deni said at the Garut county government secretariat live, quoted from Antara on Monday.

The weather can also affect the effectiveness of the jammer

1. At present, the power and channel of each base station are different, and the distance from each base station to the prison is also different.
2. It is generally recommended that the gsm jammer is located within a monitoring area of 200 meters or 300 meters without the need for a base station laptop to be installed.
3. If there are base stations, it is necessary to consider the impact of strong signal shielding on high probability base stations.
4. The scale, number of buildings, structure, height, and floor height of each prison vary.
5. The distribution direction, power, terrain and other factors of mobile phone base stations around each prison are different, and the strength of Mobile phone signal signals transmitted by remote base stations are also different

Generally, the transmission power of the Mobile phone jammer is tested within 30W in the test room, so the theoretical shielding range of the Mobile phone jammer in the test room is about 0~20m. But please note that this is the theoretical distance. The actual effect should be combined with local signal strength, especially when there are signal base stations nearby. If there is a signal base station within 200 meters, the shielding effect will be greatly reduced. Walls can also weaken the shielding effect of radio interference devices on laptops. Due to the strong signal near the window, the shielding effect will be weakened. The standard classroom of the school is usually about 75 square meters, and each classroom is equipped with a Mobile phone jammer to achieve better results. It can be placed in the middle of the classroom for maximum protection. Of course, this must be determined in conjunction with the power wiring. It is also common to place cell phone jammer on the podium.
