Some priests use jammers at sermons and funerals

[Perfect Jammer]

Is it really possible to steal a boat with a GPS jammer?

"How to Sail a Ship" will be one of the presentations at a U.S. Department of Transportation symposium on December 3. The event will feature speakers from Maersk, the U.S. Coast Guard, MARAD, and the department's research and technology division.

Jammers, jamming signals, and spoofing (sending false signals to make receivers report that they are in the wrong position) have become an increasing concern for operators over the past five years. A study by Germany's DLR Institute found that GPS frequencies were interfered with during a year-long journey between Europe and the Far East, as well as at every stage of the return journey. In 2019, the U.S. Coast Guard listed GPS signal interference as an "urgent concern" for the International Maritime Organization.

While GPS interference is a concern for ship operators, it is also a problem at all stages of the maritime supply chain, including rail, road and cargo handling ports. When hijacking trucks, stealing cargo, and loading stolen vehicles into containers, criminals often use GPS interference to disable tracking devices. Port operations across the country are often disrupted when truckers want to beat fleet tracking systems and introduce gps blockers in port areas. Unfortunately, a lack of monitoring systems and business issues mean that reports of these incidents are hard to detect and often not made public.

Interference to the onboard receiver is more pronounced. The onboard Automatic Identification system (AIS) broadcasts GPS location information almost continuously. AIS signals are picked up by onshore and satellite sensors, and much of the information is publicly available or easily accessible.

In 2017, maritime leaders reported patterns of phone interference detected in the Black Sea by the Resilient Navigation and Timing Foundation. Hundreds of ships reported their position in the middle of the Russian airfield. A subsequent study by the nonprofit C4ADS found that nearly 3,000 ships were affected in two years.

Ships in Chinese ports often spot GPS receivers that show locations hundreds of meters from the shoreline and around government buildings. This deception technique seems to have appeared on the black market and can be seen elsewhere as well. The nonprofit Skytruth, which documents the wide distribution of ships around the world, reported that they had left Northern California and were circling.

So, is it really possible to steal a boat by tricking a GPS signal with a jammer?

4 places you must need to move jammers

In the United States, the Federal Communications Commission says that "the use of 'cell phone jammer' or similar devices designed or authorized for radio communications (signal jammers, GPS jammers, text jacks, etc.) is interference in violation of federal law." Gee, even though it's illegal to sell jammers in the U.S., it's easy to buy jammers overseas (as long as they don't get taken away by retailers). The only legal purchasers of such equipment are civil servants.

Liptuck walked away (five days without pay); A Florida man has been fined $48,000 for being subjected to human interference in his car for months on end. At least one pastor has used jammers during sermons and even funerals, reportedly with police approval.

Of course, the driver, the priest, and the professor may have used questionable judgment, as the jammer not only blocked their limited location, but also blocked them. But they all had the best of intentions, and perhaps Liptak had the best of reasons: to gain some notoriety, we call our future a worry.

In the past, classroom interruptions were limited to looking out the window, passing folded notes or secretly reading comic books. Now, students can perform all of these actions and more than 1,000 actions on a single screen. How can teachers at any level compete with YouTube, Snapchat, Trivia Crack or even PornHub?

Society should condemn Liptak, but should study ways to improve the abilities of teachers who need such help. The FCC and Congress should create an exception to the Communications Act of 1934, on which many cell phone jammer restrictions are based. Companies should be allowed to find new ways to make easily controllable jamming devices.

Because, let's face it, using limited range wisely in many places, narrowing down the jammer would be a brilliant idea:

Theatre

Over the years, I have tried to call the cinema many times, but the number is always wrong. That is, in the middle of the movie, not only do people's phones ring, but the idiot in question picks them up and continues a normal conversation as if everything is fine and there is no reason to commit a reasonable murder.

Concertgoers, Broadway aficionados, movie fans, etc., don't have to worry about such rude behavior if a GPS jammer used by a theater is triggered within a second when the lights are low.

Dining room

workplace

There is no doubt that in most offices, email and the Internet are an absolute necessity. But what about the phone? According to a survey conducted by Pew Research, only 24 percent of adults have a full - or part-time job and say a cell phone or smartphone is "very important" to getting work done. In other studies, 50% of bosses believe that mobile phones are bad for workplace productivity.

At home

Parents can try whatever parental controls and monitoring software they like, but once a child (or even a spouse or grandparent) has gained smartphone freedom through data, good luck and hope to talk to them while having dinner with your family.

However, you should choose to use a home battery wifi jammers whenever you need or need it.
