Hold your breath because you're about to read something that might surprise you. Productivity growth in the United States between 1991 and 2001 was reported to be slower than in the first 20 years after World War II. Do you believe? Yes, it's sad, but it's true.

Many brilliant economists are trying to understand why this is the case, whether it's an aging workforce, the relocation of manufacturing to other countries, or other reasons. But one thing stood out like a sore thumb. This thing is the use of mobile electronic devices.

Yes, this may be the reason for our productivity problems. You see, now we're doing things in a new way that's never been seen before. Surveys show that every American spends 20 minutes a day talking on a cell phone or using a mobile device to communicate in other ways. These numbers are just averages.

You probably know many different people who have more than 20 minutes of talk time on their phones. In addition to long conversations, there are texting, surfing the web, social media, photo sharing, and more. All of these things take a lot of time to complete. So people doing all these things at work just lose their work time productivity and spend less time and more time chatting.

It's hard to say whether cell phones, smartphones, and other mobile communication devices are good or bad. They are all at the same time. But while they can bring some improvements to our work, we have to think about how to use them in the right way.

This Pandora's box won't close once it's opened, and no one can convince us to give up our smartphones. However, if you are an employer, you want your workers to do the necessary things in a timely manner and with the proper quality. There are many ways to convince people to stop wasting time, but they may not have the effect you want.

Modern network technology provides many conveniences in daily life, but it also introduces certain risk factors. How to solve and reduce the frequency of using mobile phones and other electronic devices, modern technology can solve this problem for you. Just install a wireless wifi signal jammer or cell phone jammer in the work area to prevent all interruptions of cell phone calls. In an emergency, your employees can leave crowded areas at any time and make calls anytime, anywhere.

　　August 28, 2004, the United States - McGregor said: During the Iraq War, the Iraqis destroyed GPS navigation data, making it impossible for American cruise missiles, bombers, etc. to locate bombing targets.

　　GPS is a strategic tool. It was later confirmed that the Iraqis had used GPS jammers during the dust storm. Americans rely heavily on airborne GPS and radar surveillance systems, and sadly, all GPS navigation bombs fall off their targets.

　　A GPS jammer is a device that jams the GPS signal and can completely block the Global Positioning System. Such jammers are not surprising in real life. It can block GPS positioning and make it disappear within an area (usually 5-20 meters).

　　GPS is just a very important function in a mobile phone. This makes it easier for people to navigate and gets you where you need to go quickly. At the same time, nearby retailers can pass relevant information to us. Someone recently asked if the GPS is being tracked when the phone is turned off, and whether a portable mini GPS jammer can effectively block the location.

　　Today, mobile phones are no longer the high-quality luxury goods that they once were, and people can buy them easily and cheaply. However, using your phone regardless of the situation can have negative consequences. For example, the noise created by using a cell phone to manage books can affect readers. Using mobile phones in the classroom not only affects learning, but also disrupts educational discipline. Even on the crosswalk, many people are looking at their phones. This is very dangerous. To stop this uncivilized and dangerous behavior, you need to use a cell phone jammer.

　　Mobile phones have brought us comfort and convenience, but they have also brought us many problems. Putting down the phone seems easy. Indeed, how many people can do it. Using mobile phones for a long time can lead to myopia or even deep myopia, which can seriously damage the glasses. At the same time, in addition to playing less and not making calls, you also need to know some methods to prevent mobile phone use.

　　Many cell phone jammers will not only interfere with cell phone signals such as GSM 3G 4G, but also GPS signal jammers, which can set the jamming frequency band to strong GPS WiFi UHFVHF signals. Radio waves are emitted, and this part of the frequency band coincides with the frequency band emitted by the jammer, making it ineffective.

　　We know that all our mobile phones are equipped with GPS navigation and positioning systems. If you use various applets or software on your phone, you will be asked to access your location to get your location. Unfortunately, many thieves and criminals place small GPS tracking devices in our cars and vehicles to monitor us in real time and allow them to carry out illegal activities such as car theft. .

　　Importantly, cell phone jammer are not only powerful, they are also inexpensive, have tunable jamming bands, and are versatile. Some specialized fields, such as military aviation, use advanced technology to reduce the effect of cell phone jammers on GPS navigation by using special antennas that only receive signals in certain directions.

　　GPS is also known as Global Positioning System. We are very familiar with GPS signals in our lives. Our cars, cell phones, and even some smartwatches have GPS positioning and navigation systems. GPS plays an important role, especially in some military fields.

　　Technological developments have played an important role in the further expansion of GPS technology, which is also very important for military applications. In modern electronic warfare, GPS signals are closely related to the life and death of the army and even the army. Advanced GPS satellite positioning systems and GPS signal jammers are the equivalents of powerful umbrellas and sharp arrows.

　　GPS signal system is also very important in our real life, such as GPS tracking, car GPS navigation, and many GPS software for mobile phones, especially GPS locators. Some detectives and criminals use GPS to track and identify us in real-time. Information seeking an improper advantage. With GPS Jammer, you can completely block your location information in real-time to protect your privacy and personal rights.

　　Cell phone jammers are the best products for blocking signals. Installing a signal jammer is easy. A handy jammer is an electronic device that blocks signal transmission between a cell phone and a base station. When using the same frequency as a cell phone, cell phone jammer can strongly interfere with communications between callers and receivers. Effectively block signal transmission from UMTS, 3G, CDMA, GSM, PHS.

　　Mobile phones use different frequency bands in different countries. The 1900 MHz band is the dominant frequency band in Germany, especially in urban areas. 850 MHz for local backup. In the US, the 850MHz and 1900MHz bands are used depending on the region. Europeans use the GSM900 and 1800 bands as the standard. These bands are also used in the Middle East, Africa, Asia and Oceania. In Russia and some other countries, local operators have licenses for the 450MHz frequency to provide CDMA coverage.

　　Using different frequencies makes it difficult to place jammers on all frequencies. Previously, you had to manually adjust the signal range for interference.

　　However, all jammers on the market today have corresponding antennas. Just buy the corresponding nuisance model and install the corresponding nuisance antenna to easily interfere.

　　U.S. Air Forces, warships, and allied air forces are organized into large "air strike groups" to minimize U.S. regional GPS signals near closed training areas. Fight against competitors. Advanced GPS jamming techniques are likely to be used to prepare for the worst combat without GPS support, but this has serious implications for many domestic civil aviation flights.

　　Military experts say the United States is training a very large army in Northeast Asia. Military equipment is very advanced, surpassing the technological level of other countries. Meanwhile, the largest red flag movement in history took place in the United States and lasted a month.

　　Many important facilities in our lives require GPS satellite systems to determine their orientation. A GPS outage can cause serious damage and irreparable accidents. GPS satellite positioning signals and navigation technology should be used in all countries and in all industries. When using GPS jammers, be sure to pay attention to the area of ​​application and do not use them for criminal purposes.

Before using cell phones, please post a warning at the entrance, be careful not to use cell phones inside the church, and install cell phone jammers inside. You can call 911 from certain locations if you wish.

　　A GPS jammer or blocker intentionally transmits on the same radio frequency as your phone to interfere with the communication between your phone and the cell tower, effectively keeping your phone within range of the GPS jammers. This. Prevent cell phone interference as it cannot be used. If you need to block internet connections around you, there is one thing you need to know. You can't block wired internet unless you cut the cable. However, other types of internet, such as wireless networks supported by WiFi and Bluetooth connections, are easily blocked.

　　Use a cell phone jammer or signal jammer to prevent the machine from receiving signals, achieve zero noise effect, and better rest and sleep at noon and at night.

　　Why install cell phone GPS jammers? Some students use their cell phones to text each other during exams, check their writing online, and put up shields to prevent students from cheating on their phones. Many students lie in bed when they are late for get out of class or study. There is a lot of bad information on the Internet, which is not conducive to the growth and learning of students. Some students text and phone appointments late at night before going to bed, affecting the next day.

　　GPS jammers are often identified as interference that may occur due to equipment defects or other unforeseen events. Interference-prone devices are subject to various regulations. Jamming occurs when an operator transmits on a busy frequency without first checking that it is busy or cannot hear the station using that frequency.

　　Mobile phones have become an integral part of modern life. There are more mobile phones than ever before, and this number is growing every day with the introduction of new models and types from time to time. It is estimated that there are 7.22 billion mobile phones and 7.19 billion people worldwide. Such a large number of cell phones and their prevalence means that there are a lot of unnecessary cell phones. There are several ways to handle these unwanted calls. One of the most common ways is to keep your phone on silent or vibrate. But so far, that's where cell phone jammers come into play. They provide an effective barrier

　　Blocking one caller at a time is cumbersome and time-consuming. However, cell phone jammers can block all incoming calls at the same time. This can be a complicated process for many people, but it's very simple. Cell phone jammers emit signals at the same frequency as cell phone signals. The jammer then sends this signal to the world. If successful, the phone will no longer receive a signal at the specific location.

　　There are several reasons why people choose portable jammers. For example, business owners can block employees' cell phone signals to avoid interruptions or interruptions to work during important meetings. Jammers can also prevent your phone from sending outbound messages. Humans can use jammers as a security measure to prevent sensitive information from being leaked. It is also used for stop signals to prevent terrorist attacks. Another reason I like the jammer is that it's not a "phone off" message, it's a "service interruption." This means that the caller cannot reach the phone owner.

　　Cell phones transmit their signals to cell towers near their location. Cell towers share the workload by focusing on specific areas. During your trip, your phone will send a signal to every tower along the way. The jammer sends radio frequencies to the same tower and covers the phone signal. The signal from the cell phone collided with the signal from the interfering device, cutting off the communication between the cell tower and the cell phone.

　　Some of the world's most advanced law enforcement agencies use cell phone jammer, making them reliable and convenient. They have been used successfully in many counterterrorism operations to disrupt communications between explosives and cell phones. Law enforcement agencies also use them to prevent communication between criminals. Cell phone jammers have become an important tool in government offices, assembly points, hospitals, libraries, schools and theaters where silence is also required.

The launch of communications satellites, the widespread use of radio waves, and the resulting technologies increase the opportunities and effects of interference. The rise of GPS in the 1970s and the miniaturization of GPS receivers in the 1980s may have been catalysts for the development of new jammers. Applying GPS guidance to munitions enables the United States to develop steerable smart weapons. These weapons are more precise, resulting in greater efficiency and reduced collateral damage in military operations.

During the first Gulf War, many countries recognized the importance of this and the versatility of GPS in modern warfare (besides its utility in smart weapons), and in later years, GPS military signal jammer potential is becoming more and more marketable. America's traditional adversaries openly market high-power military jammers at various defense exhibitions. During the Second Gulf War, Iraqi forces placed Russian-sourced jamming devices on or near buildings on important strategic targets. These jammers are designed to confuse cruise missile guidance systems such as Boeing's JDAM (Joint Direct Attack Munition) and Raytheon's BGM-109 Tomahawk Land Attack Cruise Missile and Enhanced Paveway Missile. There is varying information on the effectiveness of Iraqi interference. British and U.S. forces believe the jammers proved ineffective. In the short term, however, it prompted the coalition to target the jammer with force and rely more on its laser-guidance capabilities. More investment in anti-spoofing and anti-jamming in the long run capabilities in the JDAM suite (even in 2011, there was speculation that North Korea was able to influence South Korea's JDAM arsenal with military jammers), as well as guided weapons specifically developed to locate and target jamming locations.

　　Over time, many mobile devices—especially smartphones—have posed an increasing risk to U.S. drivers, prompting the Governors Highway Safety Association to investigate nearly 350 scientific articles to measure driver distraction. The results may be somewhat shocking. Various things distract the driver and cause breaks. We may be distracted by things like eating and drinking (of course not), talking to passengers, face painting, music, and more, but cell phones and smartphones are by far the worst known distractions.

　　Talking while driving is a known issue and will develop over time. But texting while driving is even worse! Your hands look idle when you're talking in your headset. For your phone or smartphone, you can release it with one hand while looking directly at it. But your attention is diverted. But texting is the devil. Look at your smartphone, not the street, when texting. According to the aforementioned GHSA study, 25% of car crashes (ranging from minor to fatal) are caused by smartphone use while driving, so having GPS jammers in your car is important.

　　If you are a business owner, you can equip your mobile workers (fleet drivers, suppliers, etc.) with smartphones. Why? Because it is practical, modern and necessary. Talking and texting while driving not only puts these drivers and other road users at risk, but it also endangers company property. Many states have banned or planned to use cellphones while driving, but many ignore those bans and continue to create collisions and dangerous situations.

　　Distracted driving is very exciting. It could be from your parents, your boyfriend or girlfriend, or another important call. But stop and think. Is this phone more important than your life or the lives of other people on the street? Maybe not. So, if you want to reduce distracted driving but don't want to take calls, you should install a cell phone jammer in your car. The small storage radius only covers your car and there is no other space, you will feel safe and comfortable on the road.

　　The range varies, but in most cases the person who needs to make a call can get out of the classroom and do so without disturbing others. In between emergencies or presentations, all signals are instantly restored by simply switching off the device. For a simple jammer to disable student phones in small classrooms, you don't need an overly powerful jammer. In tight spaces, you can use cell phone jammer just like a normal cell phone.

　　The Canadian government has launched a 90-day public comment period to license technology to prevent the inappropriate use of mobile phones in restaurants, theaters and concert halls. With the exception of Israel, technologies that interfere with GPS jammers or jam cell phone signals are banned in most countries. Industry Canada wants to make cellphone silencers available to as many listeners as possible, and Industry Canada in Ottawa wants to help the public decide whether they should consider applying for a license for the devices.

　　Canada will decide by the end of the year to change its current licensing policy. This prohibits the use of portable jamming technology by public safety, law enforcement and other government agencies. Public safety is our primary concern as many fire and police departments use the same frequencies as the public telephone system.

　　Social pressure can eventually slow down cell phone use in inappropriate places. Over time, society will decide what behavior is acceptable. The Radio Canada Advisory Committee (RABC), an Ottawa-based trade group for equipment manufacturers and service providers, said using the technology would have "legal implications" for Industry Canada and manufacturers of cellphone silencers. The RABC's Mobile and Personal Communications Committee said in part in a position paper published in November: "A denial of service (especially emergency services) can have legal implications for service providers.

　　Using a cell phone jammer is "a simple matter". Entrepreneurs must be able to do what they want on their premises. I didn't notice any interference unless their signal went into a common area.

　　Properly placed GPS jammers or gsm signal jammer could interfere with signals across the United States, U.S. Department of Homeland Security officials said at a GPS conference in Nashville, Tennessee.

　　A 1-watt GPS jammer can cover a medium-sized city, and a tenth of a watt can travel 9.4 miles, or a 1-watt jammer. 29.8. miles, watt jammer is 94.2 miles. Inside GNSS is a magazine about GPS and other satellite navigation systems operated by China, the European Union and Russia. This is called a global navigation satellite system. Consumer GPS jammers in these power levels can be purchased over the internet from most Chinese manufacturers starting at $40.
