Nowadays cell phone is widely used and everyone would keep a phone wherever they go.But there are some situations that we need to be quiet or solemn like court, church,meeting room,school examination room.And sometimes people need to be quiet to learn,to read. That is what cell jammers used for.Besides, some one can eavesdrop your conversations by intercepting your mobile phones signals.And they can also track you through mobile phone tower triangulation which is not the same with the GPS.

 

In the category we provide you the powerful mobile phone jammer that used in the room like church and handheld jammers for someone that need to protect their privacy or confidential informations.And if you want to find a device against GPS tracking,you can visit the GPS jammer category.



If you are an active mobile phone user you probably know that there is a really wide variety of methods major mobile carriers use to promote a new mobile communications standard and advertisers rarely study the technical side of that standard. That's why they always call a new standard of mobile communications a new generation. We in Jammer-buy  want to explain the mobile generations.

We often face pretty unknown mobile generations, 3.5G for example. In a matter of fact even a 3G is a simple slogan that was created for promotion a technology that was simply faster than 2G. In the meantime, 2G has its own divisions, which were created by promoters as new standards were introduced in a second generation. They are 2.5G that emerged when the GPRS technology was presented and 2.75 or 2.9G for promoting EDGE standard. But nevertheless all those 2.5 and 2.9G were the second generation.

So 3G evolved into HSDPA (High-Speed Downlink Packet Access), HSPA, or 3.5G, which is up to five times faster than 3G. Predictably enough, 4G networks are now commonplace, based on technologies called Mobile WiMAX and LTE (Long-Term Evolution). 5G is already in development and expected to become available around 2020.

If you need to use broadband on the move, it's a brilliant solution. Anywhere you can get a good (3.5G or 4G) signal, you can get high-speed broadband.

The drawback is that you're using a cellphone network for your access, so the quality of your connection can vary drastically. If you're working on a train, for example, you can expect to be regularly connected and disconnected as you move in and out of cell coverage—just as a cellphone call gets cut off when you go through tunnels and under bridges. Right now, I seem to be working on the edge of a cell, so the quality of my connection is constantly flickering between 3.5G and 3G and my connection speed is varying from moment to moment. 

But regardless the 3G is rather popular among not only smartphone users. That generation is frequently used in hidden video surveillance, because data transmission speeds allow to stream video in real time and low energy consumption will ensure that a hidden wireless camera will work longer. That's the main reason of the growing popularity of gsm signal blockers.

Android based smartphones display H with a 3G icon in a status bar, when connected to a 3G network. The reason is that Android devices can distinct a common 3G network form its more advanced superstructures. The H letter is diplayed in the status bar when the data transmission speed in the network is 2-15 Mbit/s. We should also mention that 3.5G is actually a brand name for all the superstructures of 3G.

Another interesting fact is that the LTE standard, that is associated with a fourth generation of mobile communications is actually still closer to 3G. LTE failed to meet the ITC's expectations and that's why it is still 3G, but much more advanced. They even use different frequencies, while 3G works with 2000-2100 MHz, LTE uses 875 MHz, though those frequencies may vary depending on the country and the carrier. That LTE standard is used not only for mobile Internet access, but for hidden video surveillance too. Such hidden cameras are still very expensive and rare, but they are the most reliable way for hidden video surveillance. That's why we've made our best to create an LTE  cell phone jammer that is compatible with all the previous mobile generation and standards.

Many people may be in doubt that is there any danger on cell phone jammer to our health Because they play a variety of frequencies, and are these frequencies dangerous for us? Now more and more people are buying mobile phone placement machines and any other blocking devices. From this point of view, in fact, already know the answer, because the masses of the eyes are discerning. We can fully understand them because we know how important it is to protect your privacy, and because most governments are doing their best to spy on everyone, we have no choice but to buy these jammers and try to protect our privacy.

But we have to technically illustrate this point. On health issues, cell phone jammer has passed all the safety and health tests, thanks to this fact, you can rest assured to buy and use. If you remember, the same health problems were worrisome when the phone was first introduced into society. But after testing, the result is the same - no harm.

Also, from the working principle of the jammer, you should remember that the gsm jammers are transmitting the same frequency band as the phone to interfere with the normal work of the phone, that is, the jammers for us are similar to the phone for us. And today, are there any equipments we stay with together longerthan the phone itself ? What kind of equipment is more popular than mobile phones? So, if we are talking about the harm of mobile jammers - they are the same as the phone itself. With Wi-Fi signal blocking the same thing, are they just as a Wi-Fi hotspot, are these hot spots dangerous? Another point you should know that radio signals and light, sound waves and gravity follow the same inverse law, that is, the distance is doubled, the energy is reduced to a quarter. In other words, the signal strength is attenuated with increasing distance. The most interesting fact is that people are concerned that GPS / GLONASS interference devices are harmful, but they do not even know that they are surrounded by the signals of these positioning systems every day.

Then we would like to remind you again here that it is very important to know what type of frequency you want to play. You can find any type of information about the phone blocker and other blocking devices on the Internet and on special websites. One thing is for sure - this technology will not stop developing.

Many people's privacy are now undermined, and hackers or spy organizations (such as the National Security Agency) can easily access our privacy information, and this happens more than one thing. That's why we decided to give you some advice on how to protect your privacy through a variety of jamming devices without hurting others. First of all, we want you to remember that the signal blocker is a weapon that may be bad in the wrong hands, so be careful.

There are many dangerous devices available for tracking, eavesdropping, and can collect many specific data such as login / password, email and people you know - your smartphone. Modern smartphones are dangerous regardless of the manufacturer and the mobile operating system. The main reason is that the device has all of your data. Your personal information, your current coordinates, your friends, private photos and so on.

Hackers are trying to find new ways to snoop on your smartphone. Because the quickest access to large amounts of data is the easiest and cheapest way. The most dangerous thing here is that you do not know what to do to be able to protect your privacy. Hackers are too hard to prevent, no such anti-virus, firewall or encryption method, will be able to protect your data without killing the gadget.

In addition, all of these encryption programs are quite complex, so most people will be confused at all. There are two decent choices that may hide your information. The first is GSM jammers, which will hide you in a very short time, but you will not be able to make or receive calls. The second is to avoid storing private and valuable data on portable gadgets, smartphones, or tablets. Both will cut the functionality of your device, but it will definitely prevent data leakage.

The second thing you should worry about is the wireless network. They are unreliable, hackers use this. Most smartphone users connect free Wi-Fi hot spots in public places, not only online, but also install updates and handle mobile banking information. This is very dangerous, your privacy information is likely to leak because of this.At this time,the WiFi jammer can help you.

Many people unknowingly place private information at risk. They are shared with their smartphones via social networks and transmitted over the Internet with unencrypted protocols. That's why we always tell the reader that the security of their private information is their concern if they do not at least do that nobody can protect it. Protect your information, it's easy, but very important!

Eric, a man in Philadelphia, was tired of chatting on the SEPTA 44 bus talker. According to a Philadelphia reporter, when he did not want to hear the conversation, Eric would open the gsm jammer.

Eric told NBC 10, "A lot of people are very loud, no privacy or anything, and when it gets troubled, that's where I screw the antenna and turn the switch."

Eric claimed that he did not know that blocking the phone signal was illegal and thought it was a "gray area". He said that his impression was that it was illegal to prevent television or radio signals.

But even so, he is not very sorry for his behavior.

"I think I'm putting the law into my hands, frankly, I'm proud of that," he told reporters.

The interference agencies used in this case are illegal, including the possibility of blocking mobile communications in an emergency situation, as they can block other important signals such as police radio and other two-way radios.

But the bigger question is that Eric is not alone in this interfering practice.

Jammers are easy to buy on the site, "Forbes" reported that other people in New Jersey and New York are also using them.
