With the development of technology, many people can not live without mobile phones, but mobile phones can easily leak our personal information and listen to calls. In both business and military, mobile phones can be used as illegal eavesdropping devices, spy mobile phones can steal sensitive information in many important places, and it is extremely hidden. If you're worried about tracking GSM numbers, our GSM jammers are the perfect solution to these problems. It blocks all overwritten calls and protects your privacy. The use of GSM alarm jammers Driven by the Internet, this situation is becoming more and more common, and it is easy to buy gsm jammer. It blocks any alarms that are connected through GSM.
8 Bands JammerWhat is GSM interference?
GSM is the most widely used frequency range in cellular telephone networks and mobile communications. It includes four major bands (850 MHz, 900 MHz, 1800 MHz, 1900 MHz) and many smaller standards used in different countries around the world (e.g. UMTS, CDMA2000, Nextel, TDMA, AMPS, W-CDMA PCS, etc.). .
As the name suggests, GSM jammers can interfere with the airwaves transmitted and received by a cell phone jammer, thus disrupting the phone operator's frequencies and thus blocking communications. GSM jammers or GSM jammers block only the GSM band. Radio communication of the plant and its components is not affected as it passes through the 433 and/or 868Mhz bands. As a result, thieves use GSM jammers to prevent alerts from being sent over the phone.
GSM gps jammer work by simply emitting noise over a frequency band, which prevents the phone from distinguishing that noise from valid data.
How to implement GSM shielding?
Although different cellular systems handle a variety of different signals, all networks use basic radio signals in ways that can easily be interrupted. GSM2 is a system for digital cellular as well as PC-based systems, operating in the 900 MHz and 1800 MHz bands in Asia or Europe and the 1900 MHz bands in the North. America.
Jammer device are capable of successfully broadcasting any type of frequency, effective against CDMA, AMPS, GSM, TDMA, DCS, PCS, Nextel and even iDEN systems. "Old" analog phones as well as today's digital devices are prone to crashes.
GSM anti-jamming
Hide alarm centers and transmitters and avoid seeing them. If there is no alarm device location information, GSM jamming strategy will be difficult to implement.
Establish a dual alarm protocol if the GSM alarm device is interfered with, the program sets the system to automatically switch to a landline telephone (PSTN) or send alarms over the Internet (IP).
Bluetooth is a similar radio wave technology, but it is primarily designed to communicate over short distances of less than 10m or 30ft. In general, you can use it to download photos from your digital camera to your PC, connect a wireless mouse to your laptop, and connect a hands-free headset to your phone so that you can talk and drive safely at the same time, as well as soon. Electronic devices that work in this way have built-in radio antennas (transmitters and receivers), so they can simultaneously send and receive signals wirelessly to other Bluetooth devices. Older gadgets can be converted to support Bluetooth using plug-in adapters (in the form of USB sticks, PCMCIA laptop cards, etc.). Transmitter power determines the range in which Bluetooth devices can operate, and devices generally fall into one of three categories: Class 1 is the strongest, which can operate up to 100m(330 ft), Class 2 (the most common type) is effective up to 10 m(33 ft), and Class 3 is the weakest, which does not exceed 1 m(3.3 ft).
8 Bands Jammer DeviceHow does Bluetooth work?
Bluetooth sends and receives radio waves in a band of 79 different frequencies (channels) centered around 2.45 GHz, separate from radio, television and mobile phones, reserved for industrial, scientific and medical use. Don't worry: your use of Bluetooth at home won't interfere with someone's survival machine, because the low power of the transmitter won't carry your signal that far! One of its biggest advantages is the short-range transmitter of Bluetooth. They use little to no power, and since they don't transmit great distances, they are theoretically more secure than wireless networks that work long distances, such as Wi-Fi (in practice, there are security concerns.)
Bluetooth devices automatically detect and connect to each other and can communicate with up to eight devices simultaneously. They don't interfere with each other because each pair of devices uses a different channel out of 79 available channels. If two devices want to talk, they randomly choose a channel and, if that channel is already occupied, randomly switch to one of the other channels (a technique called spread spectrum hopping). In order to minimize the risk of interference from other electrical equipment (and also to improve safety), pairs of devices are constantly changing the frequencies they are using, thousands of times per second.
When two or more Bluetooth devices share information, they form a temporary mini-network of computers called a piconet. Other devices can join or leave the existing Piconet at any time. One device (called the master device) acts as the overall network controller, while other devices (called the slave device) follow its instructions. Two or more separate piconets can also connect and share information, forming what is known as a decentralized network.
Is Bluetooth better or worse than Wi-Fi?
People are often confused about Bluetooth and Wi-Fi because at first glance they seem to do similar things. In fact, they are quite different. Bluetooth is primarily used to temporarily connect computers and electronic devices over very short distances, and is often used for brief or occasional communications using relatively small amounts of data. It's relatively safe, uses very little power, and connects automatically. Wi-Fi is designed to transfer large amounts of data between computers and the Internet, often over much greater distances. It can involve more complex security and typically uses higher power. Bluetooth and Wi-Fi are complementary technologies,
