Schools use cell phone jammers block cell phone signal

The development of science and technology has enabled smart phones to grow rapidly. Smart phones have become the products of many people. The mobile phones in the market are cheap, easy to purchase and easy to use. So many students now have their own mobile phones. In the Internet age, if they use a mobile phone to consult the data, then mobile phone is their important learning tools, but they are using mobile phones to play games, etc., this will bring important influence to their study. It not only affected the teacher's class, but also affected the study of other students, and more importantly, delayed their good study time. Although the school has banned the use of mobile phones, mobile phones have been brought into the classroom by students.

In addition, they used mobile phones to cheat on exams. The violation, which forced the school to install a cell phone jammer device, intercepted the phone's signal so that their phones could not connect to the Internet. During the examination, the mobile phone jammer was opened to prevent students from cheating, which ensured the fairness of the test. In a sense, school use of cell phone jammers is a wonderful thing.

WiFi key technology

In order to minimize the data transmission collision and retry send, prevent the disordered contention channel of each site, the wireless LAN adopts the carrier to listen multi-channel access/conflict avoidance protocol. The CSMA/CA communication method closely links the time domain to the frame format, ensuring that only one site is sent at a certain time, and the centralized control of the network system is realized. Before sending out the data, listen to the state of the media, wait for no one to use the media, wait for a period of time, then wait for a random period of time, still no one use, just send out the data. The chance of conflict can be reduced because the random time used by each device is different. Direct sequence spread spectrum technology is the main modulation technique adopted by 802.11b. Direct sequence spread spectrum technology is the technique of encoding and sending data using the 11 bit Chipping Barker sequence. The sending end adds chips (a string of binary code) to the bitstream to be transmitted via the spreader, which is called encoding; The original data can then be obtained by decoding the same chips at the receiving end. In the same throughput, direct sequence spread spectrum technology requires more energy than frequency-hopping technology; However, at the cost of energy consumption, it can also achieve higher throughput than frequency-hopping technology. 802.11b can achieve 5.5Mbps and 11Mbps with HR/DSSS technology.The wifi jammer is the wireless transmission band for wifi, which generates the same radio waves.

The development trend positioning function of 5G cellular network

The progress of science and technology, the requirement to the cellular network also gradually enhanced, the current 4 g networks don't seem to meet the needs of people on the Internet, so 5 g network development become one of the research topic of many countries. Currently, some cities in the world already have the use of 5G network, but these are still in the testing stage, and there is no widespread promotion, which is believed to be popularized in the near future. Positioning awareness is the basic requirement of many new markets, and 5G cellular mobile network has also included positioning function as an important module of network system design.The popularization of 5G cellular network is bound to have a great impact, so the 5G jammer will also be produced.

Examples of GPS trackers used in life

The use of GPS trackers is a lot we see in movies, mainly for police to track criminals. And then there are the cases where criminals are secretly installing to keep track of targets. In real life, the use of tracking device also has a lot of examples, such as taxi companies in order to understand the dynamic of the car, will be installed in the car GPS tracker, long-distance truck will install this tracker. Some drivers use the mini GPS jammer to block tracking signals to avoid such tracking.

Two things will lower your wifi network

WiFi networks tend to be slow. The competition between WiFi devices and the dynamic communication media of radio waves is a sensitive technology, and many Settings and situations may slow down.

Old wireless and security protocols

Setting up a wifi network with older security protocols significantly reduces the performance of wifi devices. This has nothing to do with the maximum support standards for access points and their commitments. For example, 802.11ac can support data rates of over 1,000 Mbps. However, if you configure WEP or WPA security, the data rate will be limited to 54 Mbps. This restriction is due to the use of the temporary key integrity protocol (TKIP) encryption method.Therefore, to ensure that the old WiFi security method does not reduce network speed, only WPA2 security is enabled using the advanced encryption standard. Do not choose WPA/WPA2 mixed mode or wpa2-tkip.

Use the 5GHz band

There are 11 channels in the 2.4 GHz band in North America, and only three non-overlapping channels are available with the default 20 MHz, and only one channel is provided with 40 MHz. Because adjacent aps should be located on different non-overlapping channels, the 2.4 GHz band may become very slow.The 5GHz band provides up to 24 channels. Not all aps support all channels, but all channels do not overlap if 20 MHz is used. With 40 MHz, there are as many as 12 non-overlapping channels. As a result, your AP and any other adjacent networks are less likely to interfere with the same frequency, and your wifi will be less disruptive and faster in speed.You should try to use the WiFi client as much as possible so that you can use the 5GHz band on the network to improve speed and performance. Using any frequency band on the AP can increase the chance of a dual-band client connecting to 5 GHz instead of 2.4 GHz.

Public service vehicles will be forced to install GPS systems

The dangers of driving a cell phone

Obstructing driving. The driver has a single hand in the driver's hand, which is a big hindrance to the vehicle. It has an impact on the speed control, the distance between the car and the driver's sight, which can easily lead to traffic accidents.

Distraction. Talking on a cell phone, the pilot is distracted, interfere with the driver on the road and surrounding environment of observation, once the emergency or emergency, will greatly weaken the driver of the strain capacity and the reaction time, easy to cause traffic accidents. A British traffic institute recently released by the test results show that the use of cell phones while driving, the brain's reaction speed is slower than the drunk when 30%, young people answer the phone is equivalent to a 70 - year - old drive the vehicle driving, driving in a car accident on the risk is higher than normal for driving more than four times, 70% of the fatal accident is caused by the driver inattention. And studies have shown that driving a phone can cause drivers to lose 20 percent of their attention, or even 37 percent if the call is important. At the same time, the driver who dialed the phone was 9 percent slower than normal and the brakes were 19 percent slower.

Narrow vision. While driving, the driver's vision becomes narrow and the peripheral vision is reduced. In a related test, a driver who was focused on driving had 50 percent more information than a distracted driver, creating a "blindness phenomenon." Drivers who use their phones are more likely to miss traffic signals, often unable to see bulletin boards and other signs.

Block traffic. The driving opportunities caused by distraction caused the speed to decrease, which affected the traffic rate of other vehicles and caused the traffic jam. According to the test, intermediate or high congestion road, the driver calls time-varying channel times reduces 20%, would also reduce the driving speed, in the very traffic jam, the driver cell phone than moving to use 3% of the time, the secondary flow, cell phone driver needs to spend 2% of their time.

If you find yourself in a car, the driver is calling, or checking your phone from time to time, you should remind him that you are doing this to protect the safety of the occupant and to protect your own safety. What would you do if he didn't listen? If you have a portable cell phone jammer, he will find that the phone has no signal and will drive well. This shows the importance of cell phone jammer for safety.

Driving and playing with your phone is far more dangerous than driving a cell phone. Life safety, therefore, for the sake of ourselves and others, suggest the driver friends, absolutely don't answer the phone while driving, even when using the bluetooth headset, but in the process of driving a call or will cause the driver inattention, accident probability is also relatively increases. The right thing to do is to stop by the side of the road and pick up the phone without affecting road traffic safety.

What is a jammer?

A jammer is an electronic jammer device that emits or retweets an electronic jamming signal, which is used to disrupt or deceive the enemy's electronics, to make it less effective and less effective.It emits electromagnetic waves to disrupt and disrupt electronic devices that normally work on enemy communications and radar equipment.

The jammer is divided into: to transmit pure clutter or clutter modulation signal to suppress the enemy electronic equipment, to make the communication signal fuzzy interrupt or to make the radar target echo to be obscured and to disable the detection signal capability of the clutter jamming machine, to receive the enemy signal after the proper processing and forwarding, to deceive, confuse, destroy the normal work of the enemy electronic equipment and the combined jammer with the above two functions.

Active jamming according to the interference pattern classification, can be divided into pressing type jamming and deception interference interference pattern, but the carrier of modern ship equipment active jammer or outboard active jammer can at any time between these two kinds of interference pattern transformation.

It would be a threat to our lives if we were targeted by criminals. Here are some tips on how to track your phone.

What is a radio jammer?

Radio jammer refers to occur in the process of radio communication, some electromagnetic energy through direct or indirect coupling into the receiving system or channel, lead to the decrease of the quality of the received signal and useful information to produce the error or missing, or even blocking the phenomenon of communication.

The radio jammer signal is primarily through direct coupling or indirect coupling to the electromagnetic energy of the receiving device or the system, which can affect the reception of the radio signal to receive the signal, resulting in performance degradation, deterioration of mass, loss of information, and even the interruption of the correspondence. Usually said, therefore, useless radio signal useful radio reception quality decline of or damage to the facts, known as the radio interference.

Classification of radio jammer

The radio jammer is generally divided into co-frequency interference, adjacent channel interference, out-of-band interference, intermodulation interference, block interference, etc.

The same frequency interference: the frequency of any useless signal is the same frequency as the frequency of useful signals, and the interference of the receiver that receives the signal from the same channel, is called the same channel interference.

Adjacent channel interference: jamming channel power is in the receiving end of the adjacent channel receiver, which is called the adjacent channel interference.

External interference: the harmonics of the transmitter or the stray radiation are caused by the disturbance in the band that receives the useful signal, called the external interference.

Intermodulation interference: mutual modulation interference is divide into mutual modulation interference and mutual modulation interference. Transmitter intermodulation interference means that multiple transmitter signals fall into another transmitter and modulate with each other under the nonlinear effect of the final amplifier, generating unwanted combination frequencies and interference with receivers with the same frequency of receiving signals. The radio interference of the receiver is that when the multiple signals are in the receiver at the same time, at the same time, the frequency is generated by the nonlinear circuit in the receiver's front end, and the intermodulation frequency falls into the receiver's frequency band.

Blocking interference: when a radio equipment receives weak and useful signal, it is subjected to interference of high interference signal on both sides of the receiving frequency and high frequency loop, and it is called block interference. The interference light reduces the receiving sensitivity, and the weight leads to the communication interruption.

Wifi alliance announced a new generation of WPA3 safety standards

Wifi network is the most important of the wireless network, we are to our life and work are very important, so its safety life safety as for us, it has some relation with our life. With the popularity of wifi, wifi encryption way was not too safe, it is apt to be attacked by hackers, the wifi network is connected encryption methods used by most, as early as in the recent loopholes then when it is attacked by hackers.

Because the encryption method of wifi is not too safe, and the appearance of the wifi jammer changes this phenomenon, it is the security of wifi that has been improved to a certain extent. Online news reports, claims that the wi-fi alliance will launch a new generation of wifi wpa3 encryption mode, it solved the existing problems in the connected, there is no trial, for safety we don't know, I hope it can better protection on the safety performance of wifi security! But for the current wifi security, it's safer to use a wifi jammer, don't you think?

What is an RF jammer?

The powerful rf jammer is the interference generated by the frequency of the signal received at the receiver or very close to this frequency, and the federal communication commission (FCC) sets out radio frequency interference standards for the electronic equipment to minimize such interference.

Radio frequency (rf) is a kind of high frequency alternating current, also is called electromagnetic waves. Rf interference is the interference of electromagnetic waves, like two frequencies of electromagnetic waves that can be interrupted at the same time by receiving the receiver, and in the distance from the launch pad, there will be harmonic interference, jamming the other receivers, transmitting the same frequency of electromagnetic waves that can disrupt the enemy's radio stations.

Why do prisons use signal jammers?

A prison is a place where criminals are held, and its safety concerns life. With the development of the Internet, most criminals commit crimes because of network crimes, and their use of Internet fraud. Prisons should not only guarantee the safety of the witnesses, but also protect the network and prevent criminals from contacting the outside world, thus making prison break or other things that endanger the lives of others.

With the development of science and technology, many prisons will now use the high power prison jammers to protect the prison network security, including the intercept signal, wifi, etc., to prohibit criminals from contact with the outside world, so that the criminal better turn over a new leaf.
