From ancient times to today, security has always been an important aspect, such as military, network and many other fields. In this case, we need to use different types of security tools in different areas, such as WiFi jammers, which can protect the network security.

In order to ensure a safe environment, various safety measures have been taken in different locations and regions. For example, in factories, hotels, schools, and many other places, we can usually see that in many places, maintenance personnel of buildings should register first. All of this is to ensure security. We can see that security plays an important role in different regions and networks. Now, more and more people are accepting wireless network jammer devices.

All parties, including the media, are banned from flying drones

All parties, including media practitioners, are reminded not to fly drones anywhere in the country while the Movement Control Ordinance (MCO) is enforced through May 12.

Supt Rasha Azaldin Shafii, head of the drone unit of the Royal Malaysia Police, Air Operation (PGU), said flying drones without permission from the Malaysian Civil Aviation Authority (CAAM) is a violation of the Malaysian Civil Aviation Ordinance 2016 (MCAR 2016).

“Anyone who operates a drone without a permit can be punished with a minimum fine of 50,000 RM or a prison sentence of three years for individuals, while companies can expect a maximum fine of 100,000 RM.

“Please note that not all parties are allowed to fly drones unless they have permission from CAAM and the police,” he told Bernama.

He said throughout the implementation of the MCO, police had discovered four cases of illegal use of drones across the country.

“Further investigations into the cases are ongoing and the police are ready to use the drone jammer device to ensure that no drones are flown anywhere without authorization,” he said.

According to Rasha Azaldin, drones will be used specifically for nationwide aerial surveillance, including in areas under the expanded MCO.

“The use of drone technology has definitely been effective in making announcements and bringing back memories of COVID-19 throughout the MCO period,” he said.

On April 7th, CAAM authorized the PGU Drone Unit to operate the unmanned aircraft system or drones for surveillance and enforcement purposes during the MCO.

CAAM also announced that the drone operation would be led by the police in collaboration with the Malaysian armed forces and three private drone companies.

Anti-drone technology: what they do and how they work

Audio detection – drones emit a very specific sound. There are devices that can listen to the very specific frequencies of the whirring devices and work well up to a point. In a quiet, pastoral setting, these devices can detect an approaching drone with an accuracy of up to 500 feet. In a study conducted by Korean researchers and published in January 2017, these devices were tested in a real urban environment. When used in a noisy environment, audio detectors struggled to more accurately identify the incoming drones.

RF Technology – Drones use radio frequency to communicate with their operators. To keep the receiver and the transmission connected, they are paired with specific RFID chips that prevent other devices on the same frequency from overtaking the drone.

Jammers – Jammers emit electromagnetic noise using the radio frequencies that drones operate on and output information. In fact, they drown out the conversation between a drone and its operator. This is usually either 2.4 GHz or 5.8 GHz, which are unassigned public frequencies. This prevents jammers from interfering with manned aircraft, cell phones, public broadcasts, or other dedicated radio bands. drone signal jammer can be either stationary, mounted devices or built into highly mobile, gun-like devices that can result in a drone landing safely on the ground from where it may have intended.

Geofencing – Geofencing creates a barrier that surrounds airspace using a combination of a GPS network and Local Radio Frequency Identifier (LRFID) connections such as Bluetooth or Wi-Fi. This boundary is created using a combination of hardware and software to create a physical and invisible boundary that surrounds an airspace. Some drone manufacturers incorporate geofencing technology into their aircraft to warn pilots when they enter no-fly zones or restricted airspaces such as prisons, power plants, or airfields.

Video Detection – Video can be used in conjunction with other drone detection technologies to create and relay a visual record of a detected drone incident. Due to factors like weather or changes in season, video detection is not an ideal first line of defense in detecting incoming drones, but it can be a valuable tool for recording drone incidents for future reviews.

Thermal Detection – Thermal imaging is also not a good first line of defense when it comes to detecting drones, but it can be a helpful tool for locating drone operators in a remote area. For example in the smallest of spaces such as the area around a power plant. When a drone is detected in the air, thermal cameras attached to a drone operated by the power plant’s security staff can be used to locate the nearby operator of the intruding drone.

Radar Detection – Drones are often small, low-flying aircraft, making them very difficult to pick up on radar. Radar technology is ideal for finding manned large or long-haul aircraft flying in conventional airspaces. However, their skills are incapable of detecting drones well. When a drone crashed on the White House lawn in 2015, intelligence officials could only see it by sight as it was flying under the existing radar protection.

Knowledge of drone and 4G phone jammer week frequency

By Wikipedia’s explanation, FPV (first person view) is called RPV (remote person angle) or video navigation. It is a backpass facility with a built-in wireless camera based on a remote-controlled model airplane or car model, which is a new way of playing the model on the ground while watching the screen. Over the last few years, more and more drones have been used. This type of FPV utilization is most often seen.
The drone is actually a pilot’s eyepiece surveillance, a higher version of the drone incorporates two in-vehicle cameras and a portable jammer 4g in the pilot’s eyepiece. Can be 3D view

Wi-Fi Radio Blocker Let’s learn basic knowledge about week frequency

2.4GHz and 5.8GHz are the two most common frequencies for being connected to terrestrial radio transmitters and UAVs
The 2.4 GHz band is a common radio frequency. Often used to connect to ground-based transmitter axis aircraft and UAVs. If you know more about frequencies, you may know that the 2.4GHz band of unwanted cell phone jammers is also used in wireless computer networks. Therefore, it can be expected that there will be many accidents that lost control of the aircraft in densely populated residential areas with too many radio signals.

Another problem with drones is that they interfere with the vehicle’s navigation system. This is mainly due to the fact that the two transmitters worked together, one transmitting the guided wave number signal to the vehicle and the other transmitting the video signal to the driver.

The 5.8GHz band is used in 4-axis aircraft technology to avoid entanglement of the same frequency band with other RFs. This week frequency is found in the Dow Phantom model. Let’s see how UAVs work around wireless frequency issues

Phantom 1 This drone works in the 2.4GHz band. If you plan to participate in FPV, you will have to do it yourself using the 5.8 GHz frequency of the mobile deterrent jammer to avoid common problems.

If you use GOPRO or any other action camera’s unique wireless system, remember that the wireless option is turned off. Otherwise, it can interfere with the aircraft. The Phantom FC40 drone has adopted a radio frequency of 5.8 GHz. And since it has a single 3.4GHz system, you can send videos and photos to your pilot.

Phantom 2 Because this drone uses control at a 2.4 GHz radio frequency of a radio signal jammer, you have to use additional tools. Therefore, it transmits the FPV signal using the frequency of 5.8 GHz.

Phantom 2 Vision and Vision+ These two types of drones use 5.8 GHz and 2.4 GHz FPVs separately to take advantage of smartphone application connectivity and telemetry.

Portable jammer final conclusion
Therefore, if you bought a phantom UAV without a camera and other drones, you should use the 5.8 GHz frequency and FPV. By the way, it is worth noting that the RF signal is said to be a LOS mobile jammer or visual signal line. If there is no barrier between the UAV and the remote control, it will show that they cannot work. The best flying area of ​​the drone is directly visible to the naked eye. Otherwise, your drones could be damaged or lost.

Communication function suppression device. Development background and utilization of mobile phone suppression device

While convenience has improved due to the rapid spread of communication devices such as mobile phones and PHS, ringing tones of communication devices and noise caused by telephone calls have become a social problem in spaces such as theaters and halls where a quiet atmosphere is required. I will. In one hall, concerts by prominent conductors have even been interrupted. For this reason, the current situation is that operators such as theaters are strongly demanding the development of effective countermeasure technology.

To prevent ringing tones and calls from mobile phones, PHS, etc.
For this reason, there is a movement to prevent annoyance due to ringing sounds, etc. by using wireless equipment (mobile phone suppression device) that has the function of suppressing ringing sounds and calls from mobile phones.

OSCE announced suppression of signals from its UAV in Donetsk region

OSCE observers appealed to the liaison officer of the Ukrainian security forces, who denied the interference with the UAV of the OSCE mission by the military.

MOSCOW, November 5 – RIA Novosti. OSCE observers reported an incident involving the use of radio interference against an unmanned aerial vehicle (UAV) of the organization during its flight over the territory of the Donetsk region.

The Special Monitoring Mission (SMM) report says the incident took place on 3 November over the village of Chermalyk, 40 kilometers northeast of Mariupol. The OSCE unmanned aerial vehicle was exposed to unknown radio interference, disrupting the normal operation of the device, at 13.01 and 13.19 local time. After the UAV landed, OSCE experts deciphered the received data, which revealed that the aircraft’s GPS signals were being jammed by an drone jammer, according to the SMM report. The report notes that this is the third incident involving SMM drones in Ukraine since October 23.

A test launch of the first UAVs, which are supposed to monitor the ceasefire in eastern Ukraine, took place on 23 October. The OSCE reported that the UAVs will fly in three directions: south of Donetsk and to the Sea of ​​Azov, east – to the Russian-Ukrainian border, and also west – towards the contact line.

In April, the Kiev authorities launched a military operation in eastern Ukraine against residents who were dissatisfied with the February coup. According to the UN, as of October 31, the number of victims of the conflict exceeded 4 thousand people, more than 9 thousand were injured. With the mediation of Russia and the OSCE, the parties agreed on an armistice from September 5. In general, it is respected, but the parties periodically accuse each other of violating it.

Roskomnadzor has declared illegal the suppression of the cellular signal during the exam

Roskomnadzor confirmed that it considers it illegal to use means of jamming cellular communications during school exams. According to the press secretary of the department Vadim Ampelonsky, the State Commission on Radio Frequencies has not yet prepared the procedure for using “jammers” on the Unified State Exam. According to him, Roskomnadzor is obliged to fine schools that jam the signal of mobile phones without this document.

He noted that schools do not have the right to use “jammer” when passing the exam.

jammer signal device Powerful

The use of cell signal suppression devices without permits is prohibited under current legislation. Including because this can interfere with the cellular signal, the channels of the police, army and special services, – he explained. – And if such illegal use is detected, the territorial bodies of Roskomnadzor interacting with the radio frequency service are obliged to suppress it.

At the same time, Ampelonsky admitted that “in some cases, the use of means of suppressing cellular signals is appropriate.” He confirmed that Roskomnadzor discussed with Rosobrnadzor the issue of protecting exams from cheating using mobile phones and radio headphones.

A draft decision of the State Commission on Radio Frequencies was prepared, which provided for the development of specific parameters of both the suppressors themselves and the signal emitted by them, – said Vadim Ampelonsky. – The proposed solution provided for the possibility of using the suppressors in closed rooms at the direction of the federal executive authority. If we are talking about schools, then it could be Rosobrnadzor. And at the same time, the power level of the suppressor signal should not exceed certain values ​​and should not interfere.

However, the draft decision was never adopted. Ampelonsky expressed hope that the document will be approved by the end of this year.

Recall that devices that suppress the cellular signal have been used during the exam since 2011. Typically, regional government examination boards “recommend” school principals to purchase and use such devices. As Kommersant reported, this year the regional department of Roskomnadzor in the Tver region fined several schools for using jammers.

How to make your own cell phone signal blocker

Cell phone signal jammer is installed in quiet areas, such as schools or universities, but… how exactly does this instrument block cell phones? These locking instruments prevent mobile devices from receiving signals from base stations. While it may sound like a complicated process, making your own phone blocker isn’t that difficult. However, you should know that in many countries (including the United States) they are illegal and subject to large federal fines, in addition to criminal prosecution. Who knows what could interfere …

phone jammers

1. Understand the principles of operation. This cellular signal blocker operates with the GSM800 frequency, since most mobile phones use it to operate. The VCO selected is a sweeping oscillator, which is very effective but can be difficult to build for beginners who do not have good RF testing equipment.
As a noise source you can use a 45MHZ clock oscillator, which is the local oscillator port located on the mini-circuit mixer. There is also an impedance matching network for the local oscillator signal to pass through. It is used to match the impedances of the oscillators and the mixer port.
The RF input (which is the mixer port) connects to the first 800MHz cell antenna, and the RF output is sent to the mini-circuit amplifier. This amplifier increases the output power by 15-16 dbm. Then the amplified signal is sent to the second antenna of the cell phone.

2. Consider how it works. All cell phones using GSM800 always separate the transmitted and received frequencies at 45MHz. So when the mobile phone tries to call, it is blocked by its own signal coming back to you! Isn’t it cool? So when the chatter of the phone irritates you, turn on the blocker so that the criminal hears his own voice on his cell phone. By the way, you can also use this cell phone signal blocker to block any cell-based tracking system that uses your GPS to track and record the movements of your car. And you can probably block improvised explosive devices that are detonated using cell phones. The mixer that is used is designed to work up to 600 MHz, but in this case it works very well. The RF amplifier does its job quite well even though it consumes additional power.

3 Use an old aluminum box as a frame for the jammer and some old UHF connectors from a Motorola cell phone for input and output.

4 Connect the RF connectors to the circuit.

5 Use a nine-volt battery and a voltage regulator to power all components. Place the battery inside and separate it from the rest of the components using foam rubber.
Flip the on / off switch at the top.

6 Screw the input and output antennas (also from an old Motorola cell phone) to the UHF connectors.

7 Your cell phone blocker is ready. Enjoy it!

DJI launches drone self-interception system

The recent frequent occurrence of drone accidents shows that drones as a consumer-grade technology product have continued to gain popularity. At the same time, the level of safety of drones is also increasing.

he Verge reported that the famous Chinese drone manufacturer DJI launched a new self-intercepting software system “Geospatial Environment Online” (Geospatial Environment Online, GEO) this week, which can prevent DJI drones from flying in No-fly zone.

uav drone blocker

The GEO system allows users to know where drones will be restricted, whether it is due to regulatory requirements or safety issues. This is DJI’s innovative approach to respond to the Federal Aviation Administration (FAA), which has been calling for more rules for drone flight over the past year.

According to The Verge, the drone jammer can prevent DJI UAV systems from flying in no-fly zones such as airports and Washington, D.C., and can also let users know which airspaces are temporarily restricted from flying, such as areas close to forest fires or major sports events. Sensitive areas around prisons and power plants are also restricted in the system.

However, users of DJI drones can still temporarily exit the GEO system and unlock some flight restrictions. However, if an accident occurs, the user will be checked by the regulatory authorities. Users who want to temporarily unlock must have a DJI-certified account and have registered credit card, debit card or mobile phone number information. If the drone is found flying in an unauthorized airspace, the supervisory authority can find the person in charge. However, drone users cannot close all flight restrictions, and areas such as Washington, DC are still completely banned from flying.

On the necessity of using mobile phone signal jammer in important occasions

Today’s mobile phones are becoming more powerful and smarter. You can not only make calls, send text messages, but also social chat through your mobile phones. Some social software is also more powerful, you can do live broadcast, you can receive video with the other party on the spot, and you can also record… Then there is a kind of rigor in important occasions, if it is some business secrets to hold meetings or discuss For any plan, in order to avoid the transmission of internal and external messages, and to protect the security of this plan, a cell phone jammer can be used.

portable wireless signal jammers

Commercial competition is getting stronger and stronger, especially some commercial secrets. After all, the competition is fierce. When there are any new tricks or new things invented, or when there is a commercial plan, it must be kept secret from the outside. It cannot be ruled out that internal staff have been bought by other companies. In this case, when discussing plans or meeting in secret, employees may leak secrets with other companies. You can use a mobile phone signal jammer. With the jammer, you can avoid internal leaks.

When discussing important secrets, a mobile phone signal blocker can be used just in case. If there is a recording, it can be blocked, and the order of the meeting can also be maintained to avoid the interference of the mobile phone. Chengdu Saiyue Communication Technology Co., Ltd. has focused on the development, production, sales and engineering installation of jammers for more than 10 years. It is one of the few most professional signal jammer manufacturers in China. The Chengdu Saiyuetong brand wireless signal jammer system provides mobile phone jammers | GPS signal jammers | wireless WIFI mobile phone signal shielding | one-stop signal shielding solutions for prisons, detention centers, schools, examination rooms and other important places.

Truth|Does the cell phone signal jammer affect the human body?

Generally, people have inexplicable rejection of wireless devices. They always think that the signals emitted by wireless electronic products will affect their health. So, today, let’s talk about whether cell phone signal jammers have any impact on human health.

First of all, concerns about radiation from electronic products have always been a controversial issue among the people. Because we know that all electronic products have radiation, but different products have different amounts of radiation. Generally, the equipment of regular cell phone jammer will be monitored by the National Center for Disease Control and Prevention before leaving the factory. At present, the National Standards of the People’s Republic of China “Electromagnetic Radiation Protection Regulations” (GB8702-88) and the People’s Republic of China Environmental Radio Wave Hygiene Standards (GB9175-88), according to the national standard radiation level requirements, are allowed only after manufacturers who produce electronic products have passed the test. sell. And after installation on site, it also needs to undergo radiation testing by the National Center for Disease Control and Prevention. For engineering sites that meet national standards, the National Center for Disease Control and Prevention will issue an electromagnetic radiation testing report.

4g cell phone jammer

After testing, electronic products that meet the national standard radiation level requirements have no effect on the human body, so there is no need to worry about whether the signal radiation of the mobile phone signal jammer will affect the health of the body. In addition, according to the conversion of relevant data, the amount of radiation from the mobile phone to the human body should be the largest, and the radiation from the shield to the human body is almost negligible compared with the radiation of the mobile phone we use daily.
