Two individuals from China employed remote-controlled signal jammers to perpetrate sophisticated thefts at highway rest stops. They were apprehended by law enforcement on the scene, which led to the discovery of a method for stealing funds from credit cards associated with a call center gang.
The police department in Chachoengsao has documented several theft occurrences at the Bang Pakong highway rest area, where vehicles have been forcibly entered and valuables, especially credit cards, have been taken. This has resulted in considerable distress for those traveling along this route.
The police in Bang Pakong, Chachoengsao, have partnered with the Central Investigation Police to rapidly pursue the criminals. They have gathered essential evidence from the CCTV footage available at each of the crime locations.
The individuals suspected of involvement appear to be Chinese, frequently utilizing a similar method of operation. They are organized as a gang with a distinct allocation of duties, notably between Zhang, who is 38, and Zheng, who is 31.
On September 15, the investigative efforts at the crime scene were concluded, leading to the joint arrest of two Chinese suspects at a highway service area in Khao Din Town, located in Bang Pakong District, Chachoengsao Province.
Realizing the clear pattern in the criminals' actions, the officers positioned themselves throughout the area for surveillance. When the two men arrived, the police decided to wait until they attempted to break into two vehicles before they revealed themselves and made the arrests.
The police then carried out a search of their room, revealing various items used in the crime, including a remote control signal jammers, three mobile phones, a shoulder bag, and they confiscated a car key, a vehicle, and other significant evidence.
The pair was charged with "jointly attempting to commit theft with a vehicle" and "illegally entering and residing in Saudi Arabia as foreign nationals." While Zhang denied the charges, Zheng accepted them. They were then transferred to the Crime Suppression Department for investigation.
The analysis showed that the gang would lie in wait near parking areas at highway rest stops. Upon seeing victims parked and ready to exit their cars, the first group of thieves would use cell phone blockers to interfere with the remote control signal, making it impossible for the victims to lock their vehicles.
Subsequently, another group of offenders would approach the victims and engage in phone conversations nearby to divert their focus, thereby preventing them from noticing that their vehicles were unsecured. Once the victims had left their cars, a different group of criminals would then open the doors and abscond with the valuables located within.
Furthermore, it was revealed by the police that a Thai woman, later confirmed to be Zheng's girlfriend, Ms. Ketfa Theeranat, 20 years of age, had been traveling in the same car as the suspect before being taken to the highway rest area.
In a search carried out in Ms. Ketfa Theeranat's apartment in the Rama 9 District, police discovered ketamine. She was subsequently arrested on the charge of "unauthorized possession of psychotropic drugs (ketamine)" and was taken to Makkasan Police Station for processing.
At the same time, law enforcement agencies discovered the methods the suspects used to extract money from the victims' credit cards. The card readers they utilized were believed to be associated with foreign retailers or areas of operation. This finding is consistent with the investigation's information, suggesting a possible connection between the criminal group and the call center gang involved in defrauding multiple networks.
We will continue our investigation into the case to ensure the accuracy of these findings.
The National Labor Relations Board (NLRB) has previously supported an employer's policy that prohibits the use of cell phones by employees at work, citing safety concerns. Additionally, the Federal Communications Commission (FCC) has recently upheld a fine against an employer for the use of signal jammers to obstruct employees from using cell phones during work hours.
Signal jammers are devices that obstruct, block, or interfere with authorized radio frequencies and communications, and their use is prohibited under the federal Communications Act of 1934, as amended (the “Act”), with certain limited exceptions. These mobile jammers represent a significant danger to public safety by preventing individuals from making emergency calls to 911, disrupting first responders' communications, and interfering with critical safety communications in both aviation and maritime environments.
The Act prohibits the operation or use of any device that is designed to transmit energy, communications, or signals through radio within the United States, except when such use is licensed or authorized. Additionally, it is stated in the Act that no individual shall intentionally or maliciously interfere with or disrupt the radio communications of any station that is licensed or authorized under this chapter or operated by the United States Government.
In addition, the Act asserts that "No individual shall manufacture, import, sell, offer for sale, or transport any device or household electronic device or system that does not comply with the regulations enacted under this section, nor shall they use a device that fails to meet the regulations established under this section." These regulations require that radio frequency devices must be authorized by the Federal Communications Commission prior to their utilization.
In conclusion, a jamming device cannot be certified or authorized because its primary objective is to interfere with or block authorized radio communications. The use of such a device would undermine the integrity of the nation’s communications infrastructure. Thus, a jamming device does not fulfill the technical standards required by the FCC and is not legally permissible in the United States.
In this case, the FCC Enforcement Bureau investigated a Texas warehouse business for using a signal jammer after receiving an interference complaint from AT&T. The business owner admitted to using a signal jammer to prevent employees from using their cell phones while working. According to the FCC, the business owner admitted that an AT&T representative had warned her son that using a jammer was illegal. Additionally, according to the FCC, the business owner told FCC agents that she had disposed of the jamming device and was unwilling to retrieve it for the agents or indicate where it was, but she did offer to sell the device to the FCC agents, but was rejected.
The Global Positioning System has become a fundamental aspect of our modern existence, providing precise positioning, navigation, and timing data for a variety of applications. GPS is crucial across different sectors, from aiding in daily commutes to enabling accurate military operations. However, the rising reliance on sophisticated technologies that can block GPS signals has concurrently increased the threat of signal disruption.
The modern gps jammer is a device designed to intentionally interfere with signals, thereby preventing receivers from accurately determining their location or obtaining reliable timing information. This disruptive technology presents serious risks in both civilian and military fields, potentially resulting in compromised safety, disruptions to operational GPS signals, and financial losses.
This comprehensive guide will analyze the intricacies of blocking technology, with the goal of fostering a deeper understanding of its effects, detection methods, and mitigation strategies.

In addition, we will delve into the efforts made to detect and counter jamming, focusing on the development of anti-jamming technologies and relevant regulatory actions. We will also investigate existing countermeasures and discuss future trends in addressing this changing threat landscape.
Understanding the dynamics of jamming technology is critical for preserving the reliability and security of essential systems that depend on GPS. By fostering awareness and collaboration, we can aim to develop effective strategies to counter the risks associated with jamming, ensuring the uninterrupted performance of GPS-dependent applications across a range of sectors.
We extend an invitation for you to engage with us as we delve into the complexities of jamming technology, assess its impact, and explore the various strategies employed to combat this continuously evolving threat.
Do GPS jammers exist: work principles
The Global Positioning System is a satellite-based navigation framework that delivers accurate positioning, navigation, and timing information to users around the world. This system functions by coordinating satellites and managing ground stations and receivers to establish precise location data.
What does GPS jamming do: technology explained
The different forms of GPS jamming devices are associated with intentional mechanisms of interference that disrupt the effective operation of GPS receivers. By transmitting strong signals in the same frequency bands designated for GPS, signal jammers can overpower or block weaker signals, making it challenging or impossible for receivers to acquire accurate positioning, navigation, or timing information.
Here are vital aspects to understand about blocking:
Last month, the U.S. Department of Justice filed a brief with the U.S. Court of Appeals, as noted by The Washington Times. The brief argues that authorities are permitted to collect cell phone tracking data without probable cause for any conceivable reason within a 60-day timeframe, which is essential for enabling emergency services to respond effectively during emergencies.
The government appealed to the district court, where the discussion addressed location information, including critical third-party business records that were not protected under data privacy laws. The judge determined that this was indeed a violation of the Fourth Amendment. The primary issue is that granting authorities access to personal location data for two months enables them to form a complete picture of an individual's life.This information can disclose a person's complete network of friends, their political affiliations, coworkers, religious beliefs, hobbies, and even negative habits such as gaming. Such sensitive data can be utilized to intimidate political opponents as well as to identify organized crime organizations.
One must also recognize an alternative viewpoint regarding this issue. There are individuals, including drug lords, sexual offenders, and suspected terrorists, who might exploit your phone or other communication devices to track your personal location. To protect your privacy and safeguard your location data, considering the purchase of an appropriate tracking gps jammer could be advisable.
After GPS devices were developed, they were quickly used by the public due to their positioning and navigation functions, not only in the civilian field, but also in the military and police field, and even among extremists. GPS can be used to protect your family and friends by tracking their real-time location and displaying it on your private map. Therefore, parents can always know where their children are. However, there are also disadvantages to using GPS. Thugs and other criminals will use GPS for illegal activities.
This report details an Ontario man and his family, who were frightened by the placement of a GPS tracker under their car by an unidentified individual. What precautions can be implemented to shield your vehicle from this type of threat?
There are also GPS trackers purchased under the guise of fleet tracking, but these devices can be used secretly and illegally on any vehicle. You can check your car thoroughly regularly, but I think it may be too troublesome for you, and it may not accurately find hidden GPS trackers. Professional devices generally have their counterparts, and the counterpart of a GPS tracker is a GPS signal jammer, which can block the positioning signal sent by the tracker and render it ineffective, so that you don’t have to worry about privacy leaks or security issues.
I strongly suspect that a business I frequent is interfering with cell phone signals. I have never been able to make any kind of call while there, and even text messages often fail to send. This is not related to my phone, as I have had the same problem with my last phone on another carrier and my wife's phone (also on Verizon).
My phone thinks the signal is great (3 or 4 bars), but can't even check voicemail. The problem persists - but goes away when I leave the building - until I'm about 10 feet from the front of the location. I suspect the building is made of lead or some other material, because I can pick up Wi-Fi signals (from Comcast, etc.) when I'm inside. I know we're talking about different frequencies, but I think most building materials that block RF do so somewhat indiscriminately.signal jammer
Anyway, I wonder if Verizon could come check it out. If they don't block it, I might have to try a new carrier.
I know how important it is to be able to rely on your service.
You mentioned that service resumed after leaving the building. Since our cell towers are located outdoors, there are many variables that can affect signal penetration, such as foliage and building materials. This is different from WiFi, which uses a router that allows the signal to be wirelessly accessible inside a building. We do offer network extenders, which can utilize your existing high-speed internet connection to enhance indoor service.cell phone jammer
Comcast WiFi is an outdoor public hotspot - not inside a building at all. Also, I have received strong signals from many off-site WiFi hotspots. I know this is not a foolproof test, but it at least shows that some RF can penetrate buildings very easily. Also, (while I also know this is not perfect) my cell phone reports a strong signal. However, as I said, I cannot even have a poor quality phone conversation. Also, it seems to affect a lot of people, as evidenced by how many people are out making or receiving calls. It only happens at this location. I didn't actually say it happens when I leave the building, I said it happens when I leave the building.
