Cell phone signal blockers are already very common information confidentiality devices in some special occasions, but their working conditions have also attracted everyone's attention. In addition to being able to block cell phone signals, can such devices also block wifi signals? These questions are also questions that many netizens want to know. To fully understand such questions, we must first understand the working mode of cell phone signal blockers and the interference frequency bands and the left and right frequency bands of WIFI signals. Now let the professional technicians of Chengdu 8341 Information Technology Co., Ltd. explain the answers to you.

To understand how to block wifi signals and the working method of mobile phone signal blocking, you need to first understand which frequency bands need to be blocked. At present, there are three major network operators in my country: China Mobile, China Telecom, and China Unicom. The signals of these three operators have wide coverage and use many frequencies. Therefore, if the cell phone signal blocker wants to meet the requirements of shielding the network, it is necessary to target the frequency bands of these three operators. The three major operators have 2G, 3G, 4G, and 5G frequency band networks. These frequency bands are as follows: CDMA870MHz-880MHz, GSM935MHz-960MHz, DCS 1805MHz-1920MHz, TDSCDMA2010MHz-2025MHz TD-SCDMA 2010MHz-2025MHz, CDMA2000 2110MHz-2125MHz, WCDMA 2130MHz-2145MHz, 4G1 2300MHz-2390MHz, 4G2 2555MHz-2655MHz. However, there are two frequencies currently used for wifi signals: 2400-2483MHz and 5725-5875MHz. In fact, it is very simple. The cell phone signal blocker does not block wifi signals. It only targets mobile networks. After the network sent by the base station is interrupted, wifi will also lose its function.

It is not difficult to use a cell phone signal blocker to block wifi signals. The cell phone signal blocker originally comes with a 2400-2483MH7 frequency, so it can block a lot of 2.4G wifi frequency signals, but the 5725-5875MH7 frequency band is gone. Because the R&D cost of the equipment is too high, many customers cannot accept it.

Nowadays, the popularity of car GPS devices has provided us with a great deal of convenience. At the same time, car buyers are also worried that they may encounter the risk of unauthorized people tracking them through GPS.

With the rapid development of mobile communication technology, cell phones have become an indispensable tool for people's work and life. Intelligent communication methods have brought us convenient, convenient and accurate comprehensive services, but also brought about increasingly serious air pollution and confusion in life, learning platforms and network security risks. Intelligent management and control of mobile phone communications in designated areas and special environments is undoubtedly the main way to solve the current problem of confidentiality and network security and eliminate the partial disruption of public order. Analysis of the 5G signal jammer for cell phone supervision in prisons.

Prisons are places for detaining prisoners. There are many criminal gangs in prisons. Improving the security system is the top priority for improving prison management capabilities.

Nowadays, the use of mobile phones by prisoners in prisons is very common. Some prisoners in the prison use illegally trafficked mobile phones to make calls, send messages, surf the Internet, obtain materials, threaten witnesses, and even form gangs and organize jailbreaks in the detention center. In recent years, many jailbreaks have been related to mobile phones. In order to better adapt to the new situation of prison security work requirements, enhance prison high-tech safety awareness, improve prison innovation management level, promote the construction of intelligent cells, it is imperative to establish a truly scientific, meticulous, stable, advanced, and practical prison mobile monitoring system.

2.4GHz wifi jammer for home life and conference rooms

Mobile and Wi-Fi Blockers are designed to keep you safe and protect your personal space from unwanted phone calls, interception of communication channels and data leakage on mobile internet sites, Wi-Fi - Fi and mobile Bluetooth internet rely on tiny cameras and system vulnerabilities. In addition, when a signal jammer is used, the movement of most wireless devices will be blocked, 99% of which devices operate at the 2.4GHz frequency.

Typically, this type of Wi-Fi blocker is used to prohibit or do not want the use of mobile phones and Internet technology (in an office or conference room), as well as for personal protection of confidential data (such as in an apartment or house). The 2.4ghz blocker converts into wireless communication interference in the GSM800/900/1800/1900MHz, 2100Мгц3G, LTE-4G800/2600 and 2400MHz frequency bands, using Wi-Fi/Mobile Bluetooth Internet and most agent surveillance cameras and system vulnerabilities. The jammer is strictly prohibited from connecting at all and cannot transmit any information through any device using these frequency bands. The effective blocking range of Wi-Fi signals is up to 20 meters, which depends on the distance from the base station or other transmitting modules, the silent connection you want, the battery pulse signal, and even the materials in the building or the materials you want to place. Place mobile device model specifications.

Before first use, the antenna must be firmly fixed to the appropriate RF connector of the 2.4GHz signal jammer, and then charge the battery for a few hours or connect it to a power outlet. The battery pack can run on its own for up to 2 hours on a single charge, but it can continue to run if the inhibitor is connected to the charger. This suppressor has a traditional brown shape and is equipped with additional buttons, sensors or indicators. It is easy to operate and the audio equipment is not heavy, so it can be used as a positioning device. You can also define the style and install it in any room you want. Sell, purchase and use 2.4GHz power jammers and cordless network interceptors to ensure personal security and stay within your personal property without violating the law. However, it is worth remembering that you do not have the right to block the use of services in public areas by third parties through various signal interruption methods.

Many customers often call and say: I need a new cell phone signal jammer that can shield a radius of 50 meters, a distance of 500 meters, and a radius of one kilometer, and it must be shielded by China Mobile, China Unicom, and China Telecom.

Is there anything wrong with the customer's requirements? No problem, and they also put forward specific distance requirements, but can it be achieved? The answer is: it is relatively difficult to achieve.

Why does this happen? Isn't the main parameter of the signal jammer marked with its own shielding distance? Can't it be achieved by placing more units according to this distance?

In fact, otherwise, the customer's requirements will be wrong, but they may not know that the shielding plan of the signal jammer is not a number. This forces us to understand the principle of the signal jammer:

During the operation, the signal jammer scans the low-end and high-end of the wireless channel at a certain speed. The scanning speed can cause error interference in the cell phone receiving the message format signal, causing the mobile phone to be unable to detect the normal microwave heating signal information sent from the communication base station, and inevitably prevent the mobile phone from establishing a connection with the communication base station within the overall plan, achieving the purpose of shielding the signal.

Simply put, the power emitted by the cell phone signal jammer interferes with the power of the mobile phone receiving the communication base station. After all, there is a competitive relationship between the jammer and the communication base station. If the signal strength of the signal jammer is lower than the wireless channel power transmitted by the communication base station to the mobile phone in the natural environment at that time, then the jammer cannot be shielded. Only when the output power of the signal jammer exceeds the output power transmitted by the communication base station to the mobile phone can it be effectively shielded. Therefore, any signal blocker will show different shielding distances when used in different signal environments, and it will be different for China Mobile, China Unicom and China Telecom, because the density of base stations built by these three operators, the direction of base stations and the power of base stations are unlikely to be the same.

In other words, how long the cell phone signal blocker can shield is not only related to its own signal strength, but also to the distance between base stations in the application environment (base stations are not limited to large-scale signal transmission towers built on the ground, but also signal expansion antennas on the roof and signal expansion and transmission in some buildings). Another important factor is the obstacle. If it is a metal material, it will be blocked directly; if it is a load-bearing wall of a concrete structure, it will attenuate by at least 10 times after passing through; if it is a wood board or glass material, the attenuation after passing through is relatively small.

Therefore, next time there is a customer who asks how long the shielding distance is, be sure to ask the distance between base stations in the environment, and then whether it is used indoors or outdoors, whether it needs to pass through the wall, etc. Customers can leave messages online to learn how to use the signal jammer. Only by understanding these can they choose the appropriate signal jammer.

To understand the answer to the question of whether the 5g signal blocker has an impact on the Internet access of laptops, we must first understand the image frequency band of the cell phone signal screen and the frequency band used by the laptop network.

First of all, if the frequency band affected by the 5g signal blocker overlaps with the frequency band used by the laptop network, it will affect the network function of the laptop. Let's take a look at the frequency band affected by the 5g signal blocker. Because the signal coverage of Chinese operators is wide and the application style is diverse, the 5g signal blocker must achieve the effect of shielding major websites. Generally, it will effectively shield and affect the 2G, 3G, and 4G frequency band signals, Wi-Fi, GPS, and Bluetooth signals.

After understanding what frequency bands the 5g signal blocker introduced above can affect, let's take a look at what frequency bands are used on the laptop network.

Notebooks generally have two ways to access the Internet, one is the cable network, that is, the Ethernet network, and the other is the wireless network. At present, 5g signal jammers cannot block or affect the cable network, so here we mainly summarize the frequency bands of laptop wireless networks. According to the current classification of laptops on the market, wireless networks support single-frequency and single-frequency. The so-called single-frequency refers to only supporting WiFi2.4 frequency band to connect to the network, while single-frequency means supporting WiFi2.4 and WiFi5.82 frequency bands to connect to the network. Most laptops only support single-frequency, and some high-priced or more conscientious ones will be equipped with single-frequency networks.

After understanding the working frequency bands of 5g signal jammers and laptops, people with eyes may immediately understand whether 5g signal jammers have an impact on laptop networks. In short, mobile phone signal jammers may have an impact on laptop networks.

In fact, it needs to be subdivided into the following situations:

1. The 5g signal jammer has no WLAN control module and has no effect on the laptop wireless network;

2. The 5g signal jammer supports the WiFi2.4 frequency band, which affects the single-frequency laptop wireless network and does not affect the single-frequency laptop wireless network;

3. The 5g signal jammer supports the WiFi2.4 and WiFi5.8 frequency bands, which will affect the wireless network function of the laptop.

Does the 5g signal jammer have any effect on the laptop wireless network?

Based on the above detailed understanding, the 5g signal jammer also has an answer to whether it has an effect on the laptop network. The 5g signal jammer is likely to have an impact on the laptop wireless network function. For those customers who have the need to use 5g signal jammers for shielding, it is necessary to equip the laptop with an Ethernet interface cable for connecting to the external network for work, so that the effect of taking care of both fish and bear's paw can be achieved.

In many occasions in daily life, such as exams, meetings, etc., it is very inappropriate to use mobile phones. At this time, in addition to paying for the mobile phone in advance, you can also use cell phone signal jammers to block cell phone data signals and Wi-Fi signals for special occasions. Without cell phone data signal and online data signal, we will not play with mobile phones, which achieves the desired effect very well.

The creation of cell phones has indeed increased the distance between people and provided great convenience for your daily life. However, with the spread of mobile phones, everyone has reached an inseparable state, which has brought great disadvantages to many occasions. Hence the huge shopping malls of cell phone signal jammers.

So, where arecell phone signal jammers suitable for? The application areas of cell phone signal jammers are still very common. Some confidentiality organizations, state agencies, colleges and universities, etc. can learn more about it.

1. Various large, medium and small examinations

Fairness and justice are the key rules of social development, and there are many exams that need to be faced in life, ranging from primary school to junior high school, junior high school to high school, and national-level exams such as college entrance examinations and civil service recruitment exams. In order to prevent students from cheating, in In various large, medium and small examinations, cell phone signal jammers and other means must be used to block information in the examination room so that it cannot reach the cell phone and cannot communicate. Online needs, then it can also be a good way to guard against students' cheating practices.

2. National defense areas, cells, and detention centers

In some areas that require strict control, such as defense centers, prison cells, detention centers, etc., the level of information confidentiality is very high. Mobile phones should be strictly monitored, and mobile phone signals should be blocked in areas such as defense centers, prison cells, detention centers, etc. This can greatly prevent leaks. In addition to the three major types of mobile phone signal jammers described above, in other areas where phone calls are strictly prohibited, such as gas stations, petrochemical plants, hospitals, etc., the effect of installing a mobile phone signal jammer is also very ideal.

3. State agencies and enterprises

State agencies, enterprises, etc. also have demand for cell phone signal jammers. The frequency of meetings held by party building agencies, government agencies, enterprises, etc. can be said to be very high. In order to allow participants to gather more at the meeting and learn the spirit of the meeting more deeply, it is also necessary to pay attention to the use of mobile phones. When leading cadres hold meetings, they turn on cell phone signal jammers to block mobile phone signals. The leading cadres talk happily and the people below listen attentively.

When using a cell phone signal jammer, you can choose it according to the applicable situation. If the location is relatively large, you can use a cell phone signal jammer with too large an output power.

There are some products that are very similar in appearance but different in quality. In the process of purchasing a GPS jammer, you can really have a reasonable way to judge the quality of the device. On this premise, before making the selection This is the basis for everyone in the purchase process, but some people do not fully understand how to judge the quality during the purchase process? There are many ways to do the same thing. After you can accurately carry out the control, you can obtain the required results naturally.

In many cases, some laymen don't know how to judge a GPS jammer, at this time you can immediately grasp the well-known brands. If the brand you choose is very good, then the quality can be guaranteed, but if the brand we choose is not actually very good, the quality will certainly be questionable, so for these laymen In other words, you can carefully choose products from well-known brands, which may be more helpful.

The eyes of the people are bright. When you are in the process of purchasing a jammer through some methods, you need to truly understand their user reviews and take a proper look at what other people’s reviews are like. , you can learn more about all aspects of information in detail, and understand everyone’s comments. If others’ judgments are particularly good, it means that the quality is sufficiently guaranteed, so if you are making a choice In the process, we need to consider things in this field. Therefore, only by ensuring product quality can we bring better application effects to ourselves.

There are many different types of GPS jammers on the market. If you are not sure how to make a decision during the selection process, we can actually compare different devices. In the process, you can understand the advantages and disadvantages of them. Even in bad situations, you can still make the right choice, which is a good way for everyone. Therefore, when everyone makes a choice, we should do a good job of comparing these products, because Only in this way can you further care about clarity and make corresponding choices. Learning to distinguish quality is also the prerequisite and basis for making choices. I hope everyone can do better.
