The most widely used mobile phone standard currently is our gsm global system for mobile communications. GSM standard equipment accounts for more than 80% of the current global cellular mobile communication equipment market. It is widely used and maybe we are familiar with the use of mobile phones. That's right, phone calls and text messages rely on GSM to provide a stable network data type. However, there is much more to GSM networks than we know. The gsm module is one of the directions that many electronic manufacturers are familiar with and carefully researched. It is used in many aspects of life, but we don't understand it. Common access control security systems and GSM network car security systems and robots have been applied to gsm modules.

GSM also supports indoor coverage. The power of the outdoor antenna can be distributed to the indoor antenna distribution system through a power divider. This is a typical configuration used to meet high-density call requirements in homes, which is common in shopping malls and airports. Indoor coverage can also be achieved via wireless signals within buildings, but this improves signal quality and reduces interference and echo.

First, GSM is the basic network band used for mobile phone voice communications and SMS services. It is known that inappropriate use of mobile phones is serious and using mobile phones in public places can cause a significant noise impact to other people. Can you imagine how annoying it would be when you are reading and relaxing in silence and suddenly someone is making a phone call? I agree. We don't like to be disturbed when we need to be quiet.

The gsm network band is very important for the use of electronic devices. Therefore, in many places where the use of mobile phones is prohibited, jamming equipment that blocks basic mobile phone communications is installed. This is what we often call GSM jammers.

When purchasing a gsm jammer, we need to understand our own needs. For example, in addition to the gsm network, we need to block the signal type and whether it is necessary to block the 3G and 4G network bands. In this way, we can buy a cell phone jammer that blocks all cell phone signals. Additionally, we purchase electronic jamming equipment and we need to consider where we use it. Portable jammers allow us to use them indoors and outdoors, while desktop signal blockers use a variety of antenna designs. As the name suggests, they will have a wider range of uses, not just for individuals but also in prisons, courthouses, schools, and other larger venues, as they have a wider interference radius and more types of signal shielding.

For personal use, I recommend a 4-antenna portable gsm jammer. It's enough to meet your needs and provide you with a quiet reading environment wherever you need to keep quiet. For a company or important organization, the powerful multi-antenna desktop jammer will be your best choice. It stands out in terms of functionality and interference radius and is considered sufficient for large-scale applications.

1. Take out the screen host from the packaging box.

2. Hang the signal jammer on the wall or corresponding location. The recommended installation height is 1-1.8 meters.

3. First connect the power cord to the host, then plug the power cord into the mains socket, and then turn on the power switch. The work indicator light on the host lights up to start working.

4. For large and small spaces, the installation location is as shown in the figure below.

1. The effective coverage range of the shield is the circular area of the shield, so when using it, pay attention to the correct placement of the shield to avoid blind spots in the shielding.

2. The shielder should be placed in a well-ventilated place, try to avoid large objects, and avoid strong electromagnetic sources of strong heat sources to ensure the shielding effect and long-term stable operation.

3. When the shielder is working, no other objects should be placed on top of it to avoid affecting the shielding effect and damaging the machine.

4. When the cell phone jammer is not in use, the power supply should be cut off in time to avoid affecting the normal use of the mobile phone.

5. When using the shield outdoors, pay attention to waterproofing.

6. When the area of the site used is larger than the effective screen range, it is recommended to use multiple jammers to be installed in a honeycomb manner to ensure the screen effect.

7. Please stay away from corrosive gases and liquids, and be dustproof and moisture-proof to avoid accelerating the aging of the internal components of the equipment.

8. When placing it outdoors or in the wild, you should pay attention to adding protective devices in environments where rats, ants and other destructive animals are infested.

1. The shield is a maintenance-free device and requires no maintenance.

2. When wiping the surface, avoid using chemical solvents and avoid water entering the machine.

3. The shielder should be stored in a dry and ventilated place to avoid long-term exposure to salt spray and harmful gases.

4. The jammer has a three-year warranty, free replacement within one year, and lifetime maintenance.

It can be said that mobile phone signal jammers have brought great help to our lives, but we don’t know much about the specific knowledge of mobile phone signal jammers. Let’s learn about the mobile phone jammers we usually encounter. Frequently asked questions about signal jammers.

(1) When the mobile phone signal jammer is working, why do some mobile phone signal indicators show that there is still a signal?

Answer: This is just an illusion. In fact, the mobile phone could no longer communicate at this time. When you press the unplug button at will, you will find that there is no signal indication at all on the signal indicator.

(2) Will the mobile phone signal jammer interfere with the normal operation of other electronic devices?

Answer: No. This is because the electromagnetic signal emitted by the cell phone signal jammer is completely within the mobile phone operating frequency band specified by the country and will only block mobile communications. And this signal is always in a relatively static state and will not affect any electronic equipment.

(3) Are mobile phone signal jammers harmful to the human body and mobile phones?

Answer: Please rest assured that the electromagnetic signal intensity emitted by the mobile phone signal jammer is very weak. Test data shows that this signal intensity is far from causing harm to the human body. At the same time, the mobile phone signal jammer only blocks the forward signal of the mobile phone so that the mobile phone cannot contact the base station, so it will not cause any damage to the mobile phone itself.

(4) Is there any difference in the effective shielding distance of mobile phone signal jammers when used indoors and outdoors?

Answer: Yes. The effective shielding distance (30-40 meters) of a mobile phone signal jammer generally refers to the indoor distance. In outdoor open areas, the effective distance of shielding can reach several hundred meters. It should be pointed out that whether it is used indoors or outdoors, the effective shielding distance of the jammer has a certain relationship with the environmental conditions at the time, such as the distance from the base station, the placement location, etc. Therefore, when using a mobile phone signal jammer, this factor should be fully considered to avoid shielding dead spots that will affect the shielding effect.

(5) The case of the mobile phone signal jammer becomes hot after working for a period of time. Will working for a long time damage the machine?

Answer: Thank you for your attentiveness. This is a normal phenomenon. In terms of design, we use the thermal conductivity of fans and corrugated thickened aluminum alloy thermal strips to assist in heat dissipation. This ensures stable work for a long time. Therefore, the machine will not be damaged if the casing becomes hot.

Nowadays society, mobile phone is our daily essential items, almost manpower a mobile phone gives us a lot of convenience, but sometimes also cause a lot of inconvenience, which occasions need to avoid mobile phones, need to use cell phone signal jammer?

School is a place to study, students addicted to mobile phones and classroom "small actions" greatly affects the academic, many schools will take to confiscate the mobile phone handed over to the way of mandatory education, but this not only greatly harms the self-esteem of the students, but also allows students to lose contact with parents in the outside world, the use of mobile phone signal shielding, can be in the classroom to learn!

Of course not, for these phenomena, the use of mobile phone signal blocker to block all contacts between prisoners and the outside world, to prevent prisoners from serving their sentences during the unlawful acts, improve the overall control of the security agencies. In fact, mobile phone signal blocker applicable scene is quite wide, because of their own signal shielding needs, many units will purchase and use mobile phone signal blocker. The use of mobile phone signal shielding must be consistent with their own needs, but also have to take into account the laws and regulations, have to be reasonable use of shielding, not because of their own shielding needs to the operator's communications, and even the base station to cause adverse effects.

If you want to understand the answer to the question of whether a mobile phone signal jammer has an impact on laptop Internet access, you must first understand the interference frequency band of the mobile phone signal jammer and the frequency band used by laptop computers to access the Internet.

First of all, if the interference frequency band of the mobile phone signal jammer overlaps with the frequency band used by the laptop to access the Internet, it will affect the laptop's Internet access function. Let’s first take a look at the interference frequency band of cell phone jammers. Due to the wide signal coverage of domestic operators and the wide range of application standards, mobile phone signal jammers must achieve the effect of blocking the entire network. Generally, they will effectively block interference for 2G, 3G, 4G band signals, WiFi, GPS, and Bluetooth signals.

After understanding which frequency bands the mobile phone signal jammer introduced above can interfere with, let’s take a look at the frequency bands used by laptops to access the Internet.

Laptops generally have two ways to access the Internet, one is wired Internet access, that is, Ethernet network port Internet access, and the other is wireless Internet access. At present, mobile phone signal jammers cannot block or interfere with wired Internet access, so here we mainly describe the frequency bands for laptop wireless Internet access. According to the current classification of laptops on the market, wireless Internet access supports single-band and dual-band. The so-called single-band refers to only supporting WiFi2.4 frequency band to connect to the Internet, while dual-band supports WiFi2.4 and WiFi5.8 frequency bands to connect to the Internet. Most laptops only support single-band, and some that are more expensive or have more conscientious configurations will be equipped with dual-band Internet access.

After understanding the respective working frequency bands of signal blockers and laptop computers, sharp-eyed people may immediately understand the issue of whether mobile phone signal jammers have an impact on laptop Internet access. Simply put, mobile phone signal jammers may affect laptop Internet access.

1. The mobile phone signal jammer does not have a WLAN module and will not affect the wireless Internet access of laptops;

2. The mobile phone signal jammer supports the WiFi2.4 frequency band, which affects the wireless Internet access of single-band laptops but does not affect the wireless Internet access of dual-band laptops;

3. The mobile phone signal jammer supports WiFi2.4 and WiFi5.8 frequency bands, which will affect the wireless Internet function of the laptop.

Through the above detailed understanding, we have the answer to whether the mobile phone signal jammer will affect the laptop's Internet access. The mobile phone signal jammer may affect the laptop's wireless Internet access. For those customers who need to use mobile phone signal jammers for shielding, they need to equip laptops with Ethernet cables for connecting to external network offices, so as to achieve the best of both worlds.

Generally speaking, many places do not have clear legal regulations on signal interference devices, but for our use, we should also understand the relevant precautions, including the maintenance of equipment performance, and where I can use it. Among our common cell phone jammers, signal jammers prohibit the use of mobile phones, prevent harassing calls, and prevent mobile phones from ringing, while GPS satellite positioning jammers protect the whereabouts of vehicles, prevent tracking, and protect location privacy.

Some things you need to pay attention to when using cell phone jammers in daily life

The interference radius of the signal jammer sold online may be related to the specific location of your use, and sometimes it cannot reach the required range, which may be affected by the surrounding environment. You should use a signal jammer that is easy to carry and blocks interference, it can protect your privacy.

Based on years of customer feedback and our experience, here are some details you should pay attention to when using signal jammers. Please read carefully.

1. Make sure the antenna and other accessories are installed correctly;

2. To ensure sufficient power, the handheld indicator light turns yellow or red to indicate that the power supply has been dropped, and the shielding effect is not as good as usual;

3. Ensure that the mobile base stations are more than 200 meters apart;

4. The shielding effect depends on the surrounding environment. The interference effect of mobile phones used in urban areas is better than that in cities. Because the density of mobile base stations in cities is larger and the distance between base stations is closer, the signals emitted by urban mobile base stations (where the jammer needs to be blocked) are stronger than those in urban areas. multiple times;

5. When using a jammer, there should not be any metal objects or wall obstructions around the antenna and between the jammer and the phone to block signal transmission;

6. Strong magnetic field and strong electromagnetic wave environment will affect the interference effect;

7. The installation height of the jammer should be as high as possible to the same level as the device you want to shield;

8. Long-term use of interference opportunities causes high heat and affects the interference radius;

9. When the phone is on a call, the jammer will not easily block the signal (the signal is very strong during the call);

10. The radio wave emitted by the jammer is a high-energy material. It is normal for the machine to heat up due to the collection of high-energy materials;

11. There is a certain lag in the refresh of the signal display grid on the mobile phone. You may have turned on interference but the mobile phone still shows signal status, but in fact the mobile phone cannot be used. Please refer to the actual results;

12. To test the function of the GPS jammer, please download the GPS signal detection software to test the shielding effect, or open the car navigation function test;

13. The wifi jammer device with WIFI interference function will also block other appliances with WIFI, such as wireless microphones, speakers, monitors, etc.
