​First, you need to explain to the communication jammer equipment manufacturer the location and size of the range you need to shield. The most important point is whether there are mobile phone signal towers built by operators within three to four hundred meters, which will affect the selection of the jammer. Find several, compare prices and qualifications, and choose the best.

1. Shielded frequency bands: Before purchasing, you need to know which signals you want to block. Can selectively block ordinary mobile phone signals (2G 3G 4G). If you only block 2 and 3G or only 3 and 4G, this can be adjusted before leaving the factory. However, Mohan Communications' mobile phone signal jammer uses full-band shielding. If users need to block a certain signal, they only need to install the corresponding antenna on the machine.
2. Applicable places: Regarding the use of shielding, if it is used in indoor places, it is a shielding device that is generally suitable for examination rooms, conference rooms, offices and other spaces. Gas stations need to be explosion-proof and high-temperature resistant; if it is an outdoor open area, a medium-power signal jammer needs to be used to achieve a suitable distance.
3. Appearance: The shielding cover can be divided into external antenna and internal antenna. Generally speaking, external antennas take up more space than internal antennas because they extend outward. One point; since the antenna extends outward, the effect of an external antenna is more stable.
4. Power size: Shielding devices can generally be divided into small power, medium power and high power. Power ranges from 3W to 100W. When we recommend users to choose Mohan Communications mobile phone signal jammer, it will be based on the area to be shielded.
5. Shielding range: The shielding range is proportional to the power. Generally, test rooms use more low-power signal isolators. It is enough to install one in a classroom, and the shielding range is about 200 square meters. The shielding distance can reach 300-400 meters, depending on the local field strength.  signal jammer
6. Volume: Generally speaking, the smaller ones are handheld and portable, relatively small and easy to carry; low-power desktop computers are generally not very large, similar to small notebook computers; high-power ones are relatively bulky, and the size of the tow box type is very huge.
7. Power supply: The handheld version uses a built-in lithium battery. After the mobile phone signal jammer runs out of power, you can use the power adapter to charge it; the desktop examination room uses 220V voltage supply, and the vehicle power supply is generally 12-36V voltage supply.

With the continuous development of communication technology, people's demand for outdoor signal jammers is also increasing. However, the installation of outdoor signal jammers involves a complex set of engineering issues and technical considerations.  signal jammer

1. Installation plan
Choose a suitable location: When installing an outdoor signal jammer, you first need to choose a suitable location. Generally speaking, the location should be as close as possible to the area where the signal needs to be shielded to ensure the best signal shielding effect.
Consider environmental factors: When choosing an installation location, you also need to consider surrounding environmental factors, such as buildings, trees, terrain, etc., to ensure that the signal jammer will not be blocked or interfered with, affecting its normal operation.
Determine the installation height: When installing an outdoor signal jammer, you need to determine its installation height so that it can cover the signal source that needs to be shielded. Generally speaking, the higher the installation height, the wider the coverage, but safety and stability also need to be considered.
Fixed mounting bracket: When installing the outdoor signal jammer, you need to use a special mounting bracket to fix it in the selected location. The bracket should have sufficient stability and load-bearing capacity to ensure the safety and stability of the signal jammer.
Arrange power and grounding: When installing an outdoor signal jammer, you need to consider its power and grounding issues. An appropriate power interface should be selected and wired correctly. At the same time, ensure that the signal shield is well grounded to the ground to ensure the safe operation of the equipment.

2. Precautions
Comply with regulations and standards: When installing outdoor signal jammers, you need to strictly comply with relevant regulations and standards to ensure the safety and compliance of the equipment. Especially when installing in public places or special environments, you should pay attention to comply with relevant laws and regulations.
Regular maintenance and inspection: After installation, the outdoor signal jammer needs to be maintained and inspected regularly to ensure that the equipment is in good working condition. The inspection content includes the appearance of the equipment, connection lines, power supply, etc. If any problems are found, they will be dealt with in a timely manner.

Cell phone signal jammers, as a device used to block or interfere with cell phone signals, are not only widely used in military, prison and government fields, but also play an increasingly important role in business environments. In the business world, cell phone signal jammers are widely used to maintain security, protect privacy, increase work efficiency, and improve customer experience. This article takes an in-depth look at the use of cell phone jammers in a business setting so businesses can understand how to get the most out of this technology.

 

1. Business meetings and confidential negotiations
Business meetings and confidential negotiations are common scenarios in business settings, and cell phone signal jammers can be used to maintain the confidentiality of meetings and negotiations. By blocking cell phone signals, you can prevent attendees from taking photos, recordings, or transmitting confidential information via their phones during meetings. This helps ensure that business secrets and strategic plans are not leaked, enhancing business security.

2. Hotels and conference centers
Hotels and conference centers often want to provide a quiet environment to ensure smooth running of meetings, events, weddings, etc. Cell phone jammers can be used to limit guests' cell phone use to specific areas, thereby reducing unnecessary interference. This helps improve customer satisfaction, especially for events looking for concentration and a quiet atmosphere.

 

3. Restaurants and cafes
Some restaurants and cafes want to create an environment that is social media-agnostic and focused on dining and connecting. Cell phone jammers can be used to limit guests' use of cell phones during meals, encouraging face-to-face communication and enhancing the dining experience. Additionally, it helps reduce guests taking photos and recordings inside the restaurant, maintaining the privacy and uniqueness of the restaurant.

 

Cell phone signal jammers have wide application prospects in business environments and can be used to maintain security, improve work efficiency, protect privacy, improve customer experience and respond to emergencies. However, when using a cell phone jammer, legal compliance must be carefully considered and the appropriate device selected based on specific needs. By fully understanding the application potential of cell phone jammers, businesses can better leverage this technology to improve the safety and efficiency of their business environments.
