These cell phone jammers create signal interference zones within a certain range by emitting signals at specific frequencies. This technology can block the signal transmission between the device and the base station to achieve interference management in wireless communication. These jammers utilize multi-band and multi-antenna technology and can simultaneously jam a variety of wireless signals, including 2G, 3G, 4G, 5G, WLAN, GPS, etc.

The WLAN jammer protects your information security

The working principle of the WLAN jammer is to block or suppress the original radio signal by sending strong jamming signals to the target frequency band (e.g. 2.4 GHz or 5 GHz), making the target device unable to send or receive signals normally.

  • 2.4 GHz band: This is the frequency range used by most WLAN networks and Bluetooth devices today (approx. 2412 MHz-2472 MHz).
  • 5 GHz band: Newer WiFi networks are starting to use this band with a frequency range of approximately 5150 MHz to 5850 MHz. The most common signals are WiFi 5.2G (5150-5350 MHz) and WiFi 5.8G (5725-5850 MHz).

By selecting devices that interfere with either 2.4 GHz or 5 GHz, WLAN jammers can effectively jam wireless signals in these two dominant frequency bands.

A WLAN jammer is a device that has been specially developed to jam radio signals. Its main functions include the following aspects:

1. data protection
WLAN jammers prevent the theft or surveillance of data by unauthorized persons by jamming signals and thus effectively protecting privacy and company secrets.
2. interference with monitoring devices
It can interfere with surveillance devices such as Wi-Fi cameras that rely on Wi-Fi or Bluetooth signals to prevent unauthorized surveillance.
3. protection of medical devices
In medical environments, WLAN jammers can protect the safety of medical equipment by preventing wireless signals from interfering with the normal operation of the equipment.
4. control of the educational scene
During exams or training sessions, Wi-Fi jammers can interfere with students' internet access, preventing cheating during exams and increasing administrative transparency at the same time.
5. protect yourself from competitors
In a business environment, WLAN jammers can prevent competitors from stealing data via wireless technology and ensure information security.

GPS jammer to prevent strangers from tracking you

GPS jammers block and interfere with satellite signals by emitting jamming signals in certain frequency bands so that receiving devices cannot decode location data correctly. Here are the key points on how it works:

1. target frequency: GPS signals mainly cover the frequency bands L1 (1575.42 MHz) and L2 (1227.6 MHz). Advanced models can also interfere with L3, L4 and L5.
2. broad interference: the signal emitted by the jammer interferes with all devices within a certain range instead of targeting a specific device, so it can affect other GPS devices in the same range.

Application scenarios for GPS jammers

1. protection of privacy
(a.) Prevent vehicle GPS tracking devices from uploading the user's location.
(b.) Interference with the smartphone's GPS module to prevent location leaks.

2. company and vehicle management
(a.) Some companies use GPS jammers when testing the interference suppression capability of their devices.
(b.) Protect logistics vehicles and prevent adversaries from tracking cargo transportation routes via GPS.

A GPS jammer is a device that can protect privacy and prevent location tracking. It is often used by private individuals, companies and in special scenarios.

What should you consider before buying a jammer?

Do you choose a portable or desktop model?

Portable jammer

A portable jammer is a small device that interferes with or blocks communication between a cell phone and a cell tower by emitting the same radio frequency signals as a cell phone. This device effectively prevents a cell phone from receiving or transmitting signals, rendering it unusable within the range of the jammer. Portable jammers are often used in scenarios where temporary or covert signal jamming is required.

This type of portable jammer is small, lightweight and easy to carry, is usually about the same size as a smartphone or small router and can even be hidden when in use. The portable jammer is powered by rechargeable batteries and does not require a power connection to operate. Some models are designed so that they can be plugged directly into the cigarette lighter or car socket. Operation is very simple and usually requires only one button to start. Some customized models also allow users to select specific interference frequencies to avoid interfering with other signals.

Portable jammers support a variety of jamming frequencies, including cellular networks, Wi-Fi, GPS, radio signals, and some models even support interference with 5G signals. Because the devices are small and battery-powered, their jamming range is typically limited, typically between 5 and 20 meters, depending on device power and surrounding environmental factors. With some devices, users can adjust the output power to meet the requirements of different scenarios and flexibly adjust the interference range.

Which environment requires a desktop jammer?

Desktop jammer

The desktop jammer is a fixed signal shielding device with high signal power that can block communication signals within a certain range. Compared to portable jammers, desktop jammers are larger, more powerful and have a larger effective range. They typically cover a range of 10 to 100 meters, depending on the power of the device and the environment in which it is used. It is mainly suitable for fixed locations such as offices, conference rooms, VIP security areas, etc.

Desktop jammers are usually designed to be placed on a desktop or installed in a fixed location. They do not require frequent recharging, can be operated around the clock and therefore rely on AC power. Devices are often equipped with large coolers or fans to prevent overheating or device failure due to prolonged operation. It has wide frequency coverage and can block multiple frequency bands simultaneously, including GSM, CDMA, 3G, 4G and 5G cellular networks, as well as Wi-Fi (2.4 GHz and 5 GHz), Bluetooth, radio frequency (VHF/UHF), etc .

The desktop jammer has powerful functions, a considerable shielding effect and a high output power. The power, interference radius and shielding frequency band of the device can be adjusted as required. Due to their superior performance, desktop jammers are relatively expensive and require a stable power supply to ensure continuous operation.
