Best WiFi Jammers & Bluetooth Jammers For Sale

WiFi signal jammer, also known as WiFi blocker, is a signal jamming device that sends out waves of radio energy in unison at a specific frequency to disrupt the WiFi network. Our WiFi jammers are able to block the wireless network at 2.4GHz and 5GHz so you are completely safe from cybercrimes. The 5GHz WiFi jammer can also block bluetooth as they are running on the same frequency.

Protect Your Privacy with WiFi Jammers – The Ultimate Defense Against Unwanted Signals

Are you tired of unwanted Wi-Fi signals invading your space and compromising your privacy? Our WiFi jammers are the ultimate solution for keeping your personal information safe and secure. With our cutting-edge technology, you can take control of your own Wi-Fi environment and enjoy uninterrupted privacy like never before.

What is WiFi Jammer

WiFi jammers are innovative devices designed to enhance your privacy and security by blocking or disrupting WiFi signals within a specific jamming range. They work by emitting radio waves on the same frequency as WiFi signals, effectively jamming or overpowering them, making it impossible for device like your cell phone to connect to the WiFi network. This makes WiFi signal jammer the ultimate defense against unwanted signals and unauthorized access to your network.

What is Inside Your WiFi Jammers?

Below are the main components you can find on a wifi jammer:

  • RF (radio frequency) generator
  • Signal amplification
  • Transmission
  • Antennas
  • Power supply
  • Cooling fans


Wifi jammers contain radio transmitters that generate strong radio waves matching common wireless frequencies. For instance, a jammer targeting WiFi networks would produce signals on frequency bands like 2400 MHz or 5500 MHz. The transmitters can blast interference on a single frequency or multiple bands concurrently.

The radio noise generated by the RF generator is amplified to high power levels before being broadcast out through antennas. This allows the jamming waves to spread widely and override weaker legitimate signals. With the wireless spectrum clogged by the jammer, nearby phones and routers get blocked. They can’t maintain connections to cell towers or Wi-Fi access points through the electronic fog.

That are the core components of a wifi jammer, it also contain power supply and cooling fans to make sure they operate reliably and consistently.

Who Should Use WiFi Signal Jammer?

Our main clients are research teams in universities, security consultant firms, the military, etc. Our WiFi jammers are perfect for those who need to control and restrict wireless communications in sensitive areas or situations. Our jamming devices allow authorized personnel to quickly disable WiFi and other wireless signals when necessary, such as for security purposes, wireless vulnerability assessments, or wireless protocol research and testing. With powerful jamming capability and flexible frequency targeting, our jammers give users precise control over local wireless environments. Whether you need to block wireless eavesdropping, stop remote detonation of bombs, or create a sterile testing space, our jammers can help approved consumers safely and temporarily disable wireless connectivity.

Can WiFi jammers Block Cameras?

It depends. If the camera relies upon a wireless network to function, WiFi jammers can disrupt the camera by blocking the wireless network. However, WiFi blockers are not able to interfere with wired cameras.

Jam Bluetooth Signal with WiFi Jammer?

Yes, jamming Bluetooth-enable devices with WiFi signal jammer is possible because WiFi and Bluetooth both operate on the same frequency band, 2.4GHz, which is an unlicensed frequency spectrum used for wireless communication. When a WiFi jammer is activated, it can also inadvertently interfere with Bluetooth signals.

Which is the Best WiFi Jammer?

The JM024 is one of our best-selling portable WiFi blockers, offering extensive jamming capability in a compact form factor. JM024 contains 16 antennas to provide up to 20 meters of coverage for disabling 2.4GHz and 5GHz WiFi networks. Beyond WiFi, the JM024 can also jam cellular signals, including 2G, 3G, and 4G bands. An additional feature allows blocking GPS signals when required. It comes with a DIP switches so you can selectively turn on or off jamming for various frequency bands.

What is the Range of Your WiFi Jammer?

A WiFi jammer’s range or coverage tells you how far away it can block WiFi signals. The range is the maximum distance the jammer can reach to disrupt WiFi networks. Below are the common range of our wifi jammer:

  • 5 meters
  • 20 meters
  • 30 meters
  • 40 meters
  • 100 meters


But please keep in mind that in open spaces with line-of-sight, our wifi signal blockers can affect a larger range. But walls, floors, metal objects and other barriers will limit the jamming radius. Knowing the range helps choose a wifi jammer over your desired area. A long-range jammer isn’t needed for a small room. But for an auditorium, you may need extended coverage. Check the range specs to ensure the jammer will block WiFi where you want without going too far.

Which is The Smallest WiFi Signal Jammer?

JM025 is our smallest wifi jammer, at just 122 x 78 x 27mm in size. This small pocket wifi jammer comes with a hidden antenna design and a 5 meters of blocking range. A 2000mAh battery inside delivers up to 2 hours of continuous jamming.

Which is The Most Powerful WiFi Jammer?

JM026 is our most powerful wifi jammer. The output power is about 24 – 30W, so the blocking range can up to 100 meters. It’s perfect to be used in large space area.

Which Type of WiFi Jammer Do I Need?

Buying a WiFi jammer requires some planning to ensure you get the right model for your needs. Here are some key questions to ask yourself:

Portable or Desktop Jammer?

Portable wifi jammers are small, battery-powered devices perfect for mobile use. Desktop jammers have more power but must be plugged into an outlet.

What Range Do You Need?

Consider the size of the area you need to block WiFi signals over. Shorter range jammers (5-20 meters) are suitable for singular and small rooms. For larger areas, choose a powerful long-range jammer (up to 100 meters).

2.4GHz or Dual Band Jamming?

Most WiFi runs on 2.4GHz, but 5GHz networks are also common now. Dual band wireless jammers will block both frequencies, while 2.4GHz-only models are cheaper.

Which is Your Cheapest WiFi Jammer?
