How do I make a cell phone jammer?

Cell Phone JammerHave you ever gotten frustrated over listening to people talk on their cell phones in theaters, public transportation, work, churches and school? Building a cell phone jammer can be a good way to stop all of this and have some fun too.

Save yourself from listening to people who just can’t stop talking for hours and hours at a time. Cell phones are radio-transmitting devices, which means that their signal has the potential to be disrupted. This article will explore how a cell phone jammer works and how to build one.

How do I Jam a Cell Phone?

The first thing that one needs to understand is that jamming cell phones is illegal. They cannot be bought legally in the United States of America. The only entity allowed to hold cell phone jammers is law enforcement.

It is also important to realize that if a cell phone jammer is ordered from overseas then it might be taken by customs officials. In a nutshell, we DO NOT ADVOCATE THE USE OF CELL PHONE JAMMERS illegally so consider this a fun overview guide to learn how to build a cell phone jammer for theoretical purposes only if you live in the United States.

Jammers can broadcast on any frequency and are effective against:

  • Integrated Digital Enhanced Network (iDEN)
  • Advanced Mobile Phone System (AMPS)
  • Nextel Systems
  • Code Division Multiple Access (CDMA)
  • Time Division Multiple Access (TDMA)
  • Global System for Mobile Communications (GSM)
  • Personal Communications Services (PCS)
  • Distributed Communications System (DCS)

The range of the jammer is determined by its local environment and its own power. The local environment may be littered with walls, hills and other objects which cause radio signal interference.

Build Your Own: Change Your Cell Phone Into a Cell Phone Jammer

It is possible to build a cell phone jammer by modifying a cell phone. Certain cell phone jammers are designed to be installed into cell phones. They can be used to stop all cell phone activity in:

  • Classrooms
  • Small seminar halls
  • Meeting rooms and board rooms
  • Private offices
  • Bus and vehicles (imagine how you can finally have a good undisturbed nap)
  • VIP and privacy-sensitive scenarios

These are also illegal and difficult to build yourself. You must have some knowledge and skill at soldering microchips and manipulating radio frequencies. You must buy this jammer online from an overseas distributor.

Build Your Own: Wave Bubble Cell Phone Jammers

A Wave Bubble Jammer has the capability of jamming all types of radio frequencies, including cell phones. A lithium-ion battery is be installed to provide power and can provide up to 2 to 4 hours of jamming.

The battery is rechargeable via a USB connector or a 4 mm DC jack. Triple A batteries can also be used. Building a Wave Bubble Jammer requires a large amount of SMT smoldering on specific chips, especially the multiple SOT, TSSOP and 0603 RC.

Two radio antennas run out of the chips and interfere with radio signals in the range of 20 to 25 feet. Amateurs should get help from person who is skilled at smoldering if they want to adequately abide by the Wave Bubble Jammer’s construction guidelines in order to construct and debug the jammer.
The total cost of a Wave Bubble Cell Phone Jammer is 25$ for printed circuit boards and 100$ for parts.

Tools needed:

  • Soldering iron
  • Solder
  • Solder Paste
  • (De)solder braid
  • Power Supply
  • Multimeter/Oscilloscope
  • Spectrum Analyzer
  • Needle-nose pliers
  • Tweezers
  • Board holder
  • Small Flashlight
  • Magnifying Glass

What Happens If You Get Caught with a Cell Phone Jammer?

Cell phone jamming is prohibited in FCC code section 15. The exact types of legal prosecution that can be used against cell phone jammer users varies between states. Selling a cell phone jammer carries hefty penalties. Before you try to build or buy a cell phone jammer, make sure that you understand the legal repercussions of using such a device.
