What is Wireless Signal Jamming?

Wireless signal jamming is the act of using a radio or other device to disrupt the communications between devices on a network. This can be done for a variety of reasons, from security to privacy to state censorship or cyberattacks.

Historically, wireless jamming was most commonly used to disrupt military radio transmissions. During World War II, Nazis used signal jammers to block Allied radio stations in Europe while the Soviet Union and most of its Eastern Bloc allies jammed the United States' own broadcasts.

Today, jamming is also a threat to the public's safety as it can prevent cell phone and other personal communication services from functioning properly, interfere with police radar, and prevent GPS satellite signals from accurately tracking the location of an individual. The government has enacted legislation to protect emergency services and day-to-day communications from jamming devices. Get more info on wireless signal jamming here.

Jamming Equipment

A jammer is a type of interference generator that can disrupt wireless signals by emitting noise, tones, or pulses. Depending on the frequency range and power, jammers can affect many different types of signals, including cellular, Wi-Fi, Bluetooth, and GPS.

There are two main types of jammers: portable and stationary. The former are relatively cheap and disrupt communications on specific frequencies, while the latter are more expensive, energy-demanding, and affect a larger area.

Portable jammers are typically hand-held devices that disrupt a specific wireless connection within a small radius. These can be purchased or made from scratch.

Stationary jammers are more powerful and can effectively disrupt a broad range of signals, including those of drones. These are usually more expensive and require power supplies and forced cooling.

Jamming is an illegal activity in most countries, but there are ways to avoid being caught. For starters, consider a specialized wireless intrusion prevention system (WIPS) that can detect and prevent jamming attacks on your network.

You can also use tools like KisMac or iStumbler on an Apple device or NetStumbler on a PC to find out which channels your neighbor is using, and change their access point's channel to something more compatible with your network. This can help reduce any interference from the neighbor's network and improve your experience with wireless technology.

If you're unsure about whether you're violating any laws, contact your local law enforcement agency. They can help you determine if the jamming is legal and give you a list of possible punishments.

Do I Have to Stop Jamming?

If your neighbor is using a jammer in your neighborhood, it's important to note that it's against the law to do so. You could face a fine and jail time if you're caught. If you have a jamming device, however, it's best to keep it out of your home or office and try another method to prevent interference.

Changing the WiFi Frequency

In order to avoid being caught, you need to change your WiFi frequency to a different band. This will help you avoid the 2.4GHz frequency that most portable jammers disrupt. You can do this by logging into your router's admin dashboard and selecting the "Wireless Settings" option.
