Linking connection problems to signal interference can be difficult. However, if you notice these signs, you may be the target of this attack:

Your signal is good, but you can't make a call or send a message. The receiving bar may be lower than usual, but it's not bad enough to stop all communication.

The router didn't show any problems, but it couldn't get online. Your Internet connection may appear normal even if there is signal interference.

Don't trust apps that claim to detect interference. Apps that claim to be able to spot interference are often fake and will show false results.

If you suspect interference, stay away. Most cell phone jammer operate within a limited radius. Therefore, try to leave the area that appears to be affected. If wireless communication is normal, you may fall victim to signal interference.

Call your service provider. Other root causes can cause wireless communication to fail. Therefore, consult your provider for possible causes.

What is signal interference? Is it legal?

Signal interference overwhelms the target signal frequency and prevents nearby users from sending or receiving data. All devices that transmit or receive wireless signals over a particular frequency are susceptible to interference. Thus, jamming can target Wi-Fi, Bluetooth, GPS, and radio communications.

Because of its dangerous effects, jamming is illegal in most countries. If caught using jamming device to disrupt wireless communications, offenders face hefty fines and jail time.

In theory, signal interference can help designate phone-free zones, especially in schools. However, in most cases, the use of jamming devices is illegal.

In France, a man used a multi-band wifi blocker to stop his children from accessing the Internet at night. However, attempts to limit Internet use at home extended to neighbors, causing disruption.

For the disturbance, the man faces a fine of 30,000 euros and up to six months in prison. Therefore, even seemingly harmless use of interference can land you in hot water with law enforcement agencies.

How does signal jamming work?

Signal jamming is the deliberate disruption of communications by transmitting strong signals and overwhelming frequencies. Depending on its operation, jamming is a DDoS or DoS attack that stops a wireless exchange.

Also, intentional interference is important, because unconscious interference is interference. The latter occurs when the Wi-Fi signal is weakened by nearby devices using the same frequency.

A jamming device can be a relatively small device that broadcasts a continuous signal to block other transmissions. Some high-end products can cost thousands of dollars, but there are also some inexpensive devices. The following are the main types of jamming systems:

Handheld or portable systems may affect smaller areas.

Fixed signal gps blocker can operate within a larger radius and interfere with a certain frequency range.

Homemade devices that cover a smaller area may target one or two frequencies.

Signal jamming as a means of censorship

1. Government-ordered disruptions may cause users in specific areas to lose access to the Internet. In other cases, radio broadcasts from other countries may also be unavailable due to interference systems.


2. China has taken signal jamming measures to block radio signals sent by foreign broadcasters.


3. Iran launched satellite jamming to block BBC signals during the presidential election.


4. Russia has used multifunctional devices to disrupt communications in Ukraine.

Protect yourself from signal interference

• In addition to detecting when someone is trying to interfere with your signal, there are a number of prevention methods you can consider.


• First, you can change the Wi-Fi frequency and channel. Most signal jamming devices block the 2.4 GHz frequency. So, by choosing 5 GHz, you can restore your Internet connection.


• For home security systems, you can use tools that use proprietary algorithms that can identify interference. Such programs then alert the owner that someone is trying to interfere with the security system.


• Finally, if you are unable to send a message or call, you can try using a VoIP service. This should help avoid attempts to interfere with radio frequencies.
