How Does a WiFi Jammer Work?
You may wonder how a WiFi jammer works. Well, it interferes with the radio frequency used by spy gadgets such as night vision cameras and motion detection systems. It also disables the Wi-Fi network, making it impossible for unauthorized people to use it. The following section will explain how a WiFi jammer works and what you can use it for. Let’s look at a few of its more common applications.
Signal jammer interferes with radio frequency used by spy gadgets
Using a signal jammer to block spy gadgets signals is illegal and is often the result of pranks or a desire to get the information of another person. Jamming is considered a criminal act and may result in jail time. The Federal Communications Commission (FCC) has strict laws about signal jamming, including sections 301 and 302(b).
A signal jammer works by imitating the signal of a targeted device. Many gadgets rely on different radio frequencies. Cell phones use frequencies that are between 890-915MHz, while pacemakers operate in the range of 402-405MHz. If one of these signals is jammed, the device will fail to work. If a signal is lost, the device will try to connect to other signals.
It interferes with motion detection and night vision cameras
The most obvious way a WiFi jammer interferes with motion detection and security cameras is by affecting the cameras’ WiFi signal. This can be done by blocking the signal with a jamming device. The jamming device can also be installed outdoors. You can also test the connectivity of the cameras by viewing the live feed. While this is not always effective, it is a viable option in most situations.
The jamming of security cameras with Wi-Fi signal is illegal and should not be attempted by a layperson. While it isn’t common in home invasion crimes, it can cause damage to sophisticated night vision cameras and motion detection systems. In addition to limiting the signal of security cameras, jamming can affect cell phone and wi-fi communications as well. This makes it impossible to track down someone in case of an emergency.
It disrupts Wi-Fi network
You have probably heard that active Christmas decorations can interfere with the signal of a Wi-Fi network. In fact, recent UK reports attribute this phenomenon to shoddy electrical design by manufacturers of fairy lights. Perhaps the makers of wireless routers are somehow guilty of colluding with the industry to block signal interference. But this is far from the only reason why active Christmas decorations disrupt Wi-Fi signals. Other possible reasons include neighboring networks, hardware malfunctions, and even RADAR activities.
Home construction and materials can also disrupt your Wi-Fi signal. Some construction materials such as thick walls or metallic mesh inside plaster walls can reduce or even block the signal. Whenever possible, move your routers to avoid these structures. If you can’t avoid them, move the repeaters. Other sources of interference include power lines and power stations. Make sure that your network is free of wires and cables that disrupt the network.
It is difficult to detect
The problem is that it is not always easy to detect a wifi jammer. The jammer is either inside a network’s central node or between nodes. In either case, it will interfere with the network. If you can detect the jammer, you can take corrective measures to minimize its impact. Here are some guidelines to help you detect a jammer. However, this article will not cover all the possible mitigations.
Detection is based on the difference between the baseline power of the jammer and the actual transmission power. This is determined by varying the distance between the jammer and the access point. The baseline power of the jammer will reduce from -35 to -32 dB for a two-meter distance. Detection threshold g has to be carefully selected because the distance changes. The next step is to determine the detection threshold.
