How to Use a Microwave Wi-Fi Jammer to Block Cell Phone Signals

A microwave wifi jammer will prevent the signal from reaching your mobile phone or tablet. There are different types of jammers, including Magnetron and Wave Bubble. Depending on the design, the jamming effect may vary. Some of them can be installed in walls, concrete walls, and metal laths. Here are some tips to buy a good jammer for your needs. Listed below are some of the best ways to block cell phone signals.

Wave Bubble

The Wave Bubble is a portable RF jammer with self-tuning capabilities. It’s the size of a pack of cigarettes and has a battery life of up to two hours for jamming two bands or four hours for single band jamming. The device is rechargeable via mini-USB connector or 4mm DC jack. It runs on three AAA batteries. This device isn’t for sale in retail stores, but you can build one yourself. However, it’s illegal in many places.

Magnetron

The Magnetron microwave wifi jammer is a high-power RF signal emitting device. It can be dangerous to your health. Moreover, you can change it into a reception device, which is capable of analyzing signals in the 1 GHz to 18 GHz frequency bands. Its remote control makes it possible to change its operation mode from a jamming device to a reception one, which is used to analyze signals. It can be stored for later analysis or sent to a superior device.

Metal laths

Concrete and plaster walls are common obstructions to Wi-Fi signal. Both plaster and concrete contain metal components and act as a Faraday cage for wireless signals. A Wi-Fi booster cannot penetrate through concrete or plaster walls, which also hinders the WiFi signal. Plaster walls are made of cement, gypsum and lime. They are usually 5/8 inches thick, and their combination greatly slows down WiFi signal.

Concrete walls

A hollow block wall can block a WiFi signal almost entirely. In addition, a concrete wall with an 8-inch thickness is unlikely to pass a signal either. A hollow block’s outer layer is about an inch thick, but it is still solid and will likely contain reinforcement. In addition, a hollow block’s rebar will help it retain its strength. If you want to use a concrete wall as a WiFi jammer, you should keep a few things in mind.

Plaster walls

A plaster wall is a common material used in buildings. While walls of other types of materials can be a good place to install a WiFi jammer, plaster walls can actually interfere with Wi-Fi signals. Plaster is made of limestone, a sedimentary rock composed of calcium carbonate (CaCO3). Plaster walls are extremely thick and act like Faraday cages. If you want to jam Wi-Fi signals, you need a device that is designed specifically for plaster walls.

Older cordless phone

Wi-Fi and cordless phones share the same 2.4Ghz frequency, but there are differences between the two. Microwaves and cordless phones emit different waves. In theory, a cordless phone jammer could disrupt one channel of a Wi-Fi network while it is “in use.” However, in practice, a cordless phone jammer would only affect a single radio frequency, and would only work on a device that is off its charging base.
