How you can Block Cell Phone Calls on your own Phone
If you wish to block phone calls made by cell phones from your mobile, you have a few choices. The first is to use Nature as a blocking agent. For example, lead paint is known to block cell phone signals. Additionally, vehicles and buildings can block wireless signals. Lead paint has also been known for its ability to block WiFi signals. In the end, there are ways to stop the signals of cell phones from coming into your home.

Nature can block cell phone signals
For rural locations, signals from cell phones are often blocked by the terrain. Mountains, dense vegetation, and bad weather can all hinder cell phone signals. In these locations, cell signal providers could provide lesser coverage or may not be able to transmit altogether. Fortunately, there are ways to fix the problem. To correct the issue, you should first determine what is hindering your signal.

Plaster is a popular building material that can block cell phone signals. Plaster absorbs radio waves and reducing their energy. It blocks the signals of cell phone by around 10 dB. However, this type of material is not effective in stopping wifi signal.

Building materials could hinder cell phone signals
A typical home is composed of numerous materials that can hinder the signals of cell phones. Concrete is one of them. It can greatly reduce the signal from a smartphone. Additionally, concrete is highly dense and may interfere with wifi signals. This can result in signal loss of -30dB or more, based on the area.

Wood, specifically the interior frame, can also cause problems with cell phone reception. Although softer woods won't be as bad as harder woods but they could significantly decrease the signal. Concrete is also used to support structures, and while it can support enormous weight, it will affect the signal.

Apart from metal and wood Other materials may also interfere with the signals of cell phones. For instance, fiberglass is not as dense as other materials, and can block cellular signals. Regardless of the material it is important to select construction materials that do not interfere with cell signals.

Cars can hinder cell signalling
Cars contain a lot of metal in them and that could block signals from cell phones. There are also some glass coatings which block cell signals. In a car, it can be a dangerous place for drivers and passengers to use the phone. Some cars are designed to block signals at certain frequency to stop drivers from becoming distracted.

The construction of buildings can hinder cell phone signals. Metal and concrete are not effective conductors for RF waves, which can interfere with the signal. Furthermore, large structures and parking garages can deflect radio waves. Building materials, for instance, glass coated with metal oxide, can hinder signals from cell phones.

Lead paint blocks WiFi
The lead paint can be a product that could interfere with WiFi and cell phone signals. Lead blocks the signals of these two technologies because it has aluminum and copper particles that block the signal. The particles can interfere with the signals of all kinds of technologies. It isn't the only one that blocks cell phone and wifi signals. Aluminum foil can also function as an effective shield. The ability of aluminum foil to block signals first was discovered by Michael Faraday, in 1836.


Leaded paint is used in the use to stop wifi and cell phone signals is prohibited in many countries. It's also a violation of federal law. According to law, it's illegal to employ the signal jammer in public places as well as in private homes. Most cell phone and wifi technologies operate on 2.4GHz as well as 5GHz frequency. Proteck'd Clothing is ,however possible to apply a special paint to block these frequencies as high as 100GHz.

Fiberglass insulation may block signals for cell phones.
Fiberglass insulation is effective at blocking cell phone signals. It is not as dense as other materials such as concrete or brick, however it is able to still block cell phone signals. Fiberglass will also help to keep warm and cold in the home while keeping cell signal from getting out. Fiberglass blocks signals by absorbing heat and block the signal.

It can also block sound that travels through drywall. Fiberglass insulation is lightweight and easy to install. It is able to block wifi and cell phone signals. It is also green and resistant to fire.
