How to Block Cell Mobile phone Calls in your Phone
If you want to block phone calls made by cell phones to your cell phone there are several options. First, you can utilize Nature as an agent for blocking. For example, lead paint is known to block signals from cell phones. In addition, cars and buildings are able to block wireless signals. Lead paint is also known for its ability to block WiFi signals. Finally, there are options to block the signals of cell phones from coming to your home.

Nature can stop cell phone signals
For rural locations, signals from cell phones are typically blocked by geographical terrain. Mountainous terrain, dense vegetation and weather-related issues can all hinder cell phone signals. In these locations the cell signal providers could provide less coverage or signal disappear altogether. Fortunately, there are ways to address the issue. To correct the issue it is first necessary to find out what's blocking your signal.


Plaster is a common building material that is able to block cellphone signals. Plaster absorbs radio waves, thereby decreasing their energy. Plaster blocks cell signals by about 10 dB. But, this kind of material isn't effective at block signals from wifi.

Building materials could block cell phone signals
A typical home is made from a variety of materials which can hinder the signals of cell phones. Concrete is one of them. It can significantly reduce the signal received by smartphones. Concrete is also extremely dense, and it can block wifi signals. It can cause signals being lost by -30dB or more, depending on the region.

Wood, especially the interior frame, can cause a problem with cell phone reception. Although softer woods won't be as bad as harder woods, they can significantly diminish the signal. Concrete is also utilized to support buildings and while it can support tremendous weight, it will also interfere with the signal.

Besides wood and metal and other metals, other materials may interfere with signals from cell phones. For instance, fiberglass is less dense than other materials, and can block cellular signals. No matter what material you choose, it is crucial to select construction materials that do not interfere with cellular signals.

Cars are able to stop cell phone signals
Cars contain a lot of metal in them. This can block cell phone signals. There are also glass coatings which block signals from cell phones. In a car, it can be a unsafe place for drivers and passengers to use the phone. Certain vehicles are designed to block signals at specific frequency to stop drivers from becoming distracted.

Buildings can also hinder cellphone signals. Concrete and metal are not excellent conductors of RF signals, which can interfere with the signal. Additionally, big buildings and parking garages can deflect RF waves. Building materials, for instance, glass coated with metal oxide, can reduce the signal strength of cell phones.

Lead paint blocks wifi
Lead paint is a product that can hinder WiFi and cell phone signals. Lead paint blocks signals from these two technologies due to the fact that it is made up of aluminum and copper particles that can hinder the signal. radiation blocker for cell phone could block signals from all kinds of technologies. Lead is not the only one that can block wifi and cell phone signals. Aluminum foil can also function as an effective shield. This ability block signals first was discovered by Michael Faraday in 1836.

The use of lead paint to stop wifi and cell phone signals is not legal in a majority of countries. It's also a violation under federal law. According to law, it's not legal to employ signal jammers in public places and at home. The majority of cell phones and wifi technologies operate on 2.4GHz and 5GHz frequencies. It is however possible to apply a special paint to block the frequencies to 100 GHz.

Fiberglass insulation can block cell phone signals
Fiberglass insulation is an effective way to block cell phone signals. The type of insulation used is lighter than other materials such as concrete or brick, yet it can still effectively block cell signals. Fiberglass also helps keep the warm and cold in the home while keeping cell signal out. Fiberglass blocks the signals by absorbing the heat and block the signal.

It can also block sound traveling through drywall. Fiberglass insulation is light-weight and easy to install. It can effectively block wifi and cell phone signals. It is also eco-friendly and fire-resistant.
