If you wish to block cell phone calls to your cell phone there are a few alternatives. First, you can utilize Nature as an agent for blocking. For example lead paint is used to block signals from cell phones. In addition, cars and buildings can block wireless signals. Lead paint has also been known for its ability to block WiFi signals. Finally, there are options to prevent mobile phone signals from getting into your home.

Nature can stop signals for cell phones
In rural areas, cell phone signals are often blocked by the geography. The terrain is mountainous, the vegetation is dense, and bad weather can all hinder cell phone signals. In these locations the cell signal providers might offer lower coverage or even disappear completely. However, there are options to address the issue. To correct the issue first, you must find out what's the issue that is preventing your signal.

Plaster is a common material used in construction that blocks the signals of cell phones. Plaster works by absorbing radio waves, thereby reducing their energy. The material blocks signals from cell phones by approximately 10 dB. But, this kind of material is not effective in stopping wifi signal.

Building materials could hinder cell phone signals
The typical house is comprised of numerous materials that can interfere with cell phone signals. Concrete, in particular, can greatly reduce the signal received by smartphones. Concrete is also extremely dense, and it can block wifi signals. It can cause signal loss of -30dB or more, depending on the location.

Wood, specifically the interior frame, may also create problems with cell phone reception. While softwoods aren't the same as woods made of harder materials, they can significantly diminish the signal. Concrete is also used to support buildings, and while it can support enormous weight, it can also affect the signal.

Apart from metal and wood, other materials can also interfere with the signals of cell phones. Fiberglass, for example, is less dense than other materials, and can block cellular signals. No matter what material you choose, it is crucial to choose building materials that don't interfere with cellular signals.

Cars can hinder cell phone signals
Cars have a lot of metal in them and that can block cell phone signals. There are also glass coatings which block cell phone signals. Cars can be unsafe place for drivers and passengers to use the phone. Certain vehicles are designed to block signals at certain 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. Also, large buildings and parking garages can deflect the RF signals. Building materials, for instance, glass coated with metal oxide, silver underwear can reduce the signal strength of cell phones.

Lead paint blocks wifi
Paint made of lead is material which can hinder WiFi and cell phone signals. Lead paint blocks signals from these two technologies due to the fact that it has aluminum and copper particles that can hinder the signal. The particles can block signals from any technology. It isn't the only one that blocks wifi and cell phone signals. Aluminum foil also acts as an effective shield. The ability of aluminum foil to block these signals first was discovered by Michael Faraday in 1836.

Lead paint used to stop wifi and cell phone signals is illegal in a majority of countries. It's also as a violation of federal law. According to the law, it's illegal to use signals jammers inside public places and in homes. Most cell phone and wifi technology uses 2.4GHz and 5GHz frequencies. However, it is possible to use special paint to block these frequencies as high as 100 GHz.

Fiberglass insulation could block cell phone signals
Fiberglass insulation can be effective in blocking signal transmissions from cell phones. This type of insulation is less dense than other materials like concrete and brick, yet it can be effective in blocking cell phone signals. Fiberglass also helps keep the warm and cold in the home while keeping cell signals out. Fiberglass blocks signals by absorption of the heat and block the signal.

It also blocks the sound that travels 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.
