Tips on how to Block Cell Cell phone Calls in your Phone
If you'd like to block cell phone calls on your phone, you have several choices. The first is to use Nature as a blocking agent. For cell phone radiation protector has been known to block signals from cell phones. Second, buildings and cars can hinder wireless signals. Lead paint has also been known as a blocker of WiFi signals. There are also options to stop cell phone signals from coming to your home.

Nature can stop signals for cell phones
For rural locations, cell phone signals are typically blocked by geography. Mountainous terrain, dense vegetation, and bad weather can all hinder cell phone signals. In these regions, cell signal providers could provide lesser coverage or may not be able to transmit completely. However, there are options to fix the problem. To correct the issue it is first necessary to find out what's blocking your signal.


Plaster is a common building material that can block cell phone signals. Plaster is able to block radio waves and reducing their energy. It blocks the signals of cell phone by approximately 10 decibels. However, this type of material is ineffective at blocking wifi signals.

Building materials could block signals for cell phones
A typical home is composed of numerous materials that can hinder the signals of cell phones. Concrete is one of them. It could significantly cut off the signal received by smartphones. Concrete is also extremely dense and may interfere with wifi signals. It can cause signals being lost by -30dB or more, depending on the region.

Wood, specifically the interior frame, can also cause issues with reception for cell phones. Although softwoods won't be as bad as harder woods however, they will significantly reduce the signal. Concrete is also used to support structures, and while it can withstand tremendous weight, it will also affect the signal.

In addition to metal and wood, other materials can also interfere with signals from cell phones. For instance, fiberglass is more brittle than other materials and repels the signals of cell phones. Regardless of the material it is important to choose construction materials that do not interfere with cell signals.

Cars are able to hinder cell signalling
Cars are stuffed with metal in them. This can block cell phone signals. There are also windows that are coated with a coating to block cell phone signals. Cars can be dangerous place for drivers and passengers to use the phone. Some cars are designed to block signals at specific frequency to stop drivers from becoming distracted.

The construction of buildings can block cellphone signals. Concrete and metal are not effective conductors for RF waves, which can interfere with the signal. Also, large buildings and parking garages can deflect the RF signals. Building materials, like glass coated with metal oxide, can cut down cell phone signals.

Lead paint blocks WiFi
Lead paint is a product that can interfere with WiFi and cell phone signals. Lead blocks the signals of these two technologies because it contains copper and aluminum particles that could block the signal. These particles could block signals from any technology. Lead is not the only material that blocks wifi and cell phone signals. Aluminum foil also functions as an effective shield. The ability of aluminum foil to block signals was first discovered by Michael Faraday in 1836.

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

Fiberglass insulation could block cell phone signals
Fiberglass insulation is an effective way to block cellphone signals. It is lighter than other materials such as concrete or brick, but it can still block cell signals. Fiberglass can also help keep temperature and cold within the house, while keeping cell signal from getting out. Fiberglass blocks the signals by absorbing the heat and blocking the signal.

It can also block sound from passing through the drywall. Fiberglass insulation is light and is easy to put in. It effectively blocks cell phone and wifi signals. It is also green and fire resistant.
