If you wish to block cell phone calls on your phone, there are several alternatives. The first is to make use of Nature as a blocking agent. For example, lead paint is known to block signals from cell phones. Additionally, vehicles and buildings are able to hinder wireless signals. Lead paint is also known to block WiFi signals. In the end, there are ways to prevent mobile phone signals from getting into your home.

Nature can stop signals from cell phones
Rural areas are where signals from cell phones are often blocked by the geography. Mountains, dense vegetation and weather-related issues could all interfere with cell signal reception. In these regions mobile signal providers could provide lesser coverage or may not be able to transmit altogether. There are solutions to fix the problem. To fix the problem, you should first find out what's the issue that is preventing your signal.

Plaster is a typical building material that can block cellphone signals. Plaster absorbs radio waves and cutting down their energy. Plaster blocks cell signals by around 10 decibels. However, this type of material is ineffective at blocking wifi signals.

Building materials could block cell phone signals
A typical home is composed of a variety of materials that could hinder cellphone signals. Concrete is one of them. It could significantly cut off the signal received by smartphones. Additionally, concrete is highly dense, and it can block wifi signals. This can result in signal loss of 30dB or more, based on the area.

Wood, particularly the inside frame, may also create problems with reception for cell phones. Although softer woods won't be as bad as harder woods however, they will significantly reduce the signal. Likewise, concrete is used to support buildings, and while it is able to withstand massive weight, it can also interfere with the signal.

In addition to metal and wood, other materials can also interfere with signals from cell phones. For instance, fiberglass is less dense than other materials, and can block the signals of cell phones. Whatever the material it is essential to select building materials that do not interfere with cellular signals.

Cars are able to block cell phone signals
Cars contain a lot of metal in them and that could block signals from cell phones. There are also windows that are coated with a coating to block cell signals. In a car, it can be a unsafe place for drivers and passengers to use the phone. Certain cars are built to block signals at certain frequencies to avoid distraction by drivers.

Buildings also hinder cell phone signals. Concrete and metal are not excellent conductors of RF signals, which can interfere with the signal. Also, large buildings as well as parking garages can block the RF signals. Building materials, for instance, metal oxide-coated glass, also reduce the signal strength of cell phones.

Lead paint blocks WiFi
Paint made of lead is material that could cause interference with WiFi and cellphone signals. Lead paint blocks signals from these two technologies since it is made up of aluminum and copper particles that could hinder the signal. The particles can block signals from any technology. It isn't the only material that can block cell phone and wifi signals. Aluminum foil also acts as a shield shirts. Its ability to block these signals first was discovered by Michael Faraday in 1836.

Leaded paint is used in the use to block cell phone and wifi signals is illegal in many countries. It is also considered as a violation of federal law. According to law, it's not legal to use the signal jammers within public spaces and at home. The majority of cell phones and wifi technologies use 2.4GHz and 5GHz frequencies. However, it is possible to apply a special paint to block these frequencies as high as 100GHz.

Fiberglass insulation may block cell phone signals
Fiberglass insulation is an effective way to block signal transmissions from cell phones. The type of insulation used is lighter than other materials like concrete and brick, but it can still block cell signals. Fiberglass will also help to keep heat and cold inside the house, while keeping cell signal out. Fiberglass blocks the signals by absorbing the heat and block the signal.

It can also block sound from passing through the drywall. Fiberglass insulation is lightweight and easy to install. It is able to block wifi and cell phone signals. It is also environmentally friendly and fire-proof.
