How to Block Cell Telephone Calls in your Phone
If you want to block calls from cell phones to your cell phone there are a few choices. You can first use Nature as an agent for blocking. For instance, lead paint is known to block signals from cell phones. In addition, cars and buildings could block wireless signals. Lead paint is also known as a blocker of WiFi signals. In the end, there are ways to prevent cell phone signals from coming into your home.
Nature can block signals for cell phones
Rural areas are where signals from cell phones 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 regions mobile phone signal providers may offer lower coverage or even disappear completely. There are solutions to solve the issue. To correct the issue, you should first identify the issue that is blocking your signal.
Plaster is a popular material used in construction that blocks cell phone signals. Plaster is able to block radio waves and reducing their energy. The material blocks signals from cell phones by about 10 dB. However, this type of material is not effective in stopping wifi signal.
Building materials could hinder 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 can significantly reduce the signal received by smartphones. Furthermore, concrete is extremely dense and may interfere with wifi signals. This can result in signal loss of 30dB or more, depending on the region.
Wood, especially the interior frame, can also cause a problem in cell phone reception. Although softer woods won't be as harmful as hard woods however, they will significantly reduce the signal. Concrete is also utilized to support buildings and while it is able to withstand massive weight, it can also affect the signal.
Apart from metal and wood Other materials may 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 important to use construction materials that do not interfere with cellular signals.
Cars are able to block cell signalling
Cars contain a lot of metal in them. This could block signals from cell phones. There are also some windows that are coated with a coating to block signals from cell phones. Cars can be unsafe place for drivers and passengers to use the phone. Certain vehicles are designed to block calls at specific frequencies to prevent driver distraction.
The construction of buildings can hinder cell phone signals. Concrete and metal are not good conductors of RF waves, which can interfere with the signal. Furthermore, large structures and parking garages can deflect the RF signals. 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 material that could interfere with WiFi and cell phone signals. Lead paint blocks signals from these two technologies since it is made up of aluminum and copper particles that can interfere with the signal. The particles can hinder the signal of various technologies. The lead is not the only one that can block wifi and cell phone signals. Aluminum foil also functions as a shield. This ability block 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 is also considered a violation under federal law. According to law, it's illegal to employ the signal jammers within public areas as well as in private homes. The majority of cell phones and wifi technologies operate on 2.4GHz and frequencies of 5GHz. It is however possible to apply a special paint to block these frequencies up to 100GHz.
Fiberglass insulation can block cell signalling from cell phones
Fiberglass insulation is an effective method to block cell phone signals. This type of insulation is lighter than other materials like concrete and brick, however it is able to still block cell signals. Fiberglass also helps keep the warm and cold in the home while keeping cell signal out. Fiberglass blocks signals by absorbing heat and block the signal.
It can also block sound from passing through the drywall. Fiberglass insulation is light and easy to install. It is able to block cell phone and wifi signals. It is also environmentally friendly and fire resistant.
