If you want to block phone calls made by cell phones on your phone, there are several choices. First, you can utilize Nature as an agent to block calls. For instance the lead paint has been 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. There are also options to prevent cell phone signals from coming into your home.

Nature can interfere with signals from cell phones
In rural areas, cell phone signals are usually blocked by geography. Mountainous terrain, dense vegetation and severe weather conditions can all block cell signals. In these regions the cell signal providers might offer lower coverage or even disappear completely. However, there are options to fix the problem. To resolve the issue first, you must find out what's the issue that is preventing your signal.

Plaster is a typical material used in construction that blocks the signals of cell phones. Plaster is able to block radio waves and decreasing their energy. It blocks the signals of cell phone by around 10 decibels. However, this type of material is not effective in block signals from wifi.

Building materials can hinder signals for cell phones
A typical home is made from a variety of materials which can block cellphone signals. Concrete is one of them. It could significantly cut off the signal of a smartphone. Furthermore, concrete is extremely dense, and it can block wifi signals. This could result in signal loss of -30dB or more, depending on the region.

Wood, especially the interior frame, can cause issues with reception for cell phones. While softwoods aren't as bad as harder woods however, they will significantly reduce the signal. Concrete is also used to support buildings, and while it is able to withstand massive weight, it can affect the signal.

In addition to metal and wood Other materials may also interfere with signals from cell phones. Fiberglass, for instance, is less dense than other materials, and can block cellular signals. No matter what material you choose it is important to choose building materials that don't interfere with cell signals.

Cars can stop cell signalling
Cars have a lot of metal in them and that can block cell phone signals. There are also window coatings that block cell signals. In a car, it can be a danger for drivers as well as passengers to talk on the phone. Certain cars are built to block signals at specific frequency to stop drivers from becoming distracted.

Buildings also hinder cellphone signals. Metal and concrete are not excellent conductors of RF signals, which can interfere with the signal. Also, large buildings as well as parking garages can block RF waves. Building materials, for instance, glass coated with metal oxide, can cut down the signal strength of cell phones.

Lead paint blocks wifi
Lead paint is a substance that can hinder WiFi and cellphone signals. Lead paint blocks signals from these two technologies because it contains copper and aluminum particles that can block the signal. The particles can block signals from various technologies. The lead is not the only material that can block wifi and cell phone signals. Aluminum foil also acts as shielding. Its ability to block signaling was initially discovered by Michael Faraday, in 1836.

Lead paint used to hinder wifi and cell phone signaling is prohibited in most countries. It is also considered as a violation of federal law. According to law, it is illegal to make use of the signal jammers within public areas and at home. The majority of cell phones and wifi technologies operate on 2.4GHz and frequencies of 5GHz. It is however possible to use special paint to block the frequencies to 100 GHz.

Fiberglass insulation may block cell phone signals
Fiberglass insulation can be an effective method to block cell phone signals. The type of insulation used is less dense than other materials like concrete and brick, yet it can still effectively block cell signals. Fiberglass will also help to keep warm and cold in the house, while keeping cell signal out. Fiberglass blocks signals by absorption of the heat and blocking the signal.

It also blocks sound traveling through drywall. Fiberglass insulation is blue light glasses and is easy to put in. It can effectively block cell phone and wifi signals. It is also green and fire-proof.
