How to Block Cell Mobile phone Calls in your Phone
If you want to block cell phone calls from your mobile, you have a few alternatives. You can first make use of Nature as an agent to block calls. For example lead paint is used to block cell phone signals. Second, buildings and cars are able to hinder wireless signals. Lead paint is also known as a blocker of WiFi signals. There are also ways to prevent mobile phone signals from getting into your home.

Nature can stop cell phone signals
For rural locations, signals from cell phones are typically blocked by terrain. Mountains, dense vegetation, and bad weather can all block cell signals. In these areas, cell phone signal providers may offer less coverage or signal disappear completely. However, there are options to fix the problem. To fix the problem it is first necessary to find out what's the issue that is preventing your signal.

Plaster is a popular building material that is able to block cellphone signals. Plaster works by absorbing radio waves and reducing their energy. Plaster blocks cell signals by about 10 dB. But, this kind of material is not effective in blocking wifi signals.

Building materials can block cell phone signals
A typical home is made of numerous materials that can block cell phone signals. Concrete is one of them. It can significantly reduce the signal received by smartphones. Furthermore, concrete is extremely dense and can interfere with wifi signals. It can cause signals being lost by -30dB or more, based on the region.


Wood, especially the interior frame, may also create issues in cell phone reception. Although softer woods won't be the same as woods made of harder materials, they can significantly diminish the signal. Concrete is also utilized to support buildings and while it is able to withstand massive weight, it can also interfere with the signal.

Apart from metal and wood, other materials can also interfere with the signals of cell phones. Fiberglass, for instance, is not as dense as other materials, and can block cellular signals. No matter what material you choose, it is crucial to choose building materials that do not interfere with cellular signals.

Cars can block cell signalling
Cars have a lot of metal in them. This could block signals from cell phones. There are also window coatings that block cell signals. Cars can be danger for drivers as well as passengers to talk on the phone. Certain vehicles are designed to block signals at certain frequency to stop drivers from becoming distracted.

Buildings also hinder cellphone signals. Concrete and metal aren't excellent conductors of RF signals and can interfere with the signal. Also, anti emf clothing and parking garages can deflect RF waves. Building materials, for instance, glass coated with metal oxide, can reduce cell phone signals.

Lead paint blocks wifi
Lead paint is a material that could cause interference with WiFi and cellphone signals. Lead paint blocks signals from these two technologies due to the fact that it contains copper and aluminum particles that block the signal. Those particles can interfere with the signals of any technology. Lead is not the only substance which can block cell phone and wifi signals. Aluminum foil also functions as a shield. Its ability to block signals was first discovered by Michael Faraday, in 1836.

Lead paint used to stop wifi and cell phone signals is illegal in most countries. It's also a violation the federal laws. According to law, it's illegal to use the signal jammers within public spaces and in homes. The majority of wireless and cell phone 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 may block cell signalling from cell phones
Fiberglass insulation can be an effective way to block signal transmissions from cell phones. This type of insulation is not as dense as other materials such as concrete or brick, however it is able to still block cell signals. Fiberglass also helps keep the warm and cold in the house while keeping the cell signal out. Fiberglass blocks signals by absorbing heat and blocking the signal.

It also blocks the sound that travels through drywall. Fiberglass insulation is lightweight and simple to install. It can effectively block cell phone and wifi signals. It is also green and fire resistant.
