The way to Block Cell Mobile phone Calls on Your Phone
If you'd like to block phone calls made by cell phones on your phone, you have a few alternatives. The first is to use Nature as a blocking agent. For instance, lead paint is known to block signals from cell phones. Second, buildings and cars can block wireless signals. Lead paint has also been known to block WiFi signals. There are also ways to prevent cell phone signals from coming to your home.
Nature can block cell phone signals
In rural areas, cell phone signals are usually blocked by terrain. Mountainous terrain, dense vegetation and weather-related issues can all block cell signals. In these locations the cell signal providers could provide lesser coverage or may not be able to transmit completely. However, there are options to solve the issue. To fix the problem it is first necessary to determine what is blocking your signal.
Plaster is a typical building material that is able to block cell phone signals. Plaster works by absorbing radio waves by decreasing their energy. It blocks the signals of cell phone by around 10 decibels. But, this kind of material is ineffective at stopping wifi signal.
Building materials could hinder signals for cell phones
A typical home is composed from a variety of materials which can hinder the signals of cell phones. Concrete is one of them. It can significantly reduce the signal received by smartphones. Concrete is also extremely dense, and it can block wifi signals. This could result in signal loss of -30dB or more, based on the location.
Wood, specifically the interior frame, can cause problems in cell phone reception. While softwoods aren't the same as woods made of harder materials, they can significantly diminish the signal. Concrete is also used to support buildings, and while it is able to withstand tremendous weight, it will affect the signal.
Apart from metal and wood Other materials may also interfere with the signals of cell phones. Fiberglass, for instance, is not as dense as other materials and blocks cellular signals. Whatever the material it is important to choose building materials that do not interfere with cell signals.
Cars are able to hinder cell phone signals
Cars contain a lot of metals in them, and this can block cell phone signals. There are also windows that are coated with a coating to block cell signals. Cars can be danger for drivers as well as passengers to use the phone. Certain cars are built to block signals at certain frequencies to avoid distraction by drivers.
The construction of buildings can hinder signal transmissions from cell phones. Concrete and metal are not effective conductors for RF waves that can block the signal. Also, large buildings as well as parking garages can block RF waves. Building materials, like metal oxide-coated glass reduce cell phone signals.
Lead paint blocks WiFi
The lead paint can be a product which can hinder WiFi and cellphone signals. Lead blocks the signals of these two technologies due to the fact that it is made up of aluminum and copper particles that interfere with the signal. These particles could hinder the signal of any technology. Lead is not the only one that blocks wifi and cell phone signals. Aluminum foil also acts as a shield. The ability of aluminum foil to block these signals was first 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 an infraction of federal law. According to the law, it's illegal to make use of the signal jammers within public areas and in homes. The majority of cell phones and wifi technologies operate on 2.4GHz and 5GHz frequencies. However, it is possible to apply a special paint to block these frequencies up to 100 GHz.
Fiberglass insulation can 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 such as concrete or brick, but it can still block cell signals. Fiberglass can also help keep warm and cold in the home while keeping cell signal from getting out. Fiberglass blocks the signals by absorbing heat and blocking the signal.
It can also block sound from passing through the drywall. Fiberglass insulation is light and simple to install. It effectively blocks cell phone and wifi signals. It is also green and fire resistant.
