How you can Block Cell Cell phone Calls on Your Phone
If you want to block cell phone calls from your mobile, there are several alternatives. The first is to utilize Nature as an agent for blocking. For instance, lead paint is known to block cell phone signals. Second, buildings and cars are able to hinder wireless signals. Lead paint can also be used as a blocker of WiFi signals. Finally, there are things you can do to prevent cell phone signals from coming to your home.
Nature can stop cell phone signals
In rural areas, cell phone signals are typically blocked by geography. Mountains, dense vegetation, and bad weather can all hinder cell phone signals. In these areas, cell signal providers could provide lesser coverage or may not be able to transmit completely. Fortunately, there are ways to solve the issue. To fix the problem first, you must determine what is hindering your signal.
Plaster is a common construction material that is able to block cell phone signals. Plaster is able to block radio waves by cutting down their energy. Plaster blocks cell signals by approximately 10 dB. But, this kind of material is ineffective at stopping wifi signal.
Building materials can hinder cell phone signals
A typical home is composed from a variety of materials which can block cell phone signals. Concrete, in particular, can greatly reduce the signal from a smartphone. Concrete is also extremely dense and can interfere with wifi signals. This could result in signal loss of -30dB or more, based on the location.
Wood, particularly the inside frame, may also create a problem with cell phone reception. Although softer woods won't be as harmful as hard woods, they can significantly diminish the signal. Likewise, concrete is 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 can also interfere with cell phone signals. For instance, fiberglass is not as dense as other materials and repels cellular signals. No matter what material you choose, it is crucial to use construction materials that do not interfere with the cellular signals.
Cars can block cell phone signals
Cars contain a lot of metal in them and that can block cell phone signals. There are also window coatings that block signals from cell phones. In a car, it can be a danger for drivers as well as passengers to use the phone. Some cars are designed to block signals at specific frequencies to prevent driver distraction.
Buildings can also hinder cellphone signals. Concrete and metal aren't effective conductors for RF waves and can interfere with the signal. Additionally, big buildings and parking garages can deflect radio waves. Building materials, such as glass coated with metal oxide, can hinder the signal strength of cell phones.
Lead paint blocks WiFi
Lead paint is a product that could interfere with WiFi and cell phone signals. Lead blocks the signals of these two technologies due to the fact that it is made up of aluminum and copper particles that block the signal. These particles could block signals from various technologies. Lead is not the only substance which can block cell phone and wifi signals. Aluminum foil can also function as an effective shield. This ability block signals was first discovered by Michael Faraday, in 1836.
The use of lead paint to block cell phone and wifi signals is illegal in a majority of countries. It's also considered to be a violation of federal law. According to law, it's illegal to employ the signal jammer in public areas and in homes. The majority of cell phones and wifi technology uses 2.4GHz and 5GHz frequencies. It is ,however possible to apply a special paint to block these frequencies up to 100GHz.
Fiberglass insulation may block signals from cell phones
Fiberglass insulation can be an effective way to block cell phone signals. The type of insulation used is not as dense as other materials, such as concrete and brick, however it is able to still effectively block cell signals. Fiberglass also helps keep the temperature and cold within the home, while blocking the cell signals out. Fiberglass blocks the signals by absorption of the heat and blocking the signal.
It can also block out sound traveling through drywall. Fiberglass insulation is lightweight and is easy to put in. It effectively blocks wifi and cell phone signals. It is also eco-friendly and fire-resistant.
