How you can Block Cell Mobile phone Calls in your Phone
If you'd like to block calls from cell phones to your cell phone you have several alternatives. First, you can utilize Nature as an agent to block calls. For example lead paint is used to block cell phone signals. Additionally, vehicles and buildings could block wireless signals. Lead paint has also been known for its ability to block WiFi signals. In the end, there are things you can do to block mobile phone signals from getting into your home.
Nature can interfere with signals from cell phones
For rural locations, signals from cell phones are usually blocked by geographical terrain. Mountainous terrain, dense vegetation, and bad weather could all interfere with cell signal reception. In these locations the cell phone signal providers may offer less coverage or signal disappear altogether. However, there are options to fix the problem. To correct the issue first, you must find out what's blocking your signal.
Plaster is a typical material used in construction that blocks cellphone signals. Plaster absorbs radio waves and decreasing their energy. The material blocks signals from cell phones by around 10 dB. However, this type of material is not effective in blocking wifi signals.
Building materials could hinder cell phone signals
A typical home is made of a variety of materials that could interfere with cell phone signals. Concrete is one of them. It could significantly cut off the signal of a smartphone. Concrete is also extremely dense, and it can block wifi signals. This can result in signals being lost by -30dB or more, based on the area.
Wood, specifically the interior frame, may also create issues with reception for cell phones. Although softer woods won't be as bad as harder woods, they can significantly diminish the signal. Likewise, concrete is used to support buildings, and while it can withstand tremendous weight, it will also interfere with the signal.
Besides wood and metal, other materials can also interfere with the signals of cell phones. Fiberglass, for example, is more brittle than other materials, and can block the signals of cell phones. No matter what material you choose it is important to choose building materials that do not interfere with cell signals.
Cars can block cell phone signals
Cars have a lot of metals in them, and this can block cell phone signals. There are also glass coatings which block cell signals. Cars can be unsafe place for drivers and passengers to use the phone. Certain cars are built to block signals at specific frequencies to avoid distraction by drivers.
Buildings also block cellphone signals. Concrete and metal aren't good conductors of RF waves, which can interfere with the signal. Additionally, big buildings as well as parking garages can block RF waves. Building materials, for instance, metal oxide-coated glass, also hinder cell phone signal.
Lead paint blocks wifi
Paint made of lead is material that can interfere with WiFi and cellphone signals. Lead blocks the signals of these two technologies since it is made up of aluminum and copper particles that interfere with the signal. These particles could block signals from all kinds of technologies. It isn't the only material that blocks wifi and cell phone signals. Aluminum foil also functions as an effective shield. The ability of aluminum foil 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 under federal law. According to the law, it is illegal to make use of the signal jammers within public spaces and at home. The majority of cell phones and wifi technologies operate on 2.4GHz and 5GHz frequencies. It is however possible to use special paint to block these frequencies up to 100 GHz.
Fiberglass insulation can block cell signalling from cell phones
Fiberglass insulation can be an effective method to block cell phone signals. It is lighter than other materials such as concrete or brick, however it is able to still effectively block cell signals. Fiberglass will also help to keep temperature and cold within the home while keeping cell signal from getting out. Fiberglass blocks the signals by absorbing the heat and blocking the signal.
It also blocks the sound that travels through drywall. Fiberglass insulation is light and is easy to put in. It can effectively block cell phone and wifi signals. It is also green and fire-resistant.
