How you can Block Cell Phone Calls on Your Phone
If you wish to block phone calls made by cell phones from your mobile, you have a few options. You can first use Nature as an agent to block calls. For instance, lead paint is known to block signals from cell phones. In addition, cars and buildings could hinder wireless signals. Lead paint is also 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 cell phone signals
Rural areas are where cell phone signals are often blocked by the geography. Mountains, dense vegetation and weather-related issues can all block cell signals. In these locations, cell phone signal providers may offer lesser coverage or may not be able to transmit altogether. However, there are options to address the issue. To correct the issue it is first necessary to determine what is the issue that is preventing your signal.
Plaster is a common building material that can block cellphone signals. Plaster absorbs radio waves and cutting down their energy. Plaster blocks cell signals by around 10 decibels. However, this type of material is not effective in blocking wifi signals.
Building materials can hinder signals for cell phones
A typical home is made of a variety of materials that could interfere with the signals of cell phones. In particular, concrete can greatly reduce the signal of a smartphone. Furthermore, concrete is extremely dense and can interfere with wifi signals. It can cause signal loss of -30dB or more, based on the region.
Wood, specifically the interior frame, can also cause a problem in cell phone reception. Although softwoods won't be as bad as harder woods however, they will significantly reduce the signal. Concrete is also used to support structures, and while it can withstand tremendous weight, it will also interfere with the signal.
Besides wood and metal and other metals, other materials may interfere with cell phone signals. Fiberglass, for example, is more brittle than other materials, and can block cellular signals. Whatever the material it is essential to select building materials that don't interfere with cell signals.
Cars can block cell phone signals
Cars are stuffed with metal in them. This could block signals from cell phones. There are also some window coatings that block cell signals. A car can be a dangerous place for drivers and passengers to talk on the phone. Certain cars are built to block signals at certain frequencies to avoid distraction by drivers.
The construction of buildings can block signal transmissions from cell phones. Concrete and metal are not excellent conductors of RF signals, which can interfere with the signal. Additionally, big buildings as well as parking garages can block RF waves. Building materials, such as metal oxide-coated glass reduce cell phone signals.
Lead paint blocks wifi
The lead paint can be a product that could cause interference with WiFi and cell phone signals. Lead blocks the signals of these two technologies because it contains copper and aluminum particles that can interfere with the signal. These particles could hinder the signal of all kinds of technologies. The lead is not the only material that can block cell phone and wifi signals. Aluminum foil also acts as shielding. Its ability to block signals first was discovered by Michael Faraday in 1836.
Lead paint used to block cell phone and wifi signals is illegal in many countries. It's also a violation the federal laws. According to the law, it's illegal to use the signal jammers within public places and at home. The majority of cell phones and wifi technologies operate on 2.4GHz and frequencies of 5GHz. However, it is possible to use special paint to block the frequencies to 100GHz.
Fiberglass insulation could block cell phone signals
Fiberglass insulation can be an effective method to block cell phone signals. It is lighter than other materials such as concrete or brick, but it can still block cell signals. Fiberglass can also help keep temperature and cold within the house, while keeping cell signal out. Fiberglass blocks signals by absorbing the heat and block the signal.
It also blocks sound traveling through drywall. Fiberglass insulation is lightweight and easy to install. It can effectively block cell phone and wifi signals. It is also eco-friendly and fire-resistant.
