The way to Block Cell Phone Calls in your Phone
If you'd like to block cell phone calls on your phone, there are several options. First, you can utilize Nature as an agent for blocking. For example the lead paint has been known to block signals from cell phones. Second, buildings and cars can hinder wireless signals. Lead paint has also been known for its ability to block WiFi signals. Finally, there are options to prevent cell phone signals from coming into your home.

Nature can interfere with signals from cell phones
In rural areas, signals from cell phones are usually blocked by geography. Mountainous terrain, dense vegetation, and bad weather can all block cell signals. In these areas mobile phone signal providers may offer lesser coverage or may not be able to transmit completely. There are solutions to address the issue. To resolve the issue first, you must find out what's hindering your signal.

Plaster is a typical material used in construction that blocks cell phone signals. Plaster is able to block radio waves and cutting down their energy. It blocks the signals of cell phone by around 10 dB. But, this kind of material is not effective in stopping wifi signal.

Building materials could hinder cell phone signals
The typical house is comprised of numerous materials that can hinder cell phone signals. Concrete, in particular, could significantly cut off the signal from a smartphone. Concrete is also extremely dense and may interfere with wifi signals. It can cause signal loss of 30dB or more, based on the area.

Wood, specifically the interior frame, can also cause a problem in cell phone reception. Although softwoods won't be the same as woods made of harder materials but they could significantly decrease the signal. Likewise, concrete is utilized to support buildings and while it can support 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. anti emf clothing , for example, is not as dense as other materials and repels cellular signals. Regardless of the material it is important to use building materials that do not interfere with cell signals.

Cars are able to hinder cell phone signals
Cars have a lot of metal in them and that can block cell phone signals. There are also glass coatings which block cell signals. Cars can be danger for drivers as well as passengers to talk on the phone. Certain cars are built to block signals at certain frequencies to avoid distraction by drivers.

Buildings can also hinder cellphone signals. Concrete and metal aren't good conductors of RF waves that can block the signal. Furthermore, large structures and parking garages can deflect the RF waves. Building materials, such as metal oxide-coated glass reduce cell phone signal.


Lead paint blocks WiFi
Lead paint is a material which can cause interference with WiFi and cellphone signals. Lead can block the signals of these two technologies due to the fact that it contains copper and aluminum particles that could hinder the signal. These particles could block signals from various technologies. It isn't the only material that can block cell phone and wifi signals. Aluminum foil also acts as a shield. Its ability to block these signals was first discovered by Michael Faraday in 1836.

Leaded paint is used in the use to hinder wifi and cell phone signals is not legal in many countries. It's also a violation the federal laws. According to the law, it's illegal to employ the signal jammers within public areas as well as in private homes. Most cell phone and wifi technologies use 2.4GHz and 5GHz frequencies. However, it is possible to apply a special paint to block the frequencies to 100GHz.

Fiberglass insulation could block cell phone signals
Fiberglass insulation can be an effective way to block cellphone signals. It is lighter than other materials such as concrete or brick, however it is able to still effectively block cell signals. Fiberglass can also help keep heat and cold inside the house while keeping the cell signals out. Fiberglass blocks the signals by absorption of the heat and block the signal.

It can also block sound from passing through the drywall. Fiberglass insulation is light-weight and easy to install. It effectively blocks wifi and cell phone signals. It is also environmentally friendly and fire resistant.
