How to Block Cell Telephone Calls on the Phone
If you wish to block calls from cell phones to your cell phone you have a few choices. First, you can utilize Nature as a blocking agent. For example lead paint is used to block signals from cell phones. Additionally, vehicles and buildings can block wireless signals. Lead paint can also be used to block WiFi signals. There are also options to block cell phone signals from coming into your home.
Nature can block signals for cell phones
For rural locations, signals from cell phones are often blocked by the geography. The terrain is mountainous, the vegetation is dense and severe weather conditions can all block cell signals. In these locations the cell signal providers might offer less coverage or signal disappear 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 popular material used in construction that blocks cellphone signals. Plaster absorbs radio waves and cutting down their energy. Plaster blocks cell signals by about 10 dB. However, this type of material isn't effective at block signals from wifi.
Building materials can hinder cell phone signals
The typical house is comprised of a variety of materials that could hinder cellphone signals. In particular, concrete can greatly reduce the signal received by smartphones. Furthermore, concrete is extremely dense, and it can block wifi signals. This can result in signal loss of -30dB or more, depending on the region.
Wood, particularly the inside frame, can cause problems with reception for cell phones. Although softwoods won't be the same as woods made of harder materials however, they will significantly reduce the signal. Likewise, concrete is utilized to support buildings and while it can withstand enormous weight, it can also interfere with the signal.
Apart from metal and wood and other metals, other materials may interfere with the signals of cell phones. Fiberglass, for example, is more brittle than other materials and repels cell phone signals. No matter what material you choose it is important to select building materials that don't interfere with cell signals.
Cars can block cell signalling
Cars have a lot of metal in them. This could block signals from cell phones. There are also windows that are coated with a coating to block signals from cell phones. In a car, it can be a unsafe place for drivers and passengers to talk on the phone. Some cars are designed to block signals at certain frequencies to prevent driver distraction.
The construction of buildings can hinder cellphone signals. Concrete and metal aren't good conductors of RF waves, which can interfere with the signal. Also, large buildings and parking garages can deflect the RF signals. Building materials, like glass coated with metal oxide, can cut down cell phone signals.
Lead paint blocks WiFi
Lead paint is a material that could cause interference with WiFi and cell phone signals. Lead paint blocks signals from these two technologies since it contains copper and aluminum particles that block the signal. Those particles can block signals from various technologies. It isn't the only material that can block cell phone and wifi signals. Aluminum foil also functions as an effective shield. Its ability to block these signals first was discovered by Michael Faraday in 1836.
Lead paint used to stop wifi and cell phone signals is illegal in a majority of countries. It's also a violation the federal laws. According to law, it's not legal to employ signal jammers in public places as well as in private homes. The majority of cell phones and wifi technologies operate on 2.4GHz and frequencies of 5GHz. However, it is possible to paint with special colors to block these frequencies up to 100GHz.
Fiberglass insulation can block cell signalling from cell phones
Fiberglass insulation is an effective method to block cell phone signals. This type of insulation is lighter than other materials, such as concrete and brick, however it is able to still effectively block cell signals. Fiberglass can also help keep heat and cold inside the home while keeping cell signals out. Fiberglass blocks signals by absorbing the heat and block the signal.
It can also block the sound that travels through drywall. Fiberglass insulation is light-weight and is easy to put in. It is able to block wifi and cell phone signals. It is also eco-friendly and fire resistant.
