How to Block Cell Mobile phone Calls on Your Phone
If you'd like to block cell phone calls on your phone, there are several options. You can first make use of Nature as an agent for blocking. For example, lead paint is known to block cell phone signals. Additionally, vehicles and buildings are able to hinder wireless signals. Lead paint is also known to block WiFi signals. In the end, there are options to block the signals of cell phones from coming into your home.
Nature can interfere with signals for cell phones
For rural locations, cell phone signals are often blocked by the terrain. Mountains, dense vegetation and severe weather conditions could all interfere with cell signal reception. In these regions mobile phone signal providers may offer lesser coverage or may not be able to transmit completely. However, there are options to solve the issue. To fix the problem first, you must identify the issue that is blocking your signal.
Plaster is a popular material used in construction that blocks cell phone signals. Plaster is able to block radio waves, thereby cutting down their energy. It blocks the signals of cell phone by approximately 10 dB. But, this kind of material is ineffective at block signals from wifi.
Building materials can block signals for cell phones
The typical house is comprised of a variety of materials that could interfere with cell phone signals. In particular, concrete could significantly cut off the signal received by smartphones. Furthermore, concrete is extremely dense and can interfere with wifi signals. This could result in signals being lost by -30dB or more, based on the location.
Wood, specifically the interior frame, can also cause a problem with reception for cell phones. While softwoods aren't the same as woods made of harder materials but they could significantly decrease the signal. Concrete is also utilized to support buildings and while it can withstand enormous weight, it can also interfere with the signal.
In addition to metal and wood, other materials can also interfere with signals from cell phones. Fiberglass, for instance, is more brittle than other materials and blocks cellular signals. No matter what material you choose it is important to choose building materials that don't interfere with cell signals.
Cars are able to hinder cell phone signals
Cars are stuffed with metals in them, and this can block cell phone signals. There are also window coatings that block cell phone signals. Cars can be danger for drivers as well as passengers to use the phone. Some cars are designed to block calls at specific frequencies to avoid distraction by drivers.
Buildings also block signal transmissions from cell phones. Metal and concrete are not excellent conductors of RF signals that can block the signal. Furthermore, large structures and parking garages can deflect the RF waves. Building materials, such as metal oxide-coated glass cut down cell phone signal.
Lead paint blocks WiFi
Lead paint is a material which can cause interference with WiFi and cell phone signals. Lead paint blocks signals from these two technologies because it contains copper and aluminum particles that could interfere with the signal. Those particles can hinder the signal of any technology. Lead is not the only substance which can block wifi and cell phone signals. Aluminum foil also functions as shielding. The ability of aluminum foil to block signals was first discovered by Michael Faraday, in 1836.
The use of lead paint to block cell phone and wifi signals is not legal in a majority of countries. It's also an infraction the federal laws. According to the law, it's illegal to make use of signal jammers in public spaces as well as in private homes. The majority of wireless and cell phone technologies operate on 2.4GHz and frequencies of 5GHz. However, it is possible to use special paint to block these frequencies up to 100 GHz.
Fiberglass insulation could block cell phone signals
Fiberglass insulation is an effective method to block cell phone signals. This type of insulation is less dense than other materials such as concrete or brick, yet it can still effectively block cell signals. Fiberglass also helps keep the heat and cold inside the house, while keeping cell signal out. Fiberglass blocks the signals by absorbing the heat and blocking the signal.
It can also block sound traveling through drywall. Fiberglass insulation is light and is easy to put in. It effectively blocks wifi and cell phone signals. It is also eco-friendly and fire-resistant.
