When it comes to preventing prank callers, blocking cell phone signals can be a very useful technique. With today's technology, cellular phones are capable of so many different things and not all of them are what you want. If you're tired of getting annoyed at the constant ring in your ear, take this opportunity to make your home safer by blocking certain cell phone numbers from being able to reach you through your telephone.
The first thing that you will need to consider when learning how to block cell phone signals is if you actually want a wi-fi device for protection or if you prefer more traditional types of protection. One option that you have is a wireless device that is similar to a cell phone jammer. These devices work through a metal or wooden frame that has a small slot in the center. This slot acts like a USB port that connects your device to your computer or laptop. Wireless devices are very popular for people who want more freedom while they are away from their home and even for those who use their devices in environments that they cannot always get to an Internet cafe.

A very common type of metal that you can use to block cell phone signals is wood. There are a variety of woods available for blocking the signals including cedar, pine, and redwood. These woods often come in kits with a block tab and a few screws to put the unit together. This method works well because the unit has a metal casing and a wooden tab which connects to the metal casing. However, these types of products can be prone to rusting and discoloring if they are exposed to moisture or are exposed to metal sounds while in use.
A second way to block cell phone signals is to purchase a small device called a jammer. These jammer devices resemble a small handheld security device and they work through the same principle. A small coil or metal disc is placed within range of the wireless device. The jammer changes the frequency of the signal so it does not reach the target device. There are many different types of jammer available and they vary in design so you will need to do some research on the specific model you want so you know exactly what you are purchasing.
A final, yet effective way to block cell phone signals is through the process of frequency division and discrimination. Basically, this technique uses two towers. One tower acts as the primary tower and the other tower acts as the secondary or opposite tower. When the two towers detect each other, they then try to determine a common frequency. If they find this common frequency, then they will simply divide the signal into two parts which are then sent to the two devices. It seems like there is quite a bit going on here but the principle behind this is fairly simple.
In short, jamming or blocking mobile phones can be done in a variety of ways and they all accomplish the same end result. What this ultimately means is that you will not be able to make calls when you need to. Cell phones are very tricky pieces of equipment and they are used by people for different purposes. You can purchase various gadgets that are designed to disrupt cell phones so you will not be able to make calls, however these methods are only effective for specific situations. For more information about the topic, you may wish to do a little research on the Internet. There are a wide variety of blogs, articles, and Web sites that can help you understand this intricate topic and give you the information you need to decide for yourself which of these techniques would be the best to block cell phone signals.
