Now a days there are many  people who are using cell phone. Sometimes we get that our cell phone stops working. Or it get totalled use less. And do you know why this is so. If you want to know all of it then read the below given article whole with carefully.
And here for this purpose or to block the cell phone people use the technology name Cell Phone Jammer. So here we are going to know all thing about the cell phone jammer.

Cell phone jammer is one kind of the technology which can block the entire signal of the cell phone and also stops the work of the cell phone. And also it can jam the reducibility of any kind. It is also used in the field of security too. I think after seeing the word security you could think that it is high tech device. And it is very hard to make it. But in reality it is a simple device and also it is operated in simple principle. And here you also want to make your own jammer then you can easily make it. The work of this jammer is to interfere to the signal that you gain or radio wave, or other devices that you depend upon likes cell phones, remote or also of other communication network like walkie talkie and after that basically the work of the devices will stopped by the effect of that jammer.

This jammer are used in different fields for different purposes and it is of different power ranges too. Here the concept of all are seen same. For eg. If I take about the cell phone then it send signal to the mobile phone tower. So that you get the answer from the tower. Basically it works on the stregs. And it is a complete duplet device it mean that the signal that cell phone either send or receive works simultaneously. Both are in different frequency . So after when you talk then only other can listen you. But in walkie talkie first of all speak then leave then you will listen and then speak and this is called the one way but the cellphone are complete duplet device. And in this the signal which is spreading by the cellphone to the mobile network eg. Just think that you have an another device which is also spreading same signal, then basically the signal spread by cellphone and another strong device will interfere and then the cell phone cannot communicate with the tower, signal of cellphone can't be reach to tower. In this sometimes when the signal is weak then cell phone will increase it power that they can send signal by high power then in this cases the jammer will also increase it power and in this the phone will understand handicap then signal can't be reach in the tower. And in this not only phone, you know that what would be frequency in phone. work in 1900, 800 or anything, in that the jammers can block all the phones and expect this the jammers can also easily block the remote of remote control devices also. And jammer is mostly used in security and we don't want that our phones don't work in any places. It is used in many places for security such as crowdy place. It won't allow any phones to communicate with others. And also it is use in private places. And researchers also have said that sometimes the individuals make their own jammer and used as the source of entertainment for them. Just like think that if I am going to any place in bus then if I have jammer then I will use it not be disturbed  by others who are sitting around me. And you can see in hospitals too. But that are not the jammer they are cell phones alerter. There can be many machines which can be interfered by the signal spread by the cell phone. That cell phone alerter diagnosis whether cell phones are there or not. If there are cell phones then doctor will know there is cell phone. Then doctor will say people not to use that cell phones.
Basically jammer are the simple concept. Here we have to generate the frequency and after that we can increase or decrease the power of the jammer. And also we can add some random noise. And you can completely jam the signals in a range that you want. It can be small or long area. The ranges of jammer depend upon the use like military, security company or other.
So all the given above is all about the cell phone jammer. Share your views on the cell phone jammer. How is it in your views.
