In recent years, ICT has continued to develop. Among them, mobile phones or mobile phones have completely changed our communication methods and daily life. Nowadays, mobile phones have been widely used. The normal frequencies and commonly used frequency bands include GSM, CDMA, DCS and PCS. Now, with the rapid development of high technology and 3G signals, 4G is also entering the market. These types of frequency bands have been widely used in countries around the world.
If NICT brings us comfortable and convenient communication, we will regret the ability of some people who transfer these technologies from their main function to commit civilized and even more serious, malicious or terrorist acts. Therefore, in this case, cell phone jammer can provide people with a lot of help.
