They can be grouped as follows: cell-phone-jammer-for leisure and general-purpose-work; Portable-cell-phone- jammer; Remote-control-cell-phone-jammer – where jamming does not necessary have to be from the area where the device is located; Adjustable-cell-phone-jammer; School & prison-phone-jammer - to prevent cheating in examinations and destructions during lectures as well as illegal use in prisons; Explosion-proof cell- phone- jammer - to curb RF-triggered bombs; and Police & military phone-jammer -to prevent illegal-activities like by kidnappers trying to extort money from citizens or criminals planning an illegal activity. This-design is focused on the School & prison-cell-phone-jammer. Of course, now honeycomb interference equipment application is more and more widely, such as cinemas, private companies, library and other places also began to use this kind of equipment.

A cell phone jammer works because, when you think of it, cell phones are “basically two-way handheld radios.” And the cell phone, like a radio, needs to send a signal to a nearby tower that is then passed along to the individual on the other end of the line in order to work. A new bill circulating through Congress would allow prisons to use cell phone jamming technology to block illicit cell phone traffic from inside prisons. Sponsored by Senator Kay Bailey Hutchinson (R-TX), the bill would amend the Communications Act of 1934 to allow state prisons to petition the Federal Communications Commission to use cell phone jamming equipment to block cell phone signals inside their buildings. Many countries allow limited cell phone jamming, including France, India, Mexico, New Zealand and others. Nearly all these countries allow the jamming of cell phones in prisons. Some of them allow it in schools, and even theaters. Many countries with current bans are considering the use of jammers in prisons.
