When  the use of cellular phones contradicts the rules of an establishment and threatens the integrity of the institution.  For example, in a prison where organized crime can continue to run their organizations through the use of cellular phones.

Prisons
The use of cellular phones is normally forbidden in prisons around the world.  As cellular phone devices become smaller they become easier to smuggle into prisons.  Some are so small as to be hidden in body cavities. 

The use of smuggled cellular phones in prisons threatens the integrity of the prison and creates severe pain to prison management because:

§         Criminal Punishment Is Minimized: Organized crime figures continue to run their organizations from prison with the use of cellular phones, defeating one of the purposes of incarceration.

§         Safety And Security Is Threatened: Cellular phones have been used by prisoners for command and control during prison riots.  In some cases coordinating not only a single prison, but also simultaneous riots in multiple prisons.

§         Criminals Get Rich: Cellular phone calls can be “sold” for as much as $500 to $1,000 per call inside a prison – creating a multi-million dollar industry supporting crimes within the prison system itself. 

Voting
In many jurisdictions around the world there are unscrupulous people who attempt to purchase votes from voters with no money.  A common occurence is to offer them money in exchange for a picture of their completed ballot - and supply them with the cellular camera phone to take the picture and send it outside before depositing in the ballot box.

In Korea a major national scandal was recently uncovered by hundreds of students cheating on national college entrance exams using cellular phones. 

www.France24.com reported on June 1st 2007 that almost 2000 Nigerian students cheated on exams with mobile phones in Nigeria

Cell-Block-R Control Units are appealing for all level schools where talking on a cellular phone or cellular phone ringing is disruptive.  Initial penetration into the school market would be best at the university level because, as a rule, there is more funding available.  The negative perception of cheating can also be higher for a bar exam for lawyers than for a mathematics final in high school.

In Germany, students have sent text questions for such things as the date of a historical event or formula for figuring the area of a circle, and a text reply supplies the answer.  Great if you’re studying at home and you’re stuck, say teachers.  Less good if you’re using the service during a closed-book exam.  Cell-Block-R Control Units can prevent cheating on exams via cellular phones. 

Court Rooms
Cellular phones when used in a courtroom setting can and do disrupt the legal proceedings from their ringing and the talking.

In court proceedings that are private, cellular phones can be used to transmit the proceedings in real time to the outside world without being noticed.

Photos taken of witnesses can be used for intimidation or blackmail.
