Problem: NON-AUTHORIZED WIRELESS COMMUNICATION IN PRISONS
The control over the incoming and outgoing communication of prisoners is one of the most crucial detention conditions.
Many examples can be found of prisoners using mobile phones to break out of prison and cause serious problems.
Current means of control, from metal detectors to detection systems, have failed and a working solution urges itself.
Solution: PERMANENT BLOCKING
In order to make sure that prisoners are never able to communicate freely with the outer world, the permanent blocking technique has to be applied. Even if mobile phones find their way into a prison, they can simply never be put to use.
In view of legal regulations ISDG focuses its activities on penitentiary institutions.
