Target Applications




There are or there will be in the next few months one billion cellular phone users worldwide. Each mobile phone has many corrupt or malevolent applications that can turn it into an eavesdropping device or interference device.



With features such as vibrating ringers, ear devices, auto answering mode, compactness and the increasing number of internal plastic components, cellular phones become undetectable and allow for a call to occur virtually undetected.



Therefore, it becomes more and more essential to implement in sensitive locations a usage policy forbidding the use of cellular phones in sensitive locations and premises.



But usage policies are in many cases not enough to limit the use of cellular phones. The only efficient way to be sure that the policy is applied, and that no one is using a mobile phone for malevolent applications, is to prevent its usage through the installation of a BlockPhone in sensitive premises.



BlockPhone system helps you to increase your security level in security and military applications, enhanced EMI/RFI protection for critical equipment or acoustic isolation.
