A scrambler or encryption module is a small device that installs inside of a two-way analog radio. For digital technologies, it may be a software add-on for a P25 radio. Modules can be retrofitted into existing analog radios or can be installed into any new radios that maybe added to a radio system. When a radio system is equipped with scrambling, listeners will hear a garbled and unrecognizable speech. With the highest levels of encryption, users will hear only “white noise.” When used it the coded mode, radio communications become private to only those who need to know.
By installing a scrambler or encryption module in a two-way radio and then using the radio in coded mode when privacy is desired, communications can be kept confidential. Tactical military operations need to be executed in confidence. No one wants the media showing up to an accident or crime scene before public safety personnel arrive. Today, there is also the possibility of terror threats, which unfortunately can occur anywhere and at anytime. Voice privacy is also essential to critical situations such as bomb threats at a county office, campus shootings or a family hostage situation. These are just a few examples of situations where you want to assure that your communications are protected. Lives of the public, officers and soldiers could be depending on it.
When it comes to personal data, privacy is now becoming the law. It is critical that an injured person’s or even a suspect’s/convict’s personal information is kept confidential. Regulations regarding the protection of private information are becoming increasingly stringent. For example, when radioing into a hospital, ambulance drivers may need to transmit data about a person that is considered private. To comply with privacy laws, a person’s personal data needs to be protected from eavesdroppers listening in on radio communications.
