Using Jammers to Enforce Security Policies
Jammers can protects against breaches of security policy. Cell phones are innocent looking communication devices, but they enable continuous transmission of audio and data. In secured places, where policy does not warrant the use of mobile phones, it is almost impossible to detect a person conducting cell phone conversations or other misuse. Examples of places where cell phone use may not be allowed include:
- Businesses (conferences, board of directors rooms, seminars, meeting rooms)
- Government Building and Government Complexes
- Law Enforcement Facilities, such as Police Stations
- Correctional Facilities, incuding Prisons
- Courts of Law and Court Houses
- Embassies
- Military Installations, Military Complexes, and Military Training Centers

Cell phones — after some slight modifications – can be used as ‘bugging’ devices. A business espionage operator could conveniently ‘forget’ this suitably modified cell phone in the boardroom of a target company. This ‘innocuous looking, ubiquitous object’, could then be called from anywhere in the world (without giving a ringing tone, and with its screen remaining blank) to enable the intruder listen to an otherwise confidential conversation.
Ben Te’eni and Gil Israeli are the co-founders of Netline Communications Technologies. Their activities in the design of cell phone detectors and jammers began when they realized that there was a market for counter-espionage associated with the use of cell phones. Their first cell phone jamming product was a device designed to prevent cell phone communications in selected areas of a building or open space.

On the more questionable end of the legitimacy spectrum, I’ve heard that some hotel chains install jammers to block guests’ cell-phone usage and force them to use in-room phones at high rates. Anybody run into that?
