Please Note:  All Jamming devices in part or whole may be regulated by the US Department of State in accordance with the guidelines of ITAR (International Traffic in Arms) title 22, Code of Federal Regulations (CFR), Parts 120-130. An export license may be required before proceeding. RF Jamming in some countries is regulated. In the United States, RF Jamming is prohibited by the FCC. Using an RF Jammer without FCC permission is a violation. Some Federal Agencies and US Armed Forces may be exempt.

Deployments include stopping criminals make cell phone calls, either in prison, bank robbery, hostage standoff, etc. Drawbacks using omni-directional RF Jammers consist of cellular service outages that effect neighboring buildings and communities.

For this reason, HSS has designed proprietary directional RF jamming systems to jam prison cell phones.

The issue of over-jamming an area has prompted HSS to include both directional RF jamming and Managed Access solutions for correctional users of RF Jammers, as well as Government agencies who wish to restrict communications.

RF Jamming solutions include:

  • The Detector Jammer, a device that senses a mobile cell phone's activity and then reacts by jamming the frequencies of that phone
  • Power-selectable RF Jammers, a hybrid of the MS3 Jammer and the MS6 Jammer, permit the user to increase or decrease the signal jamming power output for stabilized control over the jamming radius
  • Unique directional antennas, designed into the housing of wall mounted RF Jamming systems. This permits RF jamming efficiency for increased saturation of 'threat areas' deemed vital for targeted jamming operations. This involves focusing the jam wave on areas deemed unauthorized to use prison cell phones.

Signal jamming can work in one direction with a directional antenna, or in all directions with an omni-directional antenna to block radio signals, and prevent cell phone service.

An RF Jammer can be used in a building, mounted on a wall, operate stationary in a rack-mounted cabinet, or made portable for use while moving. In a prison, it can work standalone or in a networked configuration with other RF Jammers.

RF Jammers are used to block radio signals. In a prison, RF Jammers can stop cell phones from getting service by severing the link between the cellular phone and the local wireless phone carrier with signal jamming.

HSS creates solutions to detect and react to cellular phones (in any  frequency).
