KIRINTEC are planning an upgrade of the company’s SPECIAL FORCES JAMMER (SFJ), extending the number of jammers that can be hosted on a single jamming network. The SFJ is a man-pack system designed to provide communications jamming across a range of circa five to seven kilometres (3.1 miles to 4.3 miles) encompassing communications jamming in the 20 megahertz (MHz) to six gigahertz (GHz) range. This allows the SFJ to jam a wide array of military and civilian tactical radio systems, wifi and cellphone coverage, providing not only capabilities against conventional communications, but also for high band High Frequency, and also Very and Ultra High Frequency systems such as civilian remote controls for garage doors, for example, which can be used to trigger Improvised Explosive Devices.
The SFJ contains an integral Semtech LoRa tactical radio which provides the SFJ’s KINESIS network across a 433MHz to 868MHz waveband, allowing the SFJs to be linked together on a wireless network. This network, and the jammers therein, can be controlled using a tablet. The company told MONS that it can currently host up to 16 SFJs on a single network, although expects this to be expanded to up to 128 jammers thanks to enhancements which will be concluded in the next two months.
In addition, the company produces its EXCHANGE tactical communications system which uses an innovative ‘Communications through Inhibition’ technique. This allows special forces troops to communicate across a channel which is simultaneously being jammed, with only a ten percent reduction in jamming and communications efficacy. The EXCHANGE provides a channel bandwidth limitation of 45 kilohertz which, importantly, will not degrade voice coverage; the company expects this bandwidth to increase in the near future. The user can plug their own tactical radio into the EXCHANGE system thus facilitating protected communications. The company added that the EXCHANGE is “radio, frequency, encryption and frequency-hopping agnostic.” Other planned enhancements include expanding the envelope of tactical radios that can be used with the EXCHANGE system.
