The development trend of global jamming technology

The deep application of signal jammer technology

The US Navy’s Next Generation Jammer, promises a new, more capable electronic warfare system that combines agile, high-power beam-jamming techniques and state-of-the-art solid-state electronics. Dr Gareth Evans takes a closer look.

The report recommends that quantitative engineering criteria for jammer effectiveness against contraband wireless devices and for harmful interference to nontargeted CMRS receivers need to be developed if jamming technology is to be further developed for application in prison environments. Possible future aggregations of multiple wifi jammer units, as would be required to cover entire prison facilities, would produce higher total levels of aggregate power than were measured for the one jammer device at Cumberland FCI.

Analysis of aggregate jammer emissions at prison facilities is beyond the scope of the report, as aggregate analysis would require detailed knowledge of specific facilities’ physical characteristics, the exact placement of individual jamming transmitters within such facilities, and the exact electronic characteristics of the jamming transmitters.

Billed as the only operational tactical jamming fighter in the world, the Growler is a specialised version of the F/A18-F Super Hornet, and since achieving initial operational capability in September 2009, it has been equipped with the AN/ALQ-99 airborne EW system. The AN/ALQ-99 itself, however, can claim much older ancestry, having been designed in the late 1960s, and first fielded in 1971with the introduction of the EA-6 Prowler, the EW variant of the A-6 Intruder, in time to see combat service in Vietnam.

“These promising test results mark a step forward countering the security threat posed by contraband cellphones,” said Assistant Attorney General Beth Williams of the Justice Department’s Office of Legal Policy. “The results indicate the potential for localized impact of this micro-jamming technology. That is an encouraging sign that brings us closer to a solution that will make our communities safer and help prevent the continuation of criminal activity from inside prison walls.”

The data in the report will be used by BOP and the Department to understand the efficacy of micro-jamming, conduct further evaluation of jamming technology, and develop recommendations for strategic planning.

The device is capable of obstructing telecommunication protocols between the drone and its remote control. Moreover, the Nerod F5 allows to ensure frequency hopping communication systems. In fact, this device is effective against UAVs, IEDs (jamming the triggering instruction given by GSM or radio control) and various communication protocols.
