Analysis of aggregate cell phone 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.
Also, you’ll need a good RF-testing equipment, an aluminium box, ultra-high frequency connectors which can be found in old phones, 9-volt battery, and a voltage regulator. RF input (which is this port of the mixer) connects to the first 800MHz cell phone antenna, and the RF output is sent to the mini-circuit amplifier. This amplifier increases the output power for 15-16dbm. The amplified signal is then sent to the second cell phone antenna.
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.
Maybe we need to try to DIY a 4G jammer ourselves. Though it may sound like a complicated process making your own cell phone jammer is not really a rocket science. You can make a cell phone jammer at home. Well, let’s start making jammers
“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.”
