Make or buy a phone jammer

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 […]

Interference devices have been used in various fields

A jamming pod is essentially filled with antennae and radar transmitters. This equipment is vital for a warplane to survive modern combat. The first fight of every mission — a bombing run, surveillance or dogfighting — is waged across invisible parts of the electromagnetic spectrum. Radar can overpower other radar, sensors can be spoofed with […]
