• Cell phones present a significant safety risk by allowing collaborators in coordinated attacks (such as the recent terrorist attack in Mumbai) to communicate freely. Traditional jammers shut down all signals and prevent law enforcement from communicating with one another. Zone of Silence can shut down dangerous transmissions while keeping law enforcement lines open.

  • A Los Angeles Metrolink Engineer was texting 22 seconds before his train crashed head on with another train, killing 25 people and injuring 130 others on Sept. 12, 2008.
