Cell phone jammer: A device used to disrupt communication by means of mobile phones. [e]
This article contains just a definition and optionally other subpages (such as a list of related articles), but no metadata. Create the metadata page if you want to expand this into a full article.
Parent topics
- Cellular telephony [r]: Add brief definition or description
- Electronic warfare [r]: A subset of information operations that deals with the use of electromagnetic or kinetic means to degrade an enemy's military electronics systems, to be able to operate one's own electronics in the face of enemy attacks, and to evade those attacks through protection or deception [e]
- Electronic attack [r]: A subset of electronic warfare that actively interferes with the operation of hostile systems; previously called electronic countermeasures (ECM) [e]
- Electronic protection [r]: A part of electronic warfare which includes a variety of practices which attempt to reduce or eliminate the effect of electronic countermeasures (ECM) on electronic sensors aboard vehicles, ships and aircraft and weapons such as missiles. [e]
Subtopics
- AN/ULQ-30 [r]: A mobile system for collecting information on electronic transmitters and optionally jamming them, developed for the United States Marine Corps giving capabilities to temporarily block cellular telephony [e]
- Faraday cage [r]: Add brief definition or description
- Radiofrequency MASINT [r]: Add brief definition or description
- Improvised explosive device [r]: Add brief definition or description
- Sensitive Compartmented Information Facility [r]: A work area with the administrative, physical, and electronic safeguards to allow proper protection of information or materials under the requirements of a compartmented control system [e]
Signal types
- Spread spectrum [r]: A communications technique in which the information to be transmitted travels redundantly over multiple channels (e.g., frequencies, time slots), the number and identity of which may change. It provides greater immunity to noise and electronic attack, makes it harder to intercept, and can increase capacity of a shared medium. [e]
- Frequency division multiple access [r]: Add brief definition or description
- Time division multiple access [r]: Add brief definition or description
- Code division multiple access [r]: Add brief definition or description
