Example of a mobile phone jammer, produced by Jammerspro. A mobile phone jammer or blocker is a device which deliberately transmits signals on the same radio frequencies as mobile phones, disrupting the communication between the phone and the cell-phone base station, effectively disabling mobile phones within the range of the jammer, preventing them from receiving signals and from transmitting ...
An international mobile subscriber identity-catcher, or IMSI-catcher, is a telephone eavesdropping device used for intercepting mobile phone traffic and tracking location data of mobile phone users. [1]
When conducting base station surveys, the StingRay mimics a cell phone while passively collecting signals being transmitted by cell-sites in the area of the StingRay. Base station survey data can be used to further narrow the past locations of a cellular device if used in conjunction with historical cell site location information ("HCSLI ...

They usually have a larger jamming radius and wider frequency band. Strong jammers can require additional cooling as they can overheat.
