How do cell phone jammers work?
Mobile communication is two-way communication. A sender sends a signal through its mobile to the base station, and the base station further transmits the signal to the receiver. The jammer signals work so that it transmits at the frequency equal to the mobile movement. There comes the point when the jammer signal overpowers the mobile signals and blocks the transmission of the signal to the receiver.
The cellular or cell phone jammers either block the signal’s transmission or create noise during an ongoing call. The jammers work not only to disrupt a call; rather, they also stop the messaging service between two entities.
