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 cell-phone base station and the mobile phone, effectively disabling mobile phones within the range of the jammer, preventing them from transmitting signals and from receiving signals . Mobile phone jammer can be used in practically any location, but are found primarily in places where a phone call would be particularly disruptive because silence is expected, such as entertainment venues.
Blocking single callers can be an annoying time waster. Mobile Phone Jammer remove that annoyance by blocking all incoming calls at once.
This process might seem complicated but it’s actually fairly simple. They release a signal that is at the same frequency as a cell phone’s signal. The Mobile Phone Jammer then broadcasts that signal out to the world. If it’s successful, cell phones will no longer receive signals in a particular location.
There are several reasons people use Mobile Phone Jammer. Business owners may want to block their employee’s cell signals to prevent workplace distractions or interruptions during meetings.
Mobile Phone Jammer also prevent cell phones from sending outgoing information. People might use a Mobile Phone Jammer as a safeguard against sensitive information leaking. It’s also been a useful method for blocking signals to prevent terrorist attacks.
People also like using Cell Phone Jammer because they give an “out of service” message instead of a “phone is off” message. This makes the cell phone owner seem unreachable to a caller. There are a number of different devices available that can jam calls just like that.
Because they disrupt the operations of legitimate mobile phone services, the use of such blocking devices is illegal in many jurisdictions, especially without a licence. When operational, such devices also block access to emergency services.
