This jammer will work later to remove the signal and eventually they will disband on their own and later we will also cooperate with Telkom," Deni said at the Garut county government secretariat live, quoted from Antara on Monday.

How cell phone jammer work

Jammers work by sending radio frequency signals to the nearest BTS tower. The signal is basically on the same frequency as a cell phone, and strong enough to cover it.

The jammer signal and the cell phone signal eventually collide, and the process then causes a loss of communication between the cell phone and the base station.

Depending on the make and model, jammers come in different variants and capabilities. Common jammer devices block one of two cell phone frequencies, tricking the phone into thinking it doesn't have BTS service because it only receives one frequency.

Phone screens covered buy jammers may display the words "Out of service".

However, a new technology version of the jammer can block multiple frequencies and even adjust to match the target frequency.

The Ministry of Communications and Information has banned the use of gps blocker or items that may interfere with signals/frequency propagating within Indonesia. Jammers that are not in the national interest will be confiscated, and the assemblers and sellers will be prosecuted.

This is under Law No. 1. Decree No. 36 of 1999 on Telecommunications prohibits the circulation of goods in Indonesia that interfere with signals/frequency.
