Wireless jammer or signal jammer intentionally jams or blocks authorised signals.
The Department of Telecommunication (DoT) has issued an advisory to the general public on the proper use of wireless jammer and booster or repeaters.
It said that unless specified by the Centre, the use of such jammer, GPS blocker or other signal jamming device is “generally illegal”.
Big points from the advisory:
- Private sector organizations and/or private individuals cannot procure/use jammers in India.
- It is unlawful to advertise, sell, distribute, import or otherwise market jammers in India.
- It is unlawful to possess, sale, and/or use mobile signal repeater/booster by any individual/entity other than the licensed telecom service provider.
On January 21 this year, the telecom department had warned all e-commerce companies from selling or facilitating the sale of wireless jammers on their platforms. The direction was issued after the Centre noticed that some e-commerce platforms were facilitating the sales of wireless jammers which are capable of disrupting the authorised telecom and other wireless networks.
