Defence forces, who were last month excluded from the list of agencies eligible to procure jammers, have now been included, in addition to central armed police forces like Central Reserve Police Force, Central Industrial Security Force and Indo Tibetan Border Police.
"Jammers can be procured only by the defence forces, CAPFs, state police and jail authorities," the revised policy issued by the Cabinet Secretariat said.
Defence forces use jammers along the international border and Line of Control to block wireless and telecom signals to check infiltration from across the border.
The new policy surprisingly excludes both internal and external intelligence agencies --Intelligence Bureau and Research and Analysis Wing -- from procuring jammers.
However, central armed police forces fighting militancy in Jammu and Kashmir, Naxalism in some states, and insurgency in north eastern states have, for the first, time been allowed to procure jammers.
Jammers can be bought only by states' police department, jail authorities, and central government's security agencies like RAW and IB, as per the old policy.
The Cabinet Secretariat has evolved norms for procurement and use of jammers by states, union territories, defence forces and central police organisations.
"Private sector organisations and or private individuals cannot procure or use jammers in India. These norms take into account the need to guard against random proliferation of jammers as well as to ensure that jammers installed do not unduly interfere with the existing mobile phone networks," the new norms said.
The guidelines allow statutory examination conducting bodies to deploy "low powered jammers to prevent cheating during examinations".
"The same would not however be through procurement or ownership of the equipment. They would be given permission only to take it on lease basis and would therefore have to pay only for using jammers on the specific date of examination.
"The examination body may consider deployment of jammers in sensitive examination centres based on past experience and other inputs rather than deployment in all centres across the country," according to the new norms.
The permission for procurement of jammers is granted in consultation with Special Protection Group, which guards the prime minister, former prime ministers and their immediate family and Intelligence Bureau that maintains a database of available jammers.
"In case of movement of SPG protectees in the vicinity, all type of jammers procured by government agencies should be deployed in consultation with SPG," it said.
The new policy also bars import of jammers without getting a license from Directorate General of Foreign Trade.
Prior permission of secretary (security) in the Cabinet Secretariat must be obtained before procurement of jammers, it said.
