Mobile Phone Jammers - Misuse feared
Mobile phone jammers are in demand and its sales have gone up in the city. Jammers come with a minimum price of Rs 9,000. Both portable and fixed jammers are available in the market.
The low quality jammer can block phones within 20 meters. Prices will go up corresponding to the larger limit above 20 metres. High quality jammers can be able to block phones beyond the limit of 200 metres.
In fact, the equipment is not supposed to be used by ordinary people. A telephone jammer is an instrument used to prevent cellular phones from receiving signals from base stations. When it is active, the jammer effectively disables cellular phones.
The jammers are used where high security is needed such as courts, jails, confidential meetings, parliament and so on. In many countries, use of jammers is illegal mainly due to safety hazards as all calls will be blocked, including the emergency calls.
In India, though the use of jammers is legal, it is restricted to government offices, religious places, prisons and educational institutions.
Shops selling these jammers in the city say that ordinary people come asking for jammers these days. They say parents come for the jammers to prevent the use of mobile phones by their children during their study time.
But, sources say that the users are mainly those who are engaged in anti-social activities. In Kerala, Malappuram is the prime market. In Thrissur district, demand is very high in Guruvayur and Chavakkad areas.
According to sources, jammers are helpful in carrying out robberies, murders and terrorist activities. People will not be able to contact anyone if they are in trouble and criminals can take advantage of this situation to fulfil their aims.
Assistant City Police Commissioner TK Thomas told City Journal that mobile phone jammers are meant to use in high security areas. "There is no need for commoners to use such systems. If someone uses and sells jammers, it should be with approval from police,'' Thomas said.
Cyber Cell in the city said that the use of mobile jammers should be with consent from police or Cyber Cell
