New Delhi: Indian agencies have for some time, noticed infiltrating militants from Pakistan carrying smart phones without SIM cards. Interrogation of Sajjad Ahmed revealed that it is a new technology that is being used to evade Indian eavesdropping. The tech improvisation was originally prompted by the devastation of Hurricane Sandy in 2012 in the New York area, and helped to maintain communication even mobile towers were down.

Indian agencies can today listen in on VHF conversations, mobile phones and satellite phones and this has helped them neutralize the militants rather effectively. The technology uses VHF (very high frequency) and helps avoid the eaves drop especially during the crucial hours when they cross the Line of Control.

The technology is to pair a smart phone with a radio set, and send out short SMS’s, an SOS appeal or the exact location to other paired devices using line-of-sight very high frequency.

This technology works even in high peaks and ravines, especially near the Line of Control where conventional mobile and satellite phones can give away their exact location.

Ahmed, who was captured from Rafiabad area, in August gave the game away. He said the militants call it YSMS communication application. When Abu Suhaib, one of the militants in the infiltrating group and technology expert among them, was sure to be killed by the Indian Army on August 27 he tried to break up the system, However, Ahmed stopped Suhaib from fully destroying it. The Army later recovered the Samsung mobile phone and the wireless set paired to it for YSMS.
